Surgery For Velopharyngeal Insufficiency Research Articles

Primary Palatal Surgery in Nonsyndromic Cleft Palate Children and Velopharyngeal Insufficiency Correction Outcomes.

Speech has a very significant impact on the life quality of people with cleft and lip palate. Restore tissue anatomy and functionality is the main aim of primary palatal surgery. Multiple factors are associated with successful handling, including the need for a velopharyngeal insufficiency (VPI) secondary surgery. The study's aim is to determine speech and velopharyngeal function outcomes in children with cleft palate operated in our institution and to determine VPI secondary surgery outcomes, if appropriate. Clinical records of nonsyndromic patients with cleft palate born between January 2009 and December 2012, who performed their multidisciplinary care on our institution, were analyzed retrospectively. One hundred forty-two patients received primary palatal surgery. Eighty (56%) were male and 62 (44%) female. Twenty-two had soft cleft palate, 9 hard and soft cleft palate, 84 unilateral, and 27 bilateral cleft lip and palate. Twelve percent of patients presented palatal fistula, with a significantly higher presentation in Soft Cleft Palate and Hard and Soft Cleft Palate. Twenty-seven patients (19%) had surgical indication for VPI correction, and 20 of them received VPI surgery, before school age. Cleft type and gender were significantly associated with VPI surgery indication rate. Postsurgery, 80% presented normal resonance. Nasal emission improved in 85% of patients. Nasometry decreased from 45% to 31%. Hyponasality increased by 10%. One case presented total flap dehiscence. Preoperative planning must be done carefully and individualized to succeed. Future prospective research that considers all the variables for a correct analysis is advisable, to improve our results.

Speech and Audiology Outcomes After Single-Stage Versus Early 2-Stage Cleft Palate Repair.

The timing and management of patients with cleft palates have been controversial. Early soft palate closure at the time of cleft lip repair followed by hard palate closure at a second stage has been hypothesized to improve speech and audiology outcomes. This study compares cleft palate patients who have undergone single-stage versus 2-stage cleft palate repairs and the outcomes on speech and hearing. A retrospective chart review identified patients with diagnosis of cleft lip with complete cleft palate who underwent either single or 2-stage repair from 2006 to 2012. Data collected included age at each surgery, necessity of further speech surgery for velopharyngeal insufficiency, frequency of tympanostomy tube placement, presence of hearing loss, and speech assessment data graded per the validated Americleft speech scale. A total of 84 patients were identified and subdivided into groups of single-stage and 2-stage repair. The mean age at the time of single-stage palate repair was 13.3 months. For the 2-stage group, the mean ages were 4.2 and 11.8 months for the soft palate and hard palate repairs, respectively. Comparing the single-stage versus 2-stage palate repairs, there was no significant difference in all speech parameters including hypernasality, hyponasality, nasal air emission, articulation, expressive language, receptive language, speech intelligibility, and speech acceptability for both unilateral and bilateral cleft lip/palate patients. Two-stage repair was associated with increased number of tympanostomy tube placement compared with single-stage repair (relative risk, 1.74; P = 0.009), and the first set of tubes was performed at a statistically significantly younger age, 4.5 months in the 2-stage repair compared with 16.9 months in the single-stage (P = 0.012) with 87.5% performed with first stage of repair. However, there was no difference in the types, degrees of hearing loss, or the presence of at least mild conductive hearing loss at latest follow-up audiograms between the groups. There was no significant benefit with respect to speech or hearing outcomes between single-stage and 2-stage cleft palate repairs. This advocates for surgeon and family preference in the timing of cleft palate repair.

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.

