Laryngologists' Reported Decision-Making in Presbyphonia Treatment. J Voice 2024; 38:723-730. [PMID: 34819238 DOI: 10.1016/j.jvoice.2021.10.008] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2021] [Revised: 10/10/2021] [Accepted: 10/11/2021] [Indexed: 11/29/2022]
Abstract
OBJECTIVE Decision-making regarding behavioral versus procedural intervention in the treatment of presbyphonia has not been well defined. The study objective was to survey laryngologists' reported practice patterns and decision-making in presbyphonia. METHODS All laryngology faculty in U.S. academic medical centers with residency programs were recruited to complete an anonymous 29-item survey regarding decision-making in presbyphonia treatment. The survey included 5 sections: demographics, first-line treatment distribution, factors that drive decision-making toward procedural intervention, treatment progression if first-line treatment is insufficient, durable treatment. RESULTS Of 153 laryngologists surveyed, 89 responded (58%). Voice therapy (VT) was the most often reported first-line treatment, with 57% of respondents indicating the majority of their patients receive VT initially. Most respondents (83%) indicated they occasionally use procedural intervention as first-line treatment. Factors driving first-line procedural intervention were severe glottal insufficiency (87%), high occupational/social voice demands (76%), voice not stimulable for change (73%), difficulty attending VT (70%), severe dysphonia (65%), and dysphagia (61%). The majority of respondents indicated the following do not affect their decision to pursue procedural intervention: patient age (88%); medical comorbidities (63%); patient's desire for a "quick fix" (55%); patient-reported outcome measures (51%). Most respondents (81%) use trial injection augmentation before durable treatment. Of durable treatments, bilateral thyroplasty was preferred (71%), followed by CaHA (15%) and lipoinjection (11%). CONCLUSIONS This study is the first to our knowledge to examine factors that influence decision-making in presbyphonia treatment. While VT remains the most frequent first-line treatment, study results better inform decision-making regarding first-line procedural intervention.

The Voice Problem Impact Scales (VPIS). J Voice 2024; 38:666-673. [PMID: 34933795 DOI: 10.1016/j.jvoice.2021.11.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2021] [Revised: 11/17/2021] [Accepted: 11/18/2021] [Indexed: 10/19/2022]
Abstract
INTRODUCTION Patient-reported outcome measures (PROMs) are important for systematically assessing a person's perspectives and experiences with disease to inform clinical decision-making. However, PROMs can occasionally fail to capture subtle differences amongst subgroups. In response to this problem, the aim of the current study was to examine the convergent validity of four patient-reported voice activity and participation scales to better reflect and describe the impact of a voice problem in a patient's work, home, social and overall life. It was hypothesized that augmenting the validated PROM with a directed situational short instrument may enhance patient and clinician communication. This would allow for further description of individual areas of activity limitations or participation restrictions that are relevant to the patient, potentially informing therapeutic goals. METHODS The Voice Problem Impact Scales (VPIS) were developed following the criteria outlined by Francis et al (2016). A retrospective chart review was completed for voice therapy treatment seeking patients at the USC Voice Center. Results from the Voice Handicap Index-10 (VHI-10) and VPIS scores were recorded at the time of the evaluation. Consensus Auditory Perceptual Evaluation of Voice (CAPE-V) assessment was performed by an SLP with fellowship training in voice. RESULTS Three hundred four charts were reviewed, and 198 met inclusion criteria. When considering all patients, VHI-10 scores were significantly correlated with each domain of the VPIS, including overall (R = 0.635, P < 0.001), work (R = 0.436, P < 0.001), social (R = 0.714, P < 0.001), and home (R = 0.637, P < 0.001). For females aged 18-39 and aged ≥60, the VHI-10 was correlated with all domains except work. CAPE-V score was significantly correlated with the social domain (R = 0.236, P = 0.001). Using the corrected significance level, it was not correlated with the overall (R = 0.165, P = 0.022), home (R = 0.197, P = 0.006), or work domains (R = 0.042, P = 0.567). The VHI-10 was not correlated with any of the VPIS domains for males aged 18-39, was correlated with all domains for males aged 40-59, and was correlated with all domains except work for males aged ≥60. Age was the only significant predictor of the work domain (β = -4.631 P < 0.001), with a model fit of R2 = 0.101. CONCLUSIONS Scores from each domain of the VPIS are significantly correlated with VHI-10 scores thus confirming the instrument's convergent validity. There are certain groups for which currently used questionnaires may underrepresent the impact of dysphonia on the patient's life. The VPIS represents a broad tool that might allow the patient to interpret each scale within their individual context and cultural background. The VPIS emphasizes the significance of the dysphonia on quality of life in four common environments. Using this instrument can augment questionnaires and initiate conversations between the provider and patient to determine the area(s) where voice impairment is most important enhancing shared decision-making on therapeutic goals for plan of care.

Adult Normative Data for the OMNI-Vocal Effort Scale (VES). Laryngoscope 2024. [PMID: 38686843 DOI: 10.1002/lary.31464] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2023] [Revised: 03/29/2024] [Accepted: 04/08/2024] [Indexed: 05/02/2024]
Abstract
PURPOSE To establish normative values for the OMNI-Vocal Effort Scale (VES) in healthy adults without voice complaints. Secondary objective is to determine if there are differences in perceived vocal effort across age groups and between sexes. STUDY DESIGN Prospective data collection across groups. METHOD A nine-item survey was administered by speech-language pathologists with specialization in voice to consenting adults 18 years or older. Participants underwent an auditory perceptual evaluation of voice and answered questions regarding age, history of voice problems, history of voice surgery, smoking history and hearing loss. Participants were instructed to rate their perceived vocal effort in conversational speech using the OMNI-VES. Multivariant analysis was conducted. RESULTS Two hundred and fifty-one participants were recruited. The majority of adults without voice complaints reported that producing conversational voice was within the "extremely easy" to "easy" range, 0-3 (92.4%). CONCLUSIONS This study provides preliminary data for perceived vocal effort. The OMNI-VES may be a useful tool in understanding changes in perceived vocal effort as a result of treatment for voice disorders. Further normative data are needed between sexes, across the gender spectrum, and older adult populations. Future directions include examining the magnitude of difference between numeric values on the scale and use of the scale with other dysphonic populations. LEVEL OF EVIDENCE 3 Laryngoscope, 2024.

Indications and Short-Term Outcomes for In-Office Therapeutic Superior Laryngeal Nerve Block. Ann Otol Rhinol Laryngol 2024; 133:174-180. [PMID: 37608685 PMCID: PMC10771019 DOI: 10.1177/00034894231194384] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 08/24/2023]
Abstract
OBJECTIVE Superior laryngeal nerve (SLN) block consists of injection of steroid and anesthetic at the internal branch of the SLN entry site. Prior case series have demonstrated beneficial effects on neurogenic cough. SLN blocks have also recently shown benefit for paralaryngeal pain. We describe short-term outcomes for multiple symptoms of irritable larynx syndrome (ILS) including neurogenic cough, dysphonia related to laryngeal hypersensitivity, inducible laryngeal obstruction (ILO), paralaryngeal pain, and isolated globus. METHODS Retrospective review from 2 institutions of patients undergoing a single SLN block for the indications listed. Variables include age, sex, indication(s), known vagus neuropathy, and patient-reported outcomes at short-term follow-up. RESULTS A total of 209 patients were included (59 males, 150 females; age: 58 ± 13 years). Twenty-six patients (12%) had a history of a vagus nerve injury. Indications included neurogenic cough (n = 149), dysphonia related to laryngeal hypersensitivity (n = 66), paralaryngeal pain (n = 50), ILO (n = 23), and isolated globus (n = 3). Some patients had multiple indications. Significant improvements in patient-reported measures occurred after a single SLN block within 2 to 4 weeks for neurogenic cough (cough severity index; 25.2 ± 11.2 to 19.0 ± 12.8; P < .001), dysphonia (voice handicap index-10; 22.1 ± 12.2-18.0 ± 13.3; P = .005), and ILO (dyspnea index; 21.0 ± 14.9-14.7 ± 15.7; P = .017). Subjective pain improved in 23 of 39 patients with paralaryngeal pain. There was no observed improvement for isolated globus. Presence of known vagal neuropathy or therapy around the time of SLN block did not affect outcome. CONCLUSION SLN block can be an effective component of treatment for a variety of ILS symptoms. Patients may experience some improvement after 1 injection. LAY SUMMARY Symptoms of irritable larynx syndrome, such as neurogenic cough, paralaryngeal pain, inducible laryngeal obstruction, and dysphonia related to laryngeal hypersensitivity can be challenging to manage. In-office Superior Laryngeal Nerve blocks can serve as a quick, well tolerated, adjunctive treatment with positive short-term outcomes. LEVEL OF EVIDENCE 4.

