Impact of Anatomical Abnormalities on Velopharyngeal Insufficiency in Patients with Submucous Cleft Palate

BackgroundSubmucous cleft palate (SMCP) is a congenital anomaly characterized by Calnan's triad. However, in clinical practice, it is common forindividuals to exhibit one or two anatomical abnormalities within the triad. Furthermore, the definition of SMCP has been diverse and ambiguous in previous studies. Therefore, this study aimed to analyze the correlation between anatomical abnormalities and development of velopharyngeal insufficiency (VPI). MethodsWe conducted a retrospective analysis of 99 patients referred to our clinic for speech issues or anatomical abnormalities identified during routine oral examinations from January 2012 to June 2023. A single surgeon performed all physical examinations. We evaluated the presence of a bony notch, zona pellucida, and bifid uvula, assigning a score to each, and analyzed their correlation with VPI. The correlation with each of the abnormalities for VPI was examined, along with the relationship between the number of abnormalities and VPI. ResultsOf the 99 patients, 27 were diagnosed with VPI. Only the bony notch had a significant correlation with the development of VPI. The incidence of VPI tended to increase with the presence of more anatomical abnormalities. VPI occurred in approximately 40% of patients exhibiting all three anatomical abnormalities. ConclusionThe study findings highlight the importance of meticulous intraoral examinations in SMCP patients and careful monitoring in patients with a bony notch or two or more anatomical abnormalities.

Effectiveness of secondary furlow palatoplasty with buccal myomucosal flap in correction of velopharyngeal insufficiency in patients with cleft palate

ObjectivesThe main purpose of this study was evaluation of the effectiveness of secondary furlow palatoplasty with buccal myomucosal flap (FPBF) for the treatment of velopharyngeal insufficiency (VPI) in patients with a cleft palate who were treated with two flap palatoplasty (TFP) in their primary palate repair.Material and methodsTwenty-three medically free children aged 4–8 years with non-syndromic and previously repaired cleft palate via TFP participated in the study. All patients received secondary surgery following the technique of FPBF. Preoperative speech evaluation was done before the secondary repair and 3 months after the surgery using a hypernasal speech scale, speech intelligibility scale, and nasopharyngoscopy.ResultsA statistically significant improvement was observed regarding the degree of hypernasality and speech intelligibility while comparing the preoperative scores after the primary surgery to the postoperative scores after the secondary surgery.In addition, a statistically significant improvement was found in the nasopharyngoscopic assessment.ConclusionsThe incorporation of a buccal myomucosal flap with Furlow palatoplasty was successful in improving hypernasality, speech intelligibility, and nasopharyngoscopic scores in patients with cleft palate.Trial registrationclinicaltrials.gov (NCT05626933).Clinical relevanceThis technique might be the surgical technique of choice while treating patients who are suffering from VPI after cleft palate repair.

Diagnosing and Managing Velopharyngeal Insufficiency in Patients With Cleft Palate After Primary Palatoplasty

Velopharyngeal insufficiency (VPI) after palatoplasty is caused by improper anatomy preventing velopharyngeal closure and manifests as a hypernasal resonance, audible nasal emissions, weak pressure consonants, compensatory articulation, reduced speech loudness, and nostril or facial grimacing. A multidisciplinary team using multimodal instruments (speech analysis, nasoendoscopy, videofluoroscopy, nasometry, and magnetic resonance imaging) to evaluate velopharyngeal function should manage these patients. Careful monitoring of velopharyngeal function by a speech pathologist remains paramount for early identification of VPI and the perceptual assessment should follow a standardized protocol. The greatest methodology problem in CLP studies has been the use of highly variable speech samples making comparison of published results impossible. It is hoped that ongoing international collaborative efforts to standardize procedures for collection and analysis of perceptual data will help this issue. Speech therapy is the mainstay treatment for velopharyngeal mislearning and compensatory articulation, but it cannot improve hypernasality, nasal emissions, or weak pressure consonants, and surgery is the definitive treatment for VPI. Although many surgical methods are available, there is no conclusive data to guide procedure choice. The goal of this review article is to present a review of established diagnostic and management techniques of VPI.

