RESUMO
Craniofacial morphogenesis requires complex interactions involving different tissues, signaling pathways, secreted factors and organelles. The details of these interactions remain elusive. In this study, we have analyzed the molecular mechanisms and homeostatic cellular activities governing soft palate development to improve regenerative strategies for individuals with cleft palate. We have identified canonical Wnt signaling as a key signaling pathway primarily active in cranial neural crest (CNC)-derived mesenchymal cells surrounding soft palatal myogenic cells. Using Osr2-Cre;ß-cateninfl/fl mice, we show that Wnt signaling is indispensable for mesenchymal cell proliferation and subsequently for myogenesis through mediating ciliogenesis. Specifically, we have identified that Wnt signaling directly regulates expression of the ciliary gene Ttll3. Impaired ciliary disassembly leads to differentiation defects in mesenchymal cells and indirectly disrupts myogenesis through decreased expression of Dlk1, a mesenchymal cell-derived pro-myogenesis factor. Moreover, we show that siRNA-mediated reduction of Ttll3 expression partly rescues mesenchymal cell proliferation and myogenesis in the palatal explant cultures from Osr2-Cre;ß-cateninfl/fl embryos. This study highlights the role of Wnt signaling in palatogenesis through the control of ciliary homeostasis, which establishes a new mechanism for Wnt-regulated craniofacial morphogenesis.

BACKGROUND: The double-opposing Z-plasty is a fundamental approach for cleft palate repair. Recently, some surgeons have begun implementing a single Z-Plasty, igniting discussions on the most effective technique for enhancing postoperative outcomes. Consequently, this study sought to evaluate the outcomes of employing single and double Z-plasties within the modified Sommerlad-Furlow technique. METHODS: 116 cleft palate patients undergoing primary surgical repair were divided into two groups: those treated with the Sommerlad-Furlow method using a double-opposing Z-plasty (S.F.2.Z.P. group, n = 58) and those receiving a single nasal Z-plasty (S.F.1.Z.P. group, n = 58). Data on cleft type and width, soft palate length, palatal fistula, and velopharyngeal function were collected. Mann-Whitney test compared the mean values between groups. RESULTS: The S.F.2ZP group demonstrated a statistically significant increase in soft palate length compared to those in the S.F.1ZP group (p = 0.008). However, the S.F.1ZP group demonstrated adequate soft palate length (7.9 ± 2.8 mm) compared to the S.F.2ZP group (9.3 ± 2.8 mm). The velopharyngeal function was good in both groups, with no significant differences (P = 0.52). While the proper velopharyngeal closure was 81% in the S.F.1ZP group and 87.9% in the S.F.2ZP group, velopharyngeal insufficiency was 10.3% and 5.2%, respectively. The rates of persistent palatal fistula were 5.2% in the S.F.1ZP group and 3.4% in the S.F.2ZP group, with no significant differences found between both groups (P = 0.64). CONCLUSIONS: There were no significant differences in crucial outcomes such as velopharyngeal function and the incidence of persistent palatal fistulas, indicating the effectiveness of both techniques. While the double-opposing Z-plasty demonstrated a statistically significant increase in soft palate length, the a nasal Z-plasty demonstrated adequate soft palate length which sufficiently enables effective velopharyngeal closure. These outcomes suggest that a single Z-plasty is both effective and easy to perform, making it a valuable surgical approach for achieving the desired outcomes.. CLINICAL RELEVANCE: The current study suggests that although the soft palate may not be as elongated with nasal Z-plasty alone compared to the double Z-plasty, it sufficiently enables effective velopharyngeal closure.