NYU Nasoalveolar Molding Protocol: From Birth to Adulthood

INTRODUCTION: One of the most actively debated therapies for patients with a cleft is nasoalveolar molding (NAM). Although supporters cite improvements in nasal symmetry, nasal aesthetics, columellar length, cost benefit, and nasal revision rates, one of the most convincing criticisms of NAM is the absence of reports on its effects at facial maturity, the target timepoint of assessment for cleft care interventions. This study reports clinical outcomes of NAM to facial maturity including rates of revision surgery to the lip and nose, incidence of secondary alveolar bone graft (ABG), and orthognathic surgery (OGS), and effects on facial growth. METHODS: A single-institution retrospective review of patients all with a cleft who underwent NAM protocol from 1990 to 2000. Patients were included in the study if they had a diagnosis of unilateral or bilateral cleft lip and alveolus, with or without cleft palate. Patients were excluded if they had a syndromic diagnosis or if medical and/or dental records were incomplete. Lateral cephalogram measurements of patients with unilateral cleft lip and palate was obtained at 17 years or older and before OGS, if patients received OGS. These measurements were then compared with published Eurocleft cephalometric data. RESULTS: One hundred eighty-nine patients were identified, of which 100 met inclusion criteria. Eighteen patients had cleft lip and alveolus only. The average age at last follow-up visit was 20 years (15–26 years). Average age at time of unilateral cleft lip repair was 4 months (3–7 months), bilateral cleft lip repair 6 months (3–10 months), unilateral palate repair 13 months (4–27 months), and bilateral palate repair 13 months (6–17 months). Gingivoperiosteoplasty (GPP) was performed in 86% (86/100) of patients. ABG was performed in 52% (52/100). Of those who underwent GPP, ABG was avoided in 56% (48/86). A total of 23% (19/82) of patients with both cleft lip and palate required secondary surgery for velopharyngeal insufficiency (VPI), and 8% (4/48) of patients who underwent LeFort I advancement also required surgery for VPI. OGS was performed in 49% (49/100), and revisions to lip and/or nose prior to facial maturity were performed in 49% (49/100). At the time of lip and/or nose revision, 74% (36/49) were older than 14 years. Overall, 17% (17/100) required neither ABG, OGS, nor nose or lip revision. Thirty-four patients with unilateral cleft lip had lateral cephalograms available for analysis. There were no significant differences in SNA (P = 0.44), s-n-pg (P = 0.78), NSL/NL (P = 0.76), NSL/ML (P = 0.61), or n-sp/n-gn × 100 (P = 0.79) when compared with data from Eurocleft centers that used presurgical orthopedics. DISCUSSION: Cleft lip and palate reconstruction were not delayed because of NAM. Surgery for VPI and OGS rates were comparable to those reported in the literature. Facial growth analysis at facial maturity revealed no significant difference when compared with Eurocleft centers other than ANB (P = 0.005). These data suggest that NAM does not inhibit midface growth. Furthermore, ABG was avoided in 56% of patients who underwent GPP; lip and nose revision was avoided in 51%; and ABG, OGS, and any soft tissue revision surgery was avoided in 17%.

Management of Velopharyngeal Insufficiency in Cleft Patients With and Without Multidisciplinary Team Care.

To evaluate the effect of an American Cleft Palate-Craniofacial Association (ACPA)-approved multidisciplinary team on velopharyngeal insufficiency (VPI) diagnosis and treatment. Retrospective cohort setting; tertiary children's hospital patients; children with cleft palate repair identified through procedure codes. Velopharyngeal insufficiency diagnosis was assigned based on surgeon or team assessment. Age at diagnosis and surgery was recorded. Difference in age and rate of VPI diagnosis and surgery was analyzed with t test. Multivariate linear and logistic regression adjusted for confounding variables. Nine hundred forty patients were included with 71.5% cared for by an ACPA-approved multidisciplinary team. More (38.8% ) team care patients were found to have a diagnosis of VPI in comparison to 10% in independent care (P < .001). Team care was associated with an almost 6-fold increase in VPI diagnosis (P < .001). Team care was associated with a higher proportion of speech surgery (21% vs 10%, P < .001). Among children receiving team care, each visit was associated with 25% increased odds of being diagnosed with VPI (P < .001) and 20% increased odds of receiving speech surgery (P < .001). Age at VPI diagnosis and speech surgery were similar between groups (P = .55 and .29). Team care was associated with more accurate detection of VPI, resulting in more VPI speech therapy visits and surgical management. A higher number of team visits were similarly associated. Further studies of the clinical implication of timely and accurate VPI diagnosis, including quality of life assessments, are recommended to provide stronger guidance on team visit and evaluation planning.

