Dysphonia in Children; Clinical Profile, Conservative Treatment Modalities and Outcomes: An Institutional Experience. Indian J Otolaryngol Head Neck Surg 2023; 75:3248-3255. [PMID: 37974702 PMCID: PMC10646136 DOI: 10.1007/s12070-023-03952-6] [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: 05/26/2023] [Accepted: 06/08/2023] [Indexed: 11/19/2023] Open
Abstract
Dysphonia in children represents broad-spectrum voice problems. Global prevalence of hoarseness in school-aged children is 6-23%. It impairs communication of child, thus affects social life. This study shows importance of appropriate preventive measures for paediatric dysphonia and diagnosis of voice problems in early stages. Continuous voice abuse in children can cause recurrent voice disorders as well as speech problems. This prospective study included 104 patients(78 males and 26 females) of 6-15 years, with voice problems, in a tertiary care centre, North Kerala, during June 2022-March 2023. Chief complaints and risk factors evaluated. Voice analysis using maximum phonation time (MPT), Child Voice Handicap Index for Parents (CVHI-10-P), Reflux Symptom Index (RSI) and clinical examination including indirect laryngoscopy (IDL) and 70degree scopy were done. Treatment given for a maximum of 2 weeks. Advised voice rest and voice therapy throughout. All patients followed up after 2 weeks and up to 3 months. Voice abuse was the commonest risk factor and voice change, the commonest symptom. MPT reduced in 23% males and 14% females. According to CVHI-10-P, screaming was present in 52% children and symptoms present mostly in afternoon. RSI identified the role of LPRD in dysphonia. IDL and 70 scopy identified most common diagnosis as vocal nodule. Treatment given and follow-up period noted. All except vocal polyp had complete relief. Most common diagnosis was vocal nodule which resulted from chronic voice abuse. Appropriate preventive measures, early diagnosis and adequate treatment of voice problems should be considered. Conservative management in early stages is recommended.

Abstract
To determine the prevalence of laryngeal pathology in children presenting with cleft palate with or without cleft lip (CP ± L) who underwent nasoendoscopy to assess palatal function. A secondary aim was to determine the relationship between patient demographics, resonance, articulation, and prevalence of laryngeal pathology in this population. Retrospective, observational cohort study. Outpatient pediatric cranio-facial anomalies clinic. Children ≤18 years of age presenting with CP ± L (N = 215) who underwent nasoendoscopy, speech language pathology, plastic surgery, and otolaryngological evaluations between 2009 and 2020. Laryngeal diagnosis by pediatric otolaryngologists. 21.9% of children presented with laryngeal pathology. Diagnoses included benign vocal fold lesions and laryngeal edema sufficiently severe to alter vocal fold edge contour. Likelihood of laryngeal pathology increased by approximately 12% with every increase of 1 year in age (P = .001, OR = 1.12). Children with laryngeal pathology were 50% more likely to have undergone palatal repair (P < .001, OR = 1.50). In addition, children with severely hypernasal resonance were 78% less likely to present with laryngeal pathology (P =.046, OR = 0.22). This population is at increased risk for laryngeal pathologies as determined by nasoendoscopy. This finding underscores the importance of careful laryngeal imaging in assessing these children. Additional research is warranted to identify the mechanisms underlying the increased risk for morphological vocal fold changes.

