The impact of surgical technique and cleft width on the rate of secondary surgery and velopharyngeal function in children with UCLP at 5 years of age

Several factors may influence speech outcome and the rate of secondary palatal surgery in patients with cleft palate. The aim of this study was to evaluate different types of intra-velar veloplasty within an otherwise uniform surgical protocol. The impact of cleft width and the surgeon’s experience on outcome measurements was examined. This cross-sectional study included 62 individuals with unilateral cleft lip and palate born in 2000–2015. Based on the surgical technique used, they were divided into three groups. The cleft width was measured on dental casts. Blinded speech and language pathologists assessed velopharyngeal function with the composite score for velopharyngeal competence (VPC-Sum) for single words. They rated velopharyngeal function on a three-point scale (VPC-R) in sentences. Target consonants in words were phonetically transcribed. The percentage of correct consonants (PCC) was calculated. Surgical technique was not associated with any outcome. Cleft width was associated with the rate of secondary palatal surgery (OR 1.141, 95% CI 1.021–1.275, p = .020) and velopharyngeal insufficiency when using VPC-R (OR 2.700, 95% CI 1.053–6.919, p = .039) but not when using VPC-Sum (OR 1.985, 95% CI.845–4.662, p = .116). PCC was not associated with cleft width and did not differ between surgical techniques. Radical muscle dissection did not exhibit superiority over intra-velar veloplasty reinforced by the palatopharyngeal muscle. Follow-ups at later ages with larger groups will be necessary to evaluate and compare surgical techniques accurately. Cleft width had a greater impact on the rate of secondary surgery and velopharyngeal function than surgical technique, but neither affected the PCC.

A Comparative Effectiveness Study of Speech and Surgical Outcomes: Study Overview.

To provide an overview of the Cleft Outcomes Research NETwork (CORNET) and the CORNET Speech and Surgery study. The study is (1) comparing speech outcomes and fistula rate between two common palate repair techniques, straight-line closure with intra-velar veloplasty (IVVP) and Furlow Double-Opposing Z-palatoplasty (Furlow Z-plasty); (2) summarizing practice variation in the utilization of early intervention speech-language (EI-SL) services; and (3) exploring the association between EI-SL services and speech outcomes. Prospective, longitudinal, observational, comparative effectiveness, multi-center. Twenty sites across the United States. One thousand two hundred forty-seven children with cleft palate with or without cleft lip (CP ± L). Children with submucous cleft palate or bilateral sensorineural severe to profound hearing loss were excluded from participation. Straight-line closure with IVVP or Furlow Z-plasty based on each surgeon's standard clinical protocol. The primary study outcome is perceptual ratings of hypernasality judged from speech samples collected at 3 years of age. Secondary outcomes are fistula rate, measures of speech production, and quality of life. The statistical analyses will include generalized estimating equations with propensity score weighting to address potential confounders. Recruitment was completed in February 2023; 80% of children have been retained to date. Five hundred sixty two children have completed their final 3-year speech assessment. Final study activities will end in early 2025. This study addresses long-standing questions related to the effectiveness of the two most common palatoplasty approaches and describes CORNET which provides an infrastructure that will streamline future studies in all areas of cleft care.

Demystifying Velopharyngeal Dysfunction for Plastic Surgery Trainees Part 3: Objective Assessment and Surgical Decision-Making.

Velopharyngeal dysfunction (VPD) is the inability to achieve proper closure of the velopharyngeal (VP) port, affecting speech and swallowing. After an auditory-perceptual speech evaluation by a speech-language pathologist, objective assessment of the VP port is required to determine the need for surgical intervention. This 3-part series provides a comprehensive discussion on (1) the anatomy and physiology of the velopharyngeal mechanism; (2) fundamental speech terminology and principles of perceptual speech assessment for VPD; and (3) techniques for objective evaluation of the VP port and surgical decision-making process. In part 3, the authors focus on the modalities for objective VP port assessment, including both direct and indirect methods. Direct imaging techniques such as videofluoroscopy, nasoendoscopy, and MRI are detailed for their strengths and limitations in visualizing VP port function and preoperative planning. Indirect assessments, including nasometry and aerodynamic measurements, are also briefly discussed. The decision-making process for surgical intervention is explored, emphasizing factors such as the severity and etiology of VPD, VP closure patterns, palatal length, orientation of the levator veli palatini, and other patient-specific considerations. The authors review the surgical options for repair including palatoplasty procedures (Furlow palatoplasty, straight-line intravelar veloplasty, and palatal lengthening buccal myomucosal flaps) and pharyngoplasty procedures (posterior pharyngeal flaps and sphincter pharyngoplasty), highlighting their indications, techniques, and potential complications. This series serves as an accessible resource, providing the foundational knowledge required for surgical trainees new to this topic.

