“…Common dentofacial deformities include prognathism and retrognathism that can range in severity. 4,5 Maxillomandibular advancement offers multilevel expansion of the airway and is particularly helpful in patients with skeletal abnormalities contributing to obstructive sleep apnea with high rates of clinical success. 2,3,6 Classically, orthognathic surgery has been performed in conjunction with orthodontic treatment.…”

“…18 In cases with severe class II occlusion, retrognathia, diminutive condyles, and decreased lower posterior face height, it will be necessary to lengthen the ramus, which is difficult to perform using the bilateral sagittal split ramus osteotomy technique. 5 Another osteotomy that can be utilized in this situation is the inverted L osteotomy. This technique can be performed using a transoral or transcutaneous approach.…”

Orthognathic surgery performed in conjunction with orthodontic treatment is commonly performed to correct skeletal irregularities and realign the maxillomandibular relationship to improve occlusal function and facial esthetics. A thorough understanding of soft tissue esthetics, skeletal and occlusal relationships, and surgical techniques is required to obtain successful results. Surgical techniques have evolved greatly throughout history, as technological advances such as virtual surgical planning have become available and widely used to obtain predictable movements with minimized complications. The aim of this article is to review the orthognathic surgical procedures of the mandible, with particular attention to the indications, contraindications, preoperative assessment, surgical technique, and possible complications encountered.