Automatic Detection System for Velopharyngeal Insufficiency Based on Acoustic Signals from Nasal and Oral Channels.

Velopharyngeal insufficiency (VPI) is a type of pharyngeal function dysfunction that causes speech impairment and swallowing disorder. Speech therapists play a key role on the diagnosis and treatment of speech disorders. However, there is a worldwide shortage of experienced speech therapists. Artificial intelligence-based computer-aided diagnosing technology could be a solution for this. This paper proposes an automatic system for VPI detection at the subject level. It is a non-invasive and convenient approach for VPI diagnosis. Based on the principle of impaired articulation of VPI patients, nasal- and oral-channel acoustic signals are collected as raw data. The system integrates the symptom discriminant results at the phoneme level. For consonants, relative prominent frequency description and relative frequency distribution features are proposed to discriminate nasal air emission caused by VPI. For hypernasality-sensitive vowels, a cross-attention residual Siamese network (CARS-Net) is proposed to perform automatic VPI/non-VPI classification at the phoneme level. CARS-Net embeds a cross-attention module between the two branches to improve the VPI/non-VPI classification model for vowels. We validate the proposed system on a self-built dataset, and the accuracy reaches 98.52%. This provides possibilities for implementing automatic VPI diagnosis.

Pharyngeal Flap Versus Sphincter Pharyngoplasty for the Treatment of Velopharyngeal Insufficiency in 22q11.2 Deletion Syndrome: Preliminary Findings From a Systematic Review.

The purpose of this study was to examine and compare surgical and speech outcomes of the posterior pharyngeal flap and sphincter pharyngoplasty following surgical management of velopharyngeal insufficiency in patients with 22q11.2 deletion syndrome (22q11.2DS). This systematic review followed the Preferred Reporting Items for Systematic Review and Meta-Analyses checklist and guidelines. Selected studies were chosen using a 3-step screening process. The 2 primary outcomes of interest were speech improvement and surgical complications. Preliminary findings based on included studies suggest a slightly higher rate of postoperative complications with the posterior pharyngeal flap in patients with 22q11.2DS but a lower percentage of patients needing additional surgery compared with the sphincter pharyngoplasty group. The most reported postoperative complication was obstructive sleep apnea. Results from this study provide some insight into speech and surgical outcomes following pharyngeal flap and sphincter pharyngoplasty in patients with 22q11.2DS. However, these results should be interpreted with caution due to inconsistencies in speech methodology and lack of detail regarding surgical technique in the current literature. There is a significant need for standardization of speech assessments and outcomes to help optimize surgical management of velopharyngeal insufficiency in individuals with 22q11.2DS.

Overlapping Intravelar Veloplasty Improves the Speech Outcomes in Submucous Cleft Palate.

Submucous cleft palate (SMCP) is a subgroup of cleft palate that can present as velopharyngeal insufficiency due to muscle displacement. The pharyngeal flap and Furlow palatoplasty have been introduced to correct SMCP patient with velopharyngeal insufficiency. However, pharyngeal flap and Furlow palatoplasty can occur various complications. We consider the overlapping intravelar veloplasty (IVVP) can overcome these complications. Therefore, we present the speech outcomes of overlapping IVVP for the treatment of patients with SMCP. We retrospectively reviewed 12 patients with SMCP underwent overlapping IVVP between April 2016 and October 2018. The patients who underwent speech evaluation, nasometry, and nasoendoscopy before and after surgery and who were followed up for >18 months were enrolled in this study. The average age of the patients was 5 years (range, 3-11 years) and the postoperative follow-up period ranged from 18 to 24 months (mean, 20 months). The preoperative perceptual speech evaluation was moderate and the postoperative evaluation was normal ( P < 0.01). The preoperative and postoperative nasalance scores obtained using a nasometer were 37.00 and 12.50, respectively, ( P < 0.01). Preoperative and postoperative velopharyngeal movements were grades 3 and 0, respectively, ( P < 0.01). Our study showed that overlapping IVVP could provide successful correction of velopharyngeal insufficiency in patients with SMCP, including relatively old patients.