Demystifying the Suprazygomatic Maxillary Nerve Block in Paediatric Cleft Palate Surgery.

To consider the clinical anatomy, safety and effectiveness of the suprazygomatic maxillary nerve block in cleft palate surgery. Observational case series. Single cleft centre in the United Kingdom. Patients born with a cleft palate (with or without a cleft lip) undergoing palatal surgery between the ages of 9 months and 18 years. Introduction of suprazygomatic maxillary nerve (SZMN) block using ropivacaine 0.2% into clinical protocol in February 2023. Peri-procedure complications and post-operative opioid administration. The clinical anatomy of the SZMN block is described in a stepwise and pictorial approach from superficial to deep structures. 43 patients underwent surgical interventions involving the palate (either intravelar veloplasty, Furlow palatoplasty or bilateral myomucosal buccinator flaps for palatal lengthening). 22 patients had a general anaesthetic and local anaesthetic infiltration and 21 had an additional SZMN block. There were no local or systemic complications associated with the SZMN block. There was no difference in the total dosing of post-operative (P = .79) opioids between the groups. We demonstrate the feasibility and safety of this procedure without the use of ultrasound guidance in a heterogenous group of paediatric patients undergoing palatal surgery. Regional anaesthesia should be considered as part of the multi-modal analgesic strategy, although it may be difficult to demonstrate a change in opioid use in clinical settings where enhanced recovery techniques are established, and opioid use is already low.

Outcomes of Palatoplasty Techniques: A 10-Year Review of Intravelar Veloplasty Compared with Furlow Double-Opposing Z-Plasty Techniques

Outcomes of Palatoplasty Techniques: A 10-Year Review of Intravelar Veloplasty Compared with Furlow Double-Opposing Z-Plasty Techniques

Multicenter Pattern of Cleft Surgeries and Factors Associated with Late Primary Cleft Surgery in Nigeria.

This study aimed to analyze multicenter patterns in cleft deformity surgeries and identify factors associated with the timing of primary cleft repair in Nigeria. A cross-sectional study of children managed for clefts from January 2009 to December 2020 at three Smile Train partner tertiary institutions situated in the east (Enugu), west (Ibadan), and northern (Jos) parts of the country using a prospectively collected database. Outcomes were the types of surgery performed, yearly volume of surgeries, methods of repair, and time of surgery (early versus late). Of 1043 cleft surgeries, nearly half (45.7%) involved infants (<12 months). Primary repairs of the lip or palate were performed in 83.4% of cases, with 58.4% for lip repairs and 25.1% for palate repairs. The most common cleft lip repair method was a variant of Millard rotation advancement flap. Over the study years, there was a shift from von Langenbeck palatoplasty to methods such as Bardach's palatoplasty and intravelar veloplasty. Patients with bilateral cleft lip defects were significantly more likely (P < 0.001) to undergo early repairs compared with those with unilateral defects. Late primary cleft lip repairs were significantly (P < 0.001) more common in Enugu. This study highlights the variability in cleft surgery patterns in Nigeria. Late primary cleft surgeries were associated with less severe cleft lip or cleft palate and were more prevalent in Enugu, Southeastern Nigeria. The findings contribute valuable insights for optimizing surgical approaches and resource allocation in the management of cleft deformities in the region.

The influence of three different primary treatment protocols on 5-year-old maxillary growth in patients with complete unilateral cleft lip and palate

The study evaluated the effects of three different primary treatment protocols on maxillary growth in patients aged 5 years with complete unilateral cleft lip and palate (UCLP). The secondary objective was to assess the influence of initial cleft severity, family history of class III, and status of permanent lateral incisor on maxillary growth.In total, 54 patients with non-syndromic complete UCLP were included and grouped as follows: group An underwent lip adhesion, cheilorhinoplasty associated with tibial periosteal graft for hard palate repair, and finally veloplasty; group B underwent lip adhesion, then cheilorhinoplasty with intravelar veloplasty, and finally a hard-palate repair; group C underwent cheilorhinoplasty with intravelar veloplasty and then a hard-palate repair. Five-year maxillary growth was assessed on dental models, both clinically and digitally.No difference was found with GOSLON-Yardstick scoring. Five-year measurements showed that group C tended to have the best maxillary arch morphology (p = 0.012). Initial cleft severity did not impact maxillary growth, but status of permanent lateral incisor and family history of class III did (p = 0.019 and p = 0.004, respectively).In patients aged 5 years, the two-stage approach appeared to be the least detrimental to growth development. Predictive factors for growth retardation included the absence of lateral incisor and a family history of class III.