Reliability of Phonemically Loaded Sentences in Spanish for Identifying Laryngeal Dystonia by Non-Spanish Speaking Speech-Language Pathologists. J Voice 2023:S0892-1997(23)00360-0. [PMID: 38036378 DOI: 10.1016/j.jvoice.2023.11.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/16/2023] [Revised: 10/31/2023] [Accepted: 11/01/2023] [Indexed: 12/02/2023]
Abstract
INTRODUCTION Laryngeal dystonia (LD) is a focal dystonia affecting the intrinsic laryngeal muscles. Clinical diagnosis requires subjective evaluation by experienced clinicians and is primarily based on auditory-perceptual assessment. Several speech tasks are widely accepted to elicit diagnosis specific auditory-perceptual symptoms of glottal stops in adductor LD or breathy breaks in abductor LD in spoken English. With the growing Spanish speaking population in the US and lack of Spanish speech tasks to assist in identifying LD in Spanish speaking subjects, assessing the reliability of phonemically loaded sentences in Spanish for use by non-Spanish speaking providers is critical. The first aim of this study was to develop and assess the reliability of a set of Spanish language phonemically loaded sentences designed to elicit signs and symptoms of LD. The second aim was to determine the effectiveness of non-Spanish speaking speech-language pathologists (SLPs) in identifying LD in Spanish speaking subjects using these stimuli. METHODS Phonemically loaded sentences were developed for this study following current guidelines for assessment of LD. Voice samples were obtained from native Spanish speaking individuals. Participant-speakers included 20 people with LD and 20 people without LD who served as controls. All participant-speakers were assessed by a Spanish-speaking laryngologist. Audio samples were presented to non-Spanish speaking SLPs with expertise in working with people with LD who served as raters and classified the samples as either presence or absence of LD. Kappa and the intra-class correlation coefficient were calculated and mixed effects logistic regression was used for prediction. RESULTS The inter and intra-rater reliability indicated statistically significant agreement. Sensitivity, specificity, and predictive values for the diagnosis of LD by the raters were overall strong. CONCLUSIONS Findings demonstrate that non-Spanish speaking SLPs with expertise in the assessment and treatment of LD can reliably identify the presence of LD using Spanish language stimuli in Spanish-speaking individuals. This study supports the use of newly developed Spanish language phonemically loaded voiced and voiceless sentences by English speaking clinicians as an effective tool for identifying LD in Spanish speakers, perhaps mitigating diagnostic delays experienced by patients with LD.

Membranous Vocal Fold Lesions in Patients With Chronic Cough: A Case Series. J Voice 2023:S0892-1997(23)00040-1. [PMID: 36907683 DOI: 10.1016/j.jvoice.2023.02.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2022] [Revised: 02/03/2023] [Accepted: 02/06/2023] [Indexed: 03/13/2023]
Abstract
OBJECTIVES Trauma related to chronic cough and forceful glottal closure has been associated with lesions of the vocal process; however, there is limited description of cough leading to membranous vocal fold lesions. We present a series of mid-membranous vocal fold lesions in a cohort of patients with chronic cough, with a proposed mechanism of lesion formation. METHODS Patients treated for chronic cough with membranous vocal fold lesions affecting phonation were identified. Presentation, diagnosis, treatment strategies (behavioral, medical, and surgical), patient-reported outcome measures (PROMs), and videostroboscopy were reviewed. RESULTS Five patients are included (four females, one male, aged 56±16 years). Mean cough duration was 2.6±3.5 years. All patients were on acid suppressive medications for existing gastroesophageal reflux disease (GERD) prior to referral. All lesions were identified at the mid-membranous vocal folds and morphologically encompassed a wound healing spectrum between ulceration and/or granulation tissue (granuloma) formation. Patients were treated in an interdisciplinary fashion with behavioral cough suppression therapy, superior laryngeal nerve block, and neuromodulators. Three had persistent lesions requiring procedural intervention (one office-based steroid injection and two surgical excisions). At the completion of treatment, all five patients had improvement in Cough Severity Index with an average decrease of 15.2±4.8. All but one patient had improvement in their Voice Handicap Index-10 with an average decrease of 13.2±11.1. One patient undergoing surgical intervention was noted to have a persistent lesion on follow-up. CONCLUSION Mid-membranous vocal fold lesions in patients with chronic cough are uncommon. When they do occur, they represent epithelial change arising in context of shear injury and are distinct from phonotraumatic lesions in the lamina propria. An interdisciplinary approach including behavioral cough suppression therapy, neuromodulators, superior laryngeal nerve block, and acid suppression are reasonable for initial management, reserving surgical intervention for refractory lesions once the inciting source of injury has been controlled.

VHI-10 Scores in a Treatment-Seeking Population With Dysphonia. J Voice 2023; 37:290.e1-290.e6. [PMID: 33451893 DOI: 10.1016/j.jvoice.2020.12.017] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/01/2020] [Revised: 12/02/2020] [Accepted: 12/14/2020] [Indexed: 11/30/2022]
Abstract
INTRODUCTION The VHI-10 is a patient-reported outcome measure used to record the patient's perception of impairment or handicap due to a voice problem. Scores above 11 are abnormal and indicate voice handicap. Amongst a treatment-seeking population in a large tertiary voice center, scores below the VHI-10 cutoff score of 11 were frequently noted. The aim of this study was to examine the number of people seeking voice therapy for dysphonia who scored below the established VHI-10 cutoff score. METHODS A retrospective chart review was completed of all patients attending a voice evaluation with a speech-language pathologist by referral of a laryngologist between February 1, 2017 and February 28, 2018. Patients aged 18+ years with a primary diagnosis of dysphonia were included. Sex, age, primary diagnosis, and VHI-10 score were recorded. Patients were categorized as scoring above or below the cutoff score of 11. Logistic regression was performed to determine the variables that predicted scoring below the VHI-10 cutoff. RESULTS A total of 225 patients were included. There were 91 males (40.4%) and 134 females (59.6%). Sixty-one patients (27.1%) scored below the VHI-10 cutoff of 11 at their evaluation. Younger age and male sex were predictive of scoring below the VHI-10 cutoff score. Diagnosis was not predictive of scoring above or below the cutoff score. CONCLUSION A notable proportion of treatment-seeking patients scored below the VHI-10 cutoff of 11. If treatment-seeking behavior is related to patient perception of voice handicap, one would expect fewer patients to score below the cutoff. Possible explanations might include that the VHI-10 did not sufficiently capture patient perception of handicap in the study population or the published cutoff score may be too high. Alternatively, another motivator besides handicap may have spurred treatment-seeking behavior. Given these findings, additional or alternative patient-reported outcome measures may be useful in developing a complete clinical picture regarding voice handicap.

Abstract
OBJECTIVE Patients with unilateral vocal fold paralysis commonly report dysphonia and dysphagia. Dyspnea also occurs, with studies on treatment-related change producing mixed results. Studies including patient-reported outcomes have focused on single-question global scales. The Dyspnea Index (DI) includes 10 questions, is specific to upper airway-related dyspnea, and may better capture these patients' symptoms. We evaluated change in DI after treatment. STUDY DESIGN Retrospective review. SETTING Academic medical center. METHODS Forty-three patients with unilateral vocal fold paralysis underwent injection augmentation (n = 25) or framework surgery (n = 18). DI was recorded preprocedure, 2 to 4 weeks afterward, and at approximately 3 months afterward in 19 patients. Voice Handicap Index-10, Glottal Function Index, Cough Severity Index, and Eating Assessment Tool-10 were also recorded. Change in parameters and correlations were assessed. Obesity, cardiac disease, pulmonary disease, and procedure (injection vs framework surgery) were evaluated for effect on DI. RESULTS Twenty-four patients had an abnormal baseline DI (>10). DI decreased from 14.9 ± 13.8 to 6.5 ± 9.3 after treatment (P < .001; 95% CI, 4.7-12.1). Twenty-eight scores decreased, 9 remained unchanged, and 6 increased. Change in DI was influenced by the presence of cardiac disease. Decreased DI persisted at 3-month follow-up. Voice Handicap Index-10, Glottal Function Index, Cough Severity Index, and Eating Assessment Tool-10 scores decreased and were correlated with change in DI. CONCLUSION Upper airway-related dyspnea is common in unilateral vocal fold paralysis, occurring in half of this cohort. Correcting glottic insufficiency may alleviate symptoms. Treatment decision making should consider postprocedural change in dyspnea, especially in patients for whom dyspnea is a motivating factor for seeking treatment.