Subjective and Objective Evaluation of Speech in Adult Patients With Repaired Cleft Palate.

To explore the speech outcomes of adult patients with repaired cleft palate through subjective perception evaluation and objective acoustic analysis, and to compare the differences in pronunciation characteristics between speakers with complete velopharyngeal closure (VPC) and velopharyngeal insufficiency (VPI) patients. Subjective evaluation indicators included speech intelligibility, nasality and consonant missing rate, for objective acoustic analysis, we used speech sample normalization and objective acoustic parameters included normalized vowel formants, voice onset time and the analysis of 3-dimensional spectrogram and spectrum, were carried out on speech samples produced by 3 groups of speakers: (a) speakers with velopharyngeal competence after palatorrhaphy (n=38); (b) speakers with velopharyngeal incompetence after palatorrhaphy (n=70), (c) adult patients with cleft palate (n=65) and (d) typical speakers (n=30). There was a highly negative correlation between VPC grade and speech intelligibility (ρ=-0.933), and a highly positive correlation between VPC and nasality (ρ=0.813). In subjective evaluation, the speech level of VPI patients was significantly lower than that of VPC patients and normal adults. Although the nasality and consonant loss rate of VPC patients were significantly higher than that of normal adults, the speech intelligibility of VPC patients was not significantly different from that of normal adults. In acoustic analysis, patients with VPI still performed poorly compared with patients with VPC. The speech function of adult cleft palate patients is affected by abnormal palatal structure and bad pronunciation habits. In subjective evaluation, there was no significant difference in speech level between VPC patients and normal adults, whereas there was significant difference between VPI patients and normal adults. The acoustic parameters were different between the 2 groups after cleft palate repair. The condition of palatopharyngeal closure after cleft palate can affect the patient's speech.

How Early Can We Predict the Need for VPI Surgery?

This retrospective study reviewed documentation of children with moderate-to-severe VPI at age 3 years who did not undergo VPI surgery until age 5 years. Based on the national cleft register, 959 patients with syndromic and nonsyndromic CP were treated by the craniofacial team at Helsinki University Hospital, Finland between 2000 and 2014. Eighty-six patients fulfilled the study inclusion criteria. The speech pathologist evaluated velopharyngeal function at age 3, 5, and 8 years. Of the 86 children presenting with moderate-to-severe VPI at age 3 years, 94% still had moderate-to-severe VPI at age 5 years, even though speech therapy was offered to 77%. Of those whose velopharyngeal function improved by age 5 years, function regressed to incompetent over time. Overall, 93% underwent VPI surgery and 82% underwent VPI surgery between ages 5 and 8 years. Only 23% at age 8 years still had moderate-to-severe VPI. Speech therapy alone did not improve VPI speech characteristics. Moderate-to-severe VPI did not improve from 3 to 5 years or improved but subsequently relapsed. This suggests that the decision for VPI surgery can be made for children aged 3 years with moderate-to-severe VPI.

What Technique Results in the Lowest Rate of Velopharyngeal Insufficiency in Patients With Submucous Cleft Palate? A Systematic Review and Meta-Analysis.