Outcomes of primary repair of cleft palate using sommerled intravelar veloplasty associated with velocardiofacial syndrome

ObjectivesVelocardiofacial syndrome, a prevalent microdeletion syndrome occurring in 1 in 2000–4000 live births, is marked by speech and language disorders, notably velopharyngeal dysfunction. This study investigates speech outcomes, nasometric and videofluoroscopic results before and after primary repair of cleft palate using the Sommerlad intravelar veloplasty (SIVV) technique within the Isfahan cleft care team for patients with velocardiofacial syndrome. MethodsEmploying a quasi-experimental design, 19 participants with velocardiofacial syndrome, who underwent primary cleft palate repair by the Isfahan cleft care team, were included through convenience sampling. Perceptual and instrumental outcomes were assessed pre-and post-operatively. Statistical analysis encompassed paired t-tests and the non-parametric Wilcoxon signed-rank test (p < 0.05). ResultsThe study identified no statistically significant differences between pre-and post-surgical speech outcome parameters and nasalance scores. Nonetheless, a significant distinction emerged in the velopharyngeal closure ratio based on fluoroscopic evaluation (p = 0.038). ConclusionThe efficacy of the SIVV technique in treating velopharyngeal dysfunction in velocardiofacial syndrome patients is inconclusive, demanding further research. Post-surgical speech outcomes are influenced by surgical technique, hypotonia, apraxia of speech, and surgery timing. Notably, an elevated velopharyngeal valve closure ratio, though anatomically indicative, does not exclusively predict surgical success.

Клінічний випадок пізньої корекції щілини твердого піднебіння в 11-річного хлопця з двобічною розщілиною губи і піднебіння

Clefts of the lip and palate remain one of the most common congenital malformations. Bilateral cleft is considered the most complex form of the defect. There is no consensus on the timing and method of surgical treatment. However, most publications focus on the two-stage method of defect closure and recommend complete correction by 24 months of age. This clinical case deviates from the commonly accepted approach to treating children with bilateral clefts of the lip and palate. The patient sought medical help at a late age, specifically at 11 years old, due to a number of subjective and objective reasons. The aim - based on a clinical case, analyze the timely and qualitative provision of medical care, the difference in the quality of life before and after surgical intervention in patients with the described pathology. The first stage was performed at the age of 2 years. After preoperative preparation, including antibiotic therapy guided by throat swabs, the patient underwent a series of surgical procedures, including complete dissection of soft palate muscles, intravelar veloplasty, formation of a Vomer flap, and meticulous closure of the palate defect layer by layer. One month after the surgery, the patient exhibited soft palate movements (which were absent before surgery), improved feeding, and continued speech therapy sessions, resulting in significantly improved pronunciation. Analysis of this clinical case will contribute to a better understanding of the approach to treating children with bilateral clefts of the lip and palate. Timely referral of patients for comprehensive treatment, including surgical correction, subsequent orthodontic treatment, speech therapy sessions, possible psychological rehabilitation, and so on, is crucial in children with bilateral clefts of the lip and palate. The research was carried out in accordance with the principles of the Helsinki Declaration. The informed consent of the patient was obtained for conducting the studies. No conflict of interests was declared by the authors.

The relationship between cleft palate repair technique and audiological outcomes: A retrospective cohort study.