Prioritizing Cleft/Craniofacial Surgical Care after the COVID-19 Pandemic.

It is anticipated that in due course the burden of emergency care due to COVID-19 infected patients will reduce sufficiently to permit elective surgical procedures to recommence. Prioritizing cleft/craniofacial surgery in the already overloaded medical system will then become an issue. The European Cleft Palate Craniofacial Association, together with the European Cleft and Craniofacial Initiative for Equality in Care, performed a brief survey to capture a current snapshot during a rapidly evolving pandemic. A questionnaire was sent to the 2242 participants who attended 1 of 3 recent international cleft/craniofacial meetings. The respondents indicated that children with Robin sequence who were not responding to nonsurgical options should be treated as emergency cases. Over 70% of the respondents indicated that palate repair should be performed before the age of 15 months, an additional 22% stating the same be performed by 18 months. Placement of middle ear tubes, primary cleft lip surgery, alveolar bone grafting, and velopharyngeal insufficiency surgery also need prioritization. Children with craniofacial conditions such as craniosynostosis and increased intracranial pressure need immediate care, whilst children with craniosynostosis and associated obstructive sleep apnea syndrome or proptosis need surgical care within 3 months of the typical timing. Craniosynostosis without signs of increased intracranial pressure needs correction before the age of 18 months. This survey indicates several areas of cleft and craniofacial conditions that need prioritization, but also certain areas where intervention is less urgent. We acknowledge that there will be differences in the post COVID-19 response according to circumstances and policies in individual countries.

The Effectiveness of the Buccal Myomucosal Flap on Speech and Surgical Outcomes in Cleft Palate: A Systematic Review

Purpose: A systematic review was conducted to assess speech and velopharyngeal competence outcomes following the buccal myomucosal flap surgical approach used for primary palatoplasty and secondary surgery for velopharyngeal insufficiency (VPI) in individuals with cleft palate. Methods: A systematic review was guided by the PRISMA guidelines. Articles were included if the patients received the surgical technique for primary cleft palate repair or secondary surgery for VPI and if the study provided detailed methods on the perceptual speech assessment or visualization of postoperative velopharyngeal anatomy. Results: A total of 1013 patients were included from 11 studies. Post-surgery, normal resonance was achieved in 77.4% of patients and no nasal air emission was reported in 54.7% of patients. An improvement in velopharyngeal closure was reported in 81.8% of patients. A variety of perceptual speech assessment scales and methods for assessing velopharyngeal competence were used in the studies. Conclusions: The review suggests that the buccal myomucosal flap procedure results in improved velopharyngeal closure as evidenced by physiologic observation and reported perceptual changes in speech intelligibility, resonance balance, and reduced nasal air emission. The development of an international, standardized method for assessing and reporting speech outcomes and velopharyngeal competency is recommended to ensure accurate comparisons between surgical techniques.

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

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. 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. 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). 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.

