OBJECTIVE/UNASSIGNED:Utilize 3-dimensional (3D) photography to evaluate the nasolabial changes in infants with bilateral cleft lip and palate (BCLP) who underwent nasoalveolar molding (NAM) and primary reconstructive surgery. DESIGN/UNASSIGNED:coordinates to obtain the linear and angular measurements. Nasal form changes were measured and analyzed between T1 (0.5 months old), T2 (5 months old), and T3 (6 months old). Intraclass correlation coefficient was performed for intrarater reliability. Averaged data from the 3D images was statistically analyzed from T1 to T2 and T2 to T3 with Wilcoxon tests. Unaffected infant norms from the Farkas publication were used as a control sample. RESULTS/UNASSIGNED:After NAM therapy, statistically significant changes in the position of subnasale and labius superius improved nasolabial symmetry. Both retruded after NAM were displaced downward after NAM and surgical correction with respect to soft tissue nasion. The nasal tip's projection was maintained with NAM and surgical correction. The columella lengthened from 1.4 to 4.71 mm following NAM. CONCLUSIONS/UNASSIGNED:There was a significant improvement in the nasolabial anatomy after NAM, and this was further enhanced after primary reconstructive surgery.

BACKGROUND:The authors present outcomes analysis of the nasoalveolar molding treatment protocol in patients with a cleft followed from birth to facial maturity. METHODS:A single-institution retrospective review was conducted of cleft patients who underwent nasoalveolar molding between 1990 and 2000. Collected data included surgical and orthodontic outcomes and incidence of gingivoperiosteoplasty, alveolar bone grafting, surgery for velopharyngeal insufficiency, palatal fistula repair, orthognathic surgery, nose and/or lip revision, and facial growth. RESULTS:One hundred seven patients met inclusion criteria (69 with unilateral and 38 with bilateral cleft lip and palate). Eighty-five percent (91 of 107) underwent gingivoperiosteoplasty (unilateral: 78 percent, 54 of 69; bilateral: 97 percent, 37 of 38). Of those patients, 57 percent (52 of 91) did not require alveolar bone grafting (unilateral: 59 percent, 32 of 54; bilateral: 54 percent, 20 of 37). Twelve percent (13 of 107) of all study patients underwent revision surgery to the lip and/or nose before facial maturity (unilateral: 9 percent, six of 69; bilateral: 18 percent, seven of 38). Nineteen percent (20 of 107) did not require a revision surgery, alveolar bone grafting, or orthognathic surgery (unilateral: 20 percent, 14 of 69; bilateral: 16 percent, six of 38). Cephalometric analysis was performed on all patients with unilateral cleft lip and palate. No significant statistical difference was found in maxillary position or facial proportion. Average age at last follow-up was 20 years (range, 15 years 4 months to 26 years 10 months). CONCLUSIONS:Nasoalveolar molding demonstrates a low rate of soft-tissue revision and alveolar bone grafting, and a low number of total operations per patient from birth to facial maturity. Facial growth analysis at facial maturity in patients who underwent gingivoperiosteoplasty and nasoalveolar molding suggests that this proposal may not hinder midface growth. CLINICAL QUESTION/LEVEL OF EVIDENCE/METHODS:Therapeutic, IV.