OBJECTIVE: The objective of this study was to investigate how cleft surgeons classify palatal fistulas. We focused on three different anatomical locations (ie, hard palate, soft palate, junction hard/soft palate) to analyze agreement/disagreement at various anatomical locations. DESIGN: Cross-sectional survey study. PARTICIPANTS: Participants in an international webinar that focused on palatal fistula treatment were included. INTERVENTION: Participants were presented with a survey pre- and post-webinar. MAIN OUTCOMES: Frequency of used classification systems for classifying oronasal fistulas and the inter-rater reliability of the Pittsburgh classification system. RESULTS: A total of 141 participants completed the questionnaires prior to the webinar and 109 participants completed the survey after the webinar. In total, four classification systems were used (ie, Pittsburgh, Pakistan Comprehensive Fistula Classification [PCFC], anatomical and 'other'). The Pittsburgh classification was the most commonly used system in all cases. However, Pittsburgh inter-rater reliability was low (κ = 0.136 pre-webinar, and κ = 0.174 post-webinar). Surprisingly, a substantial shift was observed from the anatomical to Pittsburgh classification after the webinar, indicating increased awareness of the usability of the Pittsburgh classification system. CONCLUSIONS: This study demonstrates a large heterogeneity with regards to the classification of cleft palate fistulas. Interestingly, a shift was observed from the anatomical to Pittsburgh classification after the webinar. However, the inter-rater reliability for using the Pittsburgh classification was low. Classifying palatal fistulas in a homogenous fashion could enhance comparison of primary palate repair and could improve treatment of palatal fistulas.

BACKGROUND: This study characterizes the potential loss of velar length in patients with a wide cleft and rescue of this loss of domain by local flap reconstruction, providing anatomic evidence in support of primary lengthening of the soft palate during palatoplasty. METHODS: A retrospective review was conducted of all patients with a cleft palate at least 10mm in width, who underwent primary palatoplasty with a buccal flap prior to 18 months of age over a 2-year period. All patients underwent primary palatoplasty with horizontal transection of the nasal mucosa, which was performed after nasal mucosa repair, but prior to muscular reconstruction. The resulting palatal lengthening was measured and the mucosal defect was reconstructed with a buccal flap. RESULTS: Of the 22 patients included, 3 (13.6%) had a history of Pierre Robin sequence, and 5 (22.7%) had an associated syndrome. No patients had a Veau I cleft, 7 (31.8%) had a Veau II, 12 (54.5%) had a Veau III, and 3 had (13.6%) a Veau IV cleft. All patients had a right buccal flap during primary palatoplasty. The mean cleft width at the posterior nasal spine was 10.6 ± 2.82mm, and mean lengthening of the velum after horizontal transection of the nasal mucosa closure was 10.5 ± 2.23mm. There were 2 (9.1%) fistulas, 1 (4.5%) wound dehiscence, 1 (4.5%) 30-day readmission, and no bleeding complications. CONCLUSIONS: Patients with a wide cleft palate have a potential loss of 1cm velar length. The buccal flap can rescue the loss of domain in palatal length, and potentially improve palatal excursion.

OBJECTIVE: The aim of this study was to cephalometrically evaluate the pharyngeal morphology in adults with unoperated Submucous Cleft Palate (SMCP), adults with unoperated Overt Cleft Palate (OCP), and adults without clefts. DESIGN: This study employed a retrospective cross-sectional design. Lateral cephalometric radiography was performed on three groups of adults: 1) 29 with unrepaired SMCP; 2) 41 with unrepaired OCP; and 3) 39 without clefts, who served as controls. One-way ANOVA and rank-sum tests were used for intergroup comparisons. P value was set at .05. RESULTS: The soft palate length and the ratio of soft palate length to pharyngeal depth were significantly lower in subjects with unoperated SMCP and OCP than in non-cleft controls. Significant differences were also observed in pharyngeal depth, nasopharyngeal depth, and posterior pharyngeal wall thickness between subjects with unoperated OCP and non-cleft controls. CONCLUSIONS: Pharyngeal morphology differs significantly between individuals with and without clefts, particularly in soft palate length and the ratio of soft palate length to pharyngeal depth.
