Two-stage total prosthetic reconstruction of temporomandibular joint in severe and recurrent ankylosis.

Temporomandibular joint ankylosis is a devastating condition for the patient associated with both functional disability and aesthetic deformities. Various techniques have been described in the literature to overcome this problem; however, there is still a high risk of reankylosis in patients undergoing multiple temporomandibular joint operations, severe heterotopic ossification, and fibrosis of the soft tissues. This study includes 5 patients with severe and recurrent ankylosis. Two-stage reconstruction with excision of the bony mass and placement of a distraction device in the first stage, followed by gradual distraction of soft tissues, and placement of a total joint prosthesis in the second stage were performed in all patients. The 2-step approach helps to overcome the fibrosis and adhesions in the soft tissues and allows placing an implant with a higher ramus component. This approach seems to be a useful and effective technique for the management of such patients with high risk of reankylosis.