Non-Interventional Factors Influencing Velopharyngeal Function For Speech In Initial Cleft Palate Repair: A Systematic Review Protocol

BackgroundThis systematic review aims to inform the development of a screening tool which pre-operatively predicts which children are likely to develop velopharyngeal insufficiency, one of the causes of poor speech outcomes, following cleft palate repair. This would be highly beneficial as it would inform pre-operative counselling of parents, allow targeted speech and language therapy, and enable meaningful comparison of outcomes between surgeons, techniques, and institutions. Currently, it is unclear which factors influence speech outcomes. A systematic review investigating the non-interventional factors which potentially influence speech outcomes following cleft palate repair is warranted. This may be illuminating in itself or provide foundations for future studies.MethodsA systematic review will be carried out according to Cochrane methodology and reported according to PRISMA guidelines (PLoS Med 6: e1000097, 2009). Systematic review software will be used to facilitate three-stage screening by two independent reviewers experienced in cleft lip and palate. Thereafter, data extraction and GRADE assessment will be performed in duplicate by five independent reviewers experienced in cleft lip and palate. Studies reporting the proportion of patients who were recommended or underwent secondary speech surgery for velopharyngeal insufficiency following primary surgery for cleft palate will be included.The study findings will be tabulated and summarised. The primary outcome measure will be further speech surgery (either recommended or performed). The secondary outcome measure will be perceptual speech assessment for the presence of velopharyngeal insufficiency. A meta-analysis is planned. However, if this is not possible, due to the anticipated marked heterogeneity of study characteristics, pre-operative assessment, and the recorded outcome measures, a narrative synthesis will be undertaken.DiscussionThis systematic review may provide sufficient data to inform the development of a screening tool to predict the risk of velopharyngeal insufficiency prior to cleft palate repair. However, it is anticipated that these findings will provide the foundation for future studies in this area.Systematic review registrationRegistered on 19 December 2016 with PROSPERO CRD42017051624

Lateral pharyngeal flap with a double pedicle for repair of unilateral velopharyngeal insufficiency

ObjectivesConventional pharyngeal flap surgery, which closes the median portion of the velopharynx, has been performed for dysarthria patients with velopharyngeal insufficiency (VPI). However, for VPI due to unilateral pharyngeal paralysis, median closing disrupts pharyngeal contraction of the unaffected side and allows pharyngeal pressure to escape through the nose at the lateral portion of the affected side during speech and swallowing. The purpose of this study was to evaluate the effectiveness of lateral pharyngeal flap (LPF) surgery for unilateral VPI. MethodsSeven patients with unilateral VPI (five males and two females with an average age of 54 years) underwent LPF surgery combined with other transoral surgeries for dysphagia. The LPF surgical technique was as follows: after the laterocaudal-based pedicle flap of the soft palate and cranial-based pedicle flap of the posterior pharyngeal wall on the affected side were transorally elevated, each mucosal pedicle flap was sutured together. Functional oral intake scale (FOIS) scores and swallowing pressure before and after surgery were compared. ResultsUnilateral velopharyngeal closure preserved nasal breathing after LPF surgery in all patients. Rhinolalia aperta improved postoperatively in all patients except one. The mean FOIS scores were 2.3 preoperatively and 3.7, 5.3, and 5.9 at 2 weeks, 1 month, and 6 months postoperatively, respectively. The mean pressures significantly increased at the velopharynx (from 49±30mmHg to 92±45mmHg) and oropharynx (from 48±18mmHg to 66±15mmHg) six months after the surgery. ConclusionLPF surgery leaving the unaffected side intact can be an effective surgical procedure for patients with unilateral VPI.

Quality of life outcomes following velopharyngeal insufficiency surgery

ObjectivesVelopharyngeal 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. MethodsThis 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. ResultsTwenty-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. ConclusionChildren 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.

