Maxillary orthognathic surgery

Abstract

Maxillary surgery to correct dentofacial deformity has been practiced for almost 100 years. Significant advances have made maxillary surgery a safe and efficient means of correcting midface deformities. Anesthetic techniques, specifically hypotensive anesthesia, have allowed for safer working conditions. Landmark studies have proven manipulation and segmentalization of the maxilla is safe and allowed this surgery to become a mainstay in corrective jaw surgery. This article provides an overview of surgical techniques and considerations as they pertain to maxillary surgery for orthognathic surgery. Segmental surgery, openbite closure, vertical excess, grafting, and a technology update are discussed.
