M636: Orthognathic Surgery: Treatment Planning and Surgical Techniques

Abstract

Surgical techniques in orthognathic surgery have and will continue to undergo modifications and change in an effort to improve the quality of patient care and outcome. This program will present state–of–the–art surgical techniques and research results substantiating the efficacy of these surgical methods. The following modifications will be discussed:1. Genioplasty A. Augmentation B. Tenon and mortise osseous genioplasty2. Anterior mandibular subapical osteotomy3. Mandibular body osteotomy4. Mandibular ramus sagittal split osteotomy modifications A. Ramus and inferior border osteotomy B. Rigid fixation5. Maxillary osteotomy modification A. Maxillary step osteotomy and rigid fixation B. Porous block HA grafting6. Double jaw surgery A. Selective alteration of the occlusal plane B. Surgical sequencing of the maxilla and mandible C. Model surgery modifications7. TMJ factors affecting orthognathic surgery outcomesImplementation of these techniques by the experienced, skilled surgeon, coupled with accurate diagnosis and treatment planning, should provide optimal functional and esthetic outcomes for our patients.