Background/Purpose: Newborns with cleft lip and/or palate (CLP) exceed 100 000 per year in low- and middle-income countries (LMICs). Patients, if left untreated, are at high risk of morbidity, due to functional deficits, malnutrition, aspiration, and infections. Limited resources in LMICs create barriers for establishing Interdisciplinary Cleft Care programs. Surgical missions driven by nonprofit organizations have been able to partially address this need, but their ability to promote long-term sustainable cleft care has come to a question. Simulation-based training has emerged as an essential tool for enhancing medical education and training. Global Smile Foundation, a nonprofit organization, is a leader in the establishment of Interdisciplinary Cleft Care programs, with its volunteers being involved in cleft care for over 3 decades. We were able to demonstrate the efficacy of our first Simulation-Based Comprehensive Cleft Care Workshop (SBCCW), in the Middle East-North Africa (MENA) region, and its wide acceptance by our recipients. In the current study, we want to prove the effectiveness and successfulness of our second SBCCW, in Latin America. Methods/Description: Our second SBCCW took place in Lima, Peru, in October 2019. Hands-on simulations of CLP repair using highfidelity CLP simulators were also provided to our participants. Participants were asked to complete a satisfaction survey at the end. Attendees were also asked about the obstacles facing cleft care in their countries and the possible interventions to overcome these obstacles. Short-term (at the end of the SBCCW) and medium-term (6 months later) follow ups were conducted by our team collecting data about improvements in the participants' competence, performance, outcomes, clinical care, and whether the SBCCW has changed their practice. Procedural confidence for pre- and postsimulation was evaluated using the psychometrically validated tool for measuring selfconfidence during surgical learning. Descriptive statistics were used for the collected data. Data analyses were performed using the Statistical Package for the Social Sciences. XXResult(s): Ninety-eight of the 198 participants from 29 different countries filled the satisfaction survey at the end of the workshop. The 2 most common barriers to cleft care in LMICs identified by our participants are the absence of financial support and the absence of multidisciplinary teams. Respondents claimed an improvement in their procedural confidence after the simulation sessions. Respondents had consistent short-term and medium-term impressions about the SBCCW positively impacting their competence, performance, outcomes, clinical care, and even changing their practice. XXConclusion(s): This study provides evidence that implementation of a SBCCW leads to a significantly improved procedural confidence, as well as a sustained positive impact on the clinical practice of the participants, reinforcing its role as a cleft care capacity-building tool

OBJECTIVE/UNASSIGNED:This study evaluates skeletal and dental outcomes of LeFort I advancement surgery in patients with cleft lip and palate (CLP) with varying degrees of maxillary skeletal hypoplasia. DESIGN/UNASSIGNED:Retrospective study. METHOD/UNASSIGNED:: ≤-10 mm. PARTICIPANTS/UNASSIGNED:Fifty-one patients with nonsyndromic CLP with hypoplastic maxilla who met inclusion criteria. INTERVENTION/UNASSIGNED:LeFort I advancement. MAIN OUTCOME MEASURE/UNASSIGNED:Skeletal and dental stability post-LeFort I surgery at a 1-year follow-up. RESULTS/UNASSIGNED:At T2, LeFort I surgery produced an average correction of maxillary hypoplasia by 6.4 ± 0.6, 8.1 ± 0.4, and 10.7 ± 0.8 mm in the mild, moderate, and severe groups, respectively. There was a mean relapse of 1 to 1.5 mm observed in all groups. At T3, no statistically significant differences were observed between the surgical groups and controls at angle Sella, Nasion, A point (SNA), A point, Nasion, B point (ANB), and overjet outcome measures. CONCLUSIONS/UNASSIGNED:LeFort I advancement produces a stable correction in mild, moderate, and severe skeletal maxillary hypoplasia. Overcorrection is recommended in all patients with CLP to compensate for the expected postsurgical skeletal relapse.

INTRODUCTION/UNASSIGNED:Nasal duplication is a rare congenital deformity with many subtypes including supernumerary nostril. The challenge of surgical correction is to achieve nasal symmetry and restore nasal airflow. However, there is no defined protocol for treatment, especially with regard to presurgical therapy. METHODS/UNASSIGNED:We performed a review of literature of studies reporting on patients with supernumerary nostril to complete this review. We then report on a patient with supernumerary nostril who was treated with nostril expansion therapy prior to surgical intervention. RESULTS/UNASSIGNED:We identified 59 cases of nostril duplication. Because of the rarity of the condition, treatment protocols varied greatly. For our patient, preoperative nasal appliance therapy was implemented for 3 months prior to surgical intervention. Patient was followed-up regularly for 1 year. DISCUSSION/UNASSIGNED:Although literature on nasal duplication is scarce, there is a general agreement that early intervention has psychological, anatomic, and functional benefits to the patient. In our case report, nostril expansion therapy was easy to implement and facilitated surgical reconstruction, resulting in aesthetic outcome and expanded airway 1 year postoperatively.