RESUMO
It remains a significant challenge in prosthetic rehabilitation for combined hard and soft palate defects on account of two primary reasons. At first, conventional impressions can hardly get an accurate analogue and usually bring about a terrible experience for the patients. Secondly, conventional hard denture base resins used in obturator prostheses exhibit limitations in marginal sealing, undercut retention, and elastic buffering when in contact with the soft palate. This article presents a case where combined hard and soft palate defects were successfully and rapidly reconstructed by using digital intraoral impression technology and denture soft reline material.
RESUMO
OBJECTIVE: The objective of this study was to use data from Smile Train's global partner hospital network to identify patient characteristics that increase odds of fistula and postoperative speech outcomes. DESIGN: Multi-institution, retrospective review of Smile Train Express database. SETTING: 1110 Smile Train partner hospitals. PATIENTS/PARTICIPANTS: 2560 patients. INTERVENTIONS: N/A. MAIN OUTCOME MEASURE(S): Fistula occurrence, nasal emission, audible nasal emission with amplification (through a straw or tube) only, nasal rustle/turbulence, consistent nasal emission, consistent nasal emission due to velopharyngeal dysfunction, rating of resonance, rating of intelligibility, recommendation for further velopharyngeal dysfunction assessment, and follow-up velopharyngeal dysfunction surgery. RESULTS: The patients were 46.6% female and 27.5% underweight by WHO standards. Average age at palatoplasty was 24.7 ± 0.5 months and at speech assessment was 6.8 ± 0.1 years. Underweight patients had higher incidence of hypernasality and decreased speech intelligibility. Palatoplasty when under 6 months or over 18 months of age had higher rates of affected nasality, intelligibility, and fistula formation. The same findings were seen in Central/South American and African patients, in addition to increased velopharyngeal dysfunction and fistula surgery compared to Asian patients. Palatoplasty technique primarily involved one-stage midline repair. CONCLUSIONS: Age and nutrition status were significant predictors of speech outcomes and fistula occurrence following palatoplasty. Outcomes were also significantly impacted by location, demonstrating the need to cultivate longitudinal initiatives to reduce regional disparities. These results underscore the importance of Smile Train's continual expansion of accessible surgical intervention, nutritional support, and speech-language care.

Pseudoxanthoma elasticum (PXE) is an autosomal recessive genetic disorder characterized by aberrant fragmentation and calcification of elastic fibers, leading to characteristic cutaneous, ophthalmic, and cardiovascular manifestations. PXE demonstrates significant phenotypic variability; involvement of the oral mucosa may be the only clue to the diagnosis. Reports on mucous membrane involvement in PXE are scarce. Here, we present a case of PXE-like changes in the oral cavity. A 70-year-old male patient presented with a painless leukoplakic lesion on the soft palate. Biopsy revealed numerous degenerated fibers in the lamina propria. Verhoeff-van Gieson and von Kossa staining confirmed their identity as calcified elastic fibers. A histopathological diagnosis of PXE-like changes was made; the patient was referred to ophthalmology where angioid streaks were visualized fundoscopically. PXE-like changes in the absence of the characteristic genetic mutation have also been reported with or without systemic manifestations. Furthermore, PXE-like changes have been reported in up to 10% of oral biopsy specimens undertaken without clinical suspicion for PXE. Therefore, the significance of such changes in isolation is unclear. Clinicians and pathologists should be aware of the potential oral manifestations of PXE to facilitate prompt diagnosis and subspecialist referral.

OBJECTIVE: The aim of this study is to analyze functional outcomes of soft palate reconstruction after oncologic surgery. METHODS: This study was conducted in conformity with the PRISMA statement. A single arm meta-analysis was performed for feeding tube dependence (FTD) (primary outcome), velopharyngeal insufficiency (VPI) and hypernasality (HN) (secondary outcomes) incidences. RESULTS: A total of 510 patients (males: 77.75%, n = 353/454) with a median age of 58 years (n = 480/510; 95% CI 57.0-61.0) who underwent soft palate surgical resection with primary reconstruction were included. Overall, the cumulative FTD rate was 1.55% (n = 28/510; 95% CI 0.24-3.96%), the VPI rate was 22.18% (n = 119/379; 95% CI 12.99-33.02%), and the HN rate was 33.01% (n = 88/234; 95% CI 19.03-46.61%). CONCLUSIONS: Soft palate reconstruction results in a low incidence of FTD, and most patients resume a full oral diet. Both obturators, primary closure, local and free flaps seem good reconstructive options. Nevertheless, more specific postoperative functional deficiencies like VPI and HN owns higher incidences, potentially affecting the quality of the swallowing and speaking function and the patient's quality of life.

