Incidence of Velopharyngeal Insufficiency after Primary Cleft Palate Repair: A 27-Year Assessment of One Surgeon's Experience. Arch Plast Surg 2024; 51:284-289. [PMID: 38737842 PMCID: PMC11081726 DOI: 10.1055/a-2263-7857] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2023] [Accepted: 01/30/2024] [Indexed: 05/14/2024] Open
Abstract
Background Velopharyngeal insufficiency (VPI) is a major complication of cleft palate repair. The purpose of this study was to evaluate the incidence and predictive factors of VPI after cleft palate repair based on 27 years of one surgeon's experience. Methods Medical records were retrospectively reviewed for 652 patients who underwent cleft palate repair between 1995 and 2021. After exclusion of those with other syndromes or developmental disorders, the study included 374 patients with sufficient follow-up until the age of 4 years, when language evaluation was possible. VPI status was categorized through subjective and objective tests into normal, VPI, and borderline. We analyzed potential differences in VPI incidence by multiple factors. Factors with significance were analyzed to confirm the relationships between subvariables. Results Of the 374 patients, 311 (83.2%) exhibited normal pronunciation, 51 (13.6%) had VPI, and 12 (3.2%) were borderline. Primary cleft palate repair performed after 18 months was associated with a higher incidence of VPI than repair conducted before 18 months ( p = 0.005). The incidence of VPI was higher in cases of submucous cleft palate than in the other types based on the Veau classification ( p = 0.011). However, in the multivariable analysis, only the submucous type showed statistically significant results ( p = 0.026). Conclusion A total of 374 people underwent primary cleft palate repair, and 13.6% of those with VPI required secondary therapy. The incidence of VPI was relatively high among patients with primary cleft palate repair after 18 months and patients with submucous cleft palate.

Abstract
Traditional imaging modalities used to assess velopharyngeal insufficiency (VPI) do not allow for direct visualization of underlying velopharyngeal (VP) structures and musculature which could impact surgical planning. This limitation can be overcome via structural magnetic resonance imaging (MRI), the only current imaging tool that provides direct visualization of salient VP structures. MRI has been used extensively in research; however, it has had limited clinical use. Factors that restrict clinical use of VP MRI include limited access to optimized VP MRI protocols and uncertainty regarding how to interpret VP MRI findings. The purpose of this paper is to outline a framework for establishing a novel VP MRI scan protocol and to detail the process of interpreting scans of the velopharynx at rest and during speech tasks. Additionally, this paper includes common scan parameters needed to allow for visualization of velopharynx and techniques for the elicitation of speech during scans.

Abstract
OBJECTIVE To introduce a modified surgical method using bilateral buccinator flaps with posterior positioning of levator veli palatini muscles to treat velopharyngeal insufficiency. DESIGN Cross-sectional clinical study. PATIENTS Non-syndromic patients with velopharyngeal insufficiency. INTERVENTION We performed a modified surgical method using posterior positioning of levator veli palatini muscles and side-by-side bilateral buccinator flaps. MAIN OUTCOME MEASURES Patients' characteristics, severity of hypernasality, palatal lengthening size, and operative complications were recorded and described. The severity of hypernasality was determined by a speech therapist before and after the operation. RESULTS A total of 26 non-syndromic patients, with a median age of 8.5 years, were enrolled. All patients presented with severe hypernasality. Following the operation and during the follow-up period, 12 patients showed a complete resolution of hypernasality, while 9, 3, and 2 patients exhibited mild, moderate, and severe hypernasality, respectively. In addition, the mean palatal lengthening was measured to be 25.3 ± 3.5 mm. Overall, three patients experienced partial flap loss in one flap, which was successfully repaired with a secondary intention without the development of a fistula. In five cases, complete closure of the donor sites couldn't be achieved and thus were treated with secondary intention. Additionally, postoperative food restrictions were observed in seven cases but were resolved within one month. No other complications were noted in the remaining patients. CONCLUSION This modified palatal lengthening technique results in a significant lengthening of the palate while maintaining favorable speech outcomes. Future randomized clinical trials are warranted to validate our findings.

Differences in velopharyngeal pressures during speech sound production in patients with unilateral cleft lip and palate (UCLP) and healthy individuals. GERMAN MEDICAL SCIENCE : GMS E-JOURNAL 2024; 22:Doc02. [PMID: 38651020 PMCID: PMC11034380 DOI: 10.3205/000328] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Figures] [Subscribe] [Scholar Register] [Received: 07/15/2022] [Revised: 02/16/2023] [Indexed: 04/25/2024]
Abstract
Background During articulation the velopharynx needs to be opened and closed rapidly and a tight closure is needed. Based on the hypothesis that patients with cleft lip and palate (CLP) produce lower pressures in the velopharynx than healthy individuals, this study compared pressure profiles of the velopharyngeal closure during articulation of different sounds between healthy participants and patients with surgically closed unilateral CLP (UCLP) using high resolution manometry (HRM). Materials and methods Ten healthy adult volunteers (group 1: 20-25.5 years) and ten patients with a non-syndromic surgically reconstructed UCLP (group 2: 19.1-26.9 years) were included in this study. Pressure profiles during the articulation of four sounds (/i:/, /s/, /ʃ/ and /n/) were measured by HRM. Maximum, minimum and average pressures, time intervals as well as detection of a previously described 3-phase-model were compared. Results Both groups presented with similar pressure curves for each phoneme with regards to the phases described and pressure peaks, but differed in total pressures. An exception was noted for the sound /i:/, where a 3-phase-model could not be seen for most patients with UCLP. Differences in velopharynx pressures of 50% and more were found between the two groups. Maximum and average pressures in the production of the alveolar fricative reached statistical significance. Conclusions It can be concluded that velopharyngeal pressures of patients with UCLP are not sufficient to eliminate nasal resonance or turbulence during articulation, especially for more complex sounds. These results support a general understanding of hypernasality during speech implying a (relative) velopharyngeal insufficiency.

Modification of velopharyngeal closure pressures during phonation by neuromuscular electrical stimulation in healthy individuals. GERMAN MEDICAL SCIENCE : GMS E-JOURNAL 2024; 22:Doc03. [PMID: 38651019 PMCID: PMC11034089 DOI: 10.3205/000329] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Figures] [Subscribe] [Scholar Register] [Received: 02/23/2023] [Revised: 08/17/2023] [Indexed: 04/25/2024]
Abstract
Introduction Rhinophonia aperta may result from velopharyngeal insufficiency. Neuromuscular electrical stimulation (NMES) has been discussed in the context of muscle strengthening. The aim of this study was to evaluate in healthy subjects whether NMES can change the velopharyngeal closure pattern during phonation and increase muscle strength. Method Eleven healthy adult volunteers (21-57 years) were included. Pressure profiles were measured by high resolution manometry (HRM): isolated sustained articulation of /a/ over 5 s (protocol 1), isolated NMES applied to soft palate above motor threshold (protocol 2) and combined articulation with NMES (protocol 3). Mean activation pressures (MeanAct), maximum pressures (Max), Area under curve (AUC) and type of velum reactions were compared. A statistical comparison of mean values of protocol 1 versus protocol 3 was carried out using the Wilcoxon signed rank test. Ordinally scaled parameters were analyzed by cross table. Results MeanAct values measured: 17.15±20.69 mmHg (protocol 1), 34.59±25.75 mmHg (protocol 3) on average, Max: 37.86±49.17 mmHg (protocol 1), 87.24±59.53 mmHg (protocol 3) and AUC: 17.06±20.70 mmHg.s (protocol 1), 33.76±23.81 mmHg.s (protocol 3). Protocol 2 produced velum reactions on 32 occasions. These presented with MeanAct values of 13.58±12.40 mmHg, Max values of 56.14±53.14 mmHg and AUC values of 13.84±12.78 mmHg.s on average. Statistical analysis comparing protocol 1 and 3 showed more positive ranks for MeanAct, Max and AUC. This difference reached statistical significance (p=0.026) for maximum pressure values. Conclusions NMES in combination with articulation results in a change of the velopharyngeal closure pattern with a pressure increase of around 200% in healthy individuals. This might be of therapeutic benefit for patients with velopharyngeal insufficiency.