BACKGROUND/UNASSIGNED:The aim of this study is to assess the effect of nasoalveolar molding (NAM) versus no-NAM on nasal morphology in patients with unilateral cleft lip and palate (UCLP) at the time of nasal maturity. METHODS/UNASSIGNED:A retrospective, single-institution review was conducted on all non-syndromic patients with UCLP. Inclusion criteria included age 14 years or above, unilateral cleft repair at the time of infancy, and adequate photography taken at nasal maturity and prior to rhinoplasty. Exclusion criteria included age less than 14 years, syndromic diagnosis, and rhinoplasty prior to nasal maturity. Ten parameters were measured twice from standardized clinical photographs using the Dolphin Imaging Software for establishment of intrarater reliability. Subjective analysis was achieved through completion of the Asher McDade grading scale by 3 expert cleft practitioners. RESULTS/UNASSIGNED:Nostril height, columellar angle, alar cant, vertical alar height, alar height angle, nasofacial angle, and nasolabial angle were found to be significantly less severe in patients who had undergone NAM in conjunction with surgical repair when compared with those who had undergone surgical repair alone. Asher McDade grading revealed significant improvement in nasal form, nasal symmetry/deviation, nasal profile, vermillion border, and overall score in patients who underwent NAM compared to no-NAM. CONCLUSION/UNASSIGNED:The use of presurgical NAM during infancy can improve nasal symmetry and nasal proportions at the time of nasal maturity.

OBJECTIVE/UNASSIGNED:To assess social and demographic influences on caregiver success and difficulty with nasoalveolar molding (NAM). DESIGN/UNASSIGNED:Retrospective review identified patients who began NAM between April 22, 2013, and April 18, 2017, at the New York University Langone Medical Center. Records were reviewed, and the following sociodemographic data retrieved: parental marital status, parental ages, number of siblings, distance traveled to clinic, insurance coverage, concurrent medical conditions, and need for an interpreter. PATIENTS/UNASSIGNED:Patients were included if complete charting was available; 106 patients met the inclusion criteria; 79 patients with unilateral and 27 with bilateral clefts. OUTCOME MEASURES/UNASSIGNED:Chart entries indicating incorrect appliance usage, emergency visits, phone calls, and noncompliance were recorded. Alveolar cleft gap closure was measured on pre- and posttreatment models in unilateral cases. Multiple regression analyses were performed to assess the influence of social variables on these outcomes. RESULTS/UNASSIGNED:= .019). CONCLUSIONS/UNASSIGNED:Alveolar cleft gap closure was more successful for older fathers, younger mothers, and married couples. Married couples were also less likely to experience treatment difficulties such as incorrect appliance usage or inadequate duration of wear, as were those with private insurance coverage.

OBJECTIVE/UNASSIGNED:Evaluate simulation-based comprehensive cleft care workshops as a reproducible model for education with sustained impact. DESIGN/UNASSIGNED:Cross-sectional survey-based evaluation. SETTING/UNASSIGNED:Simulation-based comprehensive cleft care workshop. PARTICIPANTS/UNASSIGNED:Total of 180 participants. INTERVENTIONS/UNASSIGNED:Three-day simulation-based comprehensive cleft care workshop. MAIN OUTCOME MEASURES/UNASSIGNED:Number of workshop participants stratified by specialty, satisfaction with the workshop, satisfaction with simulation-based workshops as educational tools, impact on cleft surgery procedural confidence, short-term impact on clinical practice, medium-term impact on clinical practice. RESULTS/UNASSIGNED:< .001) surgery procedural confidence following the simulation sessions. Participants also reported a positive short-term and medium-term impact on their clinical practices. CONCLUSION/UNASSIGNED:Simulation-based comprehensive cleft care workshops are well received by participants, lead to improved cleft surgery procedural confidence, and have a sustained positive impact on participants' clinical practices. Future efforts should focus on evaluating and quantifying this perceived positive impact, as well reproducing these efforts in other areas of need.