Objective: To determine which surgical technique offers the lowest rate of velopharyngeal insufficiency (VPI) without the need for further operative intervention, in pediatric patients with nonsyndromic submucous cleft palate (SMCP). Methods: This systematic review and meta-analysis included articles reporting on nonsyndromic pediatric patients treated surgically during childhood for SMCP, with data on postoperative speech outcomes and/or recommendations for secondary surgery. Main outcome measures included rates of unfavorable speech outcomes defined as persistent VPI requiring secondary surgery and speech outcome data. Results: 15 articles met our inclusion criteria, reporting on 383 children who underwent surgical treatment; 343 patients were included in studies reporting recommendations for secondary surgery. There was 1 randomized comparative trial, 4 comparative studies, and 10 single cohort studies. Eight articles used validated speech assessment tools. Our model showed the proportion of patients recommended for secondary surgery varied between techniques, ranging from 0.0% (CI 0.0, 1000) in pharyngeal flap to 17.8% (CI 8.9, 32.5) in straight line repair techniques, but there was no statistically significant difference between treatments (P = .33). Speech improvement ranged from 44.4% to 100%, with 9 studies recommending secondary surgery for some of their patient series. Conclusions: Although not of statistical significance, pharyngeal flap yields the lowest rate of reoperation as a primary technique for pediatric patients with nonsyndromic SMCP. Delayed repair age inherent to SMCP may render operations that rely on a functional levator muscle with less favorable outcomes. The absence of standardized surgical techniques, speech outcomes, speech therapy, and assessment make comparative analysis and recommendation difficult. We advocate for standardized speech assessment tools to improve future quantitative assessment of cleft surgery outcomes and a randomized controlled trial to better elucidate the preferred first-line technique.

Posterior pharyngeal wall augmentation using autologous tiered costal cartilage for velopharyngeal insufficiency

The aim of this study was to retrospectively estimate intervention outcomes and to establish suitable indications for autogenous tiered cartilage augmentation (ATCA) of the posterior pharyngeal wall for velopharyngeal insufficiency (VPI). The sample cohort comprised 17 consecutive patients with VPI (10 boys, 7 girls), excluding syndromic cases. Pre- and postoperative findings were comprehensively evaluated using a combination of speech assessment and lateral pharyngography (LPG). Hypernasality and consonant distortion were scored (normal: 0; mild: 1; moderate: 2; severe: 3). Velopharyngeal gap size at rest (AC) and at maximum closure (BC) were measured on LPG. All patients displayed improvements in velopharyngeal function and speech score, and no patients required re-operation. Pre- and postoperative hypernasality scores were 1.9±0.5 and 0.6±0.5, respectively (P < .001). Pre- and postoperative consonant distortion scores were 1.9±0.6 and 0.6±0.5, respectively (P < .001). Pre- and postoperative AC distances were 8.2±3.4mm and 5.9±2.6mm, respectively (P < .001). Pre- and postoperative BC distances were 3.9±2.4mm and 0.3±0.8mm, respectively (P < .001). Conclusions: ATCA appears effective for surgical treatment of VPI patients with a gap less than 10mm.

Pharyngoplasty versus buccinator myomucosal flap in the management of velopharyngeal-insufficiency coronal pattern of closure

Background Velopharyngeal insufficiency (VPI) is an anatomical or structural defect that hinders sufficient velopharyngeal closure, as visualized on nasoendoscopy. Aim The aim of this work was to compare the result of sphincter pharygoplasty versus buccinator myomucosal flap in management of VPI cases with coronal pattern of closure in order to select the proper operation for managing these cases. Patients and methods This study included 20 patients in our institute with residual VPI after primary repair of cleft palate with age range between 3 and 12 years. Randomly, patients with coronal pattern of closure were categorized into two groups: (A) 10 patients underwent sphincteroplasty and (B) 10 patients underwent buccinator myomucosal flap. Preoperatively and 2 months after operation, every patient was evaluated by auditory perceptual assessment, flexible nasopharyngoscopy, and nasometry. The results were documented, tabulated, and statistically analyzed. Results There were statistically significant improvements of auditory perceptual assessment in obligatory speech disorders and intelligibility of speech, nasometeric evaluation in oral and nasal sentences in both groups. Additionally, there were significant improvements of nasoendoscopic evaluations in the degree of velar movement, presence or absence and size of persistent gap in both groups, and in the degree of lateral pharyngeal wall movements in group A. Conclusion Sphincterpharyngoplasty or buccinator myomucosal flap have satisfactory results in treatment of VPI patients with coronal pattern of closure with no statistically significant difference between both groups.

