Abstract
INTRODUCTION Craniofacial microsomia (CFM) is a complex congenital condition primarily affecting the ear, mandible, facial nerve and muscles, and tongue. Individuals with CFM are at increased risk of hearing loss, obstructive sleep apnea, and feeding/swallowing difficulties. The purpose of this scoping review was to summarize evidence pertaining to speech production in CFM. METHOD All articles reporting any characteristic of speech production in CFM were included and screened by two independent reviewers by title, abstract, and full text. Data charting captured details related to study population and design, CFM diagnostic criteria, speech outcome measurement, and key findings. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews checklist guided reporting of results. Our protocol was registered on the Open Science Framework (https://osf.io/npr94/) and published elsewhere. RESULTS Forty-five articles were included in the detailed review. Most articles originated from the United States, were published in the past decade, and utilized case report/series study design. A speech-language pathologist authored 29%. The prevalence of velopharyngeal insufficiency ranged from 19% to 55% among studies. Oral distortion of alveolar and palatal fricatives and affricates primarily characterized articulation errors. Studies identified increased disordered speech and lower intelligibility in adolescents with CFM compared to unaffected peers. Evidence pertaining to phonatory and respiratory speech findings is limited. CONCLUSIONS Evidence supports that individuals with CFM are at increased risk of both velopharyngeal and articulatory speech differences. Additional information is needed to develop speech screening guidelines for children with CFM. Heterogeneity in study design and outcome measurement precludes comparisons across studies.

Abstract
Interdisciplinary teamwork is essential for the rehabilitation of patients with cleft lip and palate, and therefore, the application of treatment techniques for velopharyngeal insufficiency, both surgical and prosthetic, depends on the experience of each rehabilitation team. For this reason, the following study consisting of the cooperation between interdisciplinary cleft lip and palate teams from Chile and Argentina, which succeeded in correcting velopharyngeal insufficiency in an adolescent, initially using a pharyngeal bulb prosthesis and speech therapy, and finally through pharyngeal flap surgery, is presented. This shows that international cooperation is a valuable tool for training, implementation, and follow-up of different treatment techniques for teams in formation.

Abstract
Introduction Compensatory articulations are speech disorders due to the attempt of the individual with cleft palate/velopharyngeal dysfunction to generate intraoral pressure to produce high-pressure consonants. Speech therapy is the indicated intervention for their correction, and an intensive speech therapy meets the facilitating conditions for the correction of glottal stop articulation, which is the most common compensatory articulation. Objective To investigate the influence of an intensive speech therapy program (ISTP) to correct glottal stop articulation in the speech of individuals with cleft palate. Methods Speech recordings of 37 operated cleft palate participants of both genders (mean age = 19 years old) were rated by 3 experienced speech/language pathologists. Their task was to rate the presence and absence of glottal stops in the 6 Brazilian Portuguese occlusive consonants (p, b, t, d, k, g) distributed within several places in 6 sentences. Results Out of the 325 pretherapy target consonants rated with glottal stop, 197 (61%) remained with this error, and 128 (39%) no longer presented it. The comparison of the pre- and posttherapy results showed: a) a statical significance for the p1, p2, p3, p4, t1, k1, k2 and d6 consonants (McNemar test; p < 0.05); b) a statistical significance for the p consonant in relation to the k, b, d, g consonants and for the t consonant in relation to the b, d, and g consonants (chi-squared test; p < 0.05) in the comparison of the proportion improvement among the 6 occlusive consonants. Conclusion The ISTP influenced the correction of glottal stops in the speech of individuals with cleft palate.

Abstract
BACKGROUND Velopharyngeal insufficiency (VPI) often results from palatal shortening or insufficient levator function after cleft palate repair. AIMS To assess the efficacy of palatal re-repair with Z-plasty in treatment of VPI for patients with isolated cleft palate (ICP). METHODS This retrospective analysis comprised 130 consecutive patients who had ICP with VPI that required Z-plasty as secondary surgery between 2008 and 2017. Pre- and post-operative evaluation of velopharyngeal function was done perceptually and instrumentally by Nasometer. RESULTS Median patient age at Z-plasty was 6.8 years (range 3.0-20.1). Of the 130 patients, preoperatively VPI was severe in 73 (56%), mild-to-moderate in 55 (42%), and borderline in 2 (2%). Postoperatively, 105 (81%) of patients achieved adequate (normal or borderline) velopharyngeal competence and 16 (12%) required second operation for residual VPI. The success rate was 84% in nonsyndromic patients, 79% in nonsyndromic Pierre Robin sequence patients, and 58% in syndromic patients. In syndromic children, the speech outcome was significantly worse than in nonsyndromic children (P = 0.014). Complications included wound healing problems in 3 patients (2%), mild infection in 1 patient (1%), postoperative bleeding in 1 (1%), and postoperative fistula in 2 (2%). CONCLUSION Palatal re-repair with Z-plasty is a safe operation for VPI correction in patients with ICP with a success rate of 81%. In syndromic patients, the procedure did not seem to work as well as in nonsyndromic patients.