Various arrangements of pharyngeal flap in soft palate reconstruction after cancer treatment. Head Neck 2024. [PMID: 38426332 DOI: 10.1002/hed.27712] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2023] [Revised: 02/10/2024] [Accepted: 02/19/2024] [Indexed: 03/02/2024] Open
Abstract
BACKGROUND The pharyngeal flap (PF) is useful for reconstruction of soft palate defects, but effective arrangements of PF for various types of soft palate defects are controversial. Here, we classify three types of soft palate defects and discuss the arrangements of PF and their functional prognosis. METHODS Reconstruction was performed based on the classification of the defects. Clinical details were collected, and postoperative function was analyzed. RESULTS Eight patients were included in the study. The defect sizes ranged from 25 (width) × 40 (depth) to 40 × 60 mm. Six patients underwent pharyngeal flap reconstruction with free-flap reconstruction, and two underwent pharyngeal flap reconstruction. The pharyngeal flap was harvested at the maximum width of the posterior pharyngeal wall, ranging from 25 to 40 mm in length. Eating and speaking functions were maintained in all patients. CONCLUSIONS Good postoperative function can be maintained by narrowing the velopharyngeal space with a pharyngeal flap.

Abstract
Speech is the most basic yet invaluable mode of expression for an individual. Alterations in speech can have vast effects on the psychological well-being of a person, hampering social interactions. Congenital or traumatic defects of the hard and soft palate result in velopharyngeal dysfunction, which often results in abnormal and aberrant speech. Apart from these, it is also a common outcome following surgical repair of cleft palate. Prosthodontic management of such cases with velopharyngeal obturators to improve speech and function is well documented and known to give optimal results. In this case report, we are presenting the rehabilitation of residual velopharyngeal insufficiency post-cleft palate closure using a speech bulb prosthesis attached to a complete denture. As the speech bulb would add to the weight of the existing prosthesis, a hollow complete denture was planned. The prosthesis resulted in a decrease in nasal air emissions and hypernasality, thus improving the patient's communication skills and overall quality of life.

Abstract
PURPOSE A palatal fistula is an adverse outcome of cleft palate repair. It is unknown if a palatal fistula will influence velopharyngeal closure, even after repair of the fistula. This study determines the effect of a soft palate fistula on the risk of developing velopharyngeal insufficiency. METHODS A retrospective chart review was conducted on patients who underwent primary cleft palate repair between 2000 and 2015, with complete records at 4 years of age. Fistulae involving the secondary palate following primary palatoplasty were classified as the soft or hard palate. A forced-entry multivariate logistic regression model was built to detect predictors of velopharyngeal dysfunction. RESULTS Records of 329 patients were analyzed with a mean follow-up of 8.7 years. A palatal fistula was identified in 89/329 patients (27%) and 29/329 patients (9%) underwent an independent fistula repair. Of the patients with fistula, 44% were located in the hard palate only and 56% had soft palate involvement. Compared to patients without a fistula, rates of velopharyngeal dysfunction were significantly higher in patients with a fistula involving the soft palate (OR 3.875, CI: 1.964-7.648, P < .001) but not in patients with a hard palate fistula (OR 1.140, CI: 0.497-2.613, P = .757). Veau class, age at primary repair, and syndromic status were not significant predictors of VPI (0.128≤P ≤ .975). CONCLUSIONS A palatal fistula involving the soft palate is a significant predictor for development of velopharyngeal dysfunction after primary palatoplasty. Surgical intervention, at the time of fistula repair, to add vascularized tissue may be indicated to prophylactically decrease the risk of velopharyngeal dysfunction.

Abstract
OBJECTIVES The clinical effects and surgical procedures of Hogan posterior pharyngeal flap in the treatment of the older patients with velopharyngeal insufficiency (VPI) after cleft palate repair were investigated. METHODS A total of 33 patients (aged 10-35 years; average of 20.4 years) with VPI secondary to cleft palate were included. They underwent Hogan posterior pharyngeal flap to improve velopharyngeal closure function. The clinical efficacy of the ope-ration was evaluated with Chinese speech clarity measurement and nasopharyngeal fiberscope (NPF), and the velopharyngeal closure was graded. The average follow-up time was 13.3 months. RESULTS The wounds of all patients were healed by first intention, and speech assessment showed that the consonant articulation increased and the rate of hypernasality and nasal emission decreased significantly (P<0.05). NPF examination showed that the postoperative velopharyngeal closure function significantly improved, 30 cases (91%) were gradeⅠ, and 3 cases (9%) were grade Ⅱ. CONCLUSIONS Hogan posterior pharyngeal flap for VPI secondary to cleft palate can significantly improve velopharyngeal closure.

Abstract
Velopharyngeal insufficiency (VPI), which is the incomplete closure of the velopharyngeal valve during speech, is a typical poor outcome that should be evaluated after cleft palate repair. The interpretation of VPI considering both imaging analysis and perceptual evaluation is essential for further management. The authors retrospectively reviewed patients with repaired cleft palates who underwent assessment for velopharyngeal function, including both videofluoroscopic imaging and perceptual speech evaluation. The final diagnosis of VPI was made by plastic surgeons based on both assessment modalities. Deep learning techniques were applied for the diagnosis of VPI and compared with the human experts' diagnostic results of videofluoroscopic imaging. In addition, the results of the deep learning techniques were compared with a speech pathologist's diagnosis of perceptual evaluation to assess consistency with clinical symptoms. A total of 714 cases from January 2010 to June 2019 were reviewed. Six deep learning algorithms (VGGNet, ResNet, Xception, ResNext, DenseNet, and SENet) were trained using the obtained dataset. The area under the receiver operating characteristic curve of the algorithms ranged between 0.8758 and 0.9468 in the hold-out method and between 0.7992 and 0.8574 in the 5-fold cross-validation. Our findings demonstrated the deep learning algorithms performed comparable to experienced plastic surgeons in the diagnosis of VPI based on videofluoroscopic velopharyngeal imaging.

Abstract
Velopharyngeal insufficiency is a complex condition with various treatment options. In this case, a patient with a cleft palate who was treated for velopharyngeal insufficiency with calcium hydroxyapatite injection pharyngoplasty developed persistent cervical pain on postoperative day 6. CT imaging showed a hypodense structure in the right retropharyngeal tissue, and cultures tested positive for Streptococcus intermedius and Staphylococcus aureus. An MRI later revealed skull base osteomyelitis. The infection was controlled via surgical intervention and antibiotics. This case highlights potential severe complications from injection pharyngoplasty and it underscores the importance of early recognition and management of infectious complications.

Abstract
OBJECTIVE Patients with 22q11.2 deletion syndrome (22q11DelS) often present with velopharyngeal dysfunction (VPD). VPD in patients with 22q11DelS is multifactorial beyond velopharyngeal insufficiency (VPI) alone, and differences in surgical outcomes are poorly understood. Our objective was to determine whether patients with 22q11DelS have an increased risk for persistent VPI after sphincter pharyngoplasty compared to patients without 22q11DelS. METHODS We completed a retrospective cohort study of patients with 22q11DelS undergoing sphincter pharyngoplasty between 1995 and 2019 using a VPD clinic database. Patients with 22q11DelS were compared to a cohort of 2:1 frequency-matched (age, degree of velopharyngeal closure) patients without 22q11DelS. Variables included patient characteristics, surgical history, perceptual speech evaluation, and degree of closure on nasopharyngoscopic evaluations. Primary outcomes included postoperative VPI severity and hypernasality. Speech and nasopharyngoscopic characteristics were compared using Fisher's exact test. Postoperative VPI severity and hypernasality were compared between groups via relative risks (RR) from mixed effects Poisson regression models, with random effects of age and velopharyngeal closure. RESULTS 134 patients (51 22q11DelS, 83 matched) were included, with mean age of 7.3 years (standard deviation 3.0) and 50% male. Cohorts had similar preoperative speech characteristics and nasopharyngoscopic findings. Patients with 22q11DelS had similar postoperative VP function as patients without 22q11DelS (RR 0.85, CI 0.46-1.57 for VPI severity, RR 0.83, CI 0.45-1.53 for hypernasality). Even after adjusting by preoperative variables, no differences were seen between both groups. CONCLUSION Matched for age and pre-operative velopharyngeal closure, patients with and without 22q11DelS and VPI had similar benefits after sphincter pharyngoplasty. LEVEL OF EVIDENCE Non-randomized controlled cohort study, 3 Laryngoscope, 133:2813-2820, 2023.

