INTRODUCTION: Maxillary transverse deficiency (MTD) is a common facial disharmony that may need surgical assisted rapid palatal expansion (SARPE). The aim of this study was to present our SARPE technique and to report about our experience. MATERIEL AND METHOD: Medical records of all class III patients who underwent SARPE in our department from 2010 to 2015 and for whom a follow-up of at least 1 year was available, were included in a retrospective study. The technic consisted, after short orthodontic preparation allowing for divergence of the upper central incisors, in a complete Le Fort I osteotomy without down fracture, and medial sagittal submucosal separation of the hard palate under general anesthesia in an inpatient procedure...

Children with Prader-Willi Syndrome (PWS) may present with a malocclusion and have a high propensity of developing obstructive sleep apnea (OSA). Obstructive sleep apnea is associated with short- and long-term adverse effects that negatively impact children with PWS. A case of a 15-year-old male with PWS, OSA, and a debilitating malocclusion is presented who underwent a combination of Le Fort 1 osteotomy, genioplasty, and tongue reduction to successfully treat his OSA and malocclusion. In select cases, orthognathic correction and other surgical therapies should be considered in patients with PWS...