Abstract
PURPOSE The purpose of this study was to develop a novel teacher-reported pediatric voice outcome measure and to investigate its psychometric properties. METHOD In the first stage, a new instrument, the Teacher-Reported Pediatric Voice Handicap Index (TRPVHI), was developed. After item generation, a panel of experts evaluated the items to assess the content validity. Subsequently, the final version of the preliminary instrument was applied to teachers of 306 children (57 dysphonic and 249 vocally healthy) between the ages of 4 and 11 years. Eventually, the construct validity, criterion-related validity, test-retest reliability, and internal consistency of the developed instrument were examined. RESULTS The items with a content validity ratio less than .8 were modified or removed, and accordingly, the preliminary version of the index was finalized. After the application of the preliminary version, item reduction was made based on the factor analysis. The index is composed of 27 questions and three subscales: Functional, Physical, and Emotional. A significant difference was observed between the dysphonic and vocally healthy children for the TRPVHI scores (p < .001). A positive moderate correlation was determined between the Pediatric Voice Handicap Index and TRPVHI scores. Correlation coefficients between the test and retest scores of the TRPVHI were in the range of .92-.98. Cronbach's alpha values computed to assess the internal consistency were in the range of .94-.98. CONCLUSIONS The TRPVHI is the only valid and reliable teacher-reported outcome measure of the effects of voice disorders on children. It is anticipated that the deployment of the TRPVHI in conjunction with other subjective tools, both in the initial evaluation and the follow-up of the treatment results, will allow a better understanding of the physical, functional, and emotional effects of voice disorders on children. Furthermore, it can potentially lead further research to enable the use of the TRPVHI for screening purposes.

The Others Are Too Loud! Children's Experiences and Thoughts Related to Voice, Noise, and Communication in Nordic Preschools. Front Psychol 2019; 10:1954. [PMID: 31496984 PMCID: PMC6712832 DOI: 10.3389/fpsyg.2019.01954] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2019] [Accepted: 08/08/2019] [Indexed: 11/14/2022] Open
Abstract
BACKGROUND High noise levels affect hearing, voice use, and communication. Several studies have reported high noise levels in preschools and impaired voice quality in children. Noise and poor listening conditions impair speech comprehension in children more than in adults and even more for children with hearing or language impairment, attention deficits, or another first language. AIM The aim of this study was to explore how children in Finland, Sweden, and Iceland describe the preschool environment in relation to noise, voice, and verbal communication; what were their experiences, knowledge and ideas in relation to voice, noise, and communication. Children's awareness of effects of noise, reactions, and coping strategies were also studied. In addition, country and gender differences were analyzed. METHODS Eighteen Icelandic, 14 Finnish, and 16 Swedish children were interviewed using a common interview-guide. Swedish and Finnish children were interviewed in focus groups and Icelandic children individually. All interviews were transcribed verbatim and analyzed thematically by the native speaker. The interviews were translated to English to be re-analyzed for inter-judge reliability of identified themes. Inter-judge reliability was calculated using percentage absolute agreement. RESULTS The interviews resulted in 1052 utterances, 471 from focus groups, and 581 from individual interviews. Three themes were identified, Experiences, Environment, and Strategies with two to three subcategories. Inter-judge agreement for the themes was excellent, 92-98%. Experiences occurred in 55% of the utterances. The subcategories were bodily and emotional experiences and experiences of hearing and being heard. Environment occurred in 20% of the utterances, with subcategories indoor vs. outdoor and noise. Strategies was found in 15%, with subcategories games and problem oriented actions. The only significant difference between the countries was for the theme Strategies where the Swedish children produced more utterances than the Finnish. No gender differences were found. CONCLUSION Children are aware of high noise levels and mainly blame other children for making noise and shouting. They describe reactions and strategies related to noise like impaired communication and effects on hearing but are less aware of effects on voice. Expressed thoughts were similar across countries. No gender differences were found.

