Orthognathic Surgery and Rhinoplasty to Address Nasomaxillary Hypoplasia.

The treatment of nasomaxillary hypoplasia is challenging. The phenotype of Binder "syndrome" includes the following: midfacial hypoplasia, class III malocclusion, small or absent anterior nasal spine, flattened nose, horizontal nostrils, short columella, acute nasolabial angle, and a flat frontonasal angle. A staged approach is used, with orthognathic surgery to achieve vertical maxillary length and sagittal advancement, followed by rhinoplasty aimed to increase nasal tip projection, rotation, and columellar length. This article details the diagnosis and treatment of nasomaxillary hypoplasia, demonstrating the senior author's (D.M.S.) preferred approach and technical steps.
