Inverted L-shaped ramus osteotomy for prolonged bilateral dislocation of the temporomandibular joint

The various methods of management of prolonged bilateral anterior dislocation of the temporomandibular joints are discussed and the literature is reviewed. Reported is a case in which a bilateral inverted L-shaped ramus osteotomy was performed in order to reposition the mandible and establish normal occlusion; the results were satisfactorily maintained one year postoperatively.
