Comparative Study of Maxillary Growth in Patients With Unilateral Cleft Treated With and Without Pre-Surgical Orthopedics.

Compare the maxillary growth of patients with Unilateral Cleft treated with pre-surgical Functional Maxillary Orthopedic (FMO) and that of who underwent a surgical procedure with no previous use of appliances.Prospective study, the patients were divided into 2 groups. G1, was composed of 12 patients who received no pre-surgical intervention and cheilorhinoplasty at 6 months of age and G2, included 12 patients treated using Pre-Surgical Funtional Maxilary Orthopedic; they underwent no surgery during the study. Measurements were taken at three times: before the first month of life, at 6 months and between 9-12 months of age. Cleft distance (anterior, medium and posterior), maxillary width (anterior, medium and posterior) and minor and major segment width were analyzed.Alveolar Cleft decrease was 79.82% in G1 and 52% in G2. Posterior Cleft decrease was 24.1% in G1 and 41.77% in G2. Greater Segment Width increase was 24.53% for the patients in G1, and 37.47% for the patients in G2. As for Inter Canine Width, a decrease of 5.16% in G1 and an increase of 9.19% in G2 were found. Medium Arch Width only increased in a statistically significant manner in G2 9.02%.Surgery allowed for the closure of the alveolar cleft. FMO made it possible to close the anterior and the posterior clefts through the growth of the maxillary segments, increased the transverse growth of the maxilla and could prevent maxillary collapse. Each team must individually evaluate whether to indicate or not the use of preoperative orthopedics.

Disability Caused by Cleft Lip and Palate: A Systematic Review and Critical Valuation Appraisal.

OBJECTIVE: Measuring disability as a concept of impaired global function enables beneficiaries of treatment, the impact of treatment, and targets of health system investment to be rigorously assessed. Measures of disability are not well established for cleft lip and palate. This study aims to systematically review disability weight (DW) studies pertaining to orofacial clefts (OFCs) and identify methodological strengths and shortcomings of each approach. DESIGN: Systematic literature review of studies that met the following criteria: (1) peer-reviewed publication, (2) focus on disability valuation, (3) mention orofacial clefts, and (4) publication January 2001-December 2021. SETTING: None. PATIENTS/PARTICIPANTS: None. INTERVENTIONS: None. MAIN OUTCOME MEASURE(S): Disability weight method of valuation and the value itself. RESULTS: The final search strategy yielded 1,067 studies. Seven manuscripts were ultimately included for data extraction. The disability weights used in our studies, including those newly generated or taken from the Global Burden of Disease Studies (GBD), ranged widely for isolated cleft lip (0.0-0.100) and cleft palate with or without cleft lip (0.0-0.269). The GBD studies limited their consideration of cleft sequelae informing disability weights to impact on appearance and speech-related concerns, while other studies accounted for comorbidities such as pain and social stigma. CONCLUSIONS: Current measures of cleft disability are sparse, inadequately reflect the comprehensive impact of an OFC on function and socialization, and are limited in detail or supporting evidence. Use of a comprehensive health state description in evaluating disability weights offers a realistic means of accurately representing the diverse sequelae of an OFC.

Surgical Repositioning of the Premaxilla Using a Minimally Invasive Endonasal Approach.

OBJECTIVE: The aim of this study was to evaluate a technique for the surgical repositioning of the premaxilla using a minimally invasive endonasal approach. DESIGN: Retrospective review of clinical records. SETTING: Tertiary care, University Hospital, pediatric maxillofacial surgery unit. PATIENTS: Twenty-one patients (12 boys and 9 girls), ages ranging from 6 to 21 years, with BCLP+A and premaxillary malposition (PM). INTERVENTIONS: Surgical repositioning of the premaxilla (SRP) using a minimally invasive endonasal approach, from November 2007 to November 2015. MAIN OUTCOME MEASURES: Achieving maxillary arch alignment and premaxillary stability was defined as treatment success. Intraoperative and postoperative complications were also recorded. RESULTS: In all cases (100%), the treatment was successful either at first surgery or after reoperation. Two patients (9.5%) were reoperated-one due to premaxillary instability and one due to PM relapse. There were no perioperative complications. CONCLUSIONS: SRP using a minimally invasive endonasal approach is a safe and effective technique that levels and aligns the maxillary arch in preparation for SABG, which minimizes the risk of wound infection and premaxillary vascular compromise. The endonasal approach improves tissue quality of the mucoperiosteal flaps when performing the SABG procedure. Further prospective studies are needed to elucidate the best protocols and techniques for the management of PM in patients with BCLP+ A.

Bone Allograft Segment Covered with a Vascularized Fibular Periosteal Flap: A New Technique for Pediatric Mandibular Reconstruction.

The free vascularized fibular graft is nowadays the preferred technique for pediatric mandibular reconstruction. Despite the versatility and proven efficacy for restoring the facial appearance and maxillomandibular function, those mandibular reconstructions with free vascularized fibula associate difficulties for a simultaneous restoration of the alveolar height and facial contour, which are derived from the height discrepancy between the fibula and the native mandible. In addition, the donor-site growth and morbidity are of special concern in the pediatric patient. We report a novel technique for pediatric mandibular reconstruction, in an 11-year-old girl, using a combination of a bone allograft segment with a vascularized fibular periosteal flap (VFPF), after resection of an Ewing sarcoma located at the right body of the mandible. The patient has showed optimal cosmetic, functional, and radiological outcomes, which have been maintained for 2.5 years, without detecting donor-site complications. Through this original technique, and based on the powerful osteogenic and vasculogenic properties of the pediatric VFPFs, we could effectively reconstruct a large mandibular defect providing a functional and aesthetic reconstruction, while avoiding the potential morbidity associated with the fibula resection.
