Management of velopharyngeal insufficiency: development of a protocol and modifications of sphincter pharyngoplasty

Velopharyngeal Gap Size During Sustained Vowel Production Correlates With Perceptual Ratings of Hypernasality in Connected Speech

PURPOSE

The purpose of this study was to investigate the relationship between perceptual ratings of hypernasality made during connected speech and velopharyngeal (VP) gap size measured in millimeters in the sagittal plane during sustained vowel production using magnetic resonance imaging (MRI).

METHOD

A retrospective cross-sectional analysis was completed. A subgroup of 110 participants from another study with an Mage of 10.1 years presenting for management of VP insufficiency was included. Perceptual ratings of hypernasality during connected speech and measurement of gap size during sustained /i/ production on MRI were performed by raters blinded to the participants' medical and surgical history.

RESULTS

There was a moderate-to-strong, positive correlation (r = .61; p < .001) between hypernasality ratings and VP gap size measured on MRI using sustained /i/. The odds of a higher hypernasality rating increased as the gap size increased (odds ratio = 1.34; 95% CI [1.20, 1.49]; p < .001). The predicted probability for hypernasality ratings of none/minimal/mild steadily decreased as the gap size increased indicating that lower ratings of hypernasality were associated with smaller gap sizes. For the rating of "moderate" hypernasality, the predicted probability of the rating steadily increased up to 8 mm and then decreased as the gap size continued to increase. The predicted probability for a hypernasality rating of "severe" consistently increased as the gap size increased.

CONCLUSIONS

Hypernasality ratings made at the connected speech level were significantly associated with VP gap size as measured during sustained vowel production. These findings suggest sustained vowel production elicited on MRI may adequately characterize VP gap size in the evaluation of VP insufficiency.

Collaboration of Surgeons and Speech Pathologists in the Selection of Optimal Treatment; Role of Speech Pathologist and Audiologist in the Interdisciplinary Management of Patients With Clefts

Children born with cleft lip and/or cleft palate may have problems with feeding, speech, and hearing. Collaboration of surgeons and speech pathologists guide cleft care treatment decisions and vary throughout the cleft timeline. This review aims to discuss the role of the speech pathologist and audiologist in the interdisciplinary management of patients with cleft lip and palate, specifically, how the speech pathologists' findings guide surgical decision-making.

Does Notching Along the Nasal Velar Surface During Nasopharyngoscopy Predict Discontinuity of the Underlying Levator Veli Palatini Muscle?

To determine the sensitivity and specificity of velar notching seen on nasopharyngoscopy for levator veli palatini (LVP) muscle discontinuity and anterior positioning.

Nasopharyngoscopy and MRI of the velopharynx were performed on patients with VPI as part of their routine clinical care. Two speech-language pathologists independently evaluated nasopharyngoscopy studies for the presence or absence of velar notching. MRI was used to evaluate LVP muscle cohesiveness and position relative to the posterior hard palate. To determine the accuracy of velar notching for detecting LVP muscle discontinuity, sensitivity, specificity, and positive predictive value (PPV) were calculated.

A craniofacial clinic at a large metropolitan hospital.

PARTICIPANTS

Thirty-seven patients who presented with hypernasality and/or audible nasal emission on speech evaluation and completed nasopharyngoscopy and velopharyngeal MRI study as part of their preoperative clinical evaluation.

Among patients with partial or total LVP dehiscence on MRI, presence of a notch accurately identified discontinuity in the LVP 43% (95% CI 22-66%) of the time. In contrast, the absence of a notch accurately indicated LVP continuity 81% (95% CI 54-96%) of the time. The PPV for the presence of notching to identify a discontinuous LVP was 78% (95% CI 49-91%). The distance from the posterior edge of the hard palate to the LVP, known as effective velar length, was similar in patients with and without notching (median 9.8 mm vs 10.5 mm, P = 1.00).

The observation of a velar notch on nasopharyngoscopy is not an accurate predictor of LVP muscle dehiscence or anterior positioning.

Can MRI Replace Nasopharyngoscopy in the Evaluation of Velopharyngeal Insufficiency?

OBJECTIVE

To investigate whether flexible nasopharyngoscopy, when performed in addition to magnetic resonance imaging (MRI), influences the type of surgery selected or success of surgery in patients with velopharyngeal insufficiency (VPI).

DESIGN

Cohort study.

SETTING

A metropolitan children's hospital.

PATIENTS

Patients with non-syndromic, repaired cleft palate presenting for management of VPI.

INTERVENTIONS

MRI and nasopharyngoscopy or MRI alone for preoperative imaging of the velopharyngeal mechanism.

MAIN OUTCOME MEASURES

(1) Surgical selection and (2) resolution of hypernasality. All speech, MRI, and nasopharyngoscopy measurements were performed by raters blinded to patients' medical and surgical history.

RESULTS

Of the 25 patients referred for nasopharyngoscopy, 76% completed the exam. Of the 41 patients referred for MRI, the scan was successfully completed by 98% of patients. Completion of nasopharyngoscopy was significantly (p=0.01) lower than MRI. Surgical selection did not significantly differ (p=0.73) between the group receiving MRI and nasopharyngoscopy and the group receiving MRI alone, nor was there a significant difference between these groups in the proportion of patients achieving resolution of hypernasality postoperatively (p=0.63). Percent total velopharyngeal closure assessments on nasopharyngoscopy and MRI were strongly correlated (r=0.73).

