Three-dimensional finite element analysis on stress distribution after different palatoplasty and levator veli palatini muscle reconstruction. Clin Oral Investig 2024; 28:221. [PMID: 38499908 DOI: 10.1007/s00784-024-05583-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2023] [Accepted: 02/25/2024] [Indexed: 03/20/2024]
Abstract
OBJECTIVES To establish a three-dimensional finite element model of the upper palate, pharyngeal cavity, and levator veli palatini muscle in patients with unilateral complete cleft palate, simulate two surgical procedures that the two-flap method and Furlow reverse double Z method, observe the stress distribution of the upper palate soft tissue and changes in pharyngeal cavity area after different surgical methods, and verify the accuracy of the model by reconstructing and measuring the levator veli palatini muscle. MATERIALS AND METHODS Mimics, Geomagic, Ansys, and Hypermesh were applied to establish three-dimensional finite element models of the pharyngeal cavity, upper palate, and levator veli palatini muscle in patients with unilateral complete cleft palate. The parameters including length, angle, and cross-sectional area of the levator veli palatini muscle etc. were measured in Mimics, and two surgical procedures that two-flap method and Furlow reverse double Z method were simulated in Ansys, and the area of pharyngeal cavity was measured by hypermesh. RESULTS A three-dimensional finite element model of the upper palate, pharyngeal cavity, and bilateral levator veli palatini muscle was established in patients with unilateral complete cleft palate ; The concept of horizontal projection characteristics of the palatal dome was applied to the finite element simulation of cleft palate surgery, vividly simulating the displacement and elastic stretching of the two flap method and Furlow reverse double Z method during the surgical process; The areas with the highest stress in the two-flap method and Furlow reverse double Z method both occur in the hard soft palate junction area; In resting state, as measured, the two flap method can narrow the pharyngeal cavity area by 50.9%, while the Furlow reverse double Z method can narrow the pharyngeal cavity area by 65.4%; The measurement results of the levator veli palatini muscle showed no significant difference compared to previous studies, confirming the accuracy of the model. CONCLUSIONS The finite element method was used to establish a model to simulate the surgical procedure, which is effective and reliable. The area with the highest postoperative stress for both methods is the hard soft palate junction area, and the stress of the Furlow reverse double Z method is lower than that of the two-flap method. The anatomical conditions of pharyngeal cavity of Furlow reverse double Z method are better than that of two-flap method in the resting state. CLINICAL RELEVANCE This article uses three-dimensional finite element method to simulate the commonly used two-flap method and Furlow reverse double Z method in clinical cleft palate surgery, and analyzes the stress distribution characteristics and changes in pharyngeal cavity area of the two surgical methods, in order to provide a theoretical basis for the surgeon to choose the surgical method and reduce the occurrence of complications.

J Plast Reconstr Aesthet Surg 2024; 90:240-248.

Abstract
INTRODUCTION Speech in children with cleft palate can be affected by velopharyngeal dysfunction, which persists after primary palate repair. The incidence of surgery to correct velopharyngeal dysfunction in this patient group has previously been reported as 2.6-37%. We aimed to investigate the incidence of velopharyngeal dysfunction surgery in Swedish children with cleft palate and to examine potential associations of independent variables with this incidence. METHODS In this cohort study, we analysed data from the Swedish cleft lip and palate quality registry for 1093 children with cleft palate with or without cleft lip. Kaplan-Meier analysis was used to estimate the risk of having velopharyngeal dysfunction surgery. Multivariable Cox proportional hazards models were used to estimate the associated effect of cleft subtype, additional diagnoses, gender, and age at and number of stages for primary palate repair on the primary outcome. RESULTS The risk of having velopharyngeal dysfunction surgery was 25.6%. Complete primary palate repair after the age of 18 months or in more than one stage was associated with a higher risk, but it could not be determined which of these was the more significant factor. Cleft soft palate was associated with a significantly lower risk than other cleft subtypes. CONCLUSIONS Primary palate repair at a higher age or in more than one stage may increase the risk of having velopharyngeal dysfunction surgery. Further analysis of potential unknown confounding factors and the association between the incidence of velopharyngeal dysfunction and surgery to correct this condition is needed.