Abstract
ABSTRACT The surgical management of velopharyngeal incompetence (VPI) in children with 22q11.2 deletion syndrome (22q11.2 DS) is challenging. There are numerous approaches and children often undergo more than one operation. Our aim was to develop a method using images from routine lateral videofluoroscopy to study the dimensions of the velopharynx in this cohort.We analyzed 22 pre-operative lateral videofluoroscopy recordings of children with 22q11.2 DS and VPI. Fourteen had a submucous cleft palate (SMCP) and 8 had no obvious palatal abnormality but who were subsequently labelled as having an occult submucous cleft palate (OSMCP). The control data were 10 historic records of children with cleft lip and an intact palate. The authors identified key points on radiographs of the velum at rest and when elevated to measure the total velar length, functional velar length and pharyngeal depth and compared them ratiometrically.The intra-observer reliability was > 0.9 whereas the inter-observer reliability was > 0.74. The velopharyngeal depth/total velar length was significantly greater in 22q11.2 DS than the control group P < 0.001. There was no difference between SMCP and OSMCP patients, P = 0.556. There was no difference in the functional velar length/total velar length between 22q11.2 DS and controls (P = 0.763).In this study, the authors demonstrate a reliable method to gain useful ratiometric measurements of the velopharynx. This may help with treatment planning. Children with 22q11.2 DS and VPI have a larger velopharyngeal depth/total velar length ratio that may explain some of the difficulty in management.

Abstract
Introduction Individuals with cleft palate can present with velopharyngeal dysfunction after primary palatoplasty and require a secondary treatment due to insufficiency. In these cases, the pharyngeal bulb prosthesis can be used temporarily while awaiting secondary surgery. Objective This study aimed to investigate the outcome of treatment of hypernasality with pharyngeal bulb prosthesis in patients with history of cleft palate presenting with velopharyngeal insufficiency after primary palatal surgery. We hypothesized that the use of the pharyngeal bulb prosthesis is an effective approach to eliminate hypernasality related to velopharyngeal insufficiency in patients with cleft palate. Methods Thirty speakers of Brazilian Portuguese (15 males and 15 females) with operated cleft palate, ages ranging from 6 to 14 years (mean: 9 years; SD = 1.87 years), participated in the study. All patients were fitted with a pharyngeal bulb prosthesis to manage velopharyngeal insufficiency while they were awaiting corrective surgery to be scheduled. Auditory-perceptual analysis of speech recorded in the conditions with and without pharyngeal bulb prosthesis were obtained from three listeners who rated the presence or absence of hypernasality for this study. Results Seventy percent of the patients eliminated hypernasality while employing the pharyngeal bulb prosthesis, while 30% still presented with hypernasality. The comparison was statistically significant (p < 0.001). Conclusion The use of the pharyngeal bulb prosthesis is an effective approach to eliminate hypernasality related to velopharyngeal insufficiency.

Abstract
OBJECTIVES Velopharyngeal insufficiency (VPI) may be due to functional or anatomic causes, and can lead to speech deficits, communication difficulty, and emotional strain on patients and their caregivers. The VPI Effects on Life Outcomes (VELO) instrument quantifies quality of life outcomes in VPI patients both before and after VPI surgery. This study aims to identify pre-operative patient characteristics associated with better post-operative quality of life. METHODS This study is a retrospective chart review of 51 patients who underwent VPI surgery between 2009 and 2018 at a tertiary free-standing children's hospital. A 26-item parent-proxy VELO questionnaire was administered by telephone to parents to assess their child's quality of life post-VPI surgery. RESULTS Twenty-seven parents responded to the VELO questionnaire. Average post-operative VELO score was significantly higher in non-syndromic patients as compared with syndromic patients. Average post-operative VELO score was not significantly different between patients with and without submucous cleft (SMC) or those with mild to moderate versus severe pre-operative hypernasality. On multivariate analysis, absence of genetic syndrome, lack of submucous cleft, and presence of severe-pre-operative hypernasality were significantly and positively associated with increased post-operative VELO scores. CONCLUSION Children who undergo VPI surgery are more likely to have better post-operative quality of life outcomes if their VPI was not associated with a genetic syndrome or submucous cleft. Non-syndromic and non-SMC patients with severe pre-operative hypernasality may benefit significantly from VPI surgery and have improved post-operative quality of life.

Abstract
The objective of this study was to investigate the occurrence of Passavant's ridge in patients with history of cleft palate presenting with velopharyngeal insufficiency (VPI) after primary palatal surgery. Twenty-five adult patients (mean age of 32 years), who wore a pharyngeal bulb prosthesis to correct VPI after primary palatoplasty participated in the study. Presence of Passavant's ridge was investigated in four conditions: prior to pharyngeal bulb for treatment of VPI (C1); during the molding of the pharyngeal bulb (C2); six months after the use of the pharyngeal bulb, but with the prosthesis removed (C3), and six months after the use of the pharyngeal bulb, but with the prosthesis in place (C4). Images of nasoendoscopic assessment of velopharyngeal function were obtained under all conditions were analyzed by speech-pathologists to identify the occurrence of Passavant's ridge during speech production. The results revealed a significant difference between molding condition (C2: 40%) and six months of bulb use (C4: 68%) (p = 0.028). The pharyngeal bulb may elicit the Passavant`s ridge in patients with history of cleft palate presenting with VPI.