Abstract
BACKGROUND Submucous cleft palate (SMCP) requires surgical repair if symptomatic. The Furlow double-opposing Z-plasty is the preferred method in Helsinki cleft center. AIMS To assess the efficacy and complications of Furlow Z-plasty in the treatment of symptomatic SMCP. METHODS This retrospective study reviewed documentation of 40 consecutive patients with symptomatic SMCP who underwent primary Furlow Z-plasty by 2 high-volume cleft surgeons at a single center between 2008 and 2017. Patients underwent perceptual and instrumental evaluation of velopharyngeal function (VPF) by speech pathologists preoperatively and postoperatively. RESULTS The median age at Furlow Z-plasty was 4.8 years (SD 2.6, range 3.1-13.6). The overall success rate, including postoperative competent or borderline competent VPF, was 83%, and 10% required secondary surgery for residual velopharyngeal insufficiency. The success rate was 85% in nonsyndromic, and 67% in syndromic patients with no significant difference ( P =0.279). Complications arose in only 2 (5%) patients. No children were found to have obstructive sleep apnea postoperatively. CONCLUSION Furlow primary Z-plasty is a safe and effective operation for symptomatic SMCP with a success rate of 83% with only 5% rate of complications.

Effect of perceptive-auditory training on the classification of speech hypernasality. Codas 2023; 35:e20220069. [PMID: 37729318 PMCID: PMC10723581 DOI: 10.1590/2317-1782/20232022069pt] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/19/2022] [Accepted: 04/01/2023] [Indexed: 09/22/2023] Open
Abstract
PURPOSE To analyze the effect of auditory-perceptual training by inexperienced speech-language pathologists in the classification of hypernasality in individuals with cleft lip and palate and compare their classification of hypernasality individually, with the gold standard evaluation, before and after this training. METHODS Three inexperienced speech-language pathologists used a four-point scale to assess 24 high-pressure speech samples from individuals with cleft lip and palate, before and after auditory-perceptual training. The speech samples corresponded to six samples of each degree of hypernasality. The speech-language pathologists received auditory-perceptual training during the assessments. They had access to anchor samples and immediate feedback of correct answers regarding the degree of hypernasality in training. RESULTS There was no significant difference in the overall percentage of correct answers when comparing before and after the auditory-perceptual training. There was a significant association and agreement of the three evaluators with a gold standard evaluation after training, with an increase in agreement for a single evaluator for absent and mild degrees of hypernasality. The dichotomous analysis of the data showed an increase in the Kappa Index of Agreement of this evaluator. Although there was an increase in the Index of Agreement between evaluators for absent, mild, and severe hypernasality, this increase did not reach statistical significance. CONCLUSION The auditory-perceptual training provided did not result in a significant improvement in the hypernasality classification for the inexperienced speech-language pathologists, even though the individual data analysis showed that the training favored one of the evaluators. Further studies involving gradual and more extensive auditory-perceptual training may favor the classification of hypernasality by inexperienced SLPs.

Effects of multitasker babble noise on speech intelligibility in children with velopharyngeal insufficiency (VPI). INTERNATIONAL JOURNAL OF LANGUAGE & COMMUNICATION DISORDERS 2023; 58:1814-1828. [PMID: 37294086 DOI: 10.1111/1460-6984.12913] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/12/2022] [Accepted: 05/16/2023] [Indexed: 06/10/2023]
Abstract
BACKGROUND Intelligibility measurement is influenced by the characteristics of a speaker, listener and contextual factors. This study addresses the clinical problem of measuring speech intelligibility in children with velopharyngeal insufficiency (VPI) in real-world conditions. AIMS The purpose of the study was to investigate the effects of background noise on speech intelligibility in speakers with velopharyngeal insufficiency (VPI) compared to typical speech. The study further determined the contribution of nasalance and articulation accuracy in judgments of intelligibility. METHODS & PROCEDURES Fifteen speakers diagnosed with VPI and their typical peers provided audio recordings of 20 sentences from the Hearing in Noise Test. Speech samples were presented over quiet and noise (+5 dB signal-to-noise ratio) conditions to 70 naïve listeners. Intelligibility scores from naïve listeners' orthographic transcriptions were obtained as the percentage of correctly identified words. OUTCOMES & RESULTS A repeated-measures analysis of variance showed diagnosis of VPI (F(1, 28) = 13.44, p = 0.001, and presence of noise (F(1, 28) = 39.18, p < 0.001) significantly affected the intelligibility scores. There was no interaction between the diagnosis of VPI and noise (F(1, 28) = 0.06, p = 0.80). The multivariate regression analysis indicated that nasalance and articulation accuracy explain a significant amount of variance in the intelligibility scores of VPI speakers in quiet (F(2, 12) = 7.11, p < 0.05, R2 = 0.55, R2 Adjusted = 0.47) and noise (F(2, 12) = 6.32, p < 0.05, R2 = 0.51, R2 Adjusted = 0.43), but the significance mainly came from the effect of percentage of consonants correct (β = 0.97, t(12) = 2.90, p = 0.01). Percentage of consonants correct significantly increased the speech intelligibility in either with or without noise conditions. CONCLUSIONS & IMPLICATIONS The current work suggests that background noise will significantly affect reductions in intelligibility in both groups; the effect is more prominent in VPI speech. It was also further noted that articulation accuracy significantly affected intelligibility in quiet and noise rather than nasalance scores. WHAT THIS PAPER ADDS What is already known on the subject Intelligibility measurement is influenced by the characteristics of a speaker, listener and contextual factors. Accordingly, it is essential to determine the degree to which speech assessments in the clinic can predict communication difficulties in the presence of background noise in real life. Background noise can adversely cause speech intelligibility degradation in individuals with speech disorders. What this study adds The study examined the effects of background noise on speech intelligibility in speakers with velopharyngeal insufficiency (VPI) secondary to cleft palate compared to typical speech. The study results suggested that the presence of background noise will significantly affect reductions in intelligibility in both groups; however, the effect is more prominent in VPI speech. What are the clinical implications of this work? We found out that the intelligibility of VPI speech is lower in the presence of background noise, and therefore, assessments of speech intelligibility in clinical settings should take this into account. To ensure effective communication in noisy environments, recommended strategies include selecting quiet locations, eliminating potential distractions and supplementing communication with nonverbal cues. It is important to recognize that the effectiveness of these strategies may vary depending on the individual and the specific communication context.

[PMID: 37646567 PMCID: PMC10445635 DOI: 10.1097/scs.0000000000009555] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2021] [Accepted: 05/19/2023] [Indexed: 09/01/2023] Open
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.