Benign salivary gland tumors are rarely found in children and adolescents compared with adults. Pleomorphic adenomas (PAs), the most common benign salivary gland tumor, account for only 1% of all head and neck lesions and fewer than 5% of all salivary gland tumors in individuals under the age of 16 years. The data on palatal PA in the first 2 decades of life is confined to published case reports and case series. To date, there has never been a report of palatal PA in a patient with cleft lip and palate. Here we describe an adolescent female with bilateral cleft lip and palate with PA of the hard and soft palate who underwent wide local excision and reconstruction with a buccal fat pad and buccal myo-mucosal flap.

OBJECTIVE: Identification of at risk patients before surgery could facilitate improved clinical communication, care pathways and postoperative pain management. DESIGN: A retrospective cohort study was performed in all infants who had undergone cleft palate repair. SETTING: Tertiary Institutional. PARTICIPANTS: Infants < 36 months of age who underwent primary repair of cleft palate between March 2016 and July 2022. INTERVENTION: Requirement for analgesic intervention in the post operative care unit. MAIN OUTCOME MEASURE: Adverse perioperative event defined as pain or distress. Secondary outcomes were the incidence of airway obstruction, hypoxemia or unplanned intensive care admission. RESULTS: Two hundred and ninety one patients (14.6 months,10.1â kg weight) were included. Cleft distribution included submucous (5.2%), Veau I (23.4%), Veau 2 (38.1%), Veau 3 (24.4%), and Veau 4 (8.9%). Overall 35% of 291 infants undergoing cleft palate repair experienced pain or distress requiring opiate intervention in the first hour after surgery. Infants with a Veau 4 cleft palate had 1.8 times and Veau 2 cleft palate had 1.5 times the risk of postoperative pain compared to infants with Veau 1 cleft palate (relative risk 1.82, 95%CI 1.04-3.18 and 1.49, 95%CI 0.96-2.32 respectively). The use of bilateral above elbow arm splints was significantly associated with postoperative pain or distress (odds ratio 2.23, 95%CI 1.01-5.16). CONCLUSIONS: Post operative pain requiring intervention in PACU is common despite adequate intraoperative multimodal analgesia, local anaesthesia infiltration and postoperative opiate infusions. Infants undergoing soft palate alone or submucous palate repair may require less perioperative opiates.
RESUMO
OBJECTIVE: The addition of a uvular flap (PFU) was hypothesized to improve outcomes over standard pharyngeal flap (PF) for correction of velopharyngeal dysfunction. We report differences in outcomes of PF vs PFU at our institution. DESIGN: Retrospective cohort study. SETTING: Tertiary children's hospital. PATIENTS: Children who underwent PF or PFU with the three highest-volume surgeons at our institution in 2004-2017. OUTCOME MEASURES: We examined differences in complications between groups, frequency and type of revision surgery, and speech-related measures including nasometry, pressure-flow testing (PFT) and perceptual speech analysis (PSA). RESULTS: 160 patients were included, 41 PF and 119 PFU (including 18 with Hogan technique). Patients undergoing PFU were older (7.6â yr vs 6.0â yr; p = 0.037) and more likely to have cleft palate (63/119 vs 14/41; p = 0.047). There was no significant difference in complications. With PFU, a decrease in airspace contracting revision surgeries was noted, (4/119 vs 8/41; p = 0.002) which drove a reduction in revision surgery of all types (7/119 vs 13/41; p = 0.033). However, patients that did undergo revision surgery after PFU underwent more revision procedures (p = 0.032). PSA scores were found to be lower (less hypernasal) after PFU (p = 0.009) compared to PF. Objective speech measures had varying results, with nasometry demonstrating a significant difference between groups (p = 0.001), while PFT (p = 0.525) did not demonstrate a statistical difference. CONCLUSION: The use of a uvular lining flap in pharyngeal flap surgery may be associated with improved long term surgical outcomes, including both improvements in subjective and objective testing and a lower rate of revision surgery, without increased complications.