Abstract
Objective State-of-the-art activity demands a look back, a look around, and, importantly, a look into the new millennium. The area of speech and language has been an integral part of cleft palate care from the very beginning. This article reviews the development and progression of our knowledge base over the last several decades in the areas of speech; language; anatomy and physiology of the velopharynx; assessment of velopharyngeal function; and treatment, both behavioral and physical, for velopharyngeal problems. Method The clear focus is on the cleft palate condition. However, much of what is reviewed applies to persons with other craniofacial disorders and with other underlying causes of velopharyngeal impairment. A major challenge in the next several years is to sort through speech disorders that have a clear anatomic underpinning, and thus are more amenable to physical management, versus those that may be treated successfully using behavioral approaches. Speech professionals must do a better job of finding and applying ways of treating individuals with less severe velopharyngeal impairment, thus avoiding the need for physical management in these persons or ignoring the speech problem altogether. Conclusion Early and aggressive management for speech and language disorders should be conducted. For most individuals born with cleft conditions, a realistic goal should be normal speech and language usage by the time the child reaches the school-age years.

Abstract
Objective: To compare speech outcomes after operative intervention for velopharyngeal insufficiency between velocardiofacial syndrome patients and nonsyndromic patients. Design: Retrospective cohort study. Setting: Tertiary academic center. Patients: Cohorts of 14 velocardiofacial syndrome and 15 nonsyndromic patients without overt cleft palate who underwent operative procedures to correct velopharyngeal insufficiency. All velocardiofacial syndrome patients were positive for 22q11.2 microdeletion by fluorescent in situ hybridization and possessed phenotypic features of velocardiofacial syndrome. Interventions: Operative procedures, including sphincter pharyngoplasty, Furlow palatoplasty, or both, were selected based on preoperative endoscopic assessments of velopharyngeal motion and residual gap size and shape, as well as velocardiofacial syndrome status. Five single and 9 combined procedures were performed in the velocardiofacial syndrome group, whereas 13 single and 2 combined procedures were performed in the nonsyndromic group. Outcome Measures: Pre- and post-op evaluation was conducted by a speech pathologist. Assessment parameters scored on a numerical scale included speech intelligibility, resonance, nasal air emissions, and overall severity of velopharyngeal insufficiency. Postoperative complications were recorded. Results: Most velocardiofacial syndrome patients and nonsyndromic patients demonstrated significant improvements in all parameters. Comparison of the two groups demonstrated similar improvements in both. Changes in speech resonance were significantly different between the two groups, whereas other speech parameters did not reach significance. There was no difference in airway complications between groups. Conclusions: Velocardiofacial syndrome patients may have comparable outcomes to nonsyndromic patients in selective surgical management of velopharyngeal insufficiency. In addition, the data demonstrate the efficacy of a single-stage combined procedure without increased morbidity.

Abstract
OBJECTIVE: To investigate the incidence of unilateral hypodynamic palate (UHP) and velopharyngeal insufficiency (VPI) in hemifacial microsomia (HFM), and to determine the dysmorphic manifestations having significant associations with UHP/VPI in HFM. STUDY DESIGN: This was a nonrandomized study of 48 patients with unilateral HFM without cleft palate. The correlation between each anomaly and UHP/VPI was analyzed statistically. In addition, we observed 4 HFM patients with cleft palate to examine the influence on cleft palate speech. RESULTS: The incidence of UHP in HFM was 50.0% and that of VPI was 14.6%. All the VPI patients had UHP. Severe micrognathia and soft tissue deficiency, macrostomia, and mental retardation were significant risk factors for developing VPI in HFM. Moreover, UHP exacerbated speech in HFM with cleft lip and palate. CONCLUSIONS: Significant correlations were detected between VPI and HFM. This finding should be helpful in the overall management of HFM. © 2007 American Academy of Otolaryngology-Head and Neck Surgery Foundation. All rights reserved.

Abstract
I report the incidence of hypernasal resonance, nasal emission, and fistula after intravelar surgery with retropositioning of the levator muscle by a single surgeon in a consecutive series of 51 patients who presented with symptomatic submucous cleft palate. Intravelar veloplasty with repositioning of the levator muscle was highly effective in that 37/51 patients (73%) achieved either normal or mild and inconsistent resonance (p<0.0001), and 39 (77%) normal or mild and inconsistent nasal emissions (p<0.0001). The fistula rate was 6% (n=3). Both the clinical grade of submucous cleft palate and the presence of a syndrome correlated directly with changes in hypernasality, whereas the age of the patient and the degree of hypernasality at presentation did not. Non-syndromic patients with clinical grade III and II submucous cleft palates responded well to intravelar surgery with repositioning of the levator muscle, and routine preoperative videofluoroscopy is not recommended. I recommend intravelar surgery with repositioning of the levator muscle routinely for all non-syndromic patients who present with grade III or II submucous cleft palate and velopharyngeal insufficiency.