How differences in anatomy and physiology and other aetiology affect the way we label and describe speech in individuals with cleft lip and palate. INTERNATIONAL JOURNAL OF LANGUAGE & COMMUNICATION DISORDERS 2023. [PMID: 37650488 DOI: 10.1111/1460-6984.12946] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/16/2023] [Accepted: 07/31/2023] [Indexed: 09/01/2023]
Abstract
BACKGROUND Speech in individuals with cleft lip and/or palate (CLP) is a complex myriad of presenting symptoms. It is uniquely associated with the structural difference of velopharyngeal insufficiency (VPI), together with a wide and heterogeneous range of other aetiologies which often co-occur. The nature of the speech sound disorder (SSD) including VPI may also change over the course of an individual's care pathway. Differences in terminology and approaches to analysis are currently used, resulting in confusion internationally. Additionally, current diagnostic labels and classification systems in SSD do not capture the complexity and full nature of speech characteristics in CLP. AIMS This paper aims to explore the different aetiologies of cleft palate/VPI speech and to relate aetiology with speech characteristic(s). In so doing, it attempts to unravel the different terminology used in the field, describing commonalities and differences, and identifying overlaps with the speech summary patterns used in the United Kingdom and elsewhere. The paper also aims to explore the applicability of current diagnostic labels and classification systems in the non-cleft SSD literature and illustrate certain implications for speech intervention in CLP. METHODS AND PROCEDURES The different aetiologies were identified from the literature and mapped onto cleft palate/VPI speech characteristics. Different terminology and approaches to analysis are defined and overlaps described. The applicability of current classification systems in SSD is discussed including additional diagnostic labels proposed in the field. OUTCOMES AND RESULTS Aetiologies of cleft palate/VPI speech identified include developmental (cognitive-linguistic), middle ear disease and fluctuating hearing loss, altered oral structure, abnormal facial growth, VPI-structural (abnormal palate muscle) and VPI-iatrogenic (maxillary advancement surgery). There are four main terminologies used to describe cleft palate/VPI speech: active/passive and compensatory/obligatory, which overlap with the four categories used in the UK speech summary patterns: anterior oral cleft speech characteristics (CSCs), posterior oral CSCs, non-oral CSCs and passive CSCs, although not directly comparable. Current classification systems in non-cleft SSD do not sufficiently capture the full nature and complexity of cleft palate/VPI speech. CONCLUSIONS AND IMPLICATIONS Our attempt at identifying the heterogeneous range of aetiologies provides clinicians with a better understanding of cleft palate/VPI speech to inform the management pathway and the nature and type of speech intervention required. We hope that the unravelling of the different terminology in relation to the UK speech summary patterns, and those used elsewhere, reduces confusion and provides more clarity for clinicians in the field. Diagnostic labels and classification require international agreement. WHAT THIS PAPER ADDS What is already known on the subject Speech associated with cleft palate/velopharyngeal insufficiency (VPI) is a complex myriad of speech characteristics with a wide and heterogeneous range of aetiologies. Different terminology and speech summary patterns are used to describe the speech characteristics. The traditional classification of cleft palate/VPI speech is Articulation Disorder, although evidence is building for Phonological Disorder and contrastive approaches in cleft speech intervention. What this paper adds to existing knowledge This paper explores the range of aetiologies of cleft palate/VPI speech (e.g., altered oral structure, abnormal facial growth, abnormal palate muscle and iatrogenic aetiologies) and attempts to relate aetiology with speech characteristic(s). An attempt is made at unravelling the different terminology used in relation to a well-known and validated approach to analysis, used in the United Kingdom and elsewhere. Complexities of current diagnostic labels and classifications in Speech Sound Disorder to describe cleft palate/VPI speech are discussed. What are the potential or actual clinical implications of this work? There needs to be a common language for describing and summarising cleft palate/VPI speech. Speech summary patterns based on narrow phonetic transcription and correct identification of aetiology are essential for the accurate classification of the speech disorder and identification of speech intervention approaches. There is an urgent need for research to identify the most appropriate type of contrastive (phonological) approach in cleft lip and/or palate.

Automatic Detection System for Velopharyngeal Insufficiency Based on Acoustic Signals from Nasal and Oral Channels. Diagnostics (Basel) 2023; 13:2714. [PMID: 37627973 PMCID: PMC10453249 DOI: 10.3390/diagnostics13162714] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2023] [Revised: 08/18/2023] [Accepted: 08/19/2023] [Indexed: 08/27/2023] Open
Abstract
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.

Abstract
OBJECTIVE Surgical treatment of velopharyngeal insufficiency (VPI) includes a wide array of procedures. The purpose of this study was to develop a classification for VPI procedures and to describe variations in how they are performed.Design/participants/setting/outcomes: We completed an in-depth review of the literature to develop a preliminary schema that encompassed existing VPI procedures. Forty-one cleft surgeons from twelve hospitals across the USA and Canada reviewed the schema and either confirmed that it encompassed all VPI procedures they performed or requested additions. Two surgeons then observed the conduct of the procedures by surgeons at each hospital. Standardized reports were completed with each visit to further explore the literature, refine the schema, and delineate the common and unique aspects of each surgeon's technique. RESULTS Procedures were divided into three groups: palate-based surgery; pharynx-based surgery; and augmentation. Palate-based operations included straight line mucosal incision with intravelar veloplasty, double-opposing Z-plasty, and palate lengthening with buccal myomucosal flaps. Many surgeons blended maneuvers from these three techniques, so a more descriptive schema was developed classifying the maneuvers employed on the oral mucosa, nasal mucosa, and muscle. Pharynx-based surgery included pharyngeal flap and sphincter pharyngoplasty, with variations in design for each. Augmentation procedures included palate and posterior wall augmentation. CONCLUSIONS A comprehensive schema for VPI procedures was developed incorporating intentional adaptations in technique. There was substantial variation amongst surgeons in how each procedure was performed. The schema may enable more specific evaluations of surgical outcomes and exploration of the mechanisms through which these procedures improve speech.

Does pharyngoplasty work? Outcomes of 100 consecutive operations over 10 years. ANZ J Surg 2023; 93:1944-1949. [PMID: 37283293 DOI: 10.1111/ans.18563] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2023] [Revised: 05/22/2023] [Accepted: 05/28/2023] [Indexed: 06/08/2023]
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.

Comparison of intelligibility measures for children with velopharyngeal insufficiency: visual analog scale ratings, interval scales, and orthographic transcription (OT)-based measures. CLINICAL LINGUISTICS & PHONETICS 2023:1-19. [PMID: 37363955 DOI: 10.1080/02699206.2023.2227987] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/13/2022] [Revised: 05/17/2023] [Accepted: 06/16/2023] [Indexed: 06/28/2023]
Abstract
Regardless of the underlying cause for speech impairment in speakers with cleft palate, a universal consequence of cleft palate is reduced speech intelligibility. Still, there is no standardised approach for measuring intelligibility for speakers with cleft speech. The current study aimed to determine the relationship between orthographic transcription (OT)-based measures, interval-scale ratings, and visual analog scale (VAS) ratings for perceptual judgements of intelligibility in speakers with cleft palate as judged by speech-language pathologists (SLPs). The speaker participants were six speakers with velopharyngeal insufficiency secondary to cleft palate. Four sets of sentences from the Hearing in Noise Test were recorded from each speaker. A total of 14 SLPs provided their intelligibility judgement on these speaker's recordings by word-by-word orthographic transcriptions, a visual analog scale (0-100), and a 5-point interval rating scale. A Spearman rank correlation test indicated a negative, strong correlation between OT-based measurements and VAS scores (r = -.94; p = 0.01) and between OT-based measurements and interval rating scores (r = -.77, p = 0.01). A strong, positive correlation was found between scores obtained from VAS and interval rating scales (r = .83, p = 0.05). The strong relationship between the objective measure of intelligibility (i.e. OT-based measure) and a subjective measure of intelligibility (i.e. VAS and interval scale) supports using a less time-consuming VAS as a substitute for orthographic transcription in measuring intelligibility in cleft palate speech.