Associations of Speaking-Voice Parameters With Personality and Behavior in School-Aged Children. J Voice 2018; 34:485.e23-485.e31. [PMID: 30391018 DOI: 10.1016/j.jvoice.2018.09.022] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2018] [Revised: 09/27/2018] [Accepted: 09/28/2018] [Indexed: 10/28/2022]
Abstract
OBJECTIVES Previous studies suggest a link between voice disorders and personality traits. However, nearly nothing is known about the relationship between personality and voice parameters in healthy children. The present study investigated associations between children's personality and the intensity and frequency of their speaking voice. STUDY DESIGN This is a cross-sectional analysis. METHODS The study participants included 871 German children aged from 7 to 14 who had not yet experienced voice change in puberty. Within the framework of the LIFE Child study, all participants were asked to perform a speaking-voice task at four different intensity levels (quietest, conversational, presentation, and shouting voice). Associations of fundamental frequency and voice intensity with children's personality and behavioral strengths and difficulties (assessed using parent-reported questionnaires) were estimated using multiple linear regression analyses. RESULTS With respect to children's personality, the analyses revealed significant positive associations between speaking-voice intensity and extraversion (eg, for the conversational voice, β = 0.16, P < 0.001) as well as significant negative associations between voice intensity and emotional stability (eg, for the shouting voice, β = -0.15, P = 0.004) and conscientiousness (for the shouting voice, β = -0.10, P = 0.033). Regarding behavioral strengths and difficulties, we observed significant positive associations between voice intensity and peer-relationship problems (eg, for the conversational voice, β = 0.14, P = 0.001) and prosocial behavior (for the conversational voice, β = 0.11, P = 0.015). In contrast, no significant association was found between speaking fundamental frequency and personality or behavioral difficulties/strengths. CONCLUSIONS In children, associations exist between a child's speaking-voice intensity and his or her personality, especially extraversion and emotional stability, and behavioral characteristics.

Respiratory Tract Infections and Voice Quality in 4-Year-old Children in the STEPS Study. J Voice 2018; 33:801.e21-801.e25. [PMID: 29506899 DOI: 10.1016/j.jvoice.2018.01.021] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2017] [Accepted: 01/18/2018] [Indexed: 11/17/2022]
Abstract
OBJECTIVES Health-related factors are part of the multifactorial background of dysphonia in children. Respiratory tract infections affect the same systems and structures that are used for voice production. The purpose of this study was to investigate if the number of respiratory tract infections or the viral etiology were significant predictors for a more hoarse voice quality. METHODS The participants were 4-year-old children who participated in the multidisciplinary STEPS study (Steps to the Healthy Development and Well-being of Children) where they were followed up from pregnancy or birth to 4 years of age. Data were collected through questionnaires and a health diary filled in by the parents. Some of the children were followed up more intensively for respiratory tract infections during the first 2 years of life, and nasal swab samples were taken at the onset of respiratory symptoms. Our participants were 489 of these children who had participated in the follow-up for at least 1 year and for whom data on respiratory tract infections and data on voice quality were available. RESULTS The number of hospitalizations due to respiratory tract infections was a significant predictor for a more hoarse voice quality. Neither the number of rhinovirus infections nor the number of respiratory syncytial virus infections was statistically significant predictors for a more hoarse voice quality. CONCLUSIONS Based on our results, we would suggest including questions on the presence of respiratory tract infections that have led to hospitalization in the pediatric voice anamnesis. Whether the viral etiology of respiratory tract infections is of importance or not requires further research.

