Orthognatic Surgery:: 1. Slide 1 Definition

Orthognatic surgery refers to surgical procedures used to correct dentofacial deformities. It involves a cephalometric analysis to evaluate facial proportions and dental examination to determine the type of malocclusion. For the case presented, there was a Class III deep bite malocclusion that was treated with bilateral sagittal split ramal osteotomy and partial glossectomy. There was also facial asymmetry of the lower and middle face, maxillary rotation, right condylar hyperplasia, and dental/facial midline deviation, which were addressed through Le fort I osteotomy, bilateral sagittal split ramal osteotomy, and condylectomy. Maxillary deficiency was characterized by a short vertical face