Linguistic Relevance and Applicability of the Spanish VHI-10 in a Population Outside Spain. Folia Phoniatr Logop 2021; 74:223-229. [PMID: 34749357 DOI: 10.1159/000520737] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2020] [Accepted: 11/03/2021] [Indexed: 11/19/2022] Open
Abstract
INTRODUCTION The Voice Handicap Index 10 (VHI-10) has been translated to many languages. There are substantial differences between the translation methods. Translated questionnaires without appropriate linguistic validation may not capture cultural differences or be understood by the participants in the manner intended by the original developers. This also holds true between dialects within a language. There are two versions of the VHI-10 in Spanish, both translated in Spain. Considering the cultural and dialectical differences amongst Spanish speakers, it is hypothesized that these translations may not be applicable globally. The purpose of this study was to determine the linguistic relevance and applicability of the currently available versions of the VHI-10 in Spanish amongst Spanish speakers outside of Spain. METHODS This study used mixed methods qualitative and quantitative procedures consisting of semi-structured interviews and quantitative analysis of data. Sixty-nine participants met the inclusion criteria. Participants with and without a diagnosis of dysphonia were included. Demographic data collected included age, gender, cultural/dialectical background, level of education, and number of years residing in Southern California. Participants were provided the currently available translated versions of the VHI-10 in Spanish (V1 and V2). After reading both questionnaires, a semi-structured interview was conducted by a bilingual SLP. Semi-structured interview responses were coded to determine patterns of words marked as problematic/not understood or non-representative of the Spanish dialect spoken by the participants. RESULTS The majority of participants marked at least one word in both versions as problematic/not understood or non-representative of the Spanish dialect spoken (60/69, 87.0% for V1 and 63/69, 92.3%, for V2). The two words most frequently marked as problematic/not understood or non-representative of the Spanish dialect spoken were "hándicap" (marked by 51/69 participants, 73.9%) and "minusvalía" (marked by 52/69 participants, 75.4%). CONCLUSIONS Data analysis demonstrates that the majority of participants marked words as not understood/non-representative of their dialect on either V1 or V2. One question not understood or not answered could have an impact on how we interpret this PRO measure in clinical practice. Use of currently available Spanish translations of the VHI-10 may yield unreliable results when used amongst Spanish speakers outside Spain due to dialectal and cultural differences. Future work will include validation of a voice patient-reported outcome (PRO) measure that is culturally and linguistically appropriate for Spanish speakers outside Spain.

Abstract
OBJECTIVE To compare flexible distal-chip laryngoscopy (FDL) and rigid telescopic laryngoscopy (RTL) in image quality and diagnostic ability. STUDY DESIGN Prospective cohort study; blinded comparison. METHODS Eighteen normal adult subjects were recruited to undergo both FDL and RTL and normalized videos were recorded. Three blinded laryngologists compared the videos for color fidelity, illumination, resolution, and vascularity, and indicated superiority with FDL, RTL, or no difference. Raters also reported if an abnormality was seen and in which video it was better visualized. Videos for two subjects were repeated to assess intra-rater reliability, making 20 video comparisons across 3 raters for a total of 60 ratings. Differences in responses were analyzed via Mann-Whitney U and Pearson Χ2. Inter-rater reliability was assessed via Fleiss' kappa, and intra-rater reliability was assessed via percent agreement. RESULTS RTL was rated superior in all categories of image quality (47 vs 5 vs 8, P < 0.01; 47 vs 7 vs 6, P < 0.01; 51 vs 5 vs 4, P<0.01; 44 vs 9 vs 7, P < 0.01, respectively). An abnormality was seen 33 times with both modalities and 6 times with RTL only. When seen with both modalities, visualization was superior in RTL compared with FDL (29 vs 4, P <0.01). CONCLUSIONS There was significant superiority of RTL in all categories of image quality, with slight inter-rater agreement for color fidelity, resolution, and vascularity. RTL was also significantly better for visualization of abnormalities. These findings suggest superior image quality in RTL compared with FDL, but further research is required to determine if this difference is clinically significant.

Phonation Resistance Training Exercises (PhoRTE) With and Without Expiratory Muscle Strength Training (EMST) For Patients With Presbyphonia: A Noninferiority Randomized Clinical Trial. J Voice 2021; 37:398-409. [PMID: 33741235 DOI: 10.1016/j.jvoice.2021.02.015] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2020] [Revised: 02/10/2021] [Accepted: 02/11/2021] [Indexed: 10/21/2022]
Abstract
OBJECTIVES Presbyphonia negatively impacts quality of life in patients with age-related voice changes. A proof-of-concept study showed promise for high vocal intensity exercise to treat presbyphonia, which became the basis for a novel intervention for age-related voice changes known as Phonation Resistance Training Exercises (PhoRTE). Expiratory Muscle Strength Training (EMST) has also been proposed as an additional intervention to target and strengthen the aging respiratory system; however, EMST has undergone limited evaluation as an adjunct treatment for elderly patients undergoing voice therapy for presbyphonia. This study determined if the addition of EMST to PhoRTE voice therapy (PhoRTE + EMST) is at least as effective at voice improvement as PhoRTE alone. STUDY DESIGN Prospective, randomized, controlled, single-blinded, non-inferiority. MATERIALS AND METHODS Participants aged 55 years or older with a diagnosis of vocal fold atrophy were randomized to complete PhoRTE therapy or PhoRTE + EMST. The primary outcome was change in Voice Handicap Index-10 (VHI-10). Secondary outcomes included the Aging Voice Index, maximum expiratory pressure, and acoustic and aerodynamic measures of voice. Repeated measures linear mixed models were constructed to analyze outcomes at a significance level of α = 0.10. RESULTS Twenty-six participants were recruited for the study, and 24 participants were randomized to either treatment arm. Sixteen participants completed the entire study. Both treatment arms showed statistically significant and clinically meaningful improvements in VHI-10 (PhoRTE mean [M] = -8.20, P < 0.001; PhoRTE + EMST M = -9.58, P < 0.001), and PhoRTE + EMST was noninferior to PhoRTE alone (P = 0.069). Both groups experienced a statistically significant pre-post treatment decrease (improvement) in AVI scores (PhoRTE M = -18.40, P = 0.004; PhoRTE + EMST M = -16.28, P = 0.005). PhoRTE+EMST had statistically significantly greater changes in maximum expiratory pressure compared to PhoRTE alone (PhoRTE M = 8.24 cm H2O, PhoRTE + EMST M = 32.63 cm H2O; P= 0.015). Some secondary acoustic and aerodynamic outcomes displayed trends toward improvement. CONCLUSION This study demonstrates that voice therapy targeting high vocal intensity exercise (eg, PhoRTE) and EMST can play a role in improving voice outcomes for patients with presbyphonia.

Abstract
Importance One-third of singers and vocal professionals report experiencing a benefit from empirical vitamin B12 injections for improvement of mild singing-related symptoms (eg, reduced stamina, vocal fatigue, and effort). However, there is no objective evidence to support or refute these claims. Objective To assess the presence and magnitude of the effect of empirical vitamin B12 injection on the vocal performance of singers. Design, Setting, and Participants A randomized, double-blind, placebo-controlled, crossover trial was conducted from November 7, 2017, to November 30, 2018, at an academic voice center among 20 active adult singers without dysphonia but with mild vocal symptoms. Individuals with known or suspected vitamin B12 deficiency or active or recent vitamin B12 treatment were excluded. Analysis was on a per-protocol basis. Interventions Participants were randomized to receive an intramuscular (deltoid) injection of either vitamin B12 (1000 μg of cyanocobalmin) or placebo (0.9% sodium chloride). After a washout period of at least 4 weeks, participants were crossed over to receive the opposite injection. Both the investigators and participants were blinded to the order of injections. Main Outcomes and Measures The participants completed the Singing Voice Handicap Index-10 (SVHI-10), the Voice Fatigue Index (VFI), and the Evaluation of the Ability to Sing Easily (EASE) before each injection and at intervals of 1 hour, 3 hours, 24 hours, 72 hours, and 1 week after the injection. The primary time point assessment was 72 hours after injection, and the SVHI-10 score was the primary outcome measure. Results Twenty singers (10 men; median age, 22 years [range, 19-42 years]) were enrolled. The improvements after either placebo or vitamin B12 injections were comparable to each other. At 72 hours after the vitamin B12 injection, the median difference in the SVHI-10 score was 1 (95% CI, -1 to 2) compared with 3 (95% CI, 0-4) after placebo. The median difference between differences at 72 hours between placebo and vitamin B12 injections were 1.5 (95% CI, -2 to 5) for the SVHI-10, 1 (95% CI, -9 to 9) for the VFI, and -1 (95% CI, -3 to 2) for the EASE. The improvements after both injections failed to reach the estimated minimal clinically important difference. Of the 20 participants, 4 (20%) reached the estimated minimal clinically important difference in their SVHI-10 score after 72 hours for both vitamin B12 and placebo injections. Conclusions and Relevance This randomized, double-blind, placebo-controlled, crossover trial found that after empirical vitamin B12 injection to improve mild voice-related symptoms, the improvement in self-reported voice measures in singers shows no meaningful difference compared with placebo. Trial Registration ClinicalTrials.gov Identifier: NCT03437824.