CONCLUSIONS

In patients receiving MRI as part of their preoperative VPI evaluation, the addition of nasopharyngoscopy did not result in a difference in surgical selection or resolution of hypernasality. Routine inclusion of nasopharyngoscopy may not be necessary for the evaluation of velopharyngeal anatomy when MRI is available.

Simulation of Velopharyngeal Biomechanics Identifies Differences in Sphincter Pharyngoplasty Outcomes: A Matched Case-Control Study

The purpose of this study was to develop a framework for 3D subject-specific computational models capable of simulating velopharyngeal biomechanics for anatomic changes that occur following pharyngoplasty and to gain insight into biomechanical factors that may lead to different speech/surgical outcomes. Patient-specific models for two, matched participants with differing speech/surgical outcomes were developed: one with a successful pharyngoplasty outcome and one with a failed pharyngoplasty outcome. Surgical scenarios were simulated to model pharyngoplasty location, identify LVP muscle biomechanics, and identify an optimal pharyngoplasty location for each participant. These simulations illustrate the potential for optimizing pharyngoplasties based on patient-specific geometry.

Sphincter Pharyngoplasty for Velopharyngeal Dysfunction: Impact of 22q11.2 Deletion Syndrome

OBJECTIVE

Patients with 22q11.2 deletion syndrome (22q11DelS) often present with velopharyngeal dysfunction (VPD). VPD in patients with 22q11DelS is multifactorial beyond velopharyngeal insufficiency (VPI) alone, and differences in surgical outcomes are poorly understood. Our objective was to determine whether patients with 22q11DelS have an increased risk for persistent VPI after sphincter pharyngoplasty compared to patients without 22q11DelS.

METHODS

We completed a retrospective cohort study of patients with 22q11DelS undergoing sphincter pharyngoplasty between 1995 and 2019 using a VPD clinic database. Patients with 22q11DelS were compared to a cohort of 2:1 frequency-matched (age, degree of velopharyngeal closure) patients without 22q11DelS. Variables included patient characteristics, surgical history, perceptual speech evaluation, and degree of closure on nasopharyngoscopic evaluations. Primary outcomes included postoperative VPI severity and hypernasality. Speech and nasopharyngoscopic characteristics were compared using Fisher's exact test. Postoperative VPI severity and hypernasality were compared between groups via relative risks (RR) from mixed effects Poisson regression models, with random effects of age and velopharyngeal closure.

RESULTS

134 patients (51 22q11DelS, 83 matched) were included, with mean age of 7.3 years (standard deviation 3.0) and 50% male. Cohorts had similar preoperative speech characteristics and nasopharyngoscopic findings. Patients with 22q11DelS had similar postoperative VP function as patients without 22q11DelS (RR 0.85, CI 0.46-1.57 for VPI severity, RR 0.83, CI 0.45-1.53 for hypernasality). Even after adjusting by preoperative variables, no differences were seen between both groups.

CONCLUSION

Matched for age and pre-operative velopharyngeal closure, patients with and without 22q11DelS and VPI had similar benefits after sphincter pharyngoplasty.

A Master Mind Game Code Algorithm Approach to Help Surgical Decision-Making between Retropharyngeal Fat Grafting and Pharyngoplasty for the Treatment of Velopharyngeal Incompetence

Introduction Velopharyngeal insufficiency (VPI) is a controversial pathology with many surgical options.

Objective To compare pharyngoplasty and retropharyngeal fat grafting and to build a prognostic tool to achieve perfect speech.

Methods Retrospective observational cohort study of 114 patients operated for VPI from 1982 to 2019 in a single tertiary center. The instrumental assessment was made using an aerophonoscope and nasofibroscopy. The variables sex, age, genetic syndromes, and type of diagnosis were analyzed with logistic regression model adjusted with propensity score. To generalize results and to build a surgical predictive tool, a marginal analysis concludes the study.

Results Among the patients (median [range] age 7 [4–48]), 63 (55.26%) underwent pharyngoplasty and 51 (44.74%) graft. The graft group had no complication, but it had a failure rate of 7.84%. The pharyngoplasty group had no failure, but one patient had postoperative obstructive sleep apnea. The marginal analysis demonstrated that age lower than 7 years, cleft lip and palate, absence of syndrome, and intermittent VPI were important predictive factors of good result regardless of surgical technique.

Conclusions Without a statistical demonstration of the superiority of pharyngoplasty over graft, and in the uncertainty of literature background, our perfect-speech patient profile represents an important tool for a postoperative forecast of results in which, like in the Master Mind game, every feature has to be considered not individually but as a pattern of characteristics whose association contributes to the outcome.

Revision Pharyngoplasty in Cleft Palate and Velopharyngeal Insufficiency: Management and Outcomes

INTRODUCTION

Velopharyngeal insufficiency (VPI), a stigmatizing hallmark of palatal dysfunction, occurs in a wide spectrum of pediatric craniofacial conditions. The mainstays for surgical correction include palate repair and/or pharyngeal surgery. However, primary pharyngoplasty has a failure rate of 15% to 20%. Although revision pharyngoplasty may be necessary in those with persistent VPI, little is known regarding the indications for and outcomes after such procedures. The purpose of this study is to describe the authors' experience with indications for and outcomes after revision pharyngoplasty.

METHODS

A single-center retrospective review was performed of all patients undergoing revision pharyngoplasty between 2002 and 2019. Demographic data and Pittsburgh Weighted Speech Scores, diagnoses, comorbidities, and complications were tabulated. Two-tailed Student t test was used, and a P value of 0.05 or less was considered statistically significant.

