Abstract
OBJECTIVE 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. PARTICIPANTS AND INTERVENTION 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). RESULTS 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. CONCLUSIONS 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.

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
Cleft palate is among the most common congenital disorders worldwide and is correctable through surgical intervention. Sub-optimal surgical results may cause velopharyngeal insufficiency (VPI). When symptomatic, VPI can cause hypernasal or unintelligible speech. The postoperative risk of VPI varies significantly in the literature but may be attributed to differences in study size, cleft type, surgical technique, and operative age. To identify the potential impact of these factors, a systematic review was conducted to examine the risk of VPI after primary palatoplasty, accounting for operative age and surgical technique. A search of PubMed, Embase, and Web of Science was completed for original studies that examined speech outcomes after primary palatoplasty. The search identified 4740 original articles and included 35 studies that reported mean age at palatoplasty and VPI-related outcomes. The studies included 10,795 patients with a weighted mean operative age of 15.7 months (range: 3.1-182.9 mo), and 20% (n=2186) had signs of postoperative VPI. Because of the heterogeneity in reporting of surgical technique across studies, small sample sizes, and a lack of statistical power, an analysis of the VPI risk per procedure type and timing was not possible. A lack of data and variable consensus limits our understanding of optimal timing and techniques to reduce VPI occurrence. This paper presents a call-to-action to generate: (1) high-quality research from thoughtfully designed studies; (2) greater global representation; and (3) global consensus informed by high-quality data, to make recommendations on optimal technique and timing for primary palatoplasty to reduce VPI.

Abstract
Primary cleft lip and palate surgeries can interfere with speech status, facial appearance, maxillary growth, and psychosocial and academic development. Therefore, different surgical protocols and techniques have been proposed, and adequate velopharyngeal function and speech is the main goal for the treatment success. The present study aimed to report preliminary speech results of the 2-stage palate repair of children with unilateral cleft lip and palate. One hundred seventy nonsyndromic patients with unilateral cleft lip and palate were included in this report, 35% males and 65% females, submitted to the 2-stage palatoplasty protocol, composed by lip, nasal ala, and hard palate repair at 3 to 6 m (stage 1) and soft palate repair at 12 to 18 m (stage 2). The target age range for speech recording was 5 to 10 years, and the speech material included repetition of Brazilian Portuguese sentences. These samples were obtained over 5 years and assessed by 3 of 14 experienced speech pathologists. When discordant, the majority rate was adopted. Average velopharyngeal dysfunction (VPD) rates were 19,5%, varying according to the soft palate technique, with better results when the Sommerlad technique was performed (VPD=11%), followed by Braithwaite (VPD=15%) and then Von Langenbeck (VPD=25%). Passive errors were observed in 32% and active errors in 25%. Speech results reflect the outcomes of an interdisciplinary team's work, where facial growth and nasolabial appearance must also be considered. Further analysis and a wider casuistic are recommended. Hence outcomes audit needs to be a permanent process, providing solid and updated evidence for optimal cleft care.

Abstract
BACKGROUND Although some cleft palates show asymmetric palatal shelf length and/or width intraoperatively, the relationship between palate asymmetry and speech outcomes has not been fully investigated. METHODS This study retrospectively reviewed 234 patients who underwent double-opposing Z-plasty (DOZ) for isolated cleft palate (Veau class I and II). Speech outcomes were analyzed to evaluate the association with width and length discrepancy of the palatal shelves using multiple logistic regression adjusting for patient age. RESULTS The mean age at repair was 14.2 ± 5.26 months. The mean palatal shelf width and length differences were 0.87 ± 0.97 mm and 1.63 ± 1.61 mm, respectively. The mean age at initial and follow-up assessment was 37.6 ± 5.70 months ( n = 234) and 66.2 ± 8.81 months ( n = 120), respectively. Multivariate logistic regression analysis of initial speech outcomes showed odds ratios in width discrepancy of 1.67 ( P = 0.0703), 1.59 ( P = 0.0104), and 2.01 ( P = 0.0051) for nasal emission, hypernasality, and compensatory articulation, respectively. Additional analysis including follow-up outcomes also revealed that width discrepancy of the palatal shelves had higher odds ratios for nasal emission, hypernasality, and compensatory articulation (OR, 1.49, P = 0.0406; OR, 1.36; P = 0.0660; and OR, 1.65; P = 0.0170, respectively). There was no association between length discrepancy and all speech abnormalities. CONCLUSIONS Greater discrepancies in palatal shelf width, rather than in length, were associated with poorer speech outcomes after DOZ. The authors suggest that DOZ is effective for longitudinally asymmetric cleft palates. CLIINCAL QUESTION/LEVEL OF EVIDENCE Risk, III.