Abstract
Objective This guideline provides evidence-based recommendations on treating patients who present with dysphonia, which is characterized by altered vocal quality, pitch, loudness, or vocal effort that impairs communication and/or quality of life. Dysphonia affects nearly one-third of the population at some point in its life. This guideline applies to all age groups evaluated in a setting where dysphonia would be identified or managed. It is intended for all clinicians who are likely to diagnose and treat patients with dysphonia. Purpose The primary purpose of this guideline is to improve the quality of care for patients with dysphonia, based on current best evidence. Expert consensus to fill evidence gaps, when used, is explicitly stated and supported with a detailed evidence profile for transparency. Specific objectives of the guideline are to reduce inappropriate variations in care, produce optimal health outcomes, and minimize harm. For this guideline update, the American Academy of Otolaryngology—Head and Neck Surgery Foundation selected a panel representing the fields of advanced practice nursing, bronchoesophagology, consumer advocacy, family medicine, geriatric medicine, internal medicine, laryngology, neurology, otolaryngology–head and neck surgery, pediatrics, professional voice, pulmonology, and speech-language pathology. Action Statements The guideline update group made strong recommendations for the following key action statements (KASs): (1) Clinicians should assess the patient with dysphonia by history and physical examination to identify factors where expedited laryngeal evaluation is indicated. These include, but are not limited to, recent surgical procedures involving the head, neck, or chest; recent endotracheal intubation; presence of concomitant neck mass; respiratory distress or stridor; history of tobacco abuse; and whether the patient is a professional voice user. (2) Clinicians should advocate voice therapy for patients with dysphonia from a cause amenable to voice therapy. The guideline update group made recommendations for the following KASs: (1) Clinicians should identify dysphonia in a patient with altered voice quality, pitch, loudness, or vocal effort that impairs communication or reduces quality of life (QOL). (2) Clinicians should assess the patient with dysphonia by history and physical examination for underlying causes of dysphonia and factors that modify management. (3) Clinicians should perform laryngoscopy, or refer to a clinician who can perform laryngoscopy, when dysphonia fails to resolve or improve within 4 weeks or irrespective of duration if a serious underlying cause is suspected. (4) Clinicians should perform diagnostic laryngoscopy, or refer to a clinician who can perform diagnostic laryngoscopy, before prescribing voice therapy and document/communicate the results to the speech-language pathologist (SLP). (5) Clinicians should advocate for surgery as a therapeutic option for patients with dysphonia with conditions amenable to surgical intervention, such as suspected malignancy, symptomatic benign vocal fold lesions that do not respond to conservative management, or glottic insufficiency. (6) Clinicians should offer, or refer to a clinician who can offer, botulinum toxin injections for the treatment of dysphonia caused by spasmodic dysphonia and other types of laryngeal dystonia. (7) Clinicians should inform patients with dysphonia about control/preventive measures. (8) Clinicians should document resolution, improvement or worsened symptoms of dysphonia, or change in QOL of patients with dysphonia after treatment or observation. The guideline update group made a strong recommendation against 1 action: (1) Clinicians should not routinely prescribe antibiotics to treat dysphonia. The guideline update group made recommendations against other actions: (1) Clinicians should not obtain computed tomography (CT) or magnetic resonance imaging (MRI) for patients with a primary voice complaint prior to visualization of the larynx. (2) Clinicians should not prescribe antireflux medications to treat isolated dysphonia, based on symptoms alone attributed to suspected gastroesophageal reflux disease (GERD) or laryngopharyngeal reflux (LPR), without visualization of the larynx. (3) Clinicians should not routinely prescribe corticosteroids for patients with dysphonia prior to visualization of the larynx. The policy level for the following recommendation about laryngoscopy at any time was an option: (1) Clinicians may perform diagnostic laryngoscopy at any time in a patient with dysphonia. Disclaimer This clinical practice guideline is not intended as an exhaustive source of guidance for managing dysphonia (hoarseness). 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 it may not provide the only appropriate approach to diagnosing and managing this problem. Differences from Prior Guideline (1) Incorporation of new evidence profiles to include the role of patient preferences, confidence in the evidence, differences of opinion, quality improvement opportunities, and any exclusion to which the action statement does not apply (2) Inclusion of 3 new guidelines, 16 new systematic reviews, and 4 new randomized controlled trials (3) Inclusion of a consumer advocate on the guideline update group (4) Changes to 9 KASs from the original guideline (5) New KAS 3 (escalation of care) and KAS 13 (outcomes) (6) Addition of an algorithm outlining KASs for patients with dysphonia

