Mandibular retrognathia: a review of the literature and selected cases.

Many techniques have been developed since the first osteotomy for correction of retrognathism was performed in 1905. These techniques have been in two groups--those that are performed in the mandibular body and those that are performed in the mandibular ramus. Ramus procedures are more favored because there is less morbidity in comparison to body procedures. Regardless of the procedure used, an adequate preoperative evaluation based on oral and radiographic examinations, study models, cephalometric analysis, and photographs is mandatory to achieve satisfactory results. A more satisfactory result can almost always be attained if a cooperative effort is made by the oral surgeon and orthodontist in the treatment of retrognathism.