Abstract
PURPOSE Following transoral robotic surgery (TORS) for oropharyngeal carcinoma (OPC), velopharyngeal incompetence (VPI) is a known consequence that may contribute to swallowing and speech disorders. As the incidence of OPC increases affecting a younger demographic, a better understanding of VPI is required to support speech and swallowing rehabilitation. METHOD A scoping review was conducted using Arskey & O'Malley's framework. Studies were identified from five databases between 2007 and 2020. The methodological quality was measured with the RevMan Risk of Bias Tool by two independent evaluators. RESULT A total of seven studies met the inclusion criterion. There was a combined total of 306 participants, their average age was 59.2 years. A high risk of bias and degree of heterogeneity across all seven cohort studies was observed. Validated and instrumental evaluations of VPI were present in two papers, with the majority only reporting the presence or absence of VPI. The incidence of VPI reported in each study ranged from 0 to 53%, (median 3.5%). CONCLUSION There are few high-quality studies and considerable heterogeneity in the terminology, inclusion criteria and measurement of VPI. Instrumentation, to date, has been rarely used but is necessary for a normed and validated approach to VPI. Based on this review, there is considerable need for larger studies which instrumentally and longitudinally assess VPI as a consequence of TORS, in order to guide patient education and management prior to, and following their surgery.

Abstract
BACKGROUND Velopharyngeal insufficiency is a commonly encountered problem in Cleft Surgery, with pharyngoplasty being the mainstay of surgical management. In this study we aim to investigate the indications and outcomes of a single institution's experience and compare to international literature. METHODS A retrospective review was performed looking at over 100 consecutive primary pharyngoplasty operations for velopharyngeal dysfunction over a 10-year period at a single institution. Aetiology, peri-operative course and speech outcomes for the cohort between January 2010 through January 2020 were assessed. A comprehensive literature review was performed for comparison and analysis of the studies' data. RESULTS Ninety-seven consecutive patients were included in the study on which 103 operations were performed. Average age at time of surgery was 7.25 years old. Approximately 37% of the patients had a diagnosed syndrome, sequence or chromosomal abnormality. Ninety-seven of the 103 operations were primary pharyngoplasties, 4 were revision pharyngoplasties and 2 return to theatre procedures. Regarding speech outcomes, 51% of the patients that had formal speech assessments were found to have a significant improvement, 42% moderate improvement and 7% had no improvement. 93% of the patients that underwent pharyngoplasty in this study had significant or moderate improvement in speech outcomes. These speech outcomes and post-operative complications such as obstructive sleep apnoea are analysed. CONCLUSION This study demonstrates that pharyngoplasty is a safe procedure for velopharyngeal insufficiency with a good overall success rate. The major outcomes assessed including complications & safety, revision rate and speech outcomes are comparative to previous international studies.

Abstract
BACKGROUND Numerous authors have reported their outcomes after using Furlow's palatoplasty for cleft palate repair. However, little attention has been given to the operative complications associated with this technique. The present study was carried out to present cases and analyze the various factors influencing the development of this complication accompanying Furlow's palatoplasty. MATERIALS AND METHODS This is a case report study of patients with cleft palate admitted to our center due to sequelae after primary cleft palate repair using Furlow palatoplasty between 2003 and 2021. Patient information was identified from the Smile Train cleft charity organization, parents' reports, and hospital records (intake forms and operating room registries). RESULTS Five patients were identified as having secondary cleft palate with palatal flap necrosis and associated with Furlow palatoplasty during patient evaluation at our center between 2003 and 2021. The observed prevalence was 1.54%. CONCLUSIONS Palatal flap necrosis is a rare but serious complication after primary Furlow's palatoplasty. The occurrence of this complication can be reduced by careful preoperative planning, and prevention is possible.

Abstract
BACKGROUND 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. METHODS 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. RESULTS 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). CONCLUSIONS Our study showed that overlapping IVVP could provide successful correction of velopharyngeal insufficiency in patients with SMCP, including relatively old patients.