Proposed clinical model for predicting speech outcomes in patients undergoing Furlow palatoplasty for velopharyngeal insufficiency after primary palatoplasty. J Craniomaxillofac Surg 2024; 52:234-239. [PMID: 38161074 DOI: 10.1016/j.jcms.2023.12.007] [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: 05/18/2022] [Revised: 11/23/2023] [Accepted: 12/12/2023] [Indexed: 01/03/2024] Open
Abstract
This study aimed to validate the predictors of speech outcomes following Furlow palatoplasty in patients with velopharyngeal insufficiency (VPI) after primary palatoplasty and to propose and validate a model to predict the risk of persistent VPI. The study included patients with VPI after primary palatoplasty who underwent Furlow palatoplasty as a secondary surgery. Eleven variables were included: velar length, pharyngeal cavity depth, velopharyngeal gap, velopharyngeal closure pattern, sex, presence of cleft lip, existence of palatal fistula, surgeon, age at primary palatoplasty, age at secondary surgery, and time interval between primary palatoplasty and secondary surgery. Postoperative speech outcomes were assessed at least 1 year after the secondary surgery and classified as velopharyngeal competence (VPC) or VPI. Variables were analyzed using multivariate logistic regression analysis, and the area under the curve (AUC) was used to validate model accuracy. The study sample comprised 101 patients. Of the patients, 62 had VPC and 39 had VPI after secondary surgery. The results showed a younger age at secondary surgery, a smaller velopharyngeal gap, being female, having a coronal velopharyngeal closure pattern and a velopharyngeal closure ratio of 90% or greater produced a greater probability of VPC. Given the constraints of this study, it appears that the Furlow palatoplasty should be prioritized when the clinical model predicts a substantial likelihood of VPC post-surgery.

Abstract
To investigate the relationship between patient-related factors (sex, cleft type, cleft extent, and Robin Sequence [RS]) and speech outcome at 5 years of age for children born with a cleft palate ± lip (CP ± L). 3157 Children (1426 female:1731 male) with a nonsyndromic CP ± L, born between 2006 and 2014 in England, Wales, and Northern Ireland. Perceptual speech analysis utilized the Cleft Audit Protocol for Speech-Augmented (CAPS-A) rating and UK National Speech Outcome Standards: Speech Standard 1 (SS1)-speech within the normal range, SS2a-no structurally related speech difficulties or history of speech surgery, and SS3-speech without significant cleft-related articulation difficulties. Odds of achieving SS1 were lower among boys (aOR 0.771 [CI 0.660-0.901]), those with clefts involving the lip and palate (vs palate only) (UCLP-aOR 0.719 [CI 0.591-0.875]; BCLP-aOR 0.360 [CI 0.279-0.463]), and clefts involving the hard palate (incomplete-aOR 0.701 [CI 0.540-0.909]; complete-aOR 0.393 [CI 0.308-0.501]). Similar relationships with these patient factors were observed for SS3. SS2 was affected by the extent of hard palate involvement (complete; aOR 0.449 [CI 0.348-0.580]). Although those with CP and RS were less likely to meet all 3 standards than those without RS, odds ratios were not significant when adjusting for sex and cleft extent. Sex, cleft type, and extent of hard palate involvement have a significant impact on speech outcome at 5 years of age. Incorporating these factors into risk-adjustment models for service-level outcome reporting is recommended.