RESUMO
Oronasal fistula (ONF) is a common complication encountered after palatoplasty. Repair is indicated when symptoms impact speech and swallowing. In spite of the variety of surgical approaches described to repair these defects, recurrence rates remain high. Traditionally, successful closure is said to be achieved in using a double-layered approach due to the three-dimensional aspect of the defect. The extent of the fistula into the nasal cavity has incited an increased curiosity in using local endonasal flaps. In recent years, endonasal reconstructive procedures have seen increased interest and application, from cranial base defect repairs to orbital reconstruction and beyond. The nasoseptal (NSF) and inferior turbinate flaps (ITF) possess a robust arterial supply and an exceptional reach with excellent results demonstrated in large defect repair. However, the use of these flaps in ONF repair is scarcely discussed in the literature, and their effectiveness is relatively undetermined. In this manuscript, we present a series of three patients who underwent a triple layer ONF closure, with the oral portion incorporating a turn-in mucosal flap plus a local palate rotation flap or greater palatine artery pedicled-rotation flap, and a NSF or an ITF for the nasal portion of the defect.

Web-based health information is the leading source of medical knowledge for patients and families. The American Medical Association (AMA) and US Department of Health and Human Services recommend reading material be at or below a sixth-grade reading level. This study aimed to evaluate and compare the readability of the most popularly searched cleft lip and/or palate (CL/P) and other craniofacial syndrome (CFS) websites.Google searches for "cleft lip," "cleft palate," and "craniofacial syndromes" were performed to identify the top 40 websites in an incognito window with the location set to the United States. Flesch Reading Ease Score (FRES) was used to determine ease of reading from 0 (most difficult) to 100 (greatest ease of reading) and Flesch-Kincaid Reading Grade (FKGL) for website content and compared between websites using an FRES of 80 to 90 and FKGL of 6.0 to 6.9 for a sixth-grade reading level.Readability was low for all sites with 6 CL/P websites and no CFS websites at or below a sixth-grade reading level. CL/P websites had FRES readability scores of 58.5 ± 12.3 and were at a 9.4 ± 2.3 grade level. CFS websites had readability scores on the FRES of 39.8 ± 13.1 and were at a 10.8 ± 1.8 grade level.Web-based information related to CL/P and CFS is on average several grade levels above the recommended sixth-grade reading level. Online information for CL/P and CFS may need to be revised to improve understanding for the public and families.

OBJECTIVE: Approximately 30% of patients with a history of repaired cleft palate (CP) go on to suffer from velopharyngeal dysfunction (VPD). This study discusses the operative management of VPD and postoperative speech outcomes in a cohort of CP patients. SETTING: An academic tertiary pediatric care center. METHODS: Retrospective cohort study. PATIENTS: Patients with history of repaired CP (Veau I-IV) who underwent operative management of VPD between January 1st, 2010 and December 31st, 2020. Operative modalities were posterior pharyngeal flap (PPF), sphincter pharyngoplasty (SPP), Furlow palate re-repair, and buccal myomucosal flap palate lengthening (PL). OUTCOME MEASURES: The primary outcome measure is postoperative speech improvement evaluated by the Pittsburgh Weighted Speech Scale (PWSS). RESULTS: 97 patients met inclusion criteria. 38 patients with previous straight-line primary palatoplasty underwent Furlow re-repair; these patients were significantly younger (7.62 vs 11.14, P < .001) and were more likely to have severe VPD per PWSS (OR 4.28, P < .01, 95% CI 1.46-12.56) when compared to VPD patients with previous Furlow repair. 21.1% of these patients required an additional non-revisional VPD procedure. The remaining patients underwent a non-revision procedure (26 PPF, 22 SPP, 11 PL); all experienced significant (P < .001 on paired t-test) reductions in PWSS total and subgroup VPD severity scores without difference in improvement between operation types. SPP was statistically associated with all-cause complication (OR 2.79, 95% CI 1.03-7.59, P < .05) and hyponasality (OR 3.27, 95% CI 1.112-9.630, P < .05). CONCLUSION: Furlow re-repair reduced need for additional VPD operations. Speech outcomes between non-revisional operations are comparable, but increased complications were seen in SPP.