Abstract
BACKGROUND & AIM To assess consonant proficiency and velopharyngeal function in 10-year-old children born with unilateral cleft lip and palate (UCLP) within the Scandcleft project. METHODS & PROCEDURES Three parallel group, randomized, clinical trials were undertaken as an international multicentre study by nine cleft teams in five countries. Three different surgical protocols for primary palate repair (Arm B-Lip and soft palate closure at 3-4 months, hard palate closure at 36 months, Arm C-Lip closure at 3-4 months, hard and soft palate closure at 12 months, and Arm D-Lip closure at 3-4 months combined with a single-layer closure of the hard palate using a vomer flap, soft palate closure at 12 months) were tested against a common procedure (Arm A-Lip and soft palate closure at 3-4 months followed by hard palate closure at 12 months) in the total cohort of 431 children born with a non-syndromic UCLP. Speech audio and video recordings of 399 children were available and perceptually analysed. Percentage of consonants correct (PCC) from a naming test, an overall rating of velopharyngeal competence (VPC) (VPC-Rate), and a composite measure (VPC-Sum) were reported. OUTCOMES & RESULTS The mean levels of consonant proficiency (PCC score) in the trial arms were 86-92% and between 58% and 83% of the children had VPC (VPC-Sum). Only 50-73% of the participants had a consonant proficiency level with their peers. Girls performed better throughout. Long delay of the hard palate repair (Arm B) indicated lower PCC and simultaneous hard and soft palate closure higher (Arm C). However, the proportion of participants with primary VPC (not including velopharyngeal surgeries) was highest in Arm B (68%) and lowest in Arm C (47%). CONCLUSIONS & IMPLICATIONS The speech outcome in terms of PCC and VPC was low across the trials. The different protocols had their pros and cons and there is no obvious evidence to recommend any of the protocols as superior. Aspects other than primary surgical method, such as time after velopharyngeal surgery, surgical experience, hearing level, language difficulties and speech therapy, need to be thoroughly reviewed for a better understanding of what has affected speech outcome at 10 years. WHAT THIS PAPER ADDS What is already known on the subject Speech outcomes at 10 years of age in children treated for UCLP are sparse and contradictory. Previous studies have examined speech outcomes and the relationship with surgical intervention in 5-year-olds. What this study adds to the existing knowledge Speech outcomes based on standardized assessment in a large group of 10-year-old children born with UCLP and surgically treated according to different protocols are presented. While speech therapy had been provided, a large proportion of the children across treatment protocols still needed further speech therapy. What are the potential or actual clinical implications of this work? Aspects other than surgery and speech function might add to the understanding of what affects speech outcome. Effective speech therapy should be available for children in addition to primary surgical repair of the cleft and secondary surgeries if needed.

Abstract
Velopharyngeal insufficiency is a disorder where the soft palate directs the air through the nose. It is often present in patients with previous cleft or short palate, but also in many other conditions. Symptoms are primarily to be found in speech, with very distinct nasal sound. After clinical evaluation and nasal endoscopy, surgery is considered. Several surgical techniques are in use, with posterior pharyngeal flap pharyngoplasty being most widely used. This method leaves the base of the posterior pharyngeal flap attached to the posterior pharyngeal wall, with two lateral ports on each side of the flap. Permanent nasopharyngeal obstruction is a very challenging pathology for anesthesiologists in case of mandatory nasal intubation since it is a relative contraindication for nasal intubation. Patients with previous palatoplasty will regularly appear in our routine anesthetic practice, in all surgical segments. The high risk of damage to the flap with possible bleeding can put the anesthesiologist in a very unpleasant situation if not aware of the permanent effect of this surgery. During preanesthetic assessment, if there is information on a previous pharyngoplasty, one should consider alternative options for nasotracheal intubation. All nasal insertion procedures must be either avoided or carried out with great caution, under fiberoptic visual control.