Abstract
OBJECTIVE To assess the ability of a cleft-specific multi-site learning health network registry to describe variations in cleft outcomes by cleft phenotypes, ages, and treatment centers. Observed variations were assessed for coherence with prior study findings. DESIGN Cross-sectional analysis of prospectively collected data from 2019-2022. SETTING Six cleft treatment centers collected data systematically during routine clinic appointments according to a standardized protocol. PARTICIPANTS 714 English-speaking children and adolescents with non-syndromic cleft lip/palate. INTERVENTION Routine multidisciplinary care and systematic outcomes measurement by cleft teams. OUTCOME MEASURES Speech outcomes included articulatory accuracy measured by Percent Consonants Correct (PCC), velopharyngeal function measured by Velopharyngeal Competence (VPC) Rating Scale (VPC-R), intelligibility measured by caregiver-reported Intelligibility in Context Scale (ICS), and two CLEFT-Q™ surveys, in which patients rate their own speech function and level of speech distress. RESULTS 12year-olds exhibited high median PCC scores (91-100%), high frequency of velopharyngeal competency (62.50-100%), and high median Speech Function (80-91) relative to younger peers parsed by phenotype. Patients with bilateral cleft lip, alveolus, and palate reported low PCC scores (51-91%) relative to peers at some ages and low frequency of velopharyngeal competency (26.67%) at 5 years. ICS scores ranged from 3.93-5.0 for all ages and phenotypes. Speech Function and Speech Distress were similar across phenotypes. CONCLUSIONS This exploration of speech outcomes demonstrates the current ability of the cleft-specific registry to support cleft research efforts as a source of "real-world" data. Further work is focused on developing robust methodology for hypothesis-driven research and causal inference.

Abstract
While bilateral cleft lip and palate (BCLP) constitutes a clinical challenge for the whole cleft team, the ideal surgical protocol remains obscure. This study presents the long-term burden of care in terms of secondary surgeries, defined as fistula repair and speech-correcting surgeries (SCS), in a single center. Outcomes of two surgical protocols utilized over the years were also compared. A retrospective single-center analysis of 81 non-syndromic children with complete BCLP born between 1990 and 2010. Two surgical protocols comprising single-stage and two-stage (delayed hard palate closure) procedures were compared. Outcome was analyzed at the time of alveolar bone grafting (ABG) and post-ABG. Altogether 54 children (66.7%) had underwent secondary surgery by the time of bilateral ABG. At this point, 38.3% (n = 31) of patients had received SCS and 49.4% (n = 40) had undergone fistula repair. The corresponding incidences at the end of follow-up were 46.9% (n = 38) and 53.1% (n = 43). No significant difference emerged in SCS incidence between the 2 protocols; however, prior to ABG the single-stage protocol had a significantly lower need for fistula repair. Regarding the location of fistulas, some differences were observed, with the single-stage procedure more associated with anterior fistulas. BCLP has a high surgical burden of care in terms of secondary surgeries, defined as SCS and fistula repair. In our experience, the single-stage protocol, particularly the two-flap technique, offers better results in the management of BCLP than the two-stage approach with a short delay in hard palate closure.

Fat grafting in patients with cleft lip and palate: A systematic review. J Craniomaxillofac Surg 2023; 51:178-187.

Abstract
This systematic review aims to compare different fat-grafting techniques for cleft lip and palate repair. A search was conducted in PubMed, Embase, Cochrane Library, gray literature and reference lists of selected articles. A total of 25 articles were included, 12 on closure of palatal fistula and 13 on cleft lip repair. The rate of complete resolution of palatal fistula ranged from 88.6% to 100% in studies with no control group, whereas in comparative studies patients receiving a fat graft showed better outcomes than those not receiving a graft. Evidence suggests that fat grafting can be indicated for the primary and secondary repair of cleft palate, with good results. The use of dermis-fat grafts in lip repair was associated with gains in surface area (11.5%), vertical height (18.5%-27.11%), and lip projection (20%). Fat infiltration was associated with increased lip volume (6.5%), vermilion show (31.68% ± 24.03%), and lip projection (46.71% ± 31.3%). The available literature suggests that fat grafting is a promising autogenous option for palate and fistula repair and for improvement of lip projection and scar aesthetics in patients with cleft. However, to develop a guideline, further studies are needed to confirm whether one technique is superior to the other.

Obturator Manufacturing for Oronasal Fistula after Cleft Palate Repair: A Review from Handicraft to the Application of Digital Techniques. J Funct Biomater 2022; 13:jfb13040251.