Otitis media with effusion is common in children with cleft palates. This study aimed to investigate the link between palatal closure techniques and audiological outcomes. In this retrospective-prospective cohort study, we examined the relationship between palate repair techniques and hearing outcomes in children with cleft palates. From 2017 to 2022, 190 ears of 95 cleft patients were studied at the Cleft Lip and Palate Department of Shiraz University of Medical Sciences. Variables assessed included the surgical technique, cleft severity, auditory brainstem response (ABR) threshold, and tympanometry configuration. The mean ABR improved from a prepalatoplasty value of 39.51(11.62) decibels (dB) to a postpalatoplasty mean of 26.61(11.60) dB (Cohen's d: 1.12 [95% CI; 0.90-1.34]). Initially, 87.9% of the studied ears exhibited abnormal tympanometry, but this significantly decreased to 47% postsurgery (risk ratio: 4.43 [95% CI; 1.20-16.43]). When compared with Sommerlad intravelar veloplasty, the Nadjmi modified Furlow palatoplasty was associated with a notably lower mean ABR (β: -6.58 [95% CI: -10.43 to -2.73], p-value = .001) and a reduced frequency of abnormal tympanometry (odds ratio [OR]: -1.10; 95% CI: -1.85 to -0.36, p-value = .004). Factors like prepalatoplasty ABR, cleft palate severity, gender, and syndromic did not confound these findings. Although the Nadjmi modified Furlow palatoplasty showed better results, our findings indicate a significant improvement in ABR and tympanometry outcomes for both techniques. Future randomized controlled trials are suggested to confirm the influence of palatal closure techniques on audiological outcomes. 3b.

Comparison of Furlow's Double Opposing Z-plasty and Straight-Line Intravelar Veloplasty as Methods of Cleft Palate Repair.

Background One of the common craniofacial abnormalities is cleft lip and palate. Various surgical procedures have been employed to repair the cleft. However, immediate post-operative complications and formation of palatal fistula post surgery are common in surgical procedures. The study aims to compare the fistula rate, soft palate lengthening, and immediate complications of cleft palate repair of Furlow's Z-plasty and straight-line intravelar veloplasty techniques. Method Fifty Patients with isolated or unilateral cleft palate and lip with age between 9-18 months were randomly divided into two groups. One group underwent Furlow's Z-plasty while the other underwent straight-line intravelar veloplasty procedures. Post surgery, after discharge, the patients were followed up at 2 weeks, 1 month, and 3 months intervals. Immediate post-operative complications and fistula formation rate were compared along with other parameters like fistula width, duration of the procedure, intra-operative soft palate length, etc. Results Straight-line procedures took less time as compared to Furlow's Z-plasty. Bleeding (N=2, 8%) and dehiscence (N=1, 4%) of the woundwere the immediate post-operative complications found in the straight-line group. Bleeding was also presentin the Furlow's group (N=1, 4%). At 1-month follow-up, in the straight-line group (N=3, 12%) patients had fistula while(N=2, 8%) had minimal nasal regurgitation of liquids when compared to the Furlow's group. At 3-month follow-up, patients in the straight-line proceduregroup (three out of N=25, 12%) exhibited fistula, whereas in the Furlow's group, fistula occurrence was observed in one out of N=25 participants (4%). Intra-operative soft palate lengthening was 6.44 ± 0.768 mm and 1.64 ± 0.952 mm in the Furlow and straight-line groups, respectively. Conclusion Furlow's Z-plasty was observed to be the better surgical procedure for cleft repair as it had low immediate post-operative complications, and fistula development and had higher intra-operative soft palate lengthening.

Experience with double transposition flaps and intravelar veloplasty for closure of wide cleft palates

ABSTRACT Background: Repairing a wide cleft palate is a challenging task for surgeons. The goals of cleft palate repair such as achieving anatomical closure of the defect, complete velopharyngeal closure, speech development, and to minimize dentoalveolar anomalies are difficult to achieve in wide and massive cleft palates. Several methods have been described for the same. We performed double transposition flaps combined with intravelar veloplasty in our patients. In this article, we share our experience with the same. Materials and Methods: We reviewed 9 cases, in which double transposition flaps with intravelar veloplasty were performed. Patient demographics, clinical data, and outcomes were analyzed. Functional status including nasal resonance and palatal mobility were assessed with nasal endoscopy. Results: The average age at the time of surgery was 17 months. Four patients had associated diseases. The mean operative time was 55.7 min. The mean follow-up period is 23.7 months. Only posterior palatal closure was done in all the cases and patients were managed temporarily with obturators and are planned for delayed closure later. Conclusion: Double transposition flap is a safe, effective, and technically less demanding procedure. It has no wound complications and can avoid the need for osteotomy to correct maxillary retrusion. The main drawback of the procedure is the creation of an anterior palatal fistula that needs closure later.