Treatment of velopharingeal insuffitiency with turn over mucoperiosteal palatinal flap in a patient with DiGeorge syndrome

Introduction. DiGeorge syndrome (velocardiofacial syndrome) occurs in about 1 in 4,000 people. It is characterized by incomplete gene penetration, due to which there is significant variability in the clinical picture in different patients. The paper describes the successful application of an inverted mucoperiosteal flap of the palate in a nine-year-old girl with DiGeorge syndrome who had pronounced velopharyngeal insufficiency (VPI). Case report. The girl was the first-born child from a normal pregnancy and a normal birth with a normal early psychomotor development. During breastfeeding, milk was occasionally returned to the nose, and later deviations from normal speech (incomprehensible and nasal speech) were noticed. At the age of 4, detailed genetic testing was performed and a microdeletion of 22q11 chromosome was found. Also, a submucosal cleft palate was established, and magnetic resonance angiography of the head and neck revealed an abnormal position of the left internal carotid artery (ICA) that extended submucosally to the central axis of the posterior wall of the pharynx. Then, the submucosal cleft palate was surgically resolved in other clinical center, but without speech improvement. Pharyngoplasty was not performed due to the risk of serious post-operative complications. It was explained to the parents that speech recovery will not be satisfactory without surgical treatment of VPI. At the age of 9, the girl was admitted to the Clinic for Plastic and Reconstructive Surgery and Burns of the Military Medical Academy in Belgrade for surgical treatment of VPI. Taking into account the potential risks of certain surgical methods, it was decided to perform intravelar veloplasty according to Furlow. Since it was intraoperatively found that the soft palate is too short and that this procedure cannot provide its sufficient length, the mucoperiosteal flap was lifted from the palate to the palatal aponeuroses on the posterior edges of the palatine bones leaving their oral surfaces exposed. The mucoperiosteal flap raised in this way could not also provide the required length of the soft palate only by retroposition. However, its length is 160% of the soft palate axis length, which was enough to turn over the front of the flap towards the pharynx of the soft palate to reach its posterior wall. The raised mucoperiosteal palatal flap has no muscles, so its motility was achieved by the fact that along the edges of the existing short and mobile palate, the flap was fixed to the existing palate and uvula. This provided the anatomical preconditions for speech recovery, shown during the one-year post-operative follow-up of the child. Exposed palatine bones and short palate was covered by mucosal tissue, without cystic formations. Conclusion. The mucoperiosteal palatal flap can be easily, successfully and maximally safely applied in the resolution of VPI in patients with DiGeorge syndrome where there is an aberrant submucosal position of the ICA. This flap could be a ?flap of choice? for such patients with atopic position of the ISA, too.

Carotid artery mobilization prior to pharyngeal flap inset for patients with 22q11.2 deletion syndrome

The management of velopharyngeal insufficiency (VPI) in patients with 22q11.2 deletion syndrome (22q11DS) poses a significant clinical challenge due to presence of a large velopharyngeal gap and a relatively high rate of internal carotid artery (ICA) medialization. To our knowledge, we are the first group to have successfully managed VPI in a series of seven pediatric patients with 22q11DS with medialized ICAs via a novel surgical technique involving carotid artery mobilization followed by pharyngeal flap insertion. Thus far, we have found this technique to be reliably safe with no significant morbidity and caregivers have reported postoperative improvement in speech, swallowing and nasal regurgitation symptoms. Herein, we provide a detailed description of our novel surgical approach, including an instructional video, for correction of VPI in patients with medialized ICAs, who have previously had limited management options.

Clinical Findings and Outcomes of Palatal Repair in 9 Patients With Van der Woude Syndrome.