Abstract
Background and objectives: Bipolar electrocautery is commonly used to control bleeding after cold-instrument pediatric adenoidectomy, but the surgeon should be aware of the possible side effects. OBJECTIVE: The aim of our study is to investigate the effects of bipolar electrocautery when used for bleeding control at the end of an adenoidectomy procedure. Materials and Methods: We evaluated the effect of electrocautery on postoperative pain, velopharyngeal insufficiency symptoms, postoperative nasal obstruction, and rhinorrhea in a group of 90 children undergoing adenoidectomy in our ENT department over a period of 3 months. Results: After statistically analyzing the data, we found that the duration of postoperative pain, the duration of rhinorrhea and nasal obstruction, and the duration of painkiller administration, as well as the velopharyngeal insufficiency symptoms, were significantly longer in patients in whom electrocautery was used for hemostasis. A significantly higher incidence of posterior neck pain and halitosis (oral malodor) was noted in the patients in whom electrocautery was used for adenoidectomy hemostasis. Conclusions: Bipolar electrocautery use should be limited during pediatric adenoidectomy hemostasis because of the possible side effects: longer postoperative pain, prolonged nasal obstruction, rhinorrhea and velopharyngeal insufficiency, and halitosis. We noted some side effects that were specific to electrocautery use during adenoidectomy: posterior neck pain and oral malodor. Acknowledging the risk for these symptoms can help to alleviate the anxiety of both the parents and the patients regarding the expected postoperative outcomes.

Abstract
OBJECTIVE To explore the incidence of postoperative complications and investigate the impact of preselected factors on functional and quality of life outcomes following the Sommerlad-Furlow modified palatoplasty technique. STUDY DESIGN Retrospective cohort. METHODS A total of 429 patients with cleft palate, who received Sommerlad-Furlow modified technique between 2011-2017 were enrolled. The postoperative complications including oronasal fistula (ONF), velopharyngeal insufficiency (VPI), and inadequate quality of life (QOL) were collected. Data of preselected factors including gender, age at palatoplasty, cleft type, cleft width, palatal width, pharyngeal cavity depth, and operation duration were also collected. RESULTS Among 429 patients, 40.1% were males whereas 59.9% were females. The mean age at palatoplasty was 1.23 ± 0.69 (0.42-4) years, and the average cleft width was 10.15 ± 2.95 (4-27) mm. The cleft types had recorded rates of about 6.8%, 69.5%, 17.7%, and 6.1% of Veau I, II, III, and IV, respectively. The overall incidence rates of ONF, VPI, and inadequate QOL were 2.3%, 19.4%, and 31.3%, respectively. In both the univariate and multivariate analyses, the cleft type was significantly implicated in ONF formation (p = 0.023 and 0.032, respectively) whereas the velopharyngeal function was impacted by the palatoplasty age (p ˂ 0.001). The receiver operating characteristic curve indicated that age of palatoplasty ≥1.3 years (area under the curve = 0.611, p = 0.002) was the cutoff value for predicting the incidence of VPI. CONCLUSIONS The Sommerlad-Furlow modified technique appears to have appropriate postoperative outcomes, even in the wide cleft palate. The older age at palatoplasty has a major impact on the overall postoperative outcomes. LEVEL OF EVIDENCE 4 Laryngoscope, 133:822-829, 2023.

Abstract
To determine the sensitivity and specificity of velar notching seen on nasopharyngoscopy for levator veli palatini (LVP) muscle discontinuity and anterior positioning. Nasopharyngoscopy and MRI of the velopharynx were performed on patients with VPI as part of their routine clinical care. Two speech-language pathologists independently evaluated nasopharyngoscopy studies for the presence or absence of velar notching. MRI was used to evaluate LVP muscle cohesiveness and position relative to the posterior hard palate. To determine the accuracy of velar notching for detecting LVP muscle discontinuity, sensitivity, specificity, and positive predictive value (PPV) were calculated. A craniofacial clinic at a large metropolitan hospital. PARTICIPANTS Thirty-seven patients who presented with hypernasality and/or audible nasal emission on speech evaluation and completed nasopharyngoscopy and velopharyngeal MRI study as part of their preoperative clinical evaluation. Among patients with partial or total LVP dehiscence on MRI, presence of a notch accurately identified discontinuity in the LVP 43% (95% CI 22-66%) of the time. In contrast, the absence of a notch accurately indicated LVP continuity 81% (95% CI 54-96%) of the time. The PPV for the presence of notching to identify a discontinuous LVP was 78% (95% CI 49-91%). The distance from the posterior edge of the hard palate to the LVP, known as effective velar length, was similar in patients with and without notching (median 9.8 mm vs 10.5 mm, P = 1.00). The observation of a velar notch on nasopharyngoscopy is not an accurate predictor of LVP muscle dehiscence or anterior positioning.

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

Abstract
Augmentation pharyngoplasty, in which tissue filler or grafts are used to augment the posterior nasopharynx, is an accepted option to treat velopharyngeal insufficiency. It is generally well tolerated and safe with limited side effects. In this study, we describe a case of a retropharyngeal abscess and Grisel syndrome following hyaluronic acid augmentation pharyngoplasty. Grisel syndrome is a serious condition that requires early diagnosis and prompt intervention to prevent further complications. Velopharyngeal insufficiency (VPI) can be treated conservatively by speech therapy or surgically by augmentation pharyngoplasty and pharyngeal surgeries. Augmentation pharyngoplasty is safe and well‐tolerated procedure. We report a very rare complication of this procedure which is retropharyngeal abscess and Grisel syndrome (GS). GS is a serious condition that requires early diagnosis and prompt intervention to prevent further neurological complications.

Abstract
PURPOSE The present study is aimed towards determining and comparing normative nasalance scores in Chilean Spanish-speaking adult men and women. METHODS 40 women (age range 18 to 35, X = 25.79, SD = 5.83) and 36 men (age range 18 to 35, X = 26.45, SD = 4.08) were invited to participate, all of them without any previous speech therapy, neurological pathologies, intellectual deficits, hearing loss, syndromes, or other diagnosed pathologies that could impact speech production.A study of proper velopharyngeal function was performed, using a perceptual resonance evaluation. Nasalance was determined using a model 6450 Nasometer, during the reading of three standardized speech samples in Spanish: a nasal passage (NP), an oronasal passage (ONP), and an oral passage (OP). Also, the nasalance distance was calculated. Genders were compared using Wilcoxon tests for independent samples. RESULTS The NP presented the highest percentage of nasalance, with 52.13% (± 4.73), followed by the ONP with 25.38% (± 3.7), and finally the OP, which presented the lowest value of 14.15% (± 5.03). Meanwhile, nasalance distance was 37.98% (± 5.32). Finally, no significant differences were observed when comparing the nasalance between genders (p >0.05). CONCLUSION The nasalance values obtained were similar to those observed for other Spanish speakers. Also, male and women showed similar scores. The results of this study are a contribution to the indirect assessment of velopharyngeal function in Chilean adults.

Abstract
OBJECTIVE Assessment of the hypothesized correlation between the Chinese Velopharyngeal Insufficiency (VPI) Effects on Life Outcomes (VELO) instrument and measured speech parameters. METHODS A cross-sectional study was conducted in the Oral Clefts Center of West China Hospital of Stomatology between January 2019 and December 2019. Speech parameters including speech intelligibility deficit, VPI severity, VP gap, and need for speech therapy were evaluated by speech-language pathologists. All patients and their parents completed the VELO instrument. The correlation between aforementioned speech parameters and VELO scores was examined utilizing Spearman correlation coefficients. The reliability of VELO test-retest and parent proxy assessment was estimated utilizing intraclass correlation coefficients (ICC). A receiver operating characteristic curve was used to calculate the cutoff VELO score. RESULTS One hundred and forty patients with their parents were enrolled. The mean age was 12.58 ± 3.72 years. Both parent and youth VELO total and domain scores recorded moderate to strong correlations with all speech parameters (r > -.40, P ˂ .001) except the swallowing domain. Most VELO domain items have shown significant correlations with at least one speech parameter. Moreover, the scales of all speech parameters showed different VELO scores (P ˂ .001). The ICC reported test-retest correlation >.73 in all domains, and parent proxy correlation >.63 in most domains except the emotional and perception domains. The cutoff VELO score was 79.04 in parent version and 85.77 in youth version. CONCLUSIONS The correlations between VELO scores and measured speech parameters have provided evidence for test-retest and parent proxy reliability and criterion and construct validity of the Chinese version of the VELO instrument. A VELO score ≥79.04 (in parent version) or ≥85.77 (in youth version) mostly reflects proper speech-related quality of life. Hence, this instrument could serve as a simple tool to help clinicians understand the social, emotional, and physical influences of VPI.