Velopharyngeal Insufficiency Following Furlow Versus Straight Line Repair With Intravelar Veloplasty: A Single-institution Experience

Background: Measurements of postoperative velopharyngeal dysfunction (VPD) can be used to determine the efficacy of a palatoplasty operation. Hypernasality and audible nasal air emission are typical manifestations of VPD during speech. We aimed to longitudinally compare VPD outcomes in postpalatoplasty patients who underwent Furlow repair versus straight line repair with intravelar veloplasty (IVVP). Additionally, we examined the relationship between VPD outcomes and select pre-existing patient characteristics. Methods: Retrospective chart review was performed to identify primary palatoplasty patients treated from April 2012 to March 2021. Variables collected included gender, syndromic status, primary language, Veau cleft type, type of speech assessment, age at time of surgery, degree of hypernasality, presence of audible nasal air emission, and overall adequacy of velopharyngeal function. Pearson χ2 test and multivariable t tests were used to analyze variables. Logistic regression was used to control for statistically significant variables. Results: Of the 118 patients included, 38 received a Furlow procedure and 80 received a straight line with IVVP procedure. Audible nasal air emission was present in 57.3% of straight line with IVVP patients and 42.9% of Furlow patients, with no statistically significant difference between groups. Clinically significant hypernasality was present in 42.1% of straight line with IVVP patients and 22.9% of Furlow patients (P=0.05). Velopharyngeal function was classified as adequate in 63.5% of straight line with IVVP patients and 83.3% of Furlow patients (P=0.03). However, after stratifying by syndromic versus nonsyndromic status, there was no statistically significant difference between straight line with IVVP and Furlow patients for postoperative hypernasality and velopharyngeal function. Conclusions: This study suggests that there are no statistically significant differences between straight line with IVVP and Furlow palatoplasty techniques regarding speech outcomes including hypernasality, audible nasal air emission, and overall VP function. Furthermore, select patient characteristics such as gender, primary language, syndromic status, age at repair, and Veau cleft type do not significantly impact postoperative speech outcomes.

Comparative quantitative analysis of intravelar veloplasty and Furlow double opposing z plasty techniques for transposition of LVP muscles to correct VPI

Purpose The present study was performed to use quantitative analysis of LVP by magnetic resonance imaging (MRI) to compare intravelar veloplasty versus Furlow double opposing z-plasty technique in VPI correction. Materials and methods This is an interventional, comparative study that was carried out on 16 patients with velopharyngeal insufficiency due to decreased velar mobility divided into two equal groups, group I: included eight patients in whom VPI was repaired with intravelar veloplasty, group II: included eight patients in whom VPI was repaired with Furlow double opposing z-plasty. All patients underwent regular follow-up for 3 months by clinical, nasopharyngoscopy and MRI. Results Clinically, there was primary wound healing uneventfully was achieved in all patients in the two groups with no signs of infection. By MRI there was a significant increase in the angle of origin, length and thickness of the LVP postoperatively in both groups with no significant differences between them which confirmed with increased velum mobility postoperatively in both groups in nasopharyngoscopy. Conclusion According to quantitative analysis of LVP by MRI preoperatively and postoperatively, there was no statistically significant differences between intravelar veloplasty and Furlow double opposing z-plasty technique in VPI correction.

Speech Outcomes and Velopharyngeal Function in Children Undergoing Submucous Cleft Palate Repair.

Describe and compare the results of speech and velopharyngeal function in children with classic and occult submucous cleft palate undergoing interdisciplinary treatment at the Gantz Foundation. The clinical history of all patients born between 2012 and 2017 with a diagnosis of classic or occult submucous cleft palate was retrospectively reviewed. Preoperative and postoperative medical, surgical, and speech and language history were collected. Twenty-eight cases diagnosed at the age of 44.8±23.9 months were included. Of these, 71.4% presented classic submucous cleft, and 28.6% occult. Before primary surgery, 7.1% had a diagnosis of the syndrome, and 21.4% were under study. A total of 39.3% had hearing difficulties and 21.4% used tympanic ventilation tubes. A total of 60.7% had language problems, 39.3% had compensatory articulation, 17.9% had absent hypernasality, and 21.4% had absent nasal emission. The team indicated primary palate surgery in 71.4%, of which 85% performed the surgery at the mean age of 61.7±24.7 months. The surgical technique was Furlow in 88.2% of the cases and intravelar veloplasty in the remaining 11.8%. Then, 3 cases underwent velopharyngeal insufficiency surgery; 2 of them eliminated hypernasality and reduced nasal emission. The age of diagnosis ( P =0.021) and the performance of velopharyngeal insufficiency surgery ( P =0029) of the occult submucous cleft palate group was significatively later than the classic cleft palate group. Language, hearing, compensatory articulation, hypernasality, and nasal emission problems were recorded. A high percentage required primary surgery. Of these, a low proportion also required a velopharyngeal insufficiency surgery, which improved the velopharyngeal function of the children but did not completely adapt it. In this regard, early diagnosis is essential, as well as an analysis of each center primary closure protocol.

