title: Simultaneous chin onlay bone graft using elongated coronoid in the treatment of temporomandibular joint ankylosis.
abstract: Temporomandibular joint (TMJ) ankylosis is a disabling condition that causes problems in mastication, digestion, speech, appearance, and hygiene. Treatment goals are to restore the joint function, to improve facial appearance, and to reestablish harmony among them. To achieve these goals, various strategies have been reported as 1-stage or multistage protocols. We describe a novel method to augment the chin structure with elongated coronoid process of the mandible, which is a sequence of TMJ ankylosis. By this 1-stage treatment that includes gap arthroplasty with interpositional temporalis fascia graft and chin augmentation with autogenous bone graft (elongated coronoid), functional disability and facial deformity of the patient with TMJ ankylosis were improved simultaneously.