Abstract
BACKGROUND Velopharyngeal insufficiency involving a large velopharyngeal gap and poor lateral wall movement is referred to as a "black hole" and remains a challenging problem for cleft surgeons. The effect of the pharyngeal flap on this form of velopharyngeal insufficiency is still debatable because a wide pharyngeal flap is associated with a high incidence of airway obstruction. The present study aimed to evaluate the speech outcomes of combined overlapping intravelar veloplasty and dynamic sphincter pharyngoplasty for the treatment of velopharyngeal insufficiency. METHODS Between March 2016 and June 2019, 15 patients with velopharyngeal insufficiency were treated with a combination of overlapping intravelar veloplasty and dynamic sphincter pharyngoplasty. Preoperative speech evaluation was performed on the basis of perceptual speech evaluation, nasometry, and nasoendoscopy. Postoperative speech evaluation using the same approach as that used preoperatively was performed after completion of speech therapy. RESULTS All 15 patients achieved satisfactory velopharyngeal port closure and speech phonation after completion of speech therapy. No additional procedures were performed to improve velopharyngeal port closure and speech production. The preoperative and postoperative results of perceptual speech evaluation, nasometry, and nasoendoscopy evaluation were significantly different (P < 0.01). CONCLUSION Combined treatment with overlapping intravelar veloplasty and dynamic sphincter pharyngoplasty can correct the velopharyngeal insufficiency "black hole" with highly reliable results and minimal risk of airway obstruction.

Abstract
INTRODUCTION Velopharyngeal insufficiency (VPI), a stigmatizing hallmark of palatal dysfunction, occurs in a wide spectrum of pediatric craniofacial conditions. The mainstays for surgical correction include palate repair and/or pharyngeal surgery. However, primary pharyngoplasty has a failure rate of 15% to 20%. Although revision pharyngoplasty may be necessary in those with persistent VPI, little is known regarding the indications for and outcomes after such procedures. The purpose of this study is to describe the authors' experience with indications for and outcomes after revision pharyngoplasty. METHODS A single-center retrospective review was performed of all patients undergoing revision pharyngoplasty between 2002 and 2019. Demographic data and Pittsburgh Weighted Speech Scores, diagnoses, comorbidities, and complications were tabulated. Two-tailed Student t test was used, and a P value of 0.05 or less was considered statistically significant. RESULTS Thirty-two patients (65.6% male) met inclusion criteria for this study. The most common diagnoses included cleft palate (68.8%), submucous cleft palate (SMCP, 18.8%), and congenital VPI (6.3%, likely occult SMCP). Most patients (84.4%) underwent palatoplasty before their initial pharyngoplasty. The primary indication for initial pharyngoplasty was VPI (mean age 7.1 ± 4.6 years). The most common indication for revision pharyngoplasty (mean age 11.2 ± 5.1 years) included persistent VPI (n = 22), followed by obstructive sleep apnea (OSA) (n = 11). Persistent VPI (n = 8) and OSA (n = 6) were the most common complications after secondary pharyngoplasty. Thirteen patients (40.6%) within the revision pharyngoplasty cohort required additional surgical intervention: 4 underwent tertiary pharyngoplasty, 4 underwent takedown for OSA (n = 3) or persistent VPI (n = 1), 3 underwent takedown and conversion Furlow for persistent VPI (n = 2), OSA (n = 2) and/or flap dehiscence (n = 1), and 2 underwent palatal lengthening with buccal myomucosal flaps for persistent VPI. Of the 4 patients who required a tertiary pharyngoplasty, the mean age at repair was 6.6 ± 1.1 years and their speech scores improved from 13.5 to 2.3 after tertiary pharyngoplasty (P = 0.11). The overall speech score after completion of all procedures improved significantly from 19 to 3.3. CONCLUSION Patients who fail primary pharyngoplasty represent a challenging population. Of patients who underwent secondary pharyngoplasty, nearly half required a tertiary procedure to achieve acceptable speech scores or resolve complications.

Abstract
The dynamic of velopharyngeal sphincter mechanism is a complex motor skill involving coordination of soft palate and posterior and lateral pharyngeal walls. At rest, the soft palate drapes downward so that the oropharynx and the nasopharynx open allowing for normal breathing. However, during deglutition and certain speech, sounds such as plosives require complete or nearly complete velopharyngeal closure, whereas during utterance of vowels, the port needs to be open at varying degrees. Defects in velopharyngeal mechanism lead to hypernasality and decreased intelligibility of speech. The aim of this article is to understand the technique used to rehabilitate a patient with velopharyngeal insufficiency using a palatopharyngeal obturator prosthesis connected via a metal velar connector to a maxillary complete denture, with nasal endoscopic and lateral cephalometric examinations done to evaluate the outcome.