Facial grimace during speech in cleft lip and palate: a proposal for classification. Codas 2022; 34:e20210069. [PMID: 35019087 PMCID: PMC9769419 DOI: 10.1590/2317-1782/20212021069] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2021] [Accepted: 08/03/2021] [Indexed: 02/03/2023] Open
Abstract
PURPOSE To investigate the effectiveness of a proposal for classification of facial grimace (FG) and its correlation with objective evaluation of velopharyngeal closure (VPC). METHODS Twenty individuals with repaired cleft lip and palate underwent velopharyngeal area measurement by means of rhinomanometry and speech sample recording. The FG was rated in two steps, by three speech-language pathologists. First the evaluators rated the FG using their own criteria as: 1= absent FG; 2=mild; 3=moderate; 4=severe. Subsequently, they were submitted to a training session that established the following FG rating criteria: 1=absent FG; 2=movement only of the nose or upper third of the face; 3=strong movement of the nose or upper third of the face; 4=movement of the nose and upper third of the face. The evaluators rated the FG using the established criteria. Intra- and inter-rater agreement were calculated using weighted Kappa coefficient. Correlation between the two stage ratings with the VPC was calculated by Spearman's correlation coefficient. RESULTS In the first stage inter-rater agreement ranged from fair to substantial; in the second stage, from substantial to almost perfect. Intra-rater agreement ranged from moderate to almost perfect in the first stage, and from moderate to substantial in the second stage. The correlation between FG and velopharyngeal area was positive and significant in both stages. CONCLUSION The proposed FG judgement proved to be effective in determining the symptom and reliable in diagnosing the severity of velopharyngeal dysfunction. The significant correlation between perceptual and instrumental methods suggests that FG can be used in predicting VPC.

Abstract
INTRODUCTION Furlow double-opposing Z-plasty (DOZ) lengthens the soft palate; however, this lengthening is achieved at the expense of increased mucosal flap tension. Thus, its use is limited in patients with severe tension applied on mucosal flap after DOZ. In this study, DOZ was combined with a buccal fat pad (BFP) flap to maximize palatal lengthening and muscle repositioning. METHODS This study included patients who underwent surgical correction for velopharyngeal insufficiency between December 2016 and February 2019. Patients with more than moderate degree hypernasality following primary palatoplasty were included in the study. Patients younger than 4 years of age, those with a submucous cleft palate, or syndromic patients were excluded. Speech outcomes were investigated for those who underwent DOZ only (DOZ group, n = 17) and those in whom a BFP was used (BFP group, n = 15) pre- and postoperatively. The velopharyngeal gaps between the uvula and pharyngeal wall were measured before and immediately after surgery to estimate the palatal length. RESULTS Most patients who received a BFP showed improvement in hypernasality. However, the hypernasality of the DOZ group was more severe than that of the BFP group (p = 0.023). The extent of palatal lengthening was 4.4 ± 1.7 mm and 7.5 ± 2.1 mm in the DOZ and BFP groups, respectively (p = 0.001). CONCLUSIONS BFPs reduced the tension of the DOZ mucosal flap and maximized palatal lengthening and muscle repositioning. They promoted velopharyngeal closure in patients with moderate and moderate-to-severe velopharyngeal insufficiency. Hence, our method improves the surgical outcomes of patients with velopharyngeal insufficiency after primary palatoplasty.

Abstract
OBJECTIVES This study aims to investigate the incidence and severity of obstructive sleep apnea (OSA) in cleft patients with velopharyngeal insufficiency (VPI) after pharyngeal flap surgery (PFS) and explore the influence of operation age. METHODS A retrospective study was conducted in 82 cleft patients after PFS. The patients were divided into two groups according to their age at the time of surgery. The incidence and severity of OSA were assessed at least 1.2 years (mean 6.0 years) postoperatively by polysomnography (PSG). RESULTS The incidence rates of OSA were 20% in the adult group and 31% in the child group. No significant difference was found between the two groups (P=0.289). Patients with OSA in the adult and child groups were classified into different levels of severity (mild, moderate, severe) according to the apnea hypoventilation index (AHI). No statistically significant difference in the severity of OSA was found between the two groups (P=0.079). CONCLUSIONS Some patients still have OSA average of 6.0 years after PFS, and operation ageis unrelated to the incidence and severity of OSA.

Abstract
OBJECTIVE To determine predictors of success following Veau 1 and 2 cleft palate repair in patients with and without syndromes. STUDY DESIGN Retrospective review of prospectively collected data. SETTING Tertiary care children's hospital. METHODS All children <18 months of age undergoing Furlow palatoplasty for Veau 1 and 2 cleft repair between 2000 and 2014 with postoperative perceptual speech assessment (PSA). RESULTS In total, 368 consecutive patients were identified; 95 were excluded, resulting in 273 patients. Median age at surgery was 13.0 months (interquartile range [IQR], 11-15 months) with postoperative PSA at a median of 32.3 months (IQR, 26.3-44.5 months). Fifty patients (18.3%) had syndrome diagnosis; 59 patients (21.6%) had nonsyndromic Robin sequence. Velopharyngeal insufficiency (VPI) occurred in 27 patients (10.5%); 13 underwent secondary speech surgery. Cleft-related speech errors occurred in 46 patients (17.6%). Non-cleft-related speech errors occurred in 155 patients (59.6%) and reduced intelligibility in 127 patients (47.9%). Oronasal fistula occurred in 23 patients (8.8%) and was exclusive to Veau 2 clefts. In multivariate analysis, age >13 months at palatoplasty demonstrated a 6-fold higher rate of VPI (hazard ratio [HR], 6.64; P < .01), worse speech outcomes (HR, 6.04; P < .01; HR, 1.60; P < .01; HR, 1.57; P = .02), and greater speech therapy utilization (HR, 2.18; P < .01). CONCLUSION VPI occurred in 10% of patients undergoing Furlow palatoplasty repair of Veau 1 or 2 clefts. Age <13 months at palatoplasty was associated with improved speech outcomes and lower VPI incidence (2.8% vs 16.2%). Syndromic diagnosis was associated with noncleft speech errors and reduced intelligibility on univariate analysis but not velopharyngeal function after palatoplasty.

Abstract
OBJECTIVES (1) To determine the incidence rate of velopharyngeal dysfunction (VPD) according to 7 speech criteria post-Furlow palatoplasty. (2) To find an anatomical measurement of the cleft palate (or combination of measurements) associated with the occurrence of VPD. STUDY DESIGN Retrospective cohort study. PARTICIPANTS AND METHODS Fifty-six patients with cleft palate ± cleft lip underwent palatoplasty with the Furlow technique at the age of 10 months. Pre-and post-palatoplasty cleft palate measurements were collected during the procedure. Three blinded speech-language pathologists (SLPs) retrospectively scored the patients from the chart data at age 4. Student t test and receiver operating characteristic curve analysis were used to evaluate the association and predictive capacity between cleft measurements and parameters (M&P) with all VPD criteria. RESULTS The SLPs found an incidence of VPD according to 7 criteria: hypernasality (11%), audible nasal emission (4%), nasal rustle (14%), compensatory errors (4%), impairment of speech understandability (7%), and impairment of speech acceptability (16%). The SLPs recommended a secondary surgical procedure in 5 patients (9%). A statistically significant association was found between, respectively, 17 and 5 M&P and the occurrence of compensatory errors and audible nasal emission. Our data suggest that the length of the cleft, the cleft area, and the postoperative transversal size of the nasopharynx are the best indicators of the future positivity of VPD criteria. CONCLUSION The size of the postoperative transverse nasopharyngeal area during the primary cleft palate procedure may become the focus of the next generation of cleft surgeons to reduce the incidence of VPD.

Abstract
Velopharyngeal insufficiency (VPI) results from defects interfering with closure of the velopharyngeal port. It can lead to many issues ranging from nasal regurgitation to severe speech abnormalities. Treatment is tailored to patient-specific etiology and severity, often involving surgical correction. A rare, and therefore seldom, described cause of VPI is isolated unilateral agenesis of the soft palate. We describe the case of a 2-year-old patient with Stickler syndrome possessing a unique anatomic presentation of this pathology, managed successfully with a unilateral pharyngeal flap.