Abstract
OBJECTIVE To evaluate the effect of dysphonia in children, several methods have been developed, including the Pediatric Voice Outcome Survey, the Pediatric Voice Handicap Index, and the Pediatric Voice-Related Quality of Life (PVRQOL) Survey. The aim of this study was to analyze the validity of the Turkish version of the PVRQOL Survey. METHODS The PVRQOL Survey consists of 10 questions that evaluate the effects of dysphonia on quality of life. We translated it into Turkish by working with two translators and faculty from the English Grammar and Literature Department. The Turkish version was translated back into English by two bilingual individuals to assess accuracy. The final version was tested by 15 parents for pilot study. Following the pilot study, we enrolled 52 children who had been admitted to the outpatient clinic with dysphonia and 79 children who had no voice complaints. The parents of the children under 7 years were asked to answer the survey. Children aged between 7 and 9 years completed the survey with their parents, and children over 9 years completed the survey by themselves. RESULTS The results of the pilot study revealed no difference between the two groups. Intergroup comparisons revealed that there were statistically significant differences between the control and patient groups in terms of question responses. When the total scores of the two groups were compared, there was a significant difference. CONCLUSION The Turkish version is a valid and reliable instrument for assessing dysphonic patients and healthy subjects.

Vocal Symptoms and Voice Quality in Children With Allergy and Asthma. J Voice 2017; 31:515.e9-515.e14. [PMID: 28108152 DOI: 10.1016/j.jvoice.2016.12.010] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/02/2016] [Accepted: 12/16/2016] [Indexed: 11/25/2022]
Abstract
OBJECTIVES The background for dysphonia is multifactorial, and health-related factors have been listed among the factors affecting voice. In previous studies with adult participants, allergy and asthma have been indicated to have a connection to vocal symptoms. With the majority of previous research being studies involving adult participants, it is unclear what the effect of allergy and asthma on children's voices is. The aim of this study was to investigate if allergies and asthma are risk factors for having vocal symptoms. METHODS The material was collected through paper questionnaires distributed to the parents of new pediatric patients at an allergy clinic. The participants were 108 children aged 9 months to 17 years and 1 month. RESULTS Of the children whose parents had filled in the questions on vocal symptoms, 18.2% (n = 18) had frequently occurring vocal symptoms, which was defined as having two or more vocal symptoms every week or more often. The most common vocal symptoms were throat clearing and coughing. There was a significant connection between inhalant allergy and having frequently occurring vocal symptoms. The connection between cough that lasted for more than 4 weeks and having frequently occurring vocal symptoms was also significant. In this study, we found no significant connection between having an asthma diagnosis and having frequently occurring vocal symptoms. CONCLUSIONS Based on the results of this study, voice screening for children with inhalant allergy would be advisable. Prolonged cough should be taken seriously and be treated, as the mechanical trauma caused by cough seems to have a connection to vocal symptoms.

Abstract
OBJECTIVES A well-functioning voice is becoming increasingly important because voice-demanding professions are increasing. The largest proportion of voice disorders is caused by factors in the environment. Moisture damage is common and can initiate microbial growth and/or diffusion of chemicals from building materials. Indoor air problems due to moisture damage are associated with a number of health symptoms, for example, rhinitis, cough, and asthma symptoms. The purpose of this study was to investigate if children attending a day care center, preschool, or school with indoor air problems due to moisture damage were hoarse more often than the children in a control group. METHODS Information was collected through electronic and paper questionnaires from the parents of 6- to 9-year-old children (n = 1857) attending 57 different day care centers, preschools, or schools with or without indoor air problems due to moisture damage. RESULTS The results showed a significant correlation between the degree of indoor air problem due to moisture damage and the frequency of hoarseness. Significant predictors for the child being hoarse every week or more often were dry cough, phlegm cough, and nasal congestion. CONCLUSIONS The results indicate that these symptoms and exposure to indoor air problems due to moisture damage should be included in voice anamnesis. Furthermore, efforts should be made to remediate indoor air problems due to moisture damage and to treat health symptoms.