Abstract
OBJECTIVE Velopharyngeal hypotonia seems to be an important factor in velopharyngeal dysfunction in 22q11.2 deletion syndrome, but the etiology is not understood. Because TBX1 maps within the typical 22q11.2 deletion and Tbx1-deficient mice phenocopy many findings in patients with the 22q11.2 deletion syndrome, TBX1 is considered the major candidate gene in the etiology of these defects. Tbx1 heterozygosity in mice results in abnormal vocalization 7 days postnatally, suggestive of velopharyngeal dysfunction. Previous case-control studies on muscle specimens from patients and mice revealed no evidence for a myogenic cause of velopharyngeal dysfunction. Velopharyngeal muscles are innervated by cranial nerves that receive signals from the nucleus ambiguus in the brainstem. In this study, a possible neurogenic cause underlying velopharyngeal dysfunction in Tbx1 heterozygous mice was explored by determining the size of the nucleus ambiguus in Tbx1 heterozygous and wild type mice. METHODS The cranial motor nuclei in the brainstems of postnatal day 7 wild type (n=4) and Tbx1 heterozygous (n=4) mice were visualized by in situ hybridization on transverse sections to detect Islet-1 mRNA, a transcription factor known to be expressed in motor neurons. The volumes of the nucleus ambiguus were calculated. RESULTS No substantial histological differences were noted between the nucleus ambiguus of the two groups. Tbx1 mutant mice had mean nucleus ambiguus volumes of 4.6 million μm(3) (standard error of the mean 0.9 million μm(3)) and wild type mice had mean volumes of 3.4 million μm(3) (standard error of the mean 0.6 million μm(3)). Neither the difference nor the variance between the means were statistically significant (t-test p=0.30, Levene's test p=0.47, respectively). CONCLUSIONS Based on the histology, there is no difference or variability between the volumes of the nucleus ambiguus of Tbx1 heterozygous and wild type mice. The etiology of velopharyngeal hypotonia and variable speech in children with 22q11.2 deletion syndrome warrants further investigation.

Abstract
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.

Abstract
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.

Abstract
Objective To determine methods by which professionals serving cleft palate/craniofacial teams are evaluating velopharyngeal function and to ascertain what they consider as a successful speech outcome of surgery. Design A 12-question survey was developed for professionals involved in management of velopharyngeal dysfunction. Participants The survey was distributed through E-mail lists for the American Cleft Palate–Craniofacial Association and Division 5 of the American Speech-Language-Hearing Association. Only speech-language pathologists and surgeons were asked to complete the survey. A total of 126 questionnaires were completed online. Results Standard speech evaluations include perceptual evaluation (99.2%), intraoral examination (96.8%), nasopharyngoscopy (59.3%), nasometry (28.9%), videofluoroscopy (19.2%), and aerodynamic measures (4.3%). Significant variation existed in the types and levels of perceptual rating scales. Pharyngeal flap (52.9%) is the most commonly performed procedure for velopharyngeal insufficiency, followed by sphincter pharyngoplasty (27.5%). Criteria for surgical success included normal speech (50.8%), acceptable speech (27.9%), and “improved” speech (8%). However, most respondents felt that success should be defined as normal speech (71.2%). Most respondents believed that surgical success should be determined by the team speech-language pathologist (81.5%); although, some felt success should be determined by the patient/family (17.7%). Conclusion This survey shows considerable variability in the methods for evaluating and reporting speech outcomes following surgery. There is inconsistency in what is considered a successful surgical outcome, making comparison studies impossible. Most respondents thought that success should be defined as normal speech, but this is not happening in current practice.

Abstract
The objective of this study was to describe the process of intensive speech therapy
for a 6-year-old child using compensatory articulations while presenting with
velopharyngeal insufficiency (VPI) and a history of cleft lip and palate. The
correction of VPI was temporarily done with a pharyngeal obturator since the child
presented with very little movement of the pharyngeal walls during speech,
compromising the outcome of a possible pharyngeal flap procedure (pharyngoplasty).
The program of intensive speech therapy involved 3 phases, each for duration of 2
weeks incorporating 2 daily sessions of 50 minutes of therapy. A total of 60 sessions
of intervention were done with the initial goal of eliminating the use of
compensatory articulations. Evaluation before the program indicated the use of
co-productions (coarticulations) of voiceless plosive and fricative sounds with
glottal stops (simultaneous production of 2 places of productions), along with weak
intraoral pressure and hypernasality, all compromising speech intelligibility. To
address place of articulation, strategies to increase intraoral air pressure were
used along with visual, auditory and tactile feedback, emphasizing the therapy target
and the air pressure and airflow during plosive and fricative sound productions.
After the first two phases of the program, oral place of articulation of the targets
were achieved consistently. During the third phase, velopharyngeal closure during
speech was systematically addressed using a bulb reduction program with the objective
of achieving velopharyngeal closure during speech consistently. After the intensive
speech therapy program involving the use of a pharyngeal obturator, we observed
absence of hypernasality and compensatory articulation with improved speech
intelligibility.