RESUMO
OBJECTIVE: To design a technique of palate repair with predictable Velo Pharyngeal (VP) closure and normal speech - 'Suspension Palatoplasty' in speaking unrepaired Cleft Palate (CP) patients. To evaluate the results of patients with CP operated using the technique of 'Suspension palatoplasty' from 2014 -2018 in terms of surgical complications and speech outcomes. DESIGN: An ambi-spective longitudinal clinical study. SETTING: Comprehensive cleft care clinic in a private trust hospital. PATIENTS/ PARTICIPANTS: Patients above 6 years of age with isolated CP, cleft lip and palate (CLP), operated using 'Suspension Palatoplasty' technique between 2014 and 2018 were included with minimum follow up period of 5 years. Subjective speech evaluation was done by two speech therapists and analysed. INTERVENTION: Author designed the technique of 'Suspension Palatoplasty' which aims to suspend the soft palate repaired by 'Hybrid Palatoplasty' technique, close to the nasopharynx using narrow pharyngeal flap with the pedicle based superiorly at adenoids, for an acceptable VP closure. MAIN OUTCOME MEASURES: Speech outcome and surgical complications were assessed. RESULTS: Out of 94 cases operated with age ranging from 6 to 45 years, 59 (62.8%) had normal speech, 12 (12.8%) had articulation errors but with no Velo-Pharyngeal Insufficiency (VPI) and 23 patients (24.4%) had hypernasality/ nasal emission (Suspected VPI). None of them had difficulty in breathing but one patient had snoring. CONCLUSION: 'Suspension Palatoplasty' is a simple primary operation with excellent speech outcomes with no obstructive sequelae in patients with speaking unrepaired cleft palate.
RESUMO
OBJECTIVE: To compare the effectiveness of short-term ventilation tubes compared to surveillance on conductive hearing loss in children with non-syndromic orofacial clefting involving the muscular palate. INTRODUCTION: Chronic otitis media with effusion is a common finding in children with cleft palate. The accepted convention is insertion of short-term ventilation tubes at the time of palate repair, but some centres are choosing conservative management. Each approach has its advantages but there is currently no consensus on the most appropriate management in children with non-syndromic cleft palate. INCLUSION CRITERIA: Children <18 years with cleft lip and palate, or isolated cleft palate, not associated with a genetic syndrome, who have been diagnosed with chronic otitis media with effusion. METHODS: A systematic search of MEDLINE, CINAHL, Embase and Scopus databases was conducted. Grey literature searches were conducted through Central Register of Controlled Trials, Clinicaltrials.gov and ProQuest. Two reviewers screened the studies, conducted critical appraisal, assessed the methodological quality, and extracted the data. Where possible, studies were pooled in statistical meta-analysis with heterogeneity being assessed using the standard Chi-squared and I2 tests. RESULTS: Four studies met the inclusion criteria but were of low quality with a moderate risk of bias. Only data on hearing thresholds could be pooled for analysis which found no statistically significant difference. Other outcomes were presented in narrative form. Certainty of evidence for all outcomes was deemed low to very low using GRADE criteria. CONCLUSIONS: No definitive conclusions can be drawn regarding most effective management at improving conductive hearing loss. Missing data and inconsistent reporting of outcomes limited capacity for pooled analysis.