Abstract
Meta-therapy refers to the clinical dialogue via which direct and indirect voice treatments are introduced and discussed, and which helps build a useful conceptual framework for voice therapy. Meta-therapy was idiosyncratically defined in previous work. However, the current colloquial narrative of meta-therapy is not standardized or specific enough to be reliably taught, rigorously studied, or clinically delivered with high fidelity. Therefore, this article uses a standard framework (the Rehabilitation Treatment Specification System or RTSS) to further articulate and operationalize meta-therapy in vocal rehabilitation. Meta-therapy's conceptual framework generally aligns with the RTSS's treatment theory and associated concepts; e.g., the treatment component and its underlying ingredients, mechanisms of action, and target. Because the treatment theories in meta-therapy most frequently involve mechanisms of action related to information processing, they primarily map onto the RTSS's Representations treatment components. The treatment targets in meta-therapy are often focused on changes in the patient's cognitions, knowledge, beliefs, attitudes, intentions, and/or awareness regarding voice-related modifications. The ingredients in meta-therapy are frequently clinician actions conveying information with the goal of appropriately shaping the patient's mental representations, and are delivered with verbal cues, stories, analogies, etc. This manuscript provides specific examples of how meta-therapy is applied in clinical voice practice. Considerations for future investigation of meta-therapy are proposed.

Pilot Evaluation of Community-Based Vocal Health Screenings. J Voice 2020; 35:666.e1-666.e5. [PMID: 32007316 DOI: 10.1016/j.jvoice.2019.12.018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2019] [Revised: 12/20/2019] [Accepted: 12/20/2019] [Indexed: 11/30/2022]
Abstract
INTRODUCTION Community-based health fairs can help identify at-risk populations, improve health literacy, and facilitate access to medical services. No community-based screenings specifically targeting vocal health were identified in the literature. The purpose of this study is to compare the results of community-based vocal health screenings across two populations: a group of community members with unknown risk of voice problems, and a group of actors belonging to a profession with a known increased risk of voice problems. METHODS Vocal health screenings were conducted at two free, community-based health fair events in the Los Angeles area. One was open to the public, and one was organized specifically for actors who are members of the Screen Actors Guild-American Federation of Television and Radio Artists. A total of 142 community members (94 nonactors and 48 actors) were administered a questionnaire on current vocal health and voice-related quality of life indices (Vocal Handicap Index-10, Vocal Fatigue Index), followed by review and discussion with a laryngologist or a speech pathologist trained in assessment and treatment of voice disorders. RESULTS A significantly higher percentage of actors (55.1%) reported current voice problems than nonactors (33.0%; χ2 = 7.122, df = 1, P = 0.008). Additionally, as measured by the Vocal Fatigue Index 2 subscale, actors reported a greater amount of perceived pain with phonation than the nonactors. Despite over half of the actors reporting current voice concerns, only 7% reported having sought medical advice regarding these concerns. CONCLUSIONS The results of this study suggest that vocal health screenings can help identify persons with voice complaints. However, in order to determine if vocal health screenings help close prevalence-presentation gap and are useful to both medical professionals and participants, more research is needed.

Abstract
Importance Aging adults face unique barriers to care and have unique health care needs with a high prevalence of chronic conditions. A high proportion of individuals in this group have voice disorders, in part due to age-related changes in laryngeal anatomy and physiologic features. These disorders contribute significantly to health care costs and remain poorly understood. Objective To describe sociodemographic characteristics and response to treatment among aging adults with voice disorders. Design, Setting, and Participants A cross-sectional study using the 2012 National Health Interview Survey was used to evaluate adults who reported voice disorders in the past 12 months. Self-reported demographics and data regarding health care visits for voice disorders were analyzed. Statistical analysis was conducted from March 1, 2017, to February 1, 2018. Main Outcomes and Measures Self-reported voice disorders, whether or not treatment was sought, which types of professionals were seen for treatment, and whether or not the voice disorder improved after treatment. Results Among 41.7 million adults in the United States 65 years or older, 4.20 million (10.1%; 2 683 199 women and 1 514 909 men; mean [SE] age, 74.5 [0.3] years) reported having voice disorders. Of those with voice disorders, 10.0% (95% CI, 8.3%-11.7%) sought treatment. Of individuals seeking treatment, 22.1% (95% CI, 7.9%-36.3%) saw an otolaryngologist and 24.3% (95% CI, 10.6%-38.0%) saw a speech language pathologist. By controlling for race/ethnicity, income, sex, and geography, it was found that men were less likely than women to report voice disorders (36.1% [95% CI, 31.7%-40.5%] vs 63.9% [95% CI, 59.5%-68.3%]; odds ratio, 0.70; 95% CI, 0.57-0.86). Race/ethnicity, income, and geography were not significantly associated with the likelihood that an individual 65 years or older reported voice disorders. A greater percentage of elderly adults seeking treatment than not seeking treatment reported improvement in symptoms (32.4%; 95% CI, 17.9%-47.0% vs 15.6%; 95% CI, 10.4%-20.8%). Among adults treated for a voice disorder, a lower proportion of adults 65 years or older reported improvement in symptoms with treatment compared with adults younger than 65 years (32.4%; 95% CI, 17.9%-47.0% vs 56.0%; 95% CI, 42.5%-69.6%). Conclusions and Relevance A small percentage of older adults with voice disorders seek treatment; even fewer are treated by an otolaryngologist or a speech language pathologist. A greater percentage of those who undergo treatment experienced symptomatic improvement compared with those who did not undergo treatment. These trends highlight the need for greater access to and awareness of services available to older adults with voice disorders.

Abstract
Importance Problems with speech in patients with facial paralysis are frequently noted by both clinicians and the patients themselves, but limited research exists describing how facial paralysis affects verbal communication. Objective To assess the influence of facial paralysis on communicative participation. Design, Setting, and Participants A nationwide online survey of 160 adults with unilateral facial paralysis was conducted from March 1 to June 1, 2017. To assess communicative participation, respondents completed the Communicative Participation Item Bank (CPIB) Short Form questionnaire and the Facial Clinimetric Evaluation (FaCE) Scale. Main Outcomes and Measures The CPIB Short Form and the correlation between the CPIB Short Form and FaCE Scale. In the CPIB, the level of interference in communication is rated on a 4-point Likert scale (where not at all = 3, a little = 2, quite a bit = 1, and very much = 0). Total scores for the 10 items range from 0 (worst) to 30 (best). The FaCE Scale is a 15-item instrument that produces an overall score ranging from 0 (worst) to 100 (best), with higher scores representing better function and higher quality of life. Results Of the 160 respondents, 145 (90.6%) were women and 15 were men (mean [SD] age, 45.1 [12.6] years). Most respondents reported having facial paralysis for more than 3 years. Causes of facial paralysis included Bell palsy (86 [53.8%]), tumor (41 [25.6%]), and other causes (33 [20.6%]), including infection, trauma, congenital defects, and surgical complications. The mean (SD) score on the CPIB Short Form was 0.16 (0.88) logits (range, -2.58 to 2.10 logits). The mean (SD) score of the FaCE Scale was 40.92 (16.05) (range, 0-83.3). Significant correlations were observed between the CPIB Short Form and overall FaCE Scale scores, as well as the Social Function, Oral Function, Facial Comfort, and Eye Comfort subdomains of the FaCE Scale, but not with the Facial Movement subdomain. Conclusions and Relevance Patients with facial paralysis in this study sample reported restrictions in communicative participation that were comparable with restrictions experienced by patients with other known communicative disorders, such as laryngectomy and head and neck cancer. We believe that communicative participation represents a unique domain of dysfunction and can help quantify the outcome of facial paralysis and provide an additional frame of reference when assessing treatment outcomes.

Vocal Dose in Older Adults with Presbyphonia: An Analytic, Cross-Sectional Study. J Voice 2018; 34:221-230.