Abstract
A child with microdeletion at 22q11.21 was referred to a craniofacial center due to hypernasality, unintelligible speech, and bifid uvula. Velopharyngeal dysfunction remained after surgical repair of submucous cleft palate and speech therapy. A prosthetic-behavioral treatment approach involving total obturation of the velopharynx was successfully implemented for management of velopharyngeal hypodynamism.

Abstract
BACKGROUND Velopharyngeal inadequacy (VPI), which has a significant negative impact on speech intelligibility and resonance quality, may be caused by physiological inadequacy. The current study aimed to investigate the maximal velar and pharyngeal motions and levator muscle shortening in the children with repaired cleft palate and different speech outcomes as well as children without cleft palate by using magnetic resonance imaging techniques without general anesthesia. METHODS Three groups of sex- and age-matched children were recruited: children with repaired cleft palate and adequate velopharyngeal function condition (VPC), children with repaired cleft palate and VPI, and the normal controls (noncleft). The children were trained to perform sustained /a:/, /i:/, /ts:/, and /m:/, while keeping the head still during magnetic resonance imaging scan. The maximal velar elevation and stretch, pharyngeal medial constriction, velopharyngeal ratio (VP ratio), and levator muscle shortening ratio were measured and compared across the 3 groups. RESULTS The VPI group showed the least maximal velar stretch, lowest maximal velar height, smallest maximal pharyngeal constriction, and lowest maximal VP ratio among the 3 groups. The VPI and VPC groups differed significantly in velar and pharyngeal mobility. The effective VP ratio at rest has a strong correlation with that during sustained phonation across the 3 groups. The maximal velar stretch ratio correlates to the maximal pharyngeal constriction ratio strongly in the VPI group only. CONCLUSIONS The VPI group had significantly reduced velar and pharyngeal mobility during speech compared with the VPC and noncleft groups. The possible physiological causes of VPI after primary palatal repair were discussed.

Abstract
INTRODUCTION The straight-line palatoplasty with intravelar veloplasty (IVVP) is one option for cleft palate repair. However, not all IVVPs are performed uniformly. Many IVVPs only address the medialmost portion of the levator muscle, an "incomplete IVVP," failing to completely dissect and adequately transpose the entire levator muscle, "complete IVVP." We believe that for optimal speech results, IVVPs should completely mobilize and posteriorly displace the levator. We propose that a conversion Furlow palatoplasty performed with a "complete IVVP" will correct postoperative velopharyngeal insufficiency (VPI) and alleviate the need for pharyngoplasty. METHODS Nineteen patients with postoperative VPI, having had prior straight-line palatoplasty and reported "IVVP," underwent conversion Furlow palatoplasty. Those with a pre- and postoperative Pittsburgh Weighted Speech Scale (PWSS) value and no other history of palatal surgeries were included in this study. Statistical analysis was performed by using the Wilcoxon signed ranks test. RESULTS Patients' median age was 5.5 years (range, 4-15 years), with 13 males and 7 females. The median preoperative PWSS score was 11.00 (range, 3-24.5), and the median postoperative was 1.00 (range, 0-5) (P < 0.001). All subcategories of the PWSS were also improved. Eight children had a preoperative fistula, and all were successfully corrected. At the time of conversion Furlow palatoplasty, all patients demonstrated no evidence of previous IVVP as the levator muscle was found to be scarred to the posterior edge of the hard palate. CONCLUSION The conversion Furlow palatoplasty can be used to significantly improve VPI and salvage speech after a straight-line palatoplasty with an "incomplete IVVP." Patients with postoperative VPI should first be considered for conversion Furlow palatoplasty performed with a "complete IVVP" prior to progressing to pharyngoplasty.

Abstract
BACKGROUND The objectives of the study were to describe speech outcomes in a large series of patients undergoing Furlow palatoplasty for management of velopharyngeal insufficiency and to test whether preoperative velopharyngeal gap size and other patient characteristics significantly affect those outcomes. METHODS Data collected included age at the time of surgery, surgeon, type of cleft, syndrome diagnosis, preoperative velopharyngeal gap size as determined by videonasendoscopy, and preoperative and postoperative perceptual speech assessments. Descriptive statistics were generated and ordinal logistic regression on the outcome variable, postoperative velopharyngeal insufficiency severity score, was performed. RESULTS In this series of 154 patients, 148 had complete perceptual speech data. Of these 148 patients, 72 percent had improvement in velopharyngeal insufficiency severity after the procedure and 56 percent had complete resolution of velopharyngeal insufficiency. Postoperative insufficiency was scored as none or minimal (i.e., resolution) in 38 of 52 patients (73 percent) with a small preoperative velopharyngeal gap, 26 of 51 patients (51 percent) with a moderate preoperative gap, and four of 21 patients (19 percent) with a large preoperative gap. Preoperative velopharyngeal gap size was significantly associated (p < 0.0001) with postoperative insufficiency on ordinal multivariate logistic regression after controlling for preoperative insufficiency and other covariates. There was not a significant association between syndrome diagnosis, age at Furlow palatoplasty (younger than 5 years versus older), gender, surgeon, or presence of submucous cleft palate and postoperative speech outcome, in either the unadjusted or adjusted analyses. CONCLUSIONS Preoperative velopharyngeal gap size, as determined with nasendoscopy, was significantly associated with postoperative velopharyngeal insufficiency severity after Furlow palatoplasty. Small gap size is associated with a greater likelihood of resolution.