Abstract
Background Use of the Glatzel mirror for measuring expiratory nasal flow in preschool children has the disadvantage of vagueness, and the mirror may induce fear and inhibition of interest in those children. In response to these limitations, we developed a new device with dual cameras for measuring expiratory nasal flow in 2 to 6 year old children. The aim of this study is to compare the Glatzel mirror and the new device, in terms of accurate assessment of expiratory nasal flow, children's feelings, and correlation to each child's profile. Methods This study evaluated 20 cleft lip and palate patients and 21 healthy children aged between 2 and 6 (under 7) years. After consent was granted, a 4-week screening period was undertaken followed by inspection at weeks 8, 16, 24, and 32. Each inspection was conducted while the children were asked to pronounce various sounds and comprised three stages: i) use of the Glatzel mirror, ii) subjective visual assessment using the new device, and iii) image recording by dual cameras of the new device. Questionnaires for the new device were administered at the initial and final inspections. To contrast the results between the Glatzel mirror and the new device, the numbers that indicated values of subjective visual assessment and camera assessment greater than the assessment values of the Glatzel mirror were compared. For measuring the children's responses to the new device compared with those to the Glatzel mirror, the answers to the questionnaires were compared. For the comparison of the children's profiles (age and sex) and feelings, the numbers of subjects who could use the new device were measured. Results The camera assessment of the new device indicated significantly greater values than that of the Glatzel mirror (P < 0.05). The feelings of the subjects to the new device mostly improved as the study progressed. Subjects aged 3 years and older were generally able to use the new device from the initial inspection. For both sexes, as the inspection progressed, the number occasions of successful use increased. Conclusion This study demonstrated the superiority of the new device with dual cameras to the Glatzel mirror in terms of functionality and attitude of children.

Abstract
OBJECTIVES/HYPOTHESIS To investigate perceptual speech outcomes following sphincter pharyngoplasty (SP) and to identify patient characteristics associated with velopharyngeal insufficiency (VPI) resolution or improvement. METHODS Retrospective review of prospectively collected data was performed of consecutive patients that underwent SP for management of VPI between 1994 and 2016 at a single tertiary care pediatric hospital. Demographic data, nasendoscopic findings, and speech characteristics were recorded using a standardized protocol. Pre- and post-operative VPI was graded on a five-point Likert scale. Frequency of post-operative VPI resolution and improvement was assessed and associations with patient characteristics were analyzed. The association between odds of VPI resolution or improvement and five patient characteristics identified a priori was performed controlling for confounding factors. RESULTS Two-hundred ninety-six subjects were included. All patients had at least minimal VPI pre-operatively; 72% were graded moderate or severe. Sixty-four percent experienced resolution and 83% improved at least one point on the VPI-severity scale. Of the five patient characteristics, only history of cleft palate repair was significantly associated with decreased odds of VPI improvement but not resolution when controlling for other variables. CONCLUSIONS Sphincter pharyngoplasty resulted in resolution of VPI in 64% and improvement in 83% of subjects. Children with a history of cleft palate had significantly decreased odds of VPI improvement compared to those without a history of cleft palate. Neither syndrome diagnosis nor 22q11 deletion had a significant association with speech outcomes after sphincter pharyngoplasty. LEVEL OF EVIDENCE 4 Laryngoscope, 131:E2046-E2052, 2021.

Abstract
OBJECTIVES Prader-Willi syndrome (PWS) increases the risk of obstructive sleep apnea (OSA) due to obesity, hypotonia, and abnormal ventilatory responses. We evaluated post-adenotonsillectomy complications, polysomnography changes, and quality of life in children with OSA and PWS. STUDY DESIGN Systematic review and meta-analysis. METHODS We conducted a systematic review and meta-analysis by searching PubMed, Embase, Cochrane, Web of Science, and Scopus. Two researchers independently reviewed studies about adenotonsillectomy for OSA in patients <21 years with PWS. We extracted study design, patient numbers, age, complications, polysomnography, and quality of life. We pooled postoperative changes in apnea hypopnea index (AHI) for meta-analysis. We applied Methodological Index for Nonrandomized Studies (MINORS) criteria to assess study quality. RESULTS The initial search yielded 169 studies. We included 68 patients from eight studies with moderate to high risk of bias. Six studies reported on complications and 12 of 51 patients (24%) had at least one. Velopharyngeal insufficiency was the most commonly reported complication (7/51, 14%). We included seven studies in meta-analysis. Mean postoperative improvement in AHI was 7.7 (95% CI: 4.9-10.5). Postoperatively 20% (95% CI: 3%-43%) had resolution of OSA with AHI < 1.5 while 67% (95% CI: 50%-82%) had improvement from severe/moderate OSA to mild/resolved (AHI < 5). Two studies evaluated quality of life and demonstrated improvement. CONCLUSIONS Children with PWS undergoing adenotonsillectomy for OSA have a substantial risk of postoperative complications that may require additional interventions, especially velopharyngeal insufficiency. Despite improvements in polysomnography and quality of life, many patients had residual OSA. This information can be used to counsel families when considering OSA treatment options.

Abstract
OBJECTIVE To determine whether surgical intervention for submucous cleft palate (SMCP) is more common in children with 22q11.2 deletion syndrome (22q DS) compared to children without 22q DS. DESIGN Retrospective chart review. SETTING Tertiary pediatric hospital and 22q11.2 DS specialty clinic. PARTICIPANTS One hundred forty-two children seen at the tertiary hospital or clinic during a 20-year period (June 1999-June 2019) with documented SMCP with and without 22q DS. MAIN OUTCOME MEASURE Percentage of children with SMCP with and without 22q DS requiring surgical intervention for velopharyngeal insufficiency. RESULTS Patients with 22q DS had a significantly higher frequency of SMCP repair than those without 22q DS (89.7% vs 32.0%, P < .001, χ2 = 37.75). The odds of requiring SMCP repair were 18.6 times higher in those with 22q DS compared to those without (odds ratio = 18.6, CI = 6.1-56.6). CONCLUSIONS This study provides new evidence suggesting patients with 22q DS require SMCP surgical repair for velopharyngeal insufficiency at a significantly higher rate than those without 22q DS. As the majority of patients with 22q DS with SMCP require surgical intervention, future prospective studies looking at early versus late repair of SMCP in patients with 22q DS are needed to guide the surgical repair timeline in this population.

Abstract
Cleft palate repairs often require secondary surgeries and/or revisions for a variety of reasons. The most common causes are symptomatic oronasal fistulas and velopharyngeal insufficiency. Complications from primary surgery, such as wound dehiscence, infection, and hematomas, contribute to the relatively high rate of revision surgery. Prevention of postoperative complications that may lead to fistula or velopharyngeal insufficiency is key, and many techniques have been described that have reportedly decreased the incidence of secondary surgery. Management varies depending on the nature of the fistulous defect and the type of velopharyngeal insufficiency. Numerous surgical options exist to fix this deficiency.

Abstract
The posterior pharyngeal flap is frequently the surgical intervention of choice for the correction of velopharyngeal insufficiency. Our patient initially presented for a superiorly based, posterior pharyngeal flap to correct for velopharyngeal insufficiency. However, the postoperative recovery was complicated by severe obstructive sleep apnea, which warranted division and subsequent takedown of the flap. Despite flap takedown, our patient's obstructive sleep apnea persisted. The patient's clinical course suggests that donor site closure, and not the actual pharyngeal flap, caused the persistent obstructive sleep apnea.