Abstract
BACKGROUND The purpose of this study was to evaluate the comparative incidence of obstructive sleep apnea following velopharyngeal insufficiency surgery in the United States. METHODS A retrospective analysis of cleft and noncleft pediatric patients who underwent velopharyngeal insufficiency surgery was performed using the IBM MarketScan Commercial Database. Patients were tracked longitudinally from 2007 to 2016 to evaluate the incidence of obstructive sleep apnea. Multivariable regression was used to evaluate predictors of postoperative obstructive sleep apnea and surgical revision. RESULTS A total of 1098 patients underwent a pharyngeal flap (61.0 percent), sphincter pharyngoplasty (22.2 percent), or palatal lengthening with or without island flaps (16.8 percent). Diagnoses were predominantly cleft lip and/or palate (52.8 percent) and congenital oropharyngeal anomalies (42.6 percent). Eighty patients (7.3 percent) developed obstructive sleep apnea at an average of 10.2 months postoperatively. Predictors of obstructive sleep apnea included older age (p = 0.014) and head and neck neoplasm (p = 0.011). The obstructive sleep apnea rate following sphincter pharyngoplasty was 11.1 percent, compared to 7.2 percent after pharyngeal flap surgery. Compared to sphincter pharyngoplasty, pharyngeal flap surgery was associated with a lower risk of further surgery (OR, 0.43; p = 0.010). Of patients with cleft lip and/or palate, 35 developed obstructive sleep apnea (6.0 percent) without a significant association with procedure type. CONCLUSIONS In this national claims database analysis of cleft and noncleft pediatric patients, the rate of obstructive sleep apnea following velopharyngeal insufficiency surgery was not significantly different for pharyngeal flap compared to sphincter pharyngoplasty. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, III.

A perceptual outcome measure of velopharyngeal function based on the Cleft Audit Protocol for Speech-Augmented (CAPS-A VPC-Sum): Validation through a speech osteotomy study. INTERNATIONAL JOURNAL OF LANGUAGE & COMMUNICATION DISORDERS 2021; 56:754-767. [PMID: 34022774 DOI: 10.1111/1460-6984.12625] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/08/2020] [Revised: 03/31/2021] [Accepted: 04/01/2021] [Indexed: 06/12/2023]
Abstract
BACKGROUND The status of the velopharyngeal mechanism can be inferred from perceptual ratings of specified speech parameters. Several studies have proposed the measure of an overall velopharyngeal composite score based on these perceptual ratings and have reported good validity. The Cleft Audit Protocol for Speech-Augmented (CAPS-A) is a validated and reliable perceptual framework for the assessment of cleft speech and velopharyngeal function used by all Regional Cleft Services in the UK and Ireland. An overall velopharyngeal composite summary score based on the CAPS-A would serve as an important surgical outcome measure of speech. AIMS To develop and validate a velopharyngeal composite summary score based on perceptual ratings made on the CAPS-A (CAPS-A VPC-Sum) using data from a maxillary osteotomy (MO) study. METHODS & PROCEDURES There were two surgical groups: a cleft lip and palate (CLP) (N = 20) group and a non-CLP group (N = 10), and a normal control group (N = 20). Participants in groups 1 and 2 were seen for perceptual and instrumental assessments of speech and velopharyngeal function preoperatively (T1), 3 months (T2) and 12 months (T3) postoperatively. Perceptual speech data were collected and rated by independent listeners using CAPS-A. OUTCOMES & RESULTS Moderate to strong interrater reliability for perceptual data (rs = 0.503-1.000, all p < 0.01) and strong to very strong reliability for videofluoroscopic measurements (rs = 0.746-0.947) were found. Construct validity of the CAPS-A VPC-Sum was shown by an increase in postoperative scores for the CLP group only ϰ2 (2) = 9.769, p = 0.008 and significant differences between the CLP and the other two groups at T2 and T3 using independent t-tests. Convergent and divergent validity was indicated by a positive moderate correlation with related parameters (e.g., hypernasality rs = 0.869, p < 0.01) and a weak correlation with unrelated parameters (e.g., amount of forward advancement rs = 0.160, p = 0.526). Criterion validity was found by a moderate correlation between closure ratio rs = -0.541, p = 0.020 and CAPS-A VPC-Sum. CONCLUSIONS & IMPLICATIONS A velopharyngeal composite score based on perceptually rated parameters serves as an important surgical speech outcome measure. The CAPS-A VPC-Sum is a useful, reliable and valid outcome measure of velopharyngeal function. There are added positive implications for other clinicians using geographically and language-specific adapted versions of the CAPS-A internationally. WHAT THIS PAPER ADDS What is already known on this subject Velopharyngeal composite scores based on perceptually rated speech parameters have been shown to have both clinical and research utility, serving as a useful surgical outcome measure. However, such a composite score must be specifically validated on the perceptual speech framework upon which it is based, as there are differences in measurement methods and terminology across cleft speech perceptual frameworks internationally. What this paper adds to existing knowledge The CAPS-A is a nationally used tool in the UK and Ireland for audit and research purposes with validated and adapted international versions. This paper reports on the validation of the derived velopharyngeal composite score measure based on the CAPS-A and an English-speaking sample, providing evidence of its validity through a speech osteotomy study. What are the potential or actual clinical implications of this work? This work provides CLP teams who use CAPS-A with a validated surgical speech outcome measure of velopharyngeal function. It has positive implications also for adapted versions of the CAPS-A internationally.