Van der Woude syndrome (VWS), an autosomal dominant condition associated with clefts of the lip and/or palate and lower lip pits, is caused by mutations in interferon regulatory factor 6 gene. It is reported to be the most common syndromic cleft worldwide. This case series presents the phenotypic characteristics and treatment outcomes in a group of 9 patients diagnosed with VWS. A retrospective review was performed on records of patients given a diagnosis of VWS presenting to the Department of Plastic Surgery of Sohag University between July 2009 and November 2019. Data analyses included age and sex of affected patients, type of the cleft, associated anomalies, presence of lower lip pits, and history of lower lip pits/cleft in the family and treatment outcomes. The study identified 9 patients (male = 2, female = 7). Age at first presentation ranged between 1 week and 7 years (mean = 1.3 years). Four patients had bilateral cleft lip and palate and 1 patient had unilateral cleft lip and palate (UCLP), whereas 4 patients had isolated cleft palate. Bilateral lower lip pits were presented in 8 patients, whereas the ninth patient has unilateral pit. Family history was positive in 3 patients. Most patients in this study developed after palatal repair speech problems with an increased rate of secondary surgical procedures needed for correction of velopharyngeal insufficiency. All reviewed cases of VWS presented with lower lip pits and cleft palate with or without cleft lip. A positive family history of similar conditions was demonstrated in 33.3% of our patients. This study suggests an increased incidence of secondary palatal surgeries for velopharyngeal insufficiency in patients with VWS; this warrant further studies including control group of nonsyndromic cleft patients.

Velopharyngeal Insufficiency in Craniofacial Microsomia: Prevalence, Diagnosis, and Treatment

BACKGROUND: Craniofacial microsomia (CFM) is characterized by malformations of facial structures that are derived from the first and second brachial arches. Although hearing, occlusion, and facial paralysis are the most typical functional considerations for CFM, abnormalities in speech, including velopharyngeal insufficiency (VPI), have also been sparingly reported in several studies. As a result, the purpose of this multicenter study was to analyze the prevalence and management of VPI in patients with CFM. Furthermore, this study sought to investigate the effects of concomitant cleft lip and/or palate (CL/P) on VPI in CFM patients. METHODS: A retrospective chart review of patients from the University of California, Los Angeles Craniofacial Clinic and the Orthopaedic Institute for Children in Los Angeles was conducted. Inclusion criteria included patients who were diagnosed with CFM, first and second brachial arch syndrome, oculo-auriculo-vertebral sequence, facio-auriculo-vertebral syndrome, or Goldenhar syndrome. Patients with isolated microtia were excluded from this study. Included CFM patients were stratified based on the presence or absence of CL/P, and all patients were evaluated for VPI, methods of diagnosis, speech therapy, and surgery. All patients received at least 1 thorough evaluation by a speech pathologist and were diagnosed clinically with VPI if they were noted to have any hypernasal speech, nasal air emission, or nasal turbulence. Chi-square tests and Levene’s test (P ≤ 0.05) were used for analysis. RESULTS: Overall, 78 patients with CFM (48 males, 61.5%) were assessed for VPI, aged 4–34 years old at time of review. In the entire cohort, 22 (28.2%) patients were found to be diagnosed with VPI. Of the 78 patients, 8 (10.3%) patients had concomitant CL/P. Of the 70 CFM patients without CL/P, 14 (20.0%) had VPI. Eight (57.1%) of these patients were recommended for nasoendoscopy, whereas none of these patients required any corrective VPI surgery. Comparatively, all 8 CFM with CL/P patients were diagnosed with VPI and recommended for nasoendoscopy, significantly higher rates than those without CL/P. Furthermore, 6 (75.0%) of these patients eventually underwent VPI surgery, significantly more than those without CL/P. CONCLUSIONS: This study establishes an overall rate of VPI in CFM at 28.2%, with the largest cohort of CFM looking into VPI in the literature. All of the CFM patients with CL/P had VPI, with a majority requiring surgery, compared with only a fifth of CFM patients without CL/P having VPI and none needing surgery. Findings from this study highlight VPI as a common problem in CFM patients who should be diagnosed and managed early on. In addition, this study displays CL/P as a risk and severity factor for VPI.