Management of velopharyngeal insufficiency by modified Furlow palatoplasty with pharyngeal flap: a retrospective outcome review

The surgical approach for the correction of residual velopharyngeal insufficiency requiring secondary surgery at Chang Gung Memorial Hospital is the modified Furlow palatoplasty with pharyngeal flap (mFP-PF). The aim of this study was to describe the mFP-PF technique and to determine the results obtained with regard to improvements in velopharyngeal function in patients undergoing this surgery. This retrospective analysis included 58 non-syndromic patients treated during the period 1992–2015 who complained of hypernasal speech after primary cleft palate repair and failed postoperative speech therapy. All of them underwent mFP-PF surgery. Preoperative and postoperative perceptual speech assessment results were obtained. The male to female ratio in the study group was 1.2:1, and the mean patient age at the time of surgery was 8.27 years. The patients underwent nasoendoscopic examination and the velar closing ratio was categorized as 0.1–0.4 in 53.4% and 0.5–0.7 in 46.6%. The assessment of speech after mFP-PF showed statistically significant changes for all perceptual speech outcomes. The incidence of repeat surgery was 3.4%. This study revealed that 96.6% of patients did not require second surgery for velopharyngeal insufficiency. Further studies on obstructive sleep apnoea in post-mFP-PF patients and improvements to the surgical technique should be considered.

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.

Palatal Protective Stents Prevent Oro-Nasal Fistulas after Surgery for Velopharyngeal Insufficiency: A Preliminary Report.

Background: One of the potential complications of surgery for velopharyngeal insufficiency (VPI) is postoperative oral-nasal fistula (ONF). Reported rates vary from 0 to 60%. Several factors are on account of these disproportionate rates. Objective: The purpose of this study was to describe the use of a palatal protective stent (PPS) to preserve the VPI repair surgical site and to study its effectiveness for decreasing the incidence of postoperative ONF. Materials and Methods: A retrospective study was carried out. All patients undergoing surgery for VPI with complete preoperative and postoperative evaluations including at least one year follow up after surgery from 2012 to 2016 were studied. Some of the patients were operated on using a pre-molded palatal protective stent (PPS). Twenty-seven patients were included in the study group. Most of the patients underwent a customized pharyngeal flap according to findings of imaging procedures. The remaining cases underwent a Furlow palatoplasty. Twelve patients were operated on using PPS. Results: There were no surgical complications during the procedures. ONF was detected in four of the patients operated on without PPS. None of the patients undergoing surgery using PPS demonstrated ONF. All fistulas were located at the soft/hard palate junction. VPI was corrected in 92% of the cases. Conclusion: Although only a reduced number of cases were studied, these preliminary results suggest that using PPS during surgical procedures for correcting VPI is a safe and reliable tool for preventing ONF.

Incidence of Speech-Correcting Surgery in Children With Isolated Cleft Palate.

Speech-correcting surgeries (pharyngoplasty) are performed to correct velopharyngeal insufficiency (VPI). This study aimed to analyze the need for speech-correcting surgery in children with isolated cleft palate (ICP) and to determine differences among cleft extent, gender, and primary technique used. In addition, we assessed the timing and number of secondary procedures performed and the incidence of operated fistulas. Retrospective medical chart review study from hospital archives and electronic records. These comprised the 423 consecutive nonsyndromic children (157 males and 266 females) with ICP treated at the Cleft Palate and Craniofacial Center of Helsinki University Hospital during 1990 to 2016. The total incidence of VPI surgery was 33.3% and the fistula repair rate, 7.8%. Children with cleft of both the hard and soft palate (n = 300) had a VPI secondary surgery rate of 37.3% (fistula repair rate 10.7%), whereas children with only cleft of the soft palate (n = 123) had a corresponding rate of 23.6% (fistula repair rate 0.8%). Gender and primary palatoplasty technique were not considered significant factors in need for VPI surgery. The majority of VPI surgeries were performed before school age. One fifth of patients receiving speech-correcting surgery had more than one subsequent procedure. The need for speech-correcting surgery and fistula repair was related to the severity of the cleft. Although the majority of the corrective surgeries were done before the age of 7 years, a considerable number were performed at a later stage, necessitating long-term observation.