Abstract
OBJECTIVES To analyze the results of surgery for velopharyngeal incompetence (VPI) in velocardiofacial syndrome. DESIGN Prospective data collection, with randomized, blind assessment of speech and velopharyngeal function on lateral videofluoroscopy and nasendoscopy. SETTING Two-site, tertiary referral cleft unit. PATIENTS Forty-two consecutive patients with the 22q11 deletion underwent surgery for symptomatic VPI by a single surgeon. INTERVENTIONS Intraoral examinations, lateral videofluoroscopy (+/- nasendoscopy) and intraoperative evaluation of the position of the velar muscles through the operating microscope. Based on these findings, either a radical dissection and retropositioning of the velar muscles (submucous cleft palate [SMCP repair]) or a Hynes pharyngoplasty (posterior pharyngeal wall augmentation pharyngoplasty) was performed. As anticipated, a proportion of patients undergoing SMCP repair subsequently required a Hynes. The aim of this staged approach was to maximize velar function, thereby enabling a less obstructive pharyngoplasty to be performed. Thus, there were three surgical groups for analysis: SMCP alone, Hynes alone, and SMCP+Hynes. MAIN OUTCOME MEASURES Blind perceptual rating of resonance and nasal airflow; blind assessment of velopharyngeal function on lateral videofluoroscopy and nasendoscopy; and identification of predictive factors. RESULTS Significant improvement in hypernasality in all three groups. The SMCP+Hynes group also showed significant improvement in nasal emission. There were significant improvements in the extended and resting velar lengths following SMCP repair and a trend toward increased velocity of closure. CONCLUSIONS Depending on velopharyngeal anatomy and function, there is a role for SMCP repair, Hynes pharyngoplasty, and a staged combination of SMCP+Hynes, all of which are procedures with a low morbidity.

Abstract
Several interventions are available for management of VPD. Using an approach of differential management based on differential diagnosis, VPD can be effectively treated in most patients. The current challenge for the VPD care team, however, is to resolve the signs and symptoms of VPD without exchanging them for a different but an equally or more morbid set of signs and symptoms.

Abstract
A single surgeon's 20 year experience in one cleft center with differential diagnosis for differential management of velopharyngeal dysfunction (VPD) is reviewed. The specific diagnostic and functional status of each affected individual is determined to select the method of VPD management. Two types of diagnostic evaluation of velopharyngeal function, perceptual and instrumental, are used to make that determination. There are four broad etiologic categories of VPD: anatomic deficiency, myoneural deficiency, anatomic and myoneural deficiency, and neither anatomical nor myoneural deficiency. The type of VPD management is specific for each etiologic category. The management options are between prosthetic appliances (lift, obturator, "liftorator") and operations (intravelar veloplasty, velar Z-plasty, pharyngeal flap, sphincter pharyngoplasty, posterior pharyngeal wall augmentation). The objective of differential management based on differential diagnosis is to optimize the function of the velopharynx for speech tasks while minimizing the morbidity of the intervention on the upper airway. A personal experience, in the context of an interdisciplinary cleft team, with such an approach over the past 20 years validates the assumption that differential management of VPD based on differential diagnosis can achieve this goal.

Abstract
BACKGROUND Resection of skull base tumors commonly necessitates intraoperative sacrifice of lower cranial nerves at the level of the jugular foramen. Sequelae of unilateral vagus nerve loss include ipsilateral laryngeal paralysis, ipsilateral palatal and pharyngeal paralysis, and velopharyngeal incompetence (VPI) marked by hypernasal speech and nasopharyngeal reflux of liquids during swallowing. METHODS Palatal adhesion (PA), a procedure whereby the unilaterally paralyzed palate is attached to the posterior pharyngeal wall, decreases the size of the velopharyngeal port and minimizes the symptoms. This study assessed the outcome of PA in 31 patients with VPI secondary to proximal vagus nerve injury. RESULTS PA decreased postoperative nasality in 96% of patients. Nasopharyngeal reflux was significantly improved in 83%. Three patients (11%) had minor wound breakdown postoperatively, all of which healed completely with conservative management. CONCLUSION PA offers a favorable result with minimal concomitant morbidity and is recommended for patients with VPI secondary to unilateral proximal vagus nerve paralysis.