Surgery for Velopharyngeal Insufficiency Following Cleft Palate Repair: An Audit of Contemporary Practice and Proposed Schema of Techniques and Variations.

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. 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. 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.

Single Oral Z-Plasty: A Clinical Validation of a Technique for Palatal Lengthening in Primary and Secondary Cleft Palate Repair.

In cleft palate repair, palate length is associated with improved speech outcomes. Although direct closure offers poor palatal lengthening, use of two opposing Z-plasties may reorient palatal musculature and lengthen the velum. The authors previously described a novel overlapping intravelar veloplasty to achieve longitudinal closure of the nasal mucosa with a single oral Z-plasty (1ZP), lengthening the palate in cadaver studies. This study aims to corroborate this finding in clinical cases. A retrospective comparative study of patients with a cleft palate was conducted. Patients underwent cleft palate closure with 1ZP or intravelar veloplasty with straight-line closure. Preoperative and postoperative measurements of the palate along four dimensions were recorded. Analysis was conducted on preoperative and postoperative measurements within and between groups using the Mann-Whitney-Wilcoxon or chi-square test. Eighty-five patients were included (1ZP, n = 65; straight-line closure, n = 20). 1ZP increased soft palate length (SPL) by 33% ( P < 0.001) and total palate length (TPL) by 10% ( P < 0.001). Primary 1ZP increased SPL by 33% ( P < 0.001) and TPL by 10% ( P < 0.001). Secondary 1ZP increased SPL by 28% ( P < 0.001) and TPL by 8% ( P < 0.001). When comparing between primary and secondary 1ZP, 1ZP was equal with regard to percentage lengthening in SPL ( P > 0.9) and TPL ( P > 0.3). When compared with straight-line closure, 1ZP showed superior percentage lengthening in SPL ( P < 0.001) and TPL ( P = 0.038). 1ZP results in a statistically significant increase in palate length in both primary and secondary cleft palate repair. This technique provides an effective alternative in patients for whom 2ZP is not feasible. Therapeutic, III.

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

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

Hybrid Palatoplasty: A Simplified DOZ (Double Opposing Z Plasty) with Palatal Myoplasty for Primary Palate Repair.

Introduction Surgical techniques for soft palate repair aiming for zero velopharyngeal insufficiency (VPI) are still not achieved. Straight line closure of the soft palate by various techniques of intravelar veloplasty (IVVP) leads to higher incidence of VPI due to scar contracture. Furlow's Z plasty has long, narrow, thin mucosal flaps and mucomuscular flaps with malaligned muscle closure. We present a technique of "hybrid palatoplasty" which borrows from and adds to the existing methods, is robust, is easy to replicate, and results in normal speech consistently. Aim (1) To design a technique of "hybrid palatoplasty"-combining double opposing Z (DOZ) plasty and IVVP, which is applicable to all types of cleft palate. (2) To evaluate the results of cleft palate children operated using the technique of "hybrid palatoplasty" from 2014 to 2015 in terms of surgical complications (fistulae and dehiscence) and incidence of VPI. Methods Our procedure combines aspects of both DOZ and IVVP. It is simplified with design of smaller Z plasties. On one side, from the oral Z plasty muscle is dissected off and sutured to the nasal mucomuscular flap of the opposite side to complete the palatal sling. Oral Z plasty is purely mucosal and reverse of the nasal side. A total of 123 cases, operated below 5 years of age were followed up. Speech was assessed by direct evaluation and tele-evaluation. Results A total of 123 cases, below 5 years of age, were operated between 2014 and 2016 with at least 5 years of follow-up. Note that 120 had normal speech, and 3 had VPI of which 2 were subsequently corrected and went on to develop normal speech. Conclusion This novel "hybrid palatoplasty" is a simple technique with good speech outcome as it combines the principles of Z plasty and direct muscle repair with palatal sling formation.