RESULTS

Thirty-two patients (65.6% male) met inclusion criteria for this study. The most common diagnoses included cleft palate (68.8%), submucous cleft palate (SMCP, 18.8%), and congenital VPI (6.3%, likely occult SMCP). Most patients (84.4%) underwent palatoplasty before their initial pharyngoplasty. The primary indication for initial pharyngoplasty was VPI (mean age 7.1 ± 4.6 years). The most common indication for revision pharyngoplasty (mean age 11.2 ± 5.1 years) included persistent VPI (n = 22), followed by obstructive sleep apnea (OSA) (n = 11). Persistent VPI (n = 8) and OSA (n = 6) were the most common complications after secondary pharyngoplasty. Thirteen patients (40.6%) within the revision pharyngoplasty cohort required additional surgical intervention: 4 underwent tertiary pharyngoplasty, 4 underwent takedown for OSA (n = 3) or persistent VPI (n = 1), 3 underwent takedown and conversion Furlow for persistent VPI (n = 2), OSA (n = 2) and/or flap dehiscence (n = 1), and 2 underwent palatal lengthening with buccal myomucosal flaps for persistent VPI. Of the 4 patients who required a tertiary pharyngoplasty, the mean age at repair was 6.6 ± 1.1 years and their speech scores improved from 13.5 to 2.3 after tertiary pharyngoplasty (P = 0.11). The overall speech score after completion of all procedures improved significantly from 19 to 3.3.

CONCLUSION

Patients who fail primary pharyngoplasty represent a challenging population. Of patients who underwent secondary pharyngoplasty, nearly half required a tertiary procedure to achieve acceptable speech scores or resolve complications.

Speech Outcomes After Sphincter Pharyngoplasty for Velopharyngeal Insufficiency

OBJECTIVES/HYPOTHESIS

To investigate perceptual speech outcomes following sphincter pharyngoplasty (SP) and to identify patient characteristics associated with velopharyngeal insufficiency (VPI) resolution or improvement.

METHODS

Retrospective review of prospectively collected data was performed of consecutive patients that underwent SP for management of VPI between 1994 and 2016 at a single tertiary care pediatric hospital. Demographic data, nasendoscopic findings, and speech characteristics were recorded using a standardized protocol. Pre- and post-operative VPI was graded on a five-point Likert scale. Frequency of post-operative VPI resolution and improvement was assessed and associations with patient characteristics were analyzed. The association between odds of VPI resolution or improvement and five patient characteristics identified a priori was performed controlling for confounding factors.

RESULTS

Two-hundred ninety-six subjects were included. All patients had at least minimal VPI pre-operatively; 72% were graded moderate or severe. Sixty-four percent experienced resolution and 83% improved at least one point on the VPI-severity scale. Of the five patient characteristics, only history of cleft palate repair was significantly associated with decreased odds of VPI improvement but not resolution when controlling for other variables.

CONCLUSIONS

Sphincter pharyngoplasty resulted in resolution of VPI in 64% and improvement in 83% of subjects. Children with a history of cleft palate had significantly decreased odds of VPI improvement compared to those without a history of cleft palate. Neither syndrome diagnosis nor 22q11 deletion had a significant association with speech outcomes after sphincter pharyngoplasty.

Analysis of velopharyngeal function and speech outcomes of Sommerlad palatoplasty combined with sphincter pharyngoplasty in surgical repair of older patients with cleft palate：experience from a major craniofacial surgery centre in eastern China

We aimed to evaluate velopharyngeal function and speech outcomes of Sommerlad palatoplasty combined with sphincter pharyngoplasty in surgical repair of cleft palate in patients over five years old. Fifty-eight patients were reviewed between the years 2013 and 2017, 31 of whom were treated with Sommerlad palatoplasty combined with sphincter pharyngoplasty, (mean age 15 (range 9 - 22) years), and 27 were treated with Sommerlad palatoplasty alone (mean age 18 (range 10-25) years). Velopharyngeal function was evaluated by radiographic lateral cephalometry and nasoendoscopy. Hypernasality, nasal emissions, and intelligibility were used to assess speech. The rate of velopharyngeal competence was 20/31 in the palatoplasty plus pharyngoplasty group and 7/27 in the palatoplasty alone group after surgical treatment (p=0.003). The improvements in hypernasality (p=0.024), air emission (p=0.004), and speech intelligibility (p=0.004) in the palatoplasty plus pharyngoplasty group was better than that in the palatoplasty alone group. It has been suggested that the surgical approach with the palatoplasty together with the sphincter pharyngoplasty has a higher rate of success in surgical repair of older patients with cleft palate.

The Effectiveness of Palate Re-Repair for Treating Velopharyngeal Insufficiency: A Systematic Review and Meta-Analysis

BACKGROUND

Palate re-repair has been proposed as an effective treatment for velopharyngeal insufficiency (VPI) with a low risk of obstructive sleep apnea (OSA). The authors conducted a systematic review and meta-analysis to determine the proportion of patients achieving normal speech resonance following palate re-repair for VPI, the proportion developing OSA, and the criteria for patient selection that are associated with increased effectiveness.

METHODS

PubMed, Embase, and Scopus were searched from inception through April 2018 for English language articles evaluating palate re-repair for the treatment of VPI in patients with a repaired cleft palate. Inclusion criteria included reporting of hypernasality, nasal air emission, nasometry, additional VPI surgery, and/or OSA outcomes. Meta-analysis was conducted using random effects models. Risk of bias was assessed regarding criteria for patient selection, blinding of outcome assessors, and validity of speech assessment scale.