Abstract
OBJECTIVE The aim of this study was to assess the long term results of treatment and rehabilitation of childhood dysphonia. METHODS This study included a group of adolescents (n=29) aged from 15 to 20 who were treated due to pediatric hyperfunctional dysphonia and soft vocal fold nodules during their pre-mutational period (i.e. between 5 and 12 years of age). The pre-mutational therapy was comprised of proper breathing pattern training, voice exercises and psychological counseling. Laryngostroboscopic examination and perceptual analysis of voice were performed in each patient before treatment and one to four years after mutation was complete. The laryngostroboscopic findings, i.e. symmetry, amplitude, mucosal wave and vocal fold closure, were graded with NAPZ scale, and the GRBAS scale was used for the perceptual voice analysis. RESULTS Complete regression of the childhood dysphonia was observed in all male patients (n=14). Voice disorders regressed completely also in 8 out of 15 girls, but symptoms of dysphonia documented on perceptual scale persisted in the remaining seven patients. CONCLUSIONS Complex voice therapy implemented in adolescence should be considered as either the treatment or preventive measure of persistent voice strain, especially in girls.

Pediatric high speed digital imaging of vocal fold vibration: a normative pilot study of glottal closure and phase closure characteristics. Int J Pediatr Otorhinolaryngol 2012; 76:954-9. [PMID: 22445799 PMCID: PMC3372768 DOI: 10.1016/j.ijporl.2012.03.004] [Citation(s) in RCA: 32] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/28/2011] [Revised: 02/29/2012] [Accepted: 03/03/2012] [Indexed: 11/30/2022]
Abstract
OBJECTIVE The aim of the study is to characterize normal vibratory patterns of both glottal closure and phase closure in the pediatric population with the use of high speed digital imaging. METHODS For this prospective study a total of 56 pre-pubertal children, 5-11 years (boys=28, girls=28) and 56 adults, 21-45 years (males=28, females=28) without known voice problems were examined with the use of a new technology of high speed digital imaging. Recordings were captured at 4000 frames per second for duration of 4.094 s at participants' typical phonation. With semi-automated software, montage analysis of glottal cycles was performed. Three trained experienced raters, rated features of glottal configuration and phase closure from glottal cycle montages. RESULTS Posterior glottal gap was the predominant glottal closure configuration in children (girls=85%, boys=68%) with normal voice. Other glottal configurations observed were: anterior gap (girls=3.6%, boys=0%), complete closure (girls=7%, boys=10%) and hour glass (girls=0%, boys=11%). Adults with normal voice also demonstrated predominantly higher percentage of posterior glottal gap configuration (females=75% male=54%) compared to the configurations of anterior gap (females=0% male=7%), complete closure (females=2% male=39%), hour glass (females=3.6% male=3.6%). A predominantly open phase (51-70% of the glottal cycle) was observed in 86% girls and 71% boys. Compared to children, adult females showed a predominantly balance phased closure 46%, followed by open phase (39%) and predominantly closed phase (14%). Adult males showed a predominantly closed phase (43%), followed by predominantly open phase (39%), followed by a balanced phase (18%). CONCLUSIONS This is a first study investigating characteristics of normal vibratory motion in children with high speed digital imaging. Glottal configuration and phase closure for children with normal voices are distinctly different compared to adults. The results suggest that posterior glottal gap and a predominantly open phase of the glottal cycle should be considered as normal glottal configuration in children during modal pitch and loudness. This study provides preliminary information on the vibratory characteristics of children with normal voice. The data presented here may provide the bases for differentiating normal vibratory characteristics from the disordered in the pediatric population.