Abstract
An oronasal fistula (ONF) is an abnormal structure between the oral and nasal cavities, which is a common complication of cleft palate repair due to the failure of wound healing. When some patients with ONF are unsuitable for secondary surgical repair, the obturator treatment becomes a potential method. The objectives of the obturator treatment should be summarized as filling the ONF comfortably and cosmetically restoring the dentition with partial function. The anatomy of patients with cleft palate is complex, which may lead to a more complex structure of the ONF. Thus, the manufacturing process of the obturator for these patients is more difficult. For performing the design and fabrication process rapidly and precisely, digital techniques can help, but limitations still exist. In this review, literature searches were conducted through Medline via PubMed, Wiley Online Library, Science Direct, and Web of Science, and 122 articles were selected. The purpose of this review was to introduce the development of the obturator for treating patients with ONF after cleft palate repair, from the initial achievement of the obstruction of the ONF to later problems such as fixation, velopharyngeal insufficiency, and infection, as well as the application of digital technologies in obturator manufacturing.

Abstract
The oral and maxillofacial region contains oral organs and facial soft tissues. Due to the complexity of the structures and functions of this region, the repair of related defects is complicated. Different degrees of defects require different repair methods, which involve a great combination of medicine and art, and the material requirements are extremely high. Hence, clinicians are plagued by contemporary oral repair materials due to the limitations of bone harvesting, immune rejection, low osteogenic activity and other problems. Decellularized extracellular matrix has attracted much attention as a bioactive scaffold material because of its nonimmunogenic properties, good osteogenic properties, slow release of growth factors, promotion of seed cell adhesion and maintenance of stem cell characteristics. This article reviews the sources, preparation methods, application and research progress of extracellular matrix materials in the repair of oral and maxillofacial defects to provide an overview for fundamental research and clinical development.

Palatoplasty Using Alveolar Ridge Incisions: A Novel Approach for Addressing Cleft Palate Deformities. Plast Reconstr Surg Glob Open 2022; 10:e4275. [PMID: 35450267 PMCID: PMC9015198 DOI: 10.1097/gox.0000000000004275] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2022] [Accepted: 02/24/2022] [Indexed: 11/26/2022]
Abstract
Background: Traditionally, plastic surgeons have performed palatoplasties using mucoperiosteal flaps with lateral incisions that are medial to the alveolar ridge. However, narrow flaps can cause limitations in some cases. To construct larger and wider flaps and minimize exposed bone after closure, we propose a novel technique that entails creating the lateral incisions at the top of the alveolar ridge, instead of the base of the alveolar ridge, to capture more tissue when repairing the hard palate. Methods: A retrospective chart review was conducted for patients undergoing cleft palate repair with the aforementioned technique. Information collected included basic demographic and diagnostic factors related to cleft palate deformity and history of previous facial surgeries. Operative report details and postoperative complications were analyzed. Results: Nineteen patients with hard palate clefts were included in the analysis, with the majority being women (68%). There was a balanced representation of patients with Veau classifications of II (47%) and III (42%). The majority of patients had an isolated cleft palate (74%) and incomplete deformity (63%), with no other craniofacial deformities. One (5%) had postoperative self-limited oronasal fistula managed conservatively. Conclusions: We present a novel approach for repairing cleft palate deformities by extending the lateral incision to the top of the alveolar ridge to create larger mucosal flaps. Further longitudinal studies are needed to evaluate how this unique approach compares to traditional methods—with respect to impact on maxillary growth processes, requirement for subsequent surgeries beyond two years of follow-up, and ultimately normalized speech over time.

Comparison of recurrence rate and speech outcome between two different techniques for cleft palatal fistula closure: A retrospective cohort study. J Craniomaxillofac Surg 2021; 50:86-92. [PMID: 34657791 DOI: 10.1016/j.jcms.2021.09.018] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/13/2020] [Revised: 06/28/2021] [Accepted: 09/26/2021] [Indexed: 10/20/2022] Open
Abstract
The aim of this retrospective cohort study was to compare the recurrence rate and speech outcomes between two techniques for palatal fistula closure of cleft palate (CP). Patients with CP who underwent secondary palatal fistula closure using the single hinge-flap method with double-breasted mattress suture (hinge-flap group) and those who were treated with the conventional sliding palatal flap method (sliding-flap group) were retrospectively evaluated for demographic and perioperative variables. Recurrence rate of palatal fistula, perceptual speech outcomes, and nasalance scores were further reviewed in patients who met the inclusion criteria. A total of 31 patients, 21 in the hinge-flap group and 10 in the sliding-flap group, were included in this study. The fistula recurrence rate in the hinge-flap group (0%) was significantly lower than that in the sliding-flap group (30.0%) (P = 0.027). In the speech assessment, hypernasality and nasalance scores decreased post-operatively in both groups and significance was observed in the hinge-flap group (P = 0.013, P < 0.001, respectively). Articulation disorders were significantly improved in the hinge-flap group (P = 0.001). Within the limitations of the study it seems that the single hinge-flap method with double-breasted mattress suture should be preferred whenever appropriate.