RESULTS

Eighteen studies met inclusion criteria. The incidence of achieving no consistent hypernasality follow palate re-repair was 61% (95% confidence interval [CI]: 44%-75%). The incidence of additional surgery for persistent VPI symptoms was 21% (95% CI: 12%-33%). The incidence of OSA was 28% (95% CI: 13%-49%). Criteria for selecting patients to undergo re-repair varied, with anterior/sagittal position of palatal muscles (33%) and small velopharyngeal gap (22%) being the most common. No specific patient selection criteria led to superior speech outcomes (P = .6572).

CONCLUSIONS

Palate re-repair achieves normal speech resonance in many but not all patients with VPI. Further research is needed to identify the specific examination and imaging findings that predict successful correction of VPI with re-repair.

Protocols for Reporting Speech Outcomes following Palatoplasty or Velopharyngeal Surgery: A Literature Review

Background:

To determine best practices, surgeons who perform cleft palate surgery or surgery for velopharyngeal insufficiency need to be able to compare their outcomes in normalizing the velopharyngeal valve.

Methods:

We conducted a comprehensive review of articles that reported speech/resonance outcomes following palatoplasty or surgery for velopharyngeal insufficiency. We analyzed protocols that were used and how the results were reported. We found 170 articles, published between 1990 and 2014, that met our inclusion criteria.

Results:

Most studies (66%) had a sample size of <50 subjects, were retrospective (67%), were not blinded (83%), and did not report the use of reliability (68%). Most studies included 1 evaluator (27%) or 2 evaluators (30%). Only 80% of the articles specified that at least one speech pathologist was an evaluator. Most articles (56%) did not specify the speech samples used, and 65% used an informal test or did not specify the type of test used. Most studies used a perceptual rating scale for articulation (75%) and resonance (83%). Only 39% of the studies included an evaluation of velopharyngeal function. Finally, objective measures were used in only 28% of the studies (9% used aerodynamic measures and 19% used nasometry).

Conclusions:

Because these articles showed significant variability in how speech/resonance is evaluated and how the outcomes are reported, it is virtually impossible to compare results to determine best surgical procedures. Suggestions are given to standardize outcome measures to improve comparability of data.

Acquired Velopharyngeal Dysfunction: Survey, Literature Review, and Clinical Recommendations

PURPOSE

The aim of this study was to describe the clinical assessment recommendations for acquired velopharyngeal dysfunction (AVPD) and, through a literature review and online survey, summarize current practice patterns for evaluation and treatment pathway determination for this target population.

METHOD

An online survey to query current assessment procedures and treatment pathway recommendations for AVPD was developed. Following survey results, a literature review was completed to determine evidence-based recommendations for assessment procedures and intervention recommendations based on assessment findings. Literature search terms included the following: acquired velopharyngeal dysfunction, hypernasality, non-cleft velopharyngeal dysfunction, velopharyngeal dysfunction, velopharyngeal dysfunction AND iatrogenic, velopharyngeal dysfunction AND neurogenic, velopharyngeal dysfunction AND assessment OR evaluation, velopharyngeal dysfunction AND treatment OR intervention, velopharyngeal dysfunction AND practice patterns OR clinical guidelines, velopharyngeal insufficiency. Inclusion criteria were limited to practice patterns/recommendations for assessment and/or treatment recommendations for AVPD, English language articles published between 2000 and 2017, and peer-reviewed journals. Studies regarding solely congenital or cleft palate velopharyngeal dysfunction and intervention outcome studies were excluded. Forty articles met inclusionary criteria.

RESULTS

The online survey results indicated lack of consensus for AVPD assessment and treatment recommendation protocols, with 93% of respondents indicating the need for a clinical guide for developing treatment recommendations. The majority of recommendations were filtered into an algorithm for clinical decision making.

CONCLUSIONS

Clinical uncertainty among speech-language pathologists surveyed and the paucity of published clinical guidelines for assessing individuals with AVPD indicate the need for additional clinical research for this disorder, one that is heterogeneous and distinct from those with congenital velopharyngeal dysfunction. The proposed evidence-based clinical worksheet may assist in determining management for patients with AVPD and may serve as a starting place for validation of a clinical guideline.

Outcomes of Sphincter Pharyngoplasty in the Cleft Population

INTRODUCTION

Sphincter pharyngoplasty (SP) is becoming increasingly popular for correction of velopharyngeal insufficiency (VPI) after cleft palate repair because of high success rate, low incidence of postoperative obstructive sleep apnea (OSA), and ease of revision in case of failure. This study is a meta-analysis of SP outcomes, reasons for failure, and revision strategies.

METHODS

A comprehensive review of the literature on SP outcomes was conducted. Sphincter pharyngoplasty failure was defined as persistent hypernasality, incomplete velopharyngeal port (VP) closure on instrumental evaluation with concomitant VPI, or nonresolving hyponasality and/or OSA persisting >3 months after surgery. Two-tailed paired Student t test was used to compare outcomes between syndromic versus nonsyndromic patients and preoperative versus postoperative OSA rates.