Abstract
BACKGROUND Repair of cleft palate after 6 years of age is controversial in regard to the surgical procedure and the speech outcome. Primary repair alone may not be considered sufficient to achieve intelligible speech. The authors consider addition of pharyngeal flap at the time of primary repair to be a significant factor in improving speech. METHODS Prospectively maintained data of all cleft palate patients operated from 2013 to 2017 (5 years) was analyzed to identify patients older than 6 years. Complete cleft palate, incomplete cleft palate, and cleft of the soft palate were further stratified according to different Randall types. They were divided into 2 main types: primary palate repair only and primary palate repair with pharyngeal flap. Speech was assessed preoperatively and 12 months postoperatively by Pittsburgh weighted speech scale. RESULTS A total of 139 patients were analyzed. There were 78 males and 61 females. Their ages ranged from 6 to 60 years (mean age, 12.5 years). The overall preoperative speech score in palate repair-only group was 12.15, whereas the postoperative score was 7.32. In patients who underwent primary pharyngeal flap along with palate repair, the preoperative speech score was 11.3, and the postoperative score was 3.76. CONCLUSIONS In select group of patients who report late for palate repair, addition of pharyngeal flap along with the primary palate repair improves the speech outcome in all Randall groups.

Abstract
BACKGROUND Midface retrusion is a common problem in patients with cleft lip and palate owing to the lack of adequate growth of the maxilla. Midface advancement surgery is a definite treatment for midface retrusion; however, the subsequent oropharyngeal airway changes might result in velopharyngeal insufficiency (VPI) in affected patients. Determining the predictors of VPI beforehand and modifying the surgical procedure would be beneficial. MATERIALS AND METHODS A retrospective review of 42 patients with cleft lip and palate who underwent orthognathic surgery from 2013 to 2014 was performed. A total of 25 patients met the inclusion criteria and had undergone complete pre- and postsurgery videofluoroscopy, nasopharyngoscopy (NPS), and speech assessment. We compared 2 groups of patients, those who showed NPS finding changes of more than 0.1 (8 patients) and those without changes (17 patients), by measuring the distances of the contact point to the tip of the velum, gap size at maximum closure (MC) and rest, contact area length, lateral wall closure rate, closure velocity, and 2 angles (from the velum to the hard palate and genu) at MC and rest. The amount of maxillary advancement was also recorded. RESULTS Among the 8 patients with NPS finding changes, 3 underwent Furlow palatoplasty for VPI. No significant difference was found in the amount of maxillary advancement between the groups (5.8 vs 5.7 mm). Significant differences were found in the preoperative gap size at MC and angle at the genu at MC (P = 0.035 and .012). These could be considered as the predictors before surgery. After surgery, a significant difference was found in the contact area, lateral wall closure rate, and gap size at MC (P = 0.005, 0.018, and 0.01). CONCLUSION Videofluoroscopy is a relatively applicable method of determining dynamic changes in the velum function. By performing videofluoroscopy before midface advancement surgery in patients with cleft lip and palate, we may predict the risk of VPI and consider alternative surgical strategies.

