Le Fort II midfacial distraction combined with orthognathic surgery in the treatment of Binder syndrome

Abstract

Abstract: PURPOSE: Patients with Binder syndrome have severe facial concavity and compromised skeletal Class III malocclusion. Its treatment is still challenging the surgeons. The aim of this study was to evaluate the effect of combined midfacial distraction and orthognathic surgery in the treatment of Binder syndrome. METHODS: Four patients with Binder syndrome were enrolled in this study. After modified Le Fort II osteotomy, the rotational distraction of nasomaxillary complex was performed to rehabilitate facial convexity. Then bilateral sagittal split ramus osteotomy (BSSRO) with or without Le Fort I osteotomy were used to correct malocclusion. RESULTS: All patients healed uneventfully and the maxillae moved forward conspicuously. No obvious pain and severe discomfort was complained during distraction. A significant advancement and downward movement of the maxilla was shown by cephalometric analysis. CONCLUSIONS: The combination of midfacial distraction and orthognathic surgery provided us an ideal alternative in the treatment of nasomaxillary hypoplasia.