RESULTS

Forty-four publications evaluating 2402 patients were included. Overall SP success rate was 78.4% (77.3% in nonsyndromic vs 84.8% in syndromic patients, P = 0.11). Overall primary revision rate was 17.8% (20% in nonsyndromic vs 15.4% in syndromic patients P = 0.97). Most failures (89.5%) manifested as persistent VPI with continued hypernasality requiring revision, whereas 10.5% of failures manifested as obstructive symptoms and/or severe hyponasality requiring revision. Causal factors of SP failure were the following: large central port (62.8%), dehiscence (15.5%), tight port (12.1%), and low-inset (9.7%). Primary revision success rate was 75.6%. Obstructive sleep apnea rates increased from 5.1% to 18.4% (P = 0.02).

CONCLUSIONS

This study suggests that SP can resolve VPI in 78.4% of patients, which can be increased to 94.7% after one revision. Most failures are technique-dependent; therefore, there could be significant ground for improvement of outcomes.

Speech outcomes following Sommerlad primary palatoplasty: Results of the Ghent University Hospital

OBJECTIVE AND SUBJECTS

Speech outcomes were described for 16 patients with cleft palate (mean age: 5.4 years) following Sommerlad primary palatoplasty performed by a single surgeon of the Ghent University Hospital. These speech outcomes were compared with those of an age and gender matched control group without cleft palate (mean age: 5.3 years).

METHODS

Speech intelligibility/distinctiveness, resonance, nasal airflow and articulation, were perceptually evaluated. Additionally, nasalance values and the NSI 2.0 were determined.

RESULTS

In seven patients, speech intelligibility/distinctiveness was disordered. Hypernasality was present in twelve participants, whereas nasal emission and nasal turbulence were perceived in thirteen and five patients respectively. Both perceptual and instrumental speech evaluations were significantly poorer in the patient group in comparison to the control group.

CONCLUSIONS

Patients still present with both obligatory and compensatory speech disorders following Sommerlad's palatoplasty. In the future, a Dutch speech assessment protocol will be developed in order to standardize follow-up of these patients and to allow for within-center and inter-center comparisons.

Superiorly Based Pharyngeal Flap for the Surgical Treatment of Velopharyngeal Insufficiency and Speech Outcomes

A retrospective chart review comparing pre and postoperative speech in 19 patients who underwent pharyngeal flap surgery for the diagnosis of velopharyngeal insufficiency. Eighteen of the patients had a history of cleft palate. Patients were assigned a speech grade between 1 and 5 based on the objective and subjective quality of their speech. Comparison of pre and postoperative speech showed significant improvement in speech quality from a mean grade of 3.37 to 2.00 (P < 0.001). This study demonstrates that a wide, superiorly based pharyngeal flap did lead to significant improvement in speech outcomes in this group of patients independent of gender or age.

Improving speech outcomes after failed palate repair: evaluating the safety and efficacy of conversion Furlow palatoplasty

BACKGROUND

Velopharyngeal insufficiency occurs in a nontrivial number of cases following cleft palate repair. We hypothesize that a conversion Furlow palatoplasty allows for long-term correction of VPI resulting from a failed primary palate repair, obviating the need for pharyngoplasty and its attendant comorbidities.

METHODS

A retrospective review of patients undergoing a conversion Furlow palatoplasty between 2003 and 2010 was performed. Patients were grouped according to the type of preceding palatal repair. Velopharyngeal insufficiency was assessed using Pittsburgh Weighted Speech Scale (PWSS). Scores were recorded and compared preoperatively and postoperatively at 3 sequential visits.

RESULTS

Sixty-two patients met inclusion criteria and were grouped by preceding repair (straight-line repair (n = 37), straight-line repair with subsequent oronasal fistula (n = 14), or pharyngeal flap (n = 11). Median PWSS scores at individual visits were as follows: preoperative = 11, first postoperative = 3 (mean, 114.0 ± 6.7 days), second postoperative = 1 (mean, 529.0 ± 29.1 days), and most recent postoperative = 3 (mean, 1368.6 ± 76.9 days). There was a significant difference between preoperative and postoperative PWSS scores in the entire cohort (P < 0.001) with overall improvement, and post hoc analysis showed improvement between each postoperative visit (P < 0.05) with the exception of the second to the most recent visit. There were no differences between postoperative PWSS scores in the operative subgroupings (P > 0.05). Eight patients failed to improve and showed no differences in PWSS scores over time (P > 0.05). Patients with a PWSS score of 7 or greater (n = 8) at the first postoperative visit (0-6 months) displayed improvement at the most recent visit (P< 0.05).

CONCLUSIONS

Conversion Furlow palatoplasty is an effective means for salvaging speech. Future studies should elucidate which factors predict the success of this technique following failed palate repair.

Change in Quality of Life with Velopharyngeal Insufficiency Surgery

OBJECTIVES

(1) To define the minimal clinically important difference (MCID) of the Velopharyngeal Insufficiency (VPI) Effects on Life Outcomes (VELO) instrument, and (2) to test for the change in quality of life (QOL) after VPI surgery.

STUDY DESIGN

Prospective observational cohort.

SETTING

VPI clinic at a tertiary pediatric medical center.

SUBJECTS AND METHODS

Children with VPI and their parents completed the VELO instrument (higher score is better QOL) at enrollment and then underwent VPI surgery (Furlow palatoplasty or sphincter pharyngoplasty, n = 32), other treatments (obturator or oronasal fistula repair, n = 7), or no treatment (n = 18). They completed the VELO instrument again and an instrument of global rating of change in QOL at 1 year. The MCID was anchored to the global change instrument scores corresponding to "a little" or "somewhat" better. Within-group (paired t test) and between-group (Student t test) changes in VELO scores were tested for the VPI surgery and no treatment groups. The association between treatment group and change in VELO scores was tested with multivariate linear regression, adjusting for confounders.