Abstract
STATEMENT OF PROBLEM When surgical treatment is not considered an option, prosthetic management of velopharyngeal insufficiency is carried out by means of a speech-aid prosthesis, whereas velopharyngeal incompetence is traditionally managed by a palatal lift prosthesis. Varying degrees of treatment success have been attributed to palatal lift prostheses. PURPOSE This study introduces the use of nasopharyngeal obturation instead of palatal elevation for the management of velopharyngeal incompetence. METHODS Seven patients afflicted by neurogenic velopharyngeal incompetence were treated with wire-extension speech-aid prostheses constructed to circumvent the dysfunctional soft palate. The shape of the nasopharyngeal section was functionally molded in speech and swallowing and controlled by video-nasopharyngoscopic examinations. RESULTS Effective nasopharyngeal obturation with notable improved speech was achieved in all patients. Even though all patients ultimately tolerated the prostheses well, 2 patients denied any improvement in speech with the finalized prostheses. CONCLUSION Wire-extension speech-aid prostheses used by the patients were an effective treatment approach for velopharyngeal incompetence. Nasopharyngoscopic control is mandatory for maximizing the effect of velopharyngeal closure around the nasopharyngeal section of the prosthesis in function, yet it allows free nasal breathing. Velopharyngeally incompetent patients should be carefully tailored for prosthetic treatment because of contingent noncompliance.

Abstract
There are no reports in the literature that document the effectiveness of sphincter pharyngoplasty as a surgical alternative to pharyngeal flap for management of velopharyngeal dysfunction in patients with velocardiofacial syndrome. A retrospective review of patients with velocardiofacial syndrome was undertaken at our tertiary cleft care centre. All patients were managed between 1984 and 1996 at the Cleft Palate and Craniofacial Deformities Institute, St Louis Children's Hospital. Subjects (n = 19) underwent velopharyngeal surgical management on the basis of perceptual speech evaluations and instrumental assessments of inadequate velopharyngeal closure. All patients had a molecular diagnosis of velocardiofacial syndrome based on fluorescent in situ hybridisation analysis of peripheral blood lymphocytes and independent evaluation by a medical geneticist. Surgical outcome was classified as successful if perceptual speech assessment indicated elimination of hypernasality, nasal emission and turbulence, and instrumental assessment indicated 100% velopharyngeal closure. Results showed that 18 of 19 patients were managed successfully with sphincter pharyngoplasty. Our data corroborate that sphincter pharyngoplasty is a reasonable alternative to pharyngeal flap in patients with velopharyngeal dysfunction secondary to velocardiofacial syndrome.

Abstract
Velopharyngeal insufficiency (VPI) can be treated surgically with various operations. This article describes the use of a superiorly based folded pharyngeal flap for posterior wall augmentation to treat VPI. This is a retrospective study indicating that a folded flap to augment the posterior wall is likely to be as effective as other surgical techniques to treat small velopharyngeal gaps. Patients selected for this procedure had very good velar motion. Postoperative nasometric zoo passage scores improved by an average of 18 over preoperative scores. Additionally, a correlation was found between age and nasometry improvement after surgery. Younger patients did better. Patients in whom VPI was caused by adenoidectomy did well. The 2 syndromic patients did not do as well when treated with this type of operation.

Abstract
OBJECTIVE This paper reports on the rates of failure of operations (pharyngeal flap and sphincter pharyngoplasty) performed for management of velopharyngeal dysfunction, and outcome following their revision. DESIGN Anatomic abnormalities associated with unacceptable vocal resonance and nasal air escape following pharyngeal flap and sphincter pharyngoplasty were critiqued. The results of primary pharyngeal flap were evaluated for 65 patients, and the results of primary sphincter pharyngoplasty were evaluated for 123 patients. All patients were treated for velopharyngeal dysfunction. The definition of surgical failure was based on persistent hypernasality and/or nasal turbulence on perceptual speech evaluation, and incomplete velopharyngeal closure on instrumental evaluation, at least 3 months postoperatively. SETTING All patients were evaluated and managed at the Cleft Palate and Craniofacial Deformities Institute, St. Louis Children's Hospital, a tertiary cleft care center. PATIENTS, PARTICIPANTS All patients had failed surgical management initially, either with pharyngeal flap or sphincter pharyngoplasty, and all underwent repeat preoperative and postoperative perceptual speech evaluations; real-time lateral phonation fluoroscopy including still reference views; and flexible nasendoscopy of the velopharynx using standard speech protocols. INTERVENTIONS Revisional surgery for both procedures consisted of either tightening of the sphincter pharyngoplasty or pharyngeal flap port(s) or reinsertion of the sphincter pharyngoplasty or pharyngeal flaps following dehiscence. MAIN OUTCOME MEASURES The main outcome measure was normalcy of velopharyngeal function, i.e., elimination of perceptual hypernasality and instrumental evidence of complete velopharyngeal closure. The rates of pharyngeal flap failure and sphincter pharyngoplasty failure were determined for those patients requiring surgical revision. RESULTS Thirteen of 65 patients (20%) who underwent primary pharyngeal flap required revisional surgery. Of these 13 patients, eight were managed successfully with a single revisional operation. The remaining five patients (38%) continued to exhibit velopharyngeal dysfunction and underwent a second revision consisting of tightening or augmentation of the lateral ports. Speech results were satisfactory in all patients so treated; however, hyponasality with no other airway morbidity occurred in all five. Twenty of 123 patients (16%) who underwent primary sphincter pharyngoplasty required surgical revision. Of these 20 patients, 17 were managed successfully. For both procedures, the principal cause of failure was partial or complete flap dehiscence. CONCLUSIONS Rates of primary pharyngeal flap failure are roughly equivalent to rates of primary sphincter pharyngoplasty failure. Pharyngeal flap and sphincter pharyngoplasty failures can be salvaged with revisional surgery, which can provide a velopharyngeal mechanism capable of complete closure. Revisional surgery is usually associated with denasal speech.