Abstract
OBJECTIVE Palatoplasty outcome measurements vary widely among institutions. A standardized outcome metric would help provide quality benchmarks. DESIGN Retrospective review of primary palatoplasty patients from 2007 to 2013. SETTING Tertiary care children's hospital. MAIN OUTCOME MEASURES We created a novel conceptual quality metric called "OOR" (Optimal Outcome Reporting). Optimal Outcome Reporting is designed to reflect the percentage of patients with cleft palate who experience the best outcomes: one operation, velar competence by age 5 years, and no unintended palatal fistula. RESULTS Optimal Outcome Reporting was 72.3% (68/94). Eight patients had "suboptimal" outcomes for having undergone more than one operation. Eighteen patients failed for velar incompetence. No additional patients fell out of the algorithm for fistula. A significantly higher proportion of nonsyndromic patients demonstrated an "optimal" result compared to syndromic patients (61/80, 76.3% vs 7/14, 50.0%; P = .04). Patients who required more than one procedure had significantly more clinic visits (32.6 vs 14.9; P < .01) and accrued higher costs compared to "optimal" patients (US$34 019.88 vs US$15 357.25; P < .01). CONCLUSIONS Optimal Outcome Reporting represents a novel quality metric that can provide meaningful information for patients with cleft palate. Optimal Outcome Reporting utilization can help cleft centers adopt changes that matter to patients and their families. By allowing for cross-institutional comparisons in a clear and objective manner, OOR can promote competition, innovation, and value in cleft palate care.

Abstract
PURPOSE Velopharyngeal failure occurs as a result of a nasopharyngeal gap following inadequate velopharyngeal closure for structural or functional cause. We aimed to compare the soft palate length in two-flap palatoplasty with intravelar veloplasty (IVV) and two-flap palatoplasty with IVV plus double-layer Z-plasty combination in patients with cleft palate. METHODS This clinical trial was conducted on infants aged 9 to 12 months with cleft palate in two groups. The method of two-flap palatoplasty with IVV technique and two-flap palatoplasty with IVV plus double-layer Z-plasty was compared in terms of soft palate length which was measured during operation and short-term complications. RESULTS This study was conducted on 62 infants including 30 patients in two-flap palatoplasty with IVV group and 32 patients in two-flap palatoplasty with IVV plus double-layer Z-plasty group. The soft palate length in two-flap palatoplasty and IVV with and without Z-plasty groups before surgery was 17.56 ± 2.05 and 17.68 ± 1.88 mm, respectively (P = 0.561). After surgery, the soft palate length was significantly higher in two-flap palatoplasty with IVV plus Z-plasty group (22.43 ± 2.73 mm vs. 20.56 ± 2.42 mm) (P = 0.032). CONCLUSION The two-flap palatoplasty with IVV plus Z-plasty technique is a suitable method for increasing the palatal length in infants with cleft palate. On the other hand, the addition of Z-plasty method could increase the length of the palate. Moreover, the complications are very low and further trials for development of this method on patients with cleft palate are recommended. TRIAL REGISTRATION NUMBER (TRN) IRCT2017032423559N11.

Abstract
Background Velopharyngeal structure augmentation methods are used as alternatives to pharyngeal flap operations. Recently, we investigated the sites of velopharyngeal structure augmentation in dogs and reported that the most effective injection location is the soft palate. However, there have been no reports regarding the optimal materials for implantation or injection. In this study, we aimed to investigate the injectable materials used in soft palate augmentation in dogs to ameliorate velopharyngeal insufficiency (VPI). Methods Endoscopic soft palate augmentation (ESPA) was performed in dogs using purified sodium hyaluronate, atelocollagen, or autogenic fat tissue. ESPA is an original technique developed by our group, and this is the first report of its performance. Moreover, we assessed the amount of nasal air leakage during inspiration at rest and during expiration under the rebreathing system at 1, 2, 3, 4, 5, and 6 months after injection of these materials. Results The amount of nasal air leakage during expiration under the rebreathing system was significantly decreased in all dogs injected with the ESPA materials, but neither apnea nor hypopnea was observed. Conclusions We investigated the optimal materials for use in ESPA, such as purified sodium hyaluronate, atelocollagen, or autogenic fat tissue. We found that all of them reduced nasal air leakage and only autogenic fat tissue showed significant histologic differences in dogs at 6 months. This technique may also be useful for the treatment of patients with VPI.