RESULTS

Follow-up was obtained for 37 of 57 (65%) patients. The mean (±standard deviation) change in VELO scores corresponding to the MCID anchor was 15 ± 13. The VELO score improved significantly more in the VPI surgery group (change, 22 ± 15; P < .001) than in the no treatment group (change, 9 ± 12; P = .04), after adjusting for confounders (P = .007 between groups).

CONCLUSION

VPI surgery using the Furlow palatoplasty or sphincter pharyngoplasty improves VPI-specific QOL, and the improvement is clinically important.

Use of imaging to evaluate course of the carotid artery in surgery for velopharyngeal insufficiency

OBJECTIVE

This study aimed to describe syndromes where preoperative imaging may be essential in determining the course of the carotid arteries before velopharyngeal insufficiency (VPI) surgery and therefore affect surgical planning.

METHODS

Records of children who underwent surgery for VPI between May 1, 2012, and October 30, 2013, at a tertiary care pediatric otolaryngology center were reviewed. Data collected included age at operation, preoperative and postoperative nasometry values, presence of underlying genetic disorders, and imaging findings.

RESULTS

Twenty-five patients underwent 33 surgeries for VPI, with 1 posterior pharyngeal wall augmentation, 6 Furlow palatoplasties, 11 sphincter pharyngoplasties, and 15 pharyngeal flaps. Medialized carotid vasculature was identified in 5 of 25 patients (20%). Seven syndromic patients were identified, with 3 patients having 22q11.2 deletion syndrome. All patients (100%) with 22q11.2 deletion syndrome had medialized carotid arteries. Of the 4 additional syndromic children, 2 (50%) had medial internal carotid arteries, with 1 patient diagnosed with neurofibromatosis 1 and another with Prader-Willi syndrome. Both patients underwent Furlow palatoplasty.

CONCLUSION

Whereas 22q11.2 deletion syndrome is recognized as an entity where a medial carotid is often present, other syndromic children may also demonstrate vascular variability. Although a larger study is needed to confirm an increased prevalence in these patients, clinicians may need a higher degree of suspicion while performing the physical examination. If examination findings are suggestive or the disease process may lend itself to this abnormality, vascular imaging can be considered as part of presurgical planning to help guide surgical technique and prevent complications.

Análise perceptiva e nasométrica da hipernasalidade após a veloplastia intravelar para correção da insuficiência velofaríngea: efeitos a longo prazo

Objetivo investigar o efeito, a longo prazo, da veloplastia intravelar realizada para a correção cirúrgica da insuficiência velofaríngea (IVF) residual, sobre a hipernasalidade de indivíduos com fissura de palato reparada. Métodos foram avaliados 60 pacientes com fissura de palato±lábio operada e IVF residual, de ambos os sexos, com idade entre 4 e 52 anos, os quais foram submetidos à palatoplastia secundária com veloplastia intravelar. A avaliação perceptivo-auditiva da fala foi realizada para classificação da hipernasalidade, durante a conversação espontânea e a repetição de vocábulos e frases, utilizando-se escala de 6 pontos, onde 1=ausência e 6=hipernasalidade grave. A nasometria foi utilizada para determinação do escore de nasalância (correlato acústico da nasalidade), durante a leitura de 5 sentenças contendo sons exclusivamente orais, utilizando-se como limite de normalidade o escore de 27%. As avaliações foram realizadas 4 dias antes e 16 meses, em média, após a cirurgia e o sucesso cirúrgico foi analisado com base na proporção de redução e eliminação/normalização da hipernasalidade e da nasalância. Resultados verificou-se, após a cirurgia, redução da hipernasalidade e da nasalância em 75% e 52% dos pacientes, respectivamente. Proporções menores foram identificadas quando utilizado o critério mais rigoroso de análise (eliminação/normalização), ou seja, 32% de eliminação da hipernasalidade e 38% de normalização da nasalância, respectivamente. Conclusão aveloplastia intravelarmostrou ser um procedimento efetivo, a longo prazo, na redução do sintoma mais significante da IVF residual e deve ser considerada como uma primeira opção no tratamento cirúrgico da IVF residual.

Outcomes of Combined Furlow Palatoplasty and Sphincter Pharyngoplasty for Velopharyngeal Insufficiency

Objective

To compare surgical outcomes between pharyngeal flap, sphincter pharyngoplasty, and combined Furlow palatoplasty and sphincter pharyngoplasty in the management of pediatric velopharyngeal insufficiency.

Study Design

Case series with chart review.

Setting

Tertiary care pediatric hospital.

Subjects and Methods

After exclusion of children with velocardiofacial syndrome, 96 patients who underwent surgical intervention between 2008 and 2012 were identified. Surgical interventions were categorized as pharyngeal flap, sphincter pharyngoplasty, and combined Furlow palatoplasty and sphincter pharyngoplasty. Main outcome measures included perceptual speech analyses, complications, and surgical revision rates.

Results

Of the 96 reviewed patients, 38 (39.6%) underwent pharyngeal flap, 20 (20.8%) sphincter pharyngoplasty, and 38 (39.6%) combined Furlow palatoplasty and sphincter pharyngoplasty. Choice of surgical intervention was based on patient characteristics, observed palatal length, and formal speech assessments. There were no differences in patient demographics or preoperative perceptual speech analysis scores among the 3 surgical groups. The mean speech improvement was significantly greater in both the pharyngeal flap ( P = .031) and combined procedure ( P = .013) compared with sphincter pharyngoplasty alone, but no differences were observed between the pharyngeal flap and combined procedure ( P = .797). There were no differences in complications among the 3 surgical interventions ( P = .220). The combined procedure required significantly less surgical revisions than the pharyngeal flap ( P = .019).