Predicting Velopharyngeal Insufficiency in Patients With Cleft Palate

Predicting Velopharyngeal Insufficiency in Patients With Cleft Palate

Velar Closing Ratio As a Predictor for the Verlopharyngeal Function After Double Opposing Z-Plasty for Postpalatoplasty Velopharyngeal Insufficiency in Patients With Cleft Palate.

This study was designed to identify the potential predictors of postoperative velopharyngeal function after double opposing Z-plasty (DOZP) for the treatment of velopharyngeal insufficiency (VPI) in patients who had prior palatoplasty for cleft palate. This retrospective study reviewed the medical records of consecutive patients who received DOZP for VPI after receiving a prior palatoplasty treating cleft palate between 2004 and 2017. The speech outcome of patient was measured using the Pittsburgh Weighted Speech Scale (PWSS) at 6 months following surgery and determined the outcome suggests velopharyngeal competence (PWSS ≤2) or incompetence (PWSS >2). Stepwise logistic regression was used to identify the variables for the prediction of competent surgical outcome. The specific receiver operating characteristic curves with an area under the curve (AUC) was used to evaluate the predictor related to the surgical outcome as competence. The study included 93 patients. Age, relative velar length, velar lengthening, and closure pattern were not significantly associated with postoperative competence status of the patient. The only variable that predicted a successful surgical outcome was preoperative velar closing ratio. However, the accuracy of velar closing ratio in predicting a competent surgical outcome is only moderate (AUC = 70.37). The results of this study showed that preoperative velar closing ratio may predict, with moderate accuracy, a successful surgical outcome in patients with postpalatoplasty VPI who undergo DOZP. Therefore, in patients with a low preoperative velar closing ratio, some alternative surgical methods other than DOZP may be considered to avoid unsatisfactory surgical outcome.

Speech Outcomes Comparison Between Adult Velopharyngeal Insufficiency and Patients With Unrepaired Cleft Palate.

This study compared the speech outcomes of adult velopharyngeal insufficiency patients and adult cleft palate (ACP) patients, and explored whether there was any difference in the phonological level of these 2 types of patients. Perceptual evaluation was used to assess speech intelligibility, hypernasality and compensatory articulation in 89 adult patients with velopharyngeal insufficiency and 35 adult patients with unrepaired cleft palate. Each group was divided into complete cleft palate and incomplete cleft palate (including submucous cleft palate). The phonological differences were compared between the 2 groups of patients and 2 types of cleft palate. The mean speech intelligibility was 43.04% in velopharyngeal insufficiency group and 32.87% in ACP group. There was a significant difference in speech intelligibility between the 2 groups by T test, t = 2.916 (P < 0.01), speech intelligibility between 2 types of cleft palate was no significant difference. Also, there was a significant difference between the 2 groups in the constitution of hypernasality degree by Chi-Square test, x2 = 31.650 (P < 0.01), compensatory articulation were present in 74.3% ACP patients (26/35) and 47.2% velopharyngeal insufficiency patients (42/89), x2 = 7.446 (P < 0.01), there was a significant difference in incidence of compensatory articulation between the 2 groups. Adult patients with unpaired cleft palate present an even worse speech intelligibility and hypernasality degree than velopharyngeal insufficiency patients after cleft palate repair, regardless of the cleft type. Additionally, patients in ACP group have a higher incidence of compensatory articulation than that in incomplete cleft palate group. In sequenced treatments of cleft lip and palate, evaluation and treatment of speech disorders cannot be ignored.

Pharyngeal bulb prosthesis and speech outcome in patients with cleft palate

IntroductionIndividuals 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. ObjectiveThis 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. MethodsThirty 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. ResultsSeventy 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). ConclusionThe use of the pharyngeal bulb prosthesis is an effective approach to eliminate hypernasality related to velopharyngeal insufficiency.