RESUMO
OBJECTIVE: Buccal myomucosal flaps (BMF) anatomically lengthen the palate in the treatment of velopharyngeal insufficiency (VPI). We systematically reviewed the existing literature on speech outcome of BMF palatal lengthening. DESIGN: Three databases were used to identify studies of interest published in English. Studies that did not use standardized speech assessments were excluded. PRISMA checklist was followed, and the risk of bias in the included studies was assessed. SETTING: Long-term follow up of patients. PATIENTS: With history of cleft palate presenting with VPI. INTERVENTION: BMF palatal lengthening. MAIN OUTCOME MEASURE: Random-effects model meta-analyses were performed for hypernasality, intelligibility, and nasal air emission score improvements, which were derived from reported preoperative and postoperative scores, and controlled for variability of scales and timing of postoperative assessment. RESULTS: From the initial 7115 articles, 13 were included in this review. Two of these had a significant patient overlap and a study with a smaller patient population was excluded. All 12 included articles met the National Institutes of Health Quality Assessment Tool criteria. Six retrospective studies evaluated 230 patients and six prospective studies evaluated 181 patients. The most common indications for BMF were large size of the velopharyngeal gap and prior surgery for VPI. Meta-analyses demonstrated effect sizes below zero, confirming the improvement of standardized assessment scores in patients with VPI after BMF palatal lengthening. Egger regressions revealed low risk of publication bias. CONCLUSIONS: BMF palatal lengthening provides adequate treatment for VPI in patients with large velopharyngeal gap size and a history of prior unsuccessful surgery.
RESUMO
Surgical intervention can contribute to the development of velopharyngeal insufficiency (VPI) leading to hypernasality and regurgitation. In this case, a patient with a history of bilateral buccal flaps used for her primary CP repair presented to clinic with hypernasality and VPI as assessed by speech exam and imaging. She underwent repeat bilateral buccal flap palatal lengthening with division of the pedicles 3 months later. Three months after her division, her hypernasality score improved from moderate to mild and her posterior gap decreased. This study concluded buccal flaps can be used a second time for patients needing palatal revisions for VPI.
RESUMO
OBJECTIVE: Describe the first hybrid global simulation-based comprehensive cleft care workshop, evaluate impact on participants, and compare experiences based on in-person versus virtual attendance. DESIGN: Cross-sectional survey-based evaluation. SETTING: International comprehensive cleft care workshop. PARTICIPANTS: Total of 489 participants. INTERVENTIONS: Three-day simulation-based hybrid comprehensive cleft care workshop. MAIN OUTCOME MEASURES: Participant demographic data, perceived barriers and interventions needed for global comprehensive cleft care delivery, participant workshop satisfaction, and perceived short-term impact on practice stratified by in-person versus virtual attendance. RESULTS: The workshop included 489 participants from 5 continents. The response rate was 39.9%. Participants perceived financial factors (30.3%) the most significant barrier and improvement in training (39.8%) as the most important intervention to overcome barriers facing cleft care delivery in low to middle-income countries. All participants reported a high level of satisfaction with the workshop and a strong positive perceived short-term impact on their practice. Importantly, while this was true for both in-person and virtual attendees, in-person attendees reported a significantly higher satisfaction with the workshop (28.63 ± 3.08 vs 27.63 ± 3.93; P = .04) and perceived impact on their clinical practice (22.37 ± 3.42 vs 21.02 ± 3.45 P = .01). CONCLUSION: Hybrid simulation-based educational comprehensive cleft care workshops are overall well received by participants and have a positive perceived impact on their clinical practices. In-person attendance is associated with significantly higher satisfaction and perceived impact on practice. Considering that financial and health constraints may limit live meeting attendance, future efforts will focus on making in-person and virtual attendance more comparable.