Conclusion

Combined Furlow palatoplasty and sphincter pharyngoplasty is an effective procedure for the management of pediatric velopharyngeal insufficiency and may result in superior speech outcomes and lower revision rates than sphincter pharyngoplasty and pharyngeal flap, respectively.

Validity and responsiveness of VELO: a velopharyngeal insufficiency quality of life measure

OBJECTIVE

Test the Velopharyngeal Insufficiency (VPI) Effects on Life Outcomes (VELO) instrument for validity, reliability, and responsiveness.

STUDY DESIGN

Observational cohort.

SETTING

Academic tertiary medical center.

SUBJECTS

Children with VPI (n = 59) and their parents (n = 84) were prospectively enrolled from a pediatric VPI clinic.

METHODS

Pediatric speech language pathologists diagnosed VPI using perceptual speech analysis and rated VPI severity and speech intelligibility deficit (each as minimal, mild, moderate, or severe). All parents and youth 8+ years old (n = 24) completed the VELO instrument and other quality-of-life questionnaires at baseline; the first 40 subjects completed the VELO instrument again 2 weeks later. Treatments included Furlow palatoplasty (n = 20), sphincter pharyngoplasty (n = 14), or an obturator (n = 2), and 29 of 36 (81%) subjects completed the questionnaires 3 months posttreatment. VELO was tested with correlations for criterion validity against VPI severity, construct validity against speech intelligibility and velopharyngeal gap size, and concurrent validity against other quality-of-life measures (r > .40 demonstrating validity); for test-retest reliability using intraclass correlation (>.6 demonstrating reliability); and for responsiveness with the 3-month posttreatment measure using the paired t test.

RESULTS

Parental responses are reported; youth responses showed similar results. The VELO instrument did not meet criterion validity (r = -.18, P = .10), or functional construct validity (r = -.37, P = .001), but did meet anatomic construct and concurrent validity (each r > .50, P < .01). VELO scores demonstrated excellent test-retest reliability (r = .85, P < .001) and responsiveness (baseline 54 ± 14 to posttreatment 70 ± 18, P < .001).

CONCLUSION

VELO provides a VPI-specific quality-of-life instrument that demonstrates concurrent validity, test-retest reliability, and responsiveness to change in quality of life with treatment.

Velopharyngeal Dysfunction and 22q11.2 Deletion Syndrome: A Longitudinal Study of Functional Outcome and Preoperative Prognostic Factors

Objective

To describe the effect of time after velopharyngoplasty on outcome and to search for preoperative prognostic factors for residual hypernasality in patients with 22q11.2 deletion syndrome.

Design

Retrospective chart review.

Setting

Tertiary hospital.

Patients

Patients with 22q11.2 deletion syndrome and velopharyngeal dysfunction who underwent a primary (modified) Honig velopharyngoplasty between 1989 and 2009.

Main Outcome Measures

Clinically obtained perceptual and instrumental measurements of resonance, nasalance, and understandability before and after velopharyngoplasty.

Results

Data were available for 44 of 54 patients (81% follow-up), with a mean follow-up time of 7.0 years (range, 1.0 to 19.4 years). During follow-up, 24 (55%) patients attained normal resonance and 20 (45%) had residual hypernasality or underwent revision surgery. Mean postoperative nasalance and understandability scores were closer to the norm than mean preoperative scores were (2.0 versus 5.5 standard deviations for the normal passage, 1.3 versus 8.1 standard deviations for the nonnasal passage, and score 2.3 versus 4.1 understandability). Serial measurements revealed that hypernasality only resolved an average of 5 years after surgery, and three patients whose resonance initially normalized later relapsed to hypernasality. Gender, age at surgery, lateral pharyngeal wall adduction, velar elevation, presence of a palatal defect, previous intravelar veloplasty, nasalance, understandability, adenoidectomy, hearing loss, and IQ were not able to predict poor outcome following primary velopharyngoplasty (all p > .05).

Conclusions

In this chart review of patients with 22q11.2 deletion syndrome and velopharyngeal dysfunction, residual hypernasality persisted in many patients after velopharyngoplasty. None of the preoperative factors that were studied had prognostic value for the outcome.

In search of the optimal surgical treatment for velopharyngeal dysfunction in 22q11.2 deletion syndrome: a systematic review

BACKGROUND

Patients with the 22q11.2 deletion syndrome (22qDS) and velopharyngeal dysfunction (VPD) tend to have residual VPD following surgery. This systematic review seeks to determine whether a particular surgical procedure results in superior speech outcome or less morbidity.