Abstract
OBJECTIVE To evaluate the association of 2-stage cleft palate (CP) surgery on velopharyngeal insufficiency (VPI) incidence, speech surgeries, and cleft-related surgical burden. DESIGN Retrospective cohort with follow-up of 4 to 19 years. SETTING Academic, tertiary children's hospital. PATIENTS Patients who underwent CP surgery between 2000 and 2017. Exclusions included submucous CP or age at last contact under 3.9. INTERVENTIONS Cleft palate surgery, completed in either a single-stage or 2-stage repair. MAIN OUTCOME MEASURE(S) Rates of VPI diagnosis and speech surgery and total cleft surgeries; t tests, tests of proportion, and linear and logistic regression were performed. Total cleft-related surgeries were examined in a subset (n = 418) of patients with chart reviews. RESULTS A total of 1047 patients were included; 59.6% had 2-stage CP repair, 40.4% had single-stage repair. Approximately 32% of children with 2-stage CP repair were diagnosed with VPI, as opposed to 22% of single-stage patients (P < .001). Children with 2-stage CP repair were 1.8 times as likely to be diagnosed with VPI (P < .001). Speech surgery rates were similar across groups. Patients who had 2-stage repair received an average of 2.3 more cleft-related procedures, when excluding prosthesis management procedures. CONCLUSION Our data show an increased risk of VPI diagnosis and increased surgical burden among patients receiving 2-stage CP repair.

Abstract
BACKGROUND Palate re-repair has been proposed as an effective treatment for velopharyngeal insufficiency (VPI) with a low risk of obstructive sleep apnea (OSA). The authors conducted a systematic review and meta-analysis to determine the proportion of patients achieving normal speech resonance following palate re-repair for VPI, the proportion developing OSA, and the criteria for patient selection that are associated with increased effectiveness. METHODS PubMed, Embase, and Scopus were searched from inception through April 2018 for English language articles evaluating palate re-repair for the treatment of VPI in patients with a repaired cleft palate. Inclusion criteria included reporting of hypernasality, nasal air emission, nasometry, additional VPI surgery, and/or OSA outcomes. Meta-analysis was conducted using random effects models. Risk of bias was assessed regarding criteria for patient selection, blinding of outcome assessors, and validity of speech assessment scale. RESULTS Eighteen studies met inclusion criteria. The incidence of achieving no consistent hypernasality follow palate re-repair was 61% (95% confidence interval [CI]: 44%-75%). The incidence of additional surgery for persistent VPI symptoms was 21% (95% CI: 12%-33%). The incidence of OSA was 28% (95% CI: 13%-49%). Criteria for selecting patients to undergo re-repair varied, with anterior/sagittal position of palatal muscles (33%) and small velopharyngeal gap (22%) being the most common. No specific patient selection criteria led to superior speech outcomes (P = .6572). CONCLUSIONS Palate re-repair achieves normal speech resonance in many but not all patients with VPI. Further research is needed to identify the specific examination and imaging findings that predict successful correction of VPI with re-repair.

DESIGN Quality-of-life instrument translation and validation. SETTING Community served by Nepal's craniofacial referral hospital. PARTICIPANTS Twenty-three postpalatoplasty children with VPI, 19 family guardians of VPI cases, and 29 non-VPI controls. INTERVENTIONS The VELO instrument was translated to Nepali by 2 independent bilingual translators, reconciled, backward-translated, compared, and modified using patient cognitive interviews. All VPI children, guardians, and controls completed the VELO-Nepali. MAIN OUTCOME MEASURE(S) The VELO internal consistency was evaluated using Cronbach α coefficient. Concurrent validity and discriminant validity were assessed using 2-sample t test: assuming unequal variances. RESULTS The VELO was translated and optimized using cognitive interviews. The VELO-Nepali demonstrated excellent internal consistency, with Cronbach α coefficients of 0.93, 0.94, and 0.90 for VPI cases, guardians of VPI cases, and non-VPI controls, respectively. The VELO-Nepali exhibited strong discriminant validity between VPI cases (x¯ = 45.4, standard deviation [SD] = 22.1) and non-VPI controls (x¯ = 84.9, SD = 12.3), (P < .001). The VELO-Nepali showed strong concurrent validity with similarities in VPI case scores (x¯ = 45.4, SD = 22.1), and guardian scores (x¯ = 52.9, s = 22.8; P = .473). CONCLUSION The translated VELO-Nepali demonstrates strong internal consistency, discriminant validity, and concurrent validity, and can assess quality of life for Nepali VPI patients. This instrument represents the first VPI quality of life assessment validated in Nepali, and supports the feasibility of its implementation in other low- and low-middle-income countries.

Abstract
Autologous fat grafting has become a widely utilized technique for a variety of cosmetic and reconstructive procedures. Its potential for volume restoration and tissue regeneration has made it a popular method for treating soft tissue defects in both adult and pediatric populations. While autologous fat grafting in the pediatric setting is not as well characterized as it is in the adult setting, various reports have demonstrated the safety and utility of its applications in nonadult patient populations. In this article, we present the first comprehensive review of the current applications of autologous fat grafting in pediatric patients. Specific challenges to fat grafting in the pediatric setting and future applications will also be discussed.

Abstract
There are several different types of nasal emission that can occur during speech due to either velopharyngeal dysfunction or abnormal articulation in the pharynx. Nasal emission can be inaudible or very loud and distracting, depending on the size of the velopharyngeal opening and the physics of the flow. Nasal emission can be obligatory and/or compensatory (due to abnormal structure) or it can be caused by a misarticulation that results in a substitution of a pharyngeal sound for an oral sound, despite normal velopharyngeal structure. Nasal emission can occur on all pressure-sensitive phonemes or it can be phoneme-specific. Although it is generally recognized that the loud and distracting form of nasal emission (called nasal turbulence or nasal rustle) is due to a small velopharyngeal opening, the causality of the distracted sound is debated. This article provides a brief review of the types of nasal emission, the terms used to describe it, and the potential causes. This article also stresses the need for further research to clarify the causality of the sound generated by a small velopharyngeal opening.

Abstract
OBJECTIVE To explore the prognostic factors affecting the primary surgical management of aged patients with cleft palate. METHODS This study reviewed aged patients with cleft palate who received Furlow palatoplasty (surgical age≥5 years) at the cleft center at West China Hospital of Stomatology from 2009 to 2014. The study retrieved intraoperative mea-surements, including velar length, pharyngeal depth, cleft width, maxillary width, cleft palate index, and palatopharyngeal ratio. Speech evaluation results at follow-up at least a year after surgery were also obtained. Logistic regression and retrospec-tive analyses were performed to identify correlative prognostic factors. RESULTS One hundred and thirty-one patients were included (70 males and 61 females). Dichotomy logistic regression analysis revealed that pharyngeal depth was the only mea-surement considerably associated with postoperative velopharyngeal function. Pharyngeal depth deeper than 16 mm indicated high risk of postoperative velopharyngeal insufficiency. CONCLUSIONS Pharyn-geal depth is a significant prognostic factor for the primary surgical management of aged patients with cleft palate. Pharyn-goplasty might be considered when planning the primary management of aged patients.

Abstract
OBJECTIVE To determine whether orthodontic/dentofacial orthopedic maxillary protraction face mask therapy induces changes in velopharyngeal functioning in a cohort of pediatric patients having cleft palate with or without cleft lip. DESIGN Retrospective chart review. SETTING A children's hospital in the United States. PARTICIPANTS Forty-three pediatric patients with cleft palate, with or without cleft lip, syndromic or with isolated clefts, who received face mask therapy from January 2009 to April 2016. INTERVENTION Clinical data were extracted for review and analysis from medical records obtained from the Cleft Database/Research Registry (CDB-RR). MAIN OUTCOME MEASURES Pittsburgh Weighted Speech Scores (PWSS) before and after therapy. RESULTS There was a significant increase in PWSS after face mask therapy for patients with a PWSS score of 0 prior to treatment. Patients with PWSS >0 before treatment remained largely stable after face mask therapy. Maxillary advancement was not significantly associated with change in PWSS or fistula presence/absence. CONCLUSIONS There is an increased risk of velopharyngeal insufficiency with maxillary protraction face mask treatment in patients with cleft palate. Patient counseling and obtaining consent regarding speech changes during treatment are recommended.