OBJECTIVE/UNASSIGNED:This systematic review aims to evaluate nasoalveolar molding (NAM) in the context of burden of care defined as physical, psychosocial, or financial burden on caregivers. SEARCH METHODS/UNASSIGNED:Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, 5 databases were searched from inception through December 24, 2019, for keywords and subject headings pertaining to cleft lip and/or palate and NAM. ELIGIBILITY CRITERIA/UNASSIGNED:Clinical studies on NAM with reference to physical (access to care, number of visits, distance traveled), psychosocial (caregiver perceptions, family interactions, breast milk feeding), and financial (direct and indirect costs) burden were included. DATA COLLECTION AND ANALYSIS/UNASSIGNED:Study selection was performed by 2 independent reviewers. RESULTS/UNASSIGNED:The search identified 1107 articles and 114 articles remained for qualitative synthesis. Burden of care domains were discussed but not measured in 43% of articles and only 25% assessed burden of care through a primary outcome. Of these, 20 articles reported on physical, 8 articles on psychosocial, and 12 articles on financial burden. Quality of evidence is limited by study design and risk of bias. CONCLUSION/UNASSIGNED:Nasoalveolar molding has been indiscriminately associated with burden of care in the literature. Although NAM may not be the ideal treatment option for all patients and families, the physical considerations are limited when accounting for the observed psychosocial advantages. Financial burden appears to be offset, but further research is required. Teams should directly assess the impact of this early intervention on the well-being of caregivers and advance strategies that improve access to care.

BACKGROUND:The authors present an institutional experience treating congenital and acquired temporomandibular joint (TMJ) ankylosis, detailing outcomes and potential risk factors of recurrence. METHODS:Retrospective chart review identified patients with TMJ ankylosis (1976-2019). Clinical records, operative reports, and imaging studies were reviewed for demographics, surgical operations, and ankylosis including maximal interincisal opening (MIO) and re-ankylosis. RESULTS:Forty-four TMJs with bony ankylosis were identified in 28 patients (mean age at any initial mandibular surgery: 3.7; range:0-14 years). Follow-up was 13.7 ± 5.9 years. Sixteen (57.1%) patients had bilateral ankylosis; 27(96.4%) had syndromes. Nine patients had congenital ankylosis, 16 had iatrogenic ankylosis (4.5 ± 3.7 years from initial distraction osteogenesis or autologous mandibular reconstruction) referred from outside institutions in 6 instances, and 3 had post-infectious ankylosis. Patients having their first mandibular operation at a younger age had more frequent reoperations for recurrent TMJ ankylosis, although this did not reach statistical significance. Mean improvement in MIO was 21.4 ± 7.3 mm. Ankylosis recurred in 21 (75%) patients. Five patients with congenital TMJ ankylosis required gastrostomy and remained at least partially dependent. Five patients had tracheostomy at the time of TMJ ankylosis surgery: 2 were eventually decannulated and 3 required repeat tracheostomy after ankylosis recurrence and remained tracheostomy-dependent. CONCLUSION/CONCLUSIONS:The clinical course of TMJ ankylosis in children affected by craniofacial differences is complex and typically involves a high rate of recurrence and multiple reoperations despite initial improvement in postoperative MIO. Younger age at initial mandibular surgery and number of operations require further investigation as potential predictors of recurrent TMJ ankylosis as well as tracheostomy and gastrostomy dependence.