Abstract
PURPOSE Older patients with age-related voice changes (presbyphonia) are considered vocal under-doers due to a reportedly low a amount and intensity of voice use (ie, low vocal dose). This low voice use may be consequential to negative effects of presbyphonia like throat discomfort, as well as anxiety and frustration from difficulty communicating. Causally speaking, vocal fold atrophy (presbylaryngis) may indicate inadequate intrinsic laryngeal muscle loading with low voice use, though research is lacking. As a first step, this study examined voice use objectively using vocal dosimetry in older adults with presbyphonia. We hypothesized participants, especially if retired, would exhibit low vocal doses, and lower than reported for other populations. METHOD This research used an analytic, cross-sectional design with subgroup analyses to determine feasibility of vocal dosimetry in older adults with presbyphonia. Thirteen older adults with presbyphonia (7 males) completed vocal dose monitoring using an ambulatory phonation monitor (APM). The APM measured vocal parameters over a day of monitoring, from which time, cycle, and distance doses were calculated. Data also were gathered on demographics, vocal handicap, and vocal effort. RESULTS Descriptively, the group showed a low mean time dose as compared to published vocal dose data from other populations. Females exhibited significantly higher mean values of time dose, cycle dose, and fundamental frequency than males. Time dose for males was negatively correlated with vocal effort. Subgroup analyses failed to detect an effect of age group, but found significantly a higher mean value for time dose in employed, compared to retired, participants. CONCLUSIONS Consistent with self-report, we found older adults with presbyphonia exhibit low time doses, which were in contrast to high vocal doses published on teachers, patients with dysphonia, and even office workers. We found differences in vocal dose as a function of sex and employment status. Though a limited sample, findings suggest patients with presbyphonia may demonstrate low vocal dose, which may be a useful target in treatment.

Abstract
OBJECTIVES To establish the validity of the OMNI Vocal Effort Scale (OMNI-VES) for resistance exercise, a single-question pictorial scale, in voice-related perceived exertion. Additionally, the study aimed to assess the role of the OMNI-VES as an outcome measurement in the treatment of adductor spasmodic dysphonia (ADSD). METHODS A prospective validation study was conducted on 226 participants. The case group was comprised of 178 patients receiving botulinum toxin (BTX) injections for ADSD and 48 controls without a voice disorder. Prior to a planned injection, the participants were asked to complete the OMNI-VES and the Voice-Related Quality-of-Life (V-RQOL) questionnaires, and the clinician completed the Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V). A subgroup of 17 patients were administered a repeat assessment 1 month after injection. RESULTS There was a weak correlation between the OMNI-VES and the V-RQOL score (Tau-b = -0.252, P < 0.001), and no significant correlation with the CAPE-V. Participants with ADSD had significantly higher OMNI-VES scores compared with normal controls, 5.07 ± 2.18 and 1.47 ± 2.28, respectively (P value < 0.0001). The average OMNI-VES score significantly improved 1 month following a BTX injection, from 6 ± 2.4 to 3.4 ± 2.8 (P value = 0.0003). Eighty-eight percent of the patients demonstrated a decrease in the OMNI-VES score following injection, whereas only 47% demonstrated an improvement in the V-RQOL score. CONCLUSION The OMNI-VES is a validated tool for rating perceived voice-related exertion in people with ADSD and can be used for evaluating response to BTX injection treatment.

Abstract
INTRODUCTION There is a belief among vocalists that there are voice benefits from vitamin B12 treatment. Yet there are no previous reports regarding vitamin B12 effects on voice. OBJECTIVES To assess the prevalence of vitamin B12 use among singers and their beliefs regarding vitamin B12 therapy. METHODS Anonymous online survey administered to singers, singing-teachers, speech-language pathologists, and laryngologists. RESULTS A total of 192 participants completed the surveys; 128 singers (68 singing-teachers, 30 speech-language pathologists) and 64 laryngologists. Among singers, 12% have perceived voice benefits from vitamin B12 treatment taken for any reason. Four percent used vitamin B12 for voice benefits; all perceived voice benefits as a result. The leading voice benefits were improved stamina, reduced effort, confidence, and control. Nineteen percent of the singers would recommend vitamin B12 treatment to a friend; 15% of the singing-teachers would recommend it to a student. Among laryngologists, 33% been asked by a singer to prescribe vitamin B12 for voice benefits; 9% have prescribed it in the past. Yet only 3% would you recommend it to a patient. When asked "Do you believe vitamin B12 therapy improves vocal performance?" 31% of the singers responded "Yes," compared with none in the laryngologists. When asked "Do you think the singing community believes vitamin B12 therapy improves vocal performance?" 26% of the singers responded "Yes," compared with 53% of the laryngologists (P = 0.0002). CONCLUSIONS There is a discrepancy between the singers' and the laryngologists' beliefs regarding vocal benefits perceived by vitamin B12. Blinded randomized trials are required to verify or refute this belief.

Abstract
INTRODUCTION Catastrophization is a cognitive distortion that has been studied in pain patients and found to be a significant factor in their disability and response to treatment. Dysphonia patients may demonstrate a similar behavior, suggesting the existence of voice catastrophization. OBJECTIVE To establish the validity of the Voice Catastrophization Index (VCI), a new instrument estimating voice symptoms catastrophization. METHODS A prospective study. Patients with and without voice conditions were administered with the VCI, Voice-Related Quality of Life (V-RQOL), and the Generalized Anxiety Disorder-7 (GAD-7)questionnaires. Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V) rating was determined for patients with voice conditions. RESULTS Ninety-one patients participated, 65 with voice conditions and 26 without. 61.5% were females; mean age was 49.8 ± 15.7 years. The VCI score for patients with voice conditions was significantly higher, 22.46 ± 16.56, compared with 3.96 ± 10.79, respectively (P value < 0.0001). The VCI demonstrated moderate correlation with both V-RQOL and GAD-7 scores: -0.562 and 0.560, respectively (P value < 0.000001); however, it showed no correlation with the CAPE-V. The VCI's internal consistency with each of its three dimensions and 13 items was acceptable to strong. The reproducibility and stability was demonstrated in a subgroup of 26 patients; 81% of these patients had a difference of 10 or less points between the two evaluations. CONCLUSIONS The VCI accomplished the requirements of a scale's validity for estimation of voice symptoms catastrophization in voice patients. The potential role of voice catastrophization as a predictor of treatment response and tailoring can now be investigated using the VCI.

Abstract
OBJECTIVE The aim of this study was to describe the presentation of pharyngeal dystonia (PD), which can occur as a focal or segmental dystonia with a primarily pharyngeal involvement for the discussion of treatment methods for controlling consequent symptoms. PD is specific to speech-related tasks. METHODS A retrospective medical record review of four patients with PD was performed. RESULTS All patients were initially misdiagnosed with adductor spasmodic dysphonia and failed standard treatment with botulinum toxin type A (BTX). On laryngoscopy, the patients were discovered to have segmental or focal dystonia primarily affecting the pharyngeal musculature contributing to their vocal manifestations. A novel treatment regimen was designed, which involved directing BTX injections into the muscles involved in spasmodic valving at the oropharyngeal level. After titrating to an optimal dose, all patients showed improvement in their voice and speech with only mild dysphagia. These patients have maintained favorable results with repeat injections at 6- to 12-week intervals. CONCLUSIONS PD, or dystonia with predominant pharyngeal involvement, is a rare entity with vocal manifestations that are not well described. It can be easily mistaken for spasmodic dysphonia. PD is specific to speech-related tasks. A novel method of BTX injections into the involved muscles results in a significant improvement in voice without significant dysphagia.

Abstract
OBJECTIVE A recently published retrospective chart review of aerodynamic profiles of women with primary muscle tension dysphonia by Gillespie et al (2013) identified various relationships between mean airflow rate (MFR) and estimated subglottal pressure (est-Psub). The current retrospective study expanded the diagnostic categories to include all voice disorders referred for voice therapy. Three research questions were proposed: (1) Are there differences in the MFR and the est-Psub compared with the normal control group? (2) Within the disordered population, are there different variations in the pairing of MFR and est-Psub? (3) If these variations exist, are they diagnosis specific? METHODS A retrospective chart review of patients seen for acoustic and aerodynamic voice assessment at the Emory Voice Center between January 1, 2013 and December 31, 2014, were examined for aerodynamic measures of est-Psub and MFR; of these, 192 met the inclusion criteria. Simple t test, two-step cluster analysis, and analysis of variance, as well as Tukey multiple comparisons, were performed using R and SPSS. RESULTS Mean est-Psub was significantly greater in the group with voice disorder than in the control group (P value < 0.001). However, no statistical significance was found when comparing the MFR with the control group (P value <0.59). Nine possible pairings of MFR and est-Psub were found. Sufficient evidence was not found to detect significant differences in these pairings across diagnostic groups. CONCLUSION With regard to the rate and interrelationships of MFR and est-Psub, the findings of this study are similar to those of Gillespie et al, that is, MFR and est-Psub are not determinate of diagnosis.