Abstract
OBJECTIVE Velopharyngeal insufficiency (VPI) remains a known complication of primary palatoplasty. We sought to identify factors associated with the incidence of VPI and create a predictive model for VPI development in our population. DESIGN A single-institution, retrospective review. SETTING Multidisciplinary clinic in a tertiary academic institution. PATIENTS A total of 453 consecutive patients undergoing primary palatoplasty from 1999 to 2016 were reviewed. Inclusion required follow-up past age 5. Patients who were non-verbal, and thus unable to undergo speech evaluation, were excluded. MAIN OUTCOME MEASURES Primary outcome was VPI, defined as revision palatoplasty or recommendation by speech-language pathology. RESULTS Of 318 patients included, 179 (56%) were male. Median age at primary repair was 1.0 years (0.9-1.1) with a median age of 8.8 years at last follow-up. One hundred nineteen (37%) patients developed VPI at a median age of 5.0 years (3.8-6.5). Higher rates were seen with posterior fistula (65% vs 14%, P <.01) and straight-line repair (41% vs 9%, P <.01), with lower rates in patients with Veau I clefts (22% vs 39%, P <.05). Patients with VPI were older at last follow-up. Following multivariate regression, factors remaining significant were posterior fistula (odds ratio [OR]: 11.3, 95% CI: 6.1-22.0), primary Furlow repair (OR: 0.18, 95% CI: 0.03-0.68), genetic diagnoses (OR: 2.92, 95% CI: 1.1-7.9), and age at last follow-up (OR: 1.11, 95% CI: 1.01-1.2). CONCLUSIONS Length of follow-up, posterior fistulae, and genetic diagnoses are associated with VPI formation. Furlow repair may protect against formation of VPI. Use of allograft, Veau class, birth type, birth weight, and race are not independently associated with VPI formation.

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

Abstract
Objective: To report speech and velopharyngeal function (VPF) outcomes, and surgical characteristics, at age 5 following early complete palate closure using the Sommerlad protocol. Design: A retrospective, descriptive, cross-sectional consecutive series. Setting: A regional twin site center; a district general hospital and tertiary children’s hospital. Participants: Between 1993 and 2006, 877 participants underwent surgery; 712 (81%) were eligible for inclusion; 391 (55%) were included, 321 (45%) excluded. Thirteen percent had bilateral cleft lip and palate (CLP), 40% unilateral CLP, and 47% isolated cleft palate. Intervention: Lip and vomerine flap repair at 3 months of age (BCLP, UCLP) with soft palate closure using radical muscle dissection and retropositioning at a mean age of 6.6 months, range 4 to 23 months, as described and undertaken by Sommerlad. Outcome Measures: Velopharyngeal Composite (VPC) CAPS-A and articulation summary scores derived from analysis using the Cleft Audit Protocol for Speech-Augmented. Results: A VPC-SUM CAPS-A score of “0” was found in 97% reflecting adequate VPF; 73% had no cleft articulation difficulties. The BCLP group had the poorest articulation. Secondary speech surgery rate was 2.6% and 10.7% had fistula repair. Levator muscle quality and degree of retropositioning was associated with speech outcomes related to VPF. 2.6% had current features of VPI. Conclusions: Complete palate closure by around 6 months of age by the surgeon who described the technique led to excellent perceived VPF and very good speech outcomes at age 5, with less speech therapy and secondary speech surgery than commonly reported. These findings serve as a benchmark for the Sommerlad protocol and technique.