METHODOLOGY/ PRINCIPAL FINDINGS

A combined computerized and hand-search yielded 70 studies, of which 27 were deemed relevant for this review, reporting on a total of 525 patients with 22qDS and VPD undergoing surgery for VPD. All studies were levels 2c or 4 evidence. The methodological quality of these studies was assessed using criteria based on the Cochrane Collaboration's tool for assessing risk of bias. Heterogeneous groups of patients were reported on in the studies. The surgical procedure was often tailored to findings on preoperative imaging. Overall, 50% of patients attained normal resonance, 48% attained normal nasal emissions scores, and 83% had understandable speech postoperatively. However, 5% became hyponasal, 1% had obstructive sleep apnea (OSA), and 17% required further surgery. There were no significant differences in speech outcome between patients who underwent a fat injection, Furlow or intravelar veloplasty, pharyngeal flap pharyngoplasty, Honig pharyngoplasty, or sphincter pharyngoplasty or Hynes procedures. There was a trend that a lower percentage of patients attained normal resonance after a fat injection or palatoplasty than after the more obstructive pharyngoplasties (11-18% versus 44-62%, p = 0.08). Only patients who underwent pharyngeal flaps or sphincter pharyngoplasties incurred OSA, yet this was not statistically significantly more often than after other procedures (p = 0.25). More patients who underwent a palatoplasty needed further surgery than those who underwent a pharyngoplasty (50% versus 7-13%, p = 0.03).

CONCLUSIONS/ SIGNIFICANCE

In the heterogeneous group of patients with 22qDS and VPD, a grade C recommendation can be made to minimize the morbidity of further surgery by choosing to perform a pharyngoplasty directly instead of only a palatoplasty.

Efeito da veloplastia intravelar sobre a nasalidade em indivíduos com insuficiência velofaríngea

OBJETIVO: verificar o efeito da palatoplastia secundária realizada com veloplastia intravelar sobre a nasalidade e nasalância dos pacientes com fissura de palato reparada e insuficiência velofaríngea (IVF) e comparar os resultados entre estes pacientes, de acordo com o grau de fechamento velofaríngeo aferido na nasofaringoscopia. MÉTODO: estudo prospectivo com 40 pacientes de ambos os sexos, com idades entre 4 e 48 anos, com fissura de palato reparada e IVF residual, avaliado 3 dias antes e 8 meses após a palatoplastia, em média, divididos em dois grupos: um com 25 pacientes com falhas pequenas (grupo I) e outro com 15 pacientes com falhas médias a grandes (grupo II) no fechamento velofaríngeo. A hipernasalidade foi avaliada perceptivamente e nasalância foi avaliada por meio da nasometria. Diferenças entre grupos e etapas foram consideradas significativas ao nível de 5%. O estudo foi aprovado pelo Comitê de Ética para Pesquisa com Seres Humanos da Instituição. RESULTADOS: após a cirurgia, verificou-se redução da hipernasalidade em 84% dos pacientes do grupo I e em 73% dos pacientes do grupo II. Redução da nasalância foi observada em 52% dos casos do grupo I e em 43% dos pacientes do grupo II. CONCLUSÃO: a palatoplastia secundária com veloplastia intravelar levou à melhora da nasalidade na maioria dos pacientes analisados. Os resultados também demonstraram que a cirurgia foi mais efetiva nos pacientes que apresentavam falhas pequenas no fechamento velofaríngeo.

Videofluoroscopic and nasendoscopic correlates of speech in velopharyngeal dysfunction

OBJECTIVE

To compare videonasendoscopy, lateral videofluoroscopy, and perceptual speech examination in the assessment of velopharyngeal dysfunction.

DESIGN

Retrospective observational.

SETTING

Multidisciplinary cleft palate team at a tertiary academic institution.

PATIENTS, PARTICIPANTS

Patients who had undergone videonasendoscopy and lateral videofluoroscopy for suspected velopharyngeal dysfunction at our center were evaluated. Inclusion required that videonasendoscopy, lateral videofluoroscopy, and the perceptual speech exam were performed on the same day. A total of 88 patients were analyzed.

MAIN OUTCOME MEASURE(S)

Primary outcome measures included percent closure on videonasendoscopy, percent closure on lateral videofluoroscopy, and quantitative scores for hypernasal resonance, nasal emission, and facial grimace. Additional outcome measures included linear and angular anatomic measurements obtained from lateral videofluoroscopy.

RESULTS

Moderately strong correlation was found between closure estimates of videonasendoscopy and lateral videofluoroscopy (ρ = .583; p < .001). Lateral videofluoroscopy estimates of closure averaged 11.7% higher than videonasendoscopy. Closure correlated moderately with overall speech severity (ρ = .304; p = .005); whereas, a stronger correlation was seen with hypernasal resonance (ρ = -.479; p < .001). Patients exhibiting grimace had worse closure than those without (79.1% versus 70.7%; p = .035). Movement angle of the velum and change in genu angle correlated significantly with closure function (ρ = -.304; p = .034 and ρ = -.395; p < .001, respectively).

CONCLUSIONS

Videonasendoscopy and lateral videofluoroscopy closure estimates correlated moderately. Lateral videofluoroscopy tended to give smaller gap estimates. Hypernasal resonance and facial grimace are useful clinical indicators of large gap size. Velar movement angle and change in genu angle were identified as anatomical correlates of closure function.

Rehabilitation of an Edentulous Cleft Lip and Palate Patient with a Soft Palate Defect Using a Bar-Retained, Implant-Supported Speech-Aid Prosthesis: A Clinical Report

Prosthetic rehabilitation of an edentulous cleft lip and palate patient with a combined hard and soft palate defect is a great challenge, due to the lack of retention of the obturator prosthesis as a result of its weight and the inability to obtain a border seal. Dental implants improve the retention, stability, and occlusal function of prostheses when used in carefully selected cleft lip and palate cases. This clinical report presents an edentulous unilateral cleft lip and palate patient who has hard and soft palate defects and an atrophied maxilla, treated with an implant-supported speech-aid prosthesis.