Abstract
OBJECTIVES/HYPOTHESIS To assess the comparative effectiveness of botulinum toxin and propranolol in patients with essential vocal tremor (EVT). STUDY DESIGN Individual prospective cohort study. METHODS Study patients were recruited at the Emory Voice Center from patients seeking treatment for EVT. Exclusion criteria included current β-blocker treatment, spasmodic dysphonia, or other disease that prevented the use of propranolol therapy. A 10-week washout period from prior botulinum toxin treatment occurred before enrollment. Patients were assessed via the Voice-Related Quality-Of-Life (VRQOL) questionnaire, Quality of life in Essential Tremor questionnaire, and blinded perceptual voice assessment. These assessments were made at baseline voice 2 weeks after propranolol therapy and 4 weeks after botulinum toxin injection. RESULTS Eighteen patients were enrolled. After 2 to 4 weeks of propranolol therapy (with a maximum dosage of 60 mg to 90 mg per day), patients report an average ΔVRQOL of 9.31. Six patients report significant VRQOL improvement >10, with the rest reporting changes between -7.5 and 7.5. Fifteen patients were followed for at least 4 weeks after botulinum toxin injection, reporting an average improvement in scaled VRQOL of 22.00. Blinded perceptual voice assessment demonstrates an improvement in overall severity of tremor with botulinum toxin. CONCLUSIONS In some patients with EVT, propranolol led to significant vocal improvement with no major side effects. Although botulinum toxin remains the gold-standard therapy for patients with EVT, propranolol represents a possible alternative or adjuvant therapy for certain patients.

Abstract
IMPORTANCE Spasmodic dysphonia (SD) can be difficult to diagnose, and patients often see multiple physicians for many years before diagnosis. Improving the speed of diagnosis for individuals with SD may decrease the time to treatment and improve patient quality of life more quickly. OBJECTIVE To assess whether the diagnosis of SD can be accurately predicted through auditory cues alone without the assistance of visual cues offered by laryngoscopic examination. DESIGN, SETTING, AND PARTICIPANTS Single-masked, case-control study at a specialized referral center that included patients who underwent laryngoscopic examination as part of a multidisciplinary workup for dysphonia. Twenty-two patients were selected in total: 10 with SD, 5 with vocal tremor, and 7 controls without SD or vocal tremor. INTERVENTIONS The laryngoscopic examination was recorded, deidentified, and edited to make 3 media clips for each patient: video alone, audio alone, and combined video and audio. These clips were randomized and presented to 3 fellowship-trained laryngologist raters (A.D.R., A.T.H., and A.M.K.), who established the most probable diagnosis for each clip. Intrarater and interrater reliability were evaluated using repeat clips incorporated in the presentations. MAIN OUTCOMES AND MEASURES We measured diagnostic accuracy for video-only, audio-only, and combined multimedia clips. These measures were established before data collection. Data analysis was accomplished with analysis of variance and Tukey honestly significant differences. RESULTS Of patients with SD, diagnostic accuracy was 10%, 73%, and 73% for video-only, audio-only, and combined, respectively (P < .001, df = 2). Of patients with vocal tremor, diagnostic accuracy was 93%, 73%, and 100% for video-only, audio-only, and combined, respectively (P = .05, df = 2). Of the controls, diagnostic accuracy was 81%, 19%, and 62% for video-only, audio-only, and combined, respectively (P < .001, df = 2). CONCLUSIONS AND RELEVANCE The diagnosis of SD during examination is based primarily on auditory cues. Viewing combined audio and video clips afforded no change in diagnostic accuracy compared with audio alone. Laryngoscopy serves an important role in the diagnosis of SD by excluding other pathologic causes and identifying vocal tremor.

How long does it take to diagnose cervical dystonia? J Neurol Sci 2013; 335:72-4. [PMID: 24034410 DOI: 10.1016/j.jns.2013.08.028] [Citation(s) in RCA: 20] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2013] [Revised: 08/19/2013] [Accepted: 08/20/2013] [Indexed: 12/27/2022]
Abstract
BACKGROUND Dystonia is a neurological disorder characterized by involuntary twisting movements and postures. The neck is among the most commonly affected regions, and diagnosis can be made readily through a simple clinical evaluation. The goal of this study was to explore how long it took patients to receive a diagnosis of cervical dystonia after symptom onset. METHODS A structured questionnaire was administered at outpatient clinics of a tertiary care academic medical center to 146 consecutively evaluated patients. The questionnaire addressed the length of time from symptom onset to diagnosis, the numbers and types of providers seen before reaching a diagnosis, and treatments attempted prior to receiving botulinum toxin. RESULTS A total of 108 patients saw a mean of 3.5 providers over a mean period of 44 months from symptom onset to diagnosis. For patients with symptom onset in the last decade only, patients saw a mean of 3.0 providers over a mean of 14 months. CONCLUSIONS Although cervical dystonia is the most common form of dystonia with clinical features readily identifiable by a simple history and examination, patients typically see multiple providers over more than a year before reaching a diagnosis and receiving optimal therapy. Improved awareness of the clinical features will enable patients to obtain appropriate therapy more rapidly.

Abstract
Objectives: We evaluated the voice and vocal fold pliability outcomes of European Laryngological Society (ELS) deep type I (subepithelial) and type II (subligamentous) cordectomies for early glottic cancer. Methods: We reviewed the medical records of patients with glottic carcinoma at a tertiary care medical center between 2005 and 2011. Their procedures were stratified into ELS type I and ELS type II cordectomies. The data recorded included age, gender, tumor stage, recurrence, patient-assessed voice-related quality of life, perceptual voice evaluation, and stroboscopy. Results: Four patients were identified as having subepithelial cordectomy, and 13 as having subligamentous cordectomy. The average preoperative and postoperative voice-related quality of life scores were 65 and 74 for the ELS I cohort and 64 and 95 for the ELS II group. The preoperative and postoperative perceptual voice evaluation scores were 56 and 35 for the ELS I cohort and 45 and 21 for the ELS II cohort. The ELS I cohort had a moderately to severely reduced mucosal wave, with 75% of patients demonstrating glottic insufficiency, whereas the ELS II cohort had a mildly to moderately reduced mucosal wave, with 8% of patients demonstrating glottic insufficiency. The survival outcomes were the same. Conclusions: Patients who underwent subligamentous excision of early glottic cancer had significantly improved postoperative voice and stroboscopy scores. This finding suggests that if tumor resection reaches the vocal ligament, and minimal superficial lamina propria can be preserved, subligamentous cordectomy should be performed.

Abstract
Objective: This study measured the baseline knowledge of NASCAR fans regarding the risks, signs, and symptoms of head and neck cancer and examined the effectiveness of education efforts concerning head and neck cancer during a free, community-based head and neck cancer screening. Method: Adults touring the midway during a NASCAR race were recruited for the study. A survey regarding knowledge on head and neck cancer (HNCA) was administered before and after HNCA screening which included education on risks, signs, and symptoms of such malignancies. Participants were surveyed again 3 months after the race. Results: Four hundred seventy-eight NASCAR fans participated in the study. Of these, 34% reported being a current smoker and 10% reported being a current user of smokeless tobacco. Of the 478 participants, 106 were contacted at the 3-month follow up. A univariate ANOVA indicated knowledge of head and neck cancer changed significantly over time, F(2, 204) = 18.66, P < .001, η2 = .16. Specifically, knowledge assessed after the educational component was significantly higher than at baseline. At the 3-month follow-up, knowledge was significantly higher than baseline, but significantly lower than after exposure to the educational component. Conclusion: Participants demonstrated increased knowledge on the risks, signs, and symptoms of HNCA immediately following the educational session during the screening and at 3-month follow-up. While specific knowledge on HNCA was greater at the 3-month follow-up than baseline, it significantly diminished compared with post-screening test results, suggesting poor long-term knowledge retention.

Abstract
Objective: Compare the knowledge of the relationship between HPV and head and neck cancer (HNCA) in 3 unique populations: NASCAR race attendees, undergraduates, and medical students. Compare the self-reported level of information disseminated by healthcare providers regarding HPV and HNCA, respectively. Method: A 21-item questionnaire was administered to 490 NASCAR race attendees, 186 undergraduate students, and 158 medical students. The survey assessed their knowledge regarding the relationship between HPV and HNCA using a Likert scale. The survey also assessed the level of information disseminated by healthcare providers regarding HPV and HNCA. Results: NASCAR attendees evidenced significantly ( P < .001, η2 = .10) lower levels of knowledge of the relationship between HPV and cervical cancer than college or medical students. NASCAR attendees evidenced significantly ( P < .001, η2 = .02) lower levels of knowledge regarding relationship between HPV and HNCA than medical students or undergraduates. NASCAR attendees reported receiving significantly ( P < .001, η2 = .10) higher levels of information regarding HNCA compared to college or medical students. Undergraduates and medical students reported receiving significantly ( P < .001, η2 = .02) higher levels of information from healthcare providers about HPV than NASCAR attendees. Conclusion: Significant group differences concerning knowledge of the relationship between HPV and cervical cancer and between HPV and HNCA were detected. However, all 3 groups demonstrated higher levels of knowledge of the relationship between HPV and cervical cancer compared to HPV’s relationship with HNCA.