Adults with 22q11.2 deletion syndrome have a different velopharyngeal anatomy with predisposition to velopharyngeal insufficiency

To find out if subjects with 22q11.2 deletion syndrome (DS) have a different velopharyngeal anatomy which could cause velopharyngeal insufficiency (VPI). A prospective study of 16 subjects >16 years of age with 22q11.2 DS, without overt cleft palate and without previous VPI surgery, and 48 healthy controls >18 years of age were included in the study. Speech was recorded and scored blindly by two independent senior speech therapists. All 64 individuals had MRI scans, which were analyzed blindly by a consultant radiologist. Subjects with 22q11.2 DS had a mild degree of weak pressure consonants (mean score); borderline to mild degree of hypernasality and audible nasal emission (mean score). All controls had normal speech. When comparing subjects (22q11.2 DS) to controls, we found the subjects to have the following: A shorter distance between left and right points of origin of the levator veli palatini muscle (LVP) (p < 0.0001); a more obtuse angle of origin of the LVP (bilaterally) (p < 0.009); a thinner LVP bilaterally and in the midline (p < 0.0001); a shorter LVP bilaterally (p < 0.0001); a shorter velum (p = 0.007); a larger osseous pharyngeal depth:velar length ratio (p = 0.01); a more obtuse anterior cranial base angle (nasion to sella to basion) (p < 0.0001) and posterior cranial base angle (sella to basion to foramen magnum) (p < 0.0001); a wider velopharyngeal width (p = 0.002) and a larger pharyngeal airway volume (p = 0.0007). Compared with healthy controls, adults with 22q11.2 DS showed a different velopharyngeal anatomy, which will make these individuals more prone to VPI.

Incidence of Secondary Surgery after Modified Furlow Palatoplasty: A 20-Year Single-Surgeon Case Series.

Objective To determine the occurrence of velopharyngeal insufficiency (VPI) requiring surgery and fistula repair after primary palatoplasty using a "modified" Furlow technique. Study Design Case series with chart review. Setting Academic multidisciplinary cleft and craniofacial center. Subjects and Methods Children younger than 18 years at presentation, with unrepaired cleft palate, with or without cleft lip, including submucous clefts, who underwent palatoplasty were included. No cleft patients having primary repair were excluded. All operations were conducted by a single surgeon from March 1994 through December 2013. Charts were reviewed for demographics, cleft type, genetic syndrome, operations performed, and complications, including VPI and oronasal fistula. Results In total, 312 consecutive patients underwent primary palatoplasty (160 [51.3%] male) with a median age of repair of 0.95 (range, 0.47-17.6) years and followed for 6.49 (range, 4.0-20.2) years. Robin sequence was diagnosed in 109 (34.9%), 104 (33.4%) had alveolar clefts, and 27 (8.7%) had concomitant gingivoperiosteoplasty. A modified Furlow was performed in 289 (92.6%). Overall, 16 (5.1%) required subsequent pharyngeal flap for VPI, and 48 (15.4%) required oronasal fistula repair. Veau class II had higher pharyngeal flap rates ( P = .033). Fistula repair was lower in Veau I ( P < .001) but higher in Veau II ( P < .001) and IV ( P = .002). Older age ( P = .034) and Robin sequence ( P = .017) were associated with higher rates of oronasal fistula repair. Conclusions The modified Furlow palatoplasty yields acceptable rates of secondary surgery for VPI without selection based on cleft width. While our oronasal fistula repair rate is high, it is concordant with previous reports and is likely related to our rare use of lateral relaxing incisions.

Centre-level variation in speech outcome and interventions, and factors associated with poor speech outcomes in 5-year-old children with non-syndromic unilateral cleft lip andpalate: The Cleft Care UK study. Part 4.