Abstract
This outcome study was a continuation of a previously published review. It examined whether there had been a decrease in the number of acute perioperative complications surrounding superior pharyngeal flap operations since a patient's death in 1990. A total of 386 patients were divided into two groups: the early group (July of 1985 to December of 1990) n = 164, and the later group (January of 1991 to June of 1996) n = 222, which were statistically comparable. The patient complication rate decreased from 19.5 to 6.3 percent (chi square, p = 0.0001). Airway obstruction decreased from 11 to 3.2 percent (chi square, p = 0.0012). Bleeding complications decreased from 7.3 to 1.4 percent (chi square, p = 0.0027). The majority of airway complications (72 percent) and bleeding complications (80 percent) occurred in the first 24 hours. Predictive factors for complications included the surgeon involved, patients with associated medical conditions, having an associated procedure performed concurrently, and leaving the donor site open (multiple logistic regression). Hospital stay also decreased from 5.8 +/- 2.5 to 3.8 +/- 1.6 days (Student's t test p = 0.0001). The decrease in complication rate was due to the increased awareness of all staff involved and also due to changes in surgical management, including a decrease in the number of surgeons (from seven to four surgeons), a decrease in the number of associated procedures (10.4 to 4.5 percent, chi square, p = 0.026), a decrease in the number of open donor sites (34.8 to 4.5 percent, chi square, p = 0), and an increase in the use of nasopharyngeal airways (17.1 to 45 percent, chi square, p = 0). The superior pharyngeal flap operation has become a safer procedure in this hospital.

Abstract
This report describes postoperative airway compromise following sphincter pharyngoplasty (SP) for treatment of post-palatoplasty velopharyngeal dysfunction. A retrospective review of 58 SPs performed for post-palatoplasty velopharyngeal dysfunction, on 30 male, and 28 female patients, over a 5-year study period was undertaken at a tertiary referral academic institution (Washington University School of Medicine), at the St. Louis Children's Hospital, Cleft Palate and Craniofacial Deformities Institute. Eight patients were identified who had the following inclusion criteria: overt perioperative and/or postoperative airway dysfunction, identifiable syndromes, or microretrognathia. Items reviewed were patient demographic factors, associated medical problems, genetics evaluations, nasendoscopic characteristics of velopharyngeal closure, anesthetic evaluation of the patients, and the incidence and severity of perioperative complications. Particular attention was paid to factors contributing to the airway obstruction. Of the eight subjects with perioperative and/or postoperative upper airway dysfunction following SP, five patients had Pierre Robin sequence/micrognathia, while three patients had a history of perinatal respiratory and/or feeding difficulties without micrognathia or an identified genetic disorder. All but two episodes of airway dysfunction resolved within 3 days postoperatively. These patients were discharged home with apnea monitors; both were readmitted with recurrent airway dysfunction. Continuous positive airway pressure (CPAP) was utilized successfully in all instances, and no patients required take-down of the SP to relieve airway dysfunction. CPAP is an effective, noninvasive treatment strategy for management of iatrogenically induced apnea following SP, without sacrificing the surgical benefit of improved speech intelligibility.

Abstract
The purpose of this investigation was to evaluate the ability of palatal lift prostheses to stimulate the neuromuscular activity of the velopharynx. Nasendoscopic evaluations were audio-videotaped preprosthetic and postprosthetic management for 25 patients who underwent placement of a palatal lift prosthesis for velopharyngeal dysfunction (VPD). These audio-videotapes were presented in blinded fashion and random order to three speech pathologists experienced in assessment of patients with VPD. They rated the tapes on the following parameters: VP gap size, closure pattern, orifice estimate, direction and magnitude of change, and qualitative descriptions of the adequacy of VP closure during speech. VP closure for speech was unchanged in 69% of patients and the number of patients rated as improved or deteriorated was nearly identical at about 15%. Postintervention gap shape remained unchanged in 70% of patients. The extent of VP orifice closure during speech remained unchanged in 57% of patients. Articulations that could impair VP function improved in 30% of patients, deteriorating in only 4%. Results of this study neither support the concept that palatal lift prostheses alter the neuromuscular patterning of the velopharynx, nor provide objective documentation of the feasibility of prosthetic reduction for weaning.