Abstract
OBJECTIVE Although research has documented a difference in cancer risk perception between smokers and nonsmokers, this has not been specifically documented for head and neck cancer. The aim of this study was to determine differences in risk perception for head and neck cancer between smokers and nonsmokers in an at-risk population. STUDY DESIGN A cross-sectional survey was administered. SETTING Community-based head and neck cancer screenings. SUBJECTS AND METHODS Participants completed a 28-item questionnaire assessing sociodemographic information, smoking status, and risk perception of head and neck cancer. RESULTS In total, 507 participants completed the questionnaire. Multivariate analysis of variance (MANCOVA) using dependent variables related to risk perception of head and neck cancer evidenced a significant main effect that smokers (mean [SD], 1.10 [0.07]) worried about head and neck cancer significantly more than nonsmokers (0.64 [0.06]), F(1, 459) = 26.97, P < .001, η(2) = .06, and nonsmokers (2.70 [0.05]) believed head and neck cancer was significantly more dangerous than did smokers (2.53 [0.06]), F(1, 459) = 5.90, P = .015, η(2) = .01. CONCLUSION Findings indicated differences in perception of risk for head and neck cancer between smokers and nonsmokers. By gaining a better understanding of the psychosocial factors related to perceived risk of head and neck cancer, otolaryngologists and health care providers may better tailor interventions aimed at increasing awareness of cancer risk and promoting cessation.

Coprevalence of anxiety and depression with spasmodic dysphonia: a case-control study. J Voice 2011; 26:667.e1-6. [PMID: 22209056 DOI: 10.1016/j.jvoice.2011.08.011] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2011] [Accepted: 08/18/2011] [Indexed: 11/25/2022]
Abstract
INTRODUCTION There is evidence supporting an association between depression and anxiety in patients with chronic disease. Spasmodic dysphonia (SD) is a chronic, incurable, and disabling voice disorder. Reported rates of depression and anxiety in SD range from 7.1% to 72%, with a maximum number of 18 patients. The goal of this study was to define the coprevalence of depression and anxiety with SD. MATERIALS AND METHODS A single-institution case-control study was performed from May to July 2010. Consecutive patients with SD and benign voice disorders were enrolled prospectively. On enrollment, patients were asked to fill out a questionnaire that reviewed the duration of the voice disorder and personal history of anxiety and depression, including current and lifetime diagnosis. RESULTS One hundred forty-six controls with benign voice disorders and 128 patients with SD were enrolled. Patients with SD were no more likely to be diagnosed with depression or anxiety than those of the control group (odds ratio [OR]=0.985, 95% confidence interval [CI]=0.59-1.63; and OR=1.314; 95% CI=0.75-2.3, respectively). Additionally, duration of disease was a risk factor for depression in both the SD group and the control group, and the association was not significantly different between groups. CONCLUSION Patients with SD were no more likely to have depression or anxiety than those with other voice disorders. It is important for otolaryngologists to be aware of the increased rates of depression in patients diagnosed with chronic diseases, including voice disorders, and to refer to a psychiatrist when appropriate.

Abstract
OBJECTIVES/HYPOTHESIS The aim of this study was to define the coprevalence of tremor with spasmodic dysphonia (SD). STUDY DESIGN A single-institution, prospective, case-control study was performed from May 2010 to July 2010. METHODS Consecutive patients with SD (cases) and other voice disorders (controls) were enrolled prospectively. Each participant underwent a voice evaluation and an evaluation for tremor. RESULTS There were 146 voice disorder controls and 128 patients with SD enrolled. Of patients with SD 26% had vocal tremor, 21% had nonvocal tremor. Patients with SD were 2.8 times more likely to have coprevalent tremor than the control group (odds ratio = 2.81; 95% confidence interval, 1.55-5.08), and only 35% of patients with SD had been seen by a neurologist for the evaluation of dystonia and tremor. CONCLUSIONS Tremor is highly prevalent in patients with SD. It is important for each patient diagnosed with SD to undergo an evaluation for tremor, and this is especially important in patients diagnosed with vocal tremor.

Abstract
OBJECTIVE Examine the usefulness of large-scale community-based head and neck cancer screening for reducing tobacco use in an at-risk population. Questions answered: (1) Is participating in a community-based head and neck cancer screening related to a reduction in tobacco usage? (2) Do differing factors between participants predict behavior change? STUDY DESIGN Survey based with a longitudinal follow-up component. SETTING Atlanta Motor Speedway during a National Association of Stock Car Auto Racing (NASCAR) race event. SUBJECTS AND METHODS Recruited NASCAR fans (n = 620). Initial screening and 11-question survey for 6-month telephone follow-up. RESULTS One hundred fifty-six participants (25%) required medical follow-up. Chi-square analysis indicated a significantly higher proportion of smokers (13%) evidenced positive findings compared to nonsmokers (8%) or past smokers (6%). Kruskal-Wallis analysis followed by Dunn's multiple comparison post hoc test indicated smokers were from a significantly lower socioeconomic status background compared to nonsmokers. Analysis of variance indicated contacted participants reported smoking significantly fewer cigarettes per day 6 months postscreening compared to the number of cigarettes smoked at the baseline. Forty-four (59%) participants reported reducing the number of cigarettes smoked per day, and 11 participants reported quitting smoking. CONCLUSION The authors have demonstrated that large-scale community-based head and neck cancer screenings can be effectively implemented in nonmedical venues. This study demonstrated that targeting education for reduction of risk factors in the NASCAR population positively affected tobacco cessation.

Abstract
OBJECTIVES/HYPOTHESIS Botulinum toxin (Botox) injections into the thyroarytenoid muscles are the current standard of care for adductor spasmodic dysphonia (ADSD). Reported adverse effects include a period of breathiness, throat pain, and difficulty with swallowing liquids. Here we report multiple cases of bilateral abductor paralysis following Botox injections for ADSD, a complication previously unreported. STUDY DESIGN Retrospective case series. METHODS Patients that received Botox injections for spasmodic dysphonia between January 2000 and October 2009 were evaluated. Patients with ADSD were identified. The number of treatments received and adverse effects were noted. For patients with bilateral abductor paralysis, age, sex, paralytic Botox dose, prior Botox dose, and course following paralysis were noted. RESULTS From a database of 452 patients receiving Botox, 352 patients had been diagnosed with ADSD. Of these 352 patients, eight patients suffered bilateral abductor paralysis, and two suffered this complication twice. All affected patients were females over the age of 50 years. Most patients had received treatments prior to abductor paralysis and continued receiving after paralysis. Seven patients recovered after a brief period of activity restrictions, and one underwent a tracheotomy. The incidence of abductor paralysis after Botox injection for ADSD was 0.34%. CONCLUSIONS Bilateral abductor paralysis is a rare complication of Botox injections for ADSD, causing difficulty with breathing upon exertion. The likely mechanism of paralysis is diffusion of Botox around the muscular process of the arytenoid to the posterior cricoarytenoid muscles. The paralysis is temporary, and watchful waiting with restriction of activity is the recommended management.