To investigate centre-level variation in speech intervention and outcome and factors associated with a speech disorder in children in Cleft Care UK (CCUK). Two hundred and sixty-eight 5-year-old British children with non-syndromic unilateral cleft lip and palate recruited to CCUK. Centre-based therapists undertook audio-video recordings. Perceptual analysis was undertaken using the CAPS-A tool. Speech outcomes were based on structural and articulation scores, and intelligibility/distinctiveness. Between-centre variation in treatment and outcomes were examined using multilevel models. These models were extended to estimate the association between a range of factors (hearing loss, speech intervention, fistula, secondary speech surgery for velopharyngeal insufficiency, socio-economic status, gender, and parental happiness with speech) and speech outcomes. There was centre-level variation in secondary speech surgery, speech intervention, structure and intelligibility outcomes. Children with a history of speech intervention had a lower odds of poor intelligibility/distinctiveness, 0.1 (95% CI: 0.0-0.4). Parental concern was associated with a higher odds of poor intelligibility/distinctiveness, 13.2 (95% CI: 4.9-35.1). Poor speech outcomes were associated with a fistula, secondary speech surgery and history of hearing loss. Within the centralized service there is centre-level variation in secondary speech surgery, intervention and speech outcomes. These findings support the importance of early management of fistulae, effective management of velopharyngeal insufficiency and hearing impairment, and most importantly speech intervention in the preschool years. Parental concern about speech is a good indicator of speech status.

Do Pharyngeal Flaps Restrict Early Midface Growth in Patients With Clefts?

To compare facial growth characteristics in patients with cleft palate who have undergone pharyngeal flap with those who had palatal lengthening or pharyngoplasty and to control subjects who have not had surgery for velopharyngeal insufficiency (VPI). Matched retrospective cohort study. Multidisciplinary cleft care center. All patients with cleft palate who had undergone pharyngeal flap or pharyngoplasty/palatal lengthening for VPI were included. Patients with craniofacial syndromes or those who had undergone maxillary protraction were excluded. A control group did not undergo surgery for VPI. The three groups were matched based on cleft type and ages at VPI surgery and cephalogram. Thirteen craniofacial measurements were evaluated on postoperative cephalograms using an analysis of variance with a Bonferroni adjustment for significant measures (α = 0.05). Seventy-two patients were included; mean ages at VPI surgery and postoperative cephalogram were 5 and 8 years, respectively. Twelve of thirteen craniofacial measures were not significantly different; notably, this included maxillary height and projection. Only gonial angle was found to differ significantly (P = .018) in that pharyngoplasty and pharyngeal flap yielded a smaller angle compared with that in control subjects. Facial growth, and in particular maxillary growth, was not altered as expected after pharyngeal flap surgery. Pharyngeal flap appears to be equivalent to pharyngoplasty and palatal lengthening in that no significant effects on early facial growth were detected after surgery for VPI in this cohort of children with cleft palate.

Using low level laser therapy to reduce early postoperative airway obstruction following modified Hogan's flap

Introduction and objectiveThe most common postoperative complications of velopharyngeal insufficiency surgery are postoperative bleeding and airway obstruction or obstructive sleep apnoea. Consequently, the aim of this study was to evaluate the effect of low level laser therapy (LLLT) during the first postoperative days in children undergoing superiorly based pharyngeal flap (SBF) surgery. Materials and methodsA randomized double blind clinical study on 30 children divided on two groups 15 patients each, who underwent SBF. LLLT was used in a group and the other was a control group. The study was conducted in academic tertiary care medical centres between 2013 and 2015. The degree of edema, oxygen saturation, occurrence of obstructive sleep apnoea (OSA) and steroid administration were recorded. ResultsThe mean of the average oxygen saturation was significantly less in the control group in the 1st and 2nd day as compared to the laser group. The need for oxygen and the incidence of OSA in the first 3 days were significantly higher in the control group as compared to the laser group. The degree of edema showed no significant difference in the first day but was significantly higher in the control group in the 2nd and 3rd days. Hence, the need of steroids was significantly higher in the control group in the first 3 days. ConclusionsPreliminary results showed that low level laser therapy is effective in reducing the incidence of early postoperative airway obstruction after SBF operations.