Abstract
Tonsillar hypertrophy is common in young children and affects several aspects of the speech such as distortions of the dento-alveolar consonants. The study objective was to assess /s/-articulation, perceptually and acoustically, in children with tonsillar hypertrophy and compare effects of two types of surgery, total tonsillectomy and tonsillotomy. Sixty-seven children, aged 50-65 months, on the waiting list for surgery, were randomized to tonsillectomy or tonsillotomy. The speech material was collected preoperatively and 6 months postoperatively. Two groups of age-matched children were controls. /S/-articulation was affected acoustically with lower spectral peak locations and perceptually with less distinct /s/-production before surgery, in comparison to controls. After surgery /s/-articulation was normalized perceptually, but acoustic differences remained. No significant differences between surgical methods were found.

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.

Abstract
This study was carried out using a transversal design. It aimed to investigate possible changes of the normal voice in children before mutation, to create a database for the parameters used in the study, and to examine the use of fractal dimension and the largest Lyapunov exponent (LLE) in the assessment of nonpathological phenomena. Two hundred twelve children were enrolled: 111 females and 101 males; and 9 six-year-olds, 24 seven-year-olds, 18 eight-year-olds, 25 nine-year-olds, 27 ten-year-olds, 55 eleven-year-olds, and 54 twelve-year-olds. Fundamental frequency (Fo) decreased with age and was lower in boys than in girls. Jitter and shimmer did not significantly differ with age or gender. Fractal dimension and LLE were significantly lower in boys; LLE decreased with age. The present series confirmed the established findings that Fo is lower in boys than in girls, even before mutation, and decreases with age; two other classical voice analysis parameters, jitter and shimmer, also showed the same behavior as described in the literature. The study of nonlinear parameters (fractal dimension and LLE) showed that laryngeal dynamics is more stable in boys than in girls, and that stability is correlated with age.

Abstract
The families of nine children with deviant voice qualities were selected for family treatment according to the SYGESTI model. Recordings of the children's speech were made before and after therapy. Perceptual evaluation of their voice quality showed significant improvement in various perceptual parameters after the therapy. Acoustical analysis confirmed changes of voice quality and mean fundamental frequency in speech. The therapy also was found to improve relations between family members, conflict management and other aspects of communication. The results suggest that these children's deviant voices were related to family conditions.

Abstract
Preschool teachers are at risk for developing voice problems such as vocal fatigue and vocal nodules. The purpose of this report was to study preschool teachers' voice use during work. Ten healthy female preschool teachers working at daycare centers (DCC) served as subjects. A binaural recording technique was used. Two microphones were placed on both sides of the subject's head, at equal distance from the mouth, and a portable DAT recorder was attached to the subject's waist. Recordings were made of a standard reading passage before work (baseline) and of spontaneous speech during work. The recording technique allowed separate analyses of the level of the background noise, and of the subjects' voice sound pressure level, mean fundamental frequency, and total phonation time. Among the results, mean background noise level for the ten DCCs was 76.1 dBA (range 73.0-78.2), which is more than 20 dB higher than what is recommended where speech communication is important (50-55 dBA). The subjects spoke on an average of 9.1 dB louder (p < 0.0001), and with higher mean fundamental frequency (247 Hz) during work as compared to the baseline (202 Hz) (p < 0.0001). Mean phonation time for the group was 17%, which was considered high. It was concluded that preschool teachers do have a highly vocally demanding profession. Important steps to reduce the vocal loading for this occupation would be to decrease the background noise levels and include pauses so that preschool teachers can rest their voices.

Abstract
Long-term average spectrum (LTAS) analysis offers representative information on voice timbre providing spectral information averaged over time. It is particularly useful when persistent spectral features are under investigation. The aim of this study was to compare perceived sex of children to the LTAS analysis of their audio signals. A total of 320 children, aged between 3 and 12 years, were recorded singing a song. In an earlier analysis, the recorded voices were evaluated with respect to perceived and actual sex by experienced listeners. From this group, a subgroup of 59 children (30 boys and 29 girls) was selected. The mean LTAS revealed a peak at 5 kHz for children perceived with confidence as boys, and a flat spectrum at 5 kHz for children perceived confidently as girls (whether male or female in actuality).