Clinical Practice Guideline: Hoarseness (Dysphonia). Otolaryngol Head Neck Surg 2009; 141:S1-S31. [DOI: 10.1016/j.otohns.2009.06.744] [Citation(s) in RCA: 203] [Impact Index Per Article: 13.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2009] [Accepted: 06/26/2009] [Indexed: 12/27/2022]
Abstract
Objective: This guideline provides evidence-based recommendations on managing hoarseness (dysphonia), defined as a disorder characterized by altered vocal quality, pitch, loudness, or vocal effort that impairs communication or reduces voice-related quality of life (QOL). Hoarseness affects nearly one-third of the population at some point in their lives. This guideline applies to all age groups evaluated in a setting where hoarseness would be identified or managed. It is intended for all clinicians who are likely to diagnose and manage patients with hoarseness. Purpose: The primary purpose of this guideline is to improve diagnostic accuracy for hoarseness (dysphonia), reduce inappropriate antibiotic use, reduce inappropriate steroid use, reduce inappropriate use of anti-reflux medications, reduce inappropriate use of radiographic imaging, and promote appropriate use of laryngoscopy, voice therapy, and surgery. In creating this guideline the American Academy of Otolaryngology—Head and Neck Surgery Foundation selected a panel representing the fields of neurology, speech-language pathology, professional voice teaching, family medicine, pulmonology, geriatric medicine, nursing, internal medicine, otolaryngology–head and neck surgery, pediatrics, and consumers. Results The panel made strong recommendations that 1) the clinician should not routinely prescribe antibiotics to treat hoarseness and 2) the clinician should advocate voice therapy for patients diagnosed with hoarseness that reduces voice-related QOL. The panel made recommendations that 1) the clinician should diagnose hoarseness (dysphonia) in a patient with altered voice quality, pitch, loudness, or vocal effort that impairs communication or reduces voice-related QOL; 2) the clinician should assess the patient with hoarseness by history and/or physical examination for factors that modify management, such as one or more of the following: recent surgical procedures involving the neck or affecting the recurrent laryngeal nerve, recent endotracheal intubation, radiation treatment to the neck, a history of tobacco abuse, and occupation as a singer or vocal performer; 3) the clinician should visualize the patient's larynx, or refer the patient to a clinician who can visualize the larynx, when hoarseness fails to resolve by a maximum of three months after onset, or irrespective of duration if a serious underlying cause is suspected; 4) the clinician should not obtain computed tomography or magnetic resonance imaging of the patient with a primary complaint of hoarseness prior to visualizing the larynx; 5) the clinician should not prescribe anti-reflux medications for patients with hoarseness without signs or symptoms of gastroesophageal reflux disease; 6) the clinician should not routinely prescribe oral corticosteroids to treat hoarseness; 7) the clinician should visualize the larynx before prescribing voice therapy and document/communicate the results to the speech-language pathologist; and 8) the clinician should prescribe, or refer the patient to a clinician who can prescribe, botulinum toxin injections for the treatment of hoarseness caused by adductor spasmodic dysphonia. The panel offered as options that 1) the clinician may perform laryngoscopy at any time in a patient with hoarseness, or may refer the patient to a clinician who can visualize the larynx; 2) the clinician may prescribe anti-reflux medication for patients with hoarseness and signs of chronic laryngitis; and 3) the clinician may educate/counsel patients with hoarseness about control/preventive measures. Disclaimer: This clinical practice guideline is not intended as a sole source of guidance in managing hoarseness (dysphonia). Rather, it is designed to assist clinicians by providing an evidence-based framework for decision-making strategies. The guideline is not intended to replace clinical judgment or establish a protocol for all individuals with this condition, and may not provide the only appropriate approach to diagnosing and managing this problem.

Analysis of voice change during cellular phone use: a blinded controlled study. J Voice 2009; 24:308-13.

Abstract
It is a growing belief that cellular phone use may be hazardous to the voice. This study aims to assess voice production in different conversational scenarios to identify any changes in vocal production that may be specific to cellular phone use. Twenty healthy participants were randomized to seven conversational scenarios: quiet conditions face to face; quiet conditions over a landline; quiet conditions using a cellular phone (QCP); quiet conditions using cellular phone with earpiece (QCPE); noisy conditions face to face (NFF); noisy conditions using cellular phone (NCP); and noisy conditions using cellular phone with earpiece (NCPE). In each condition, participants performed spontaneous speech, a standardized reading passage, and sustained voicing. Sound pressure levels (dB SPL) and fundamental frequencies (F(0)[Hz]) were measured. Subjects completed a 100-mm visual analog scale measuring vocal effort after each speaking scenario. Statistical analysis was performed using analysis of variance (ANOVA). There was a significant difference in dB SPL and F(0) between all quiet conditions relative to all noisy conditions (P<0.001). There was no difference in cellular phone use relative to any other conversational condition in mean dB SPL, respective of ambient noise. Vocal effort was rated greater for noisy conditions compared with quiet conditions. Cellular phone use does not lead to a significant change in voice production relative to other speaking conditions. Voice problems associated with cellular phone use may simply be a function of the increased amount of voice use and increased vocal loudness (Lombard effect) associated with speaking in noisy situations rather than a variable inherent to the phone.

Abstract
Objective To review vocal outcome measures, using the Voice Related Quality of Life (VRQOL) index, after simultaneous bilateral posterior cricoarytenoid muscle botulinum toxin injections. Study Design Case series. Setting Tertiary care academic clinic. Subjects and Methods Fourteen subjects with abductor spasmodic dysphonia received 37 simultaneous bilateral posterior cricoarytenoid muscle botulinum toxin injections for isolated abductor spasmodic dysphonia (ABSD) over a 16-month period. Main Outcome Measures VRQOL index. Results Of the 37 injections, 33 of 37 (89%) resulted in improvement. Three injections resulted in no improvement, and one injection resulted in a worse VRQOL. The overall VRQOL mean improvement was 19.8 (range 5–53), with an average pre/postinjection VRQOL interval of 36 days (range 21–45 days). CONCLUSIONS: Simultaneous bilateral posterior cricoarytenoid muscle botulinum injections result in a statistically significant improvement in VRQOL index scores for a high percentage of ABSD patients, thus improving patient quality of life.

Abstract
SUMMARY Voice therapy is a preferred treatment for many voice problems. Many patients referred to voice therapy by their otolaryngologist fail to follow through with the recommendation. Unlike other behavior change therapies, there are no studies documenting the incidence of poor patient attendance in voice therapy. The primary purpose of this study was to document initial patient adherence to the physician's recommendation for voice therapy. A retrospective review of 294 charts was conducted at 2 voice institutions in Atlanta, GA. Reviews included adherence to (1) the physician's referral to the speech-language pathologist and (2) the speech-language pathologist's recommendation for follow-up voice therapy. Thirty-eight percent of patients did not adhere to the physician's recommendation to attend voice therapy. Of those who initiated follow-through, 47% did not return after the initial speech-language pathology evaluation session. There was no significant difference in attendance by gender or by age group. The primary reasons reported for nonattendance were insurance denials, resolution of the problem, and distance to the clinic. The attendance rates described in this study were low but consistent with research published in the fields of otolaryngology, gastroenterology, and psychology. Poor patient attendance is an important area to consider in outcomes research and the cost to healthcare.

Abstract
Spasmodic dysphonia (SD) is a focal dystonia of the larynx. Adductor spasmodic dysphonia (ADSD) involves the laryngeal adductor muscles, and symptoms of vocal roughness, staccato-like sounds, and stops in phonation. Abductor spasmodic dysphonia (ABSD) affects the laryngeal abductor muscles, resulting in a breathy or whispered voice quality and voice breaks. SD has a significant impact on the quality of life. This article discusses symptoms of SD and the standard treatment of SD.

Abstract
Studies of patient adherence to health behavior programs, such as physical exercise, smoking cessation, and diet, have resulted in the formulation and validation of the Transtheoretical Model (TTM) of behavior change. Although widely accepted as a guide for the development of health behavior interventions, this model has not been applied to vocal rehabilitation. Because resolution of vocal difficulties frequently depends on a patient's ability to make changes in vocal and health behaviors, the TTM may be a useful way to conceptualize voice behavior change processes, including the patient's readiness for change. The purpose of this paper is to apply the TTM to the voice therapy process to: (1) provide an organizing framework for understanding of behavior change in voice therapy, (2) explain how treatment adherence problems can arise, and (3) provide broad strategies to improve treatment adherence. Given the significant role of treatment adherence in treatment outcome, considering readiness for behavior change should be taken into account when planning treatment. Principles of health behavior change can aid speech pathologists in such understanding and estimating readiness for voice therapy.

Abstract
The purpose of this study was to investigate the correlation between the Voice Handicap Index (VHI) and the Voice-Related Quality of Life Measure (V-RQOL), and to test conversion of scores between the two instruments. Understanding the relationship between instruments will facilitate comparison of voice outcome studies using different measures. A retrospective medical chart review of 140 consecutive patients with a chief complaint related to their voice presenting for speech pathology voice evaluation following laryngology evaluation and diagnosis was adopted. Each patient who filled out the VHI and V-RQOL within a 2-week period with no intervening treatment was included in the study. Correlation analysis for total scores was performed for the patients meeting inclusion criteria (n=132). Correlations were also performed as a function of diagnosis. Calculated VHI score based on measured V-RQOL score was compared to measured VHI score. Pearson correlation between scores on the VHI and V-RQOL was -0.82. There was no significant difference between the mean measured and mean calculated VHI scores. For individual scores, however, regression analysis did reveal a significant difference between calculated and measured VHI. The VHI and V-RQOL are highly correlated; however, this study suggests that the two instruments are not interchangeable for individuals.