Abstract
This systematic review (SR) aimed to evaluate speech and velopharyngeal function (VPF) changes of patients with cleft palate (CLP) after maxillary advancement (MA) surgery. A two-phase PROSPERO-registered SR (CRD42019141370) was conducted following the PRISMA statements. Search strategies were developed for main databases (PubMed, Scopus, Web of Science, COCHRANE, LILACS, and EBSCOhost) and Grey literature information sources. The GRADE tool was used to evaluate the quality of evidence. From a total of 908 articles, 10 (205 men and 147 women; mean age ranging from 18.0 to 25.7 years) were selected for meta-analysis. Moderate to high risk of bias (Rob) was observed. The most common methods for outcomes evaluation were the Nasometer (speech) and nasoendoscopy (VPF). Speech changed from normal to hypernasal, and VPF worsening were reported in most studies. Comparing maxillary advancement interventions (osteogenic distraction versus Le Fort I), no statistically significant differences were found regarding benefit on speech and VPF. In summary, the effect of MA on speech and VPF remains controversial in CLP patients. The RoB, inconsistencies, and imprecisions severely affected the overall quality of evidence. Further adequately delineated clinical studies are necessary to investigate the potential effect of MA interventions on speech and VPF in CLP patients.

Abstract
OBJECTIVES To compare dynamic magnetic resonance imaging (MRI) with videofluoroscopy (VFS) regarding image quality and assessment of gap size between soft palate (SP) and posterior pharyngeal wall (PPW) in children and adolescents following surgical correction of velopharyngeal dysfunction (VPD). METHODS Twenty-one patients undergoing unenhanced 3-T MRI and contrast-enhanced VFS were included in this IRB-approved prospective study. The MRI scan protocol comprised refocused gradient-echo sequences in transverse and sagittal planes during speech, with TE 1.97 ms, TR 3.95 ms, flip angle 8°, matrix size 128 × 128, and 5-mm slice thickness. Radial k-space sampling and sliding window reconstruction were used to achieve an image acquisition rate of 28 frames per second (fps). VFS with 30 fps was similarly performed in both planes. Closure of the velopharyngeal port during phonation was evaluated by two experienced radiologists. RESULTS Eleven (52.4%) patients displayed a complete closure, whereas ten (47.6%) patients showed a post-operative gap during speech. VFS and MRI equally identified the cases with persistent or recurrent VPD. Differences in SP-PPW distance between VFS (3.9 ± 1.6 mm) and MRI (4.1 ± 1.5 mm) were not statistically significant (p = 0.5). The subjective overall image quality of MRI was rated inferior (p < 0.001) compared with VFS, with almost perfect inter-rater agreement (κ = 0.90). The presence of susceptibility artifacts did not limit anatomical measurements. CONCLUSION Dynamic MRI is equally reliable as VFS to assess persistent or recurrent inadequate velum closure in patients following surgical treatment of VPD. KEY POINTS • Unenhanced 3-T dynamic MRI and contrast-enhanced videofluoroscopy are equally useful for the identification of patients with incomplete velopharyngeal closure during speech. • MRI using refocused gradient-echo acquisition with radial k-space sampling and sliding window reconstruction generates diagnostic images with 28 frames per second. • MRI can offer a radiation-free alternative to currently established videofluoroscopy for young patients.

Abstract
Purpose The purpose of this study is to examine the differences in velopharyngeal dimensions as well as levator veli palatini (levator) muscle morphology, positioning, and symmetry of children with repaired cleft palate with velopharyngeal insufficiency (VPI), children with repaired cleft palate with complete velopharyngeal closure, and children with noncleft anatomy. Method Fifteen children ranging in age from 4 to 8 years were recruited for this study. Ten of the participants had a history of repaired cleft palate, half with documented VPI and the other half with velopharyngeal closure. Five participants with noncleft anatomy were matched for age from a normative database. The magnetic resonance imaging protocol, processing methods, and analysis are consistent with that used in previous literature. Results Regarding velopharyngeal dimensions, median values were statistically significantly different between groups for sagittal angle (p = .031) and effective velopharyngeal ratio (p = .013). With respect to the levator muscle, median values were statistically significant for average extravelar length (p = .018), thickness at midline (p = .021), and thickness between the left and right muscle bundles at the point of insertion into the velum (p = .037). Remaining measures were not statistically significant. Conclusions The levator muscle is significantly different among these three groups with respect to thickness at midline, extravelar length, and symmetry at the point of insertion into the velum. Sagittal angle and effective velopharyngeal ratio are also significantly different. Participants with repaired cleft palate and VPI displayed the greatest degree of asymmetry. Future research should control for surgical procedure type to determine the impact of surgery on the levator muscle and surrounding velopharyngeal anatomy.
