Management of temporomandibular joint ankylosis with temporalis fascia flap and fat graft

Aim: Temporomandibular joint (TMJ) ankylosis is a serious problem that restricts jaw mobility and causes disturbances in facial and mandibular growth. The purpose of this paper is to present an easy and versatile method for the treatment of TMJ ankylosis to decrease postoperative complications such as re-ankylosis. Material and method: Eleven patients who presented with ankylosis of the TMJ underwent surgical release. After performing gap arthroplasty through a preauricular approach, the temporalis fascia flap was transposed to the gap. An autogenous fat graft was then obtained from the abdomen and used as interpositional material. The follow-up time was 3-5 years. Results: Re-ankylosis did not occur in any of the patients, and all had satisfactory mouth opening. Conclusion: Surgical treatment of TMJ ankylosis with gap arthroplasty, interposition of the temporalis fascia flap and fat grafting is an effective and easily procedure for preventing of re-ankylosis. The autogenous nature and close proximity to the joint are the main advantages of the temporalis fascia flap when compared with other interpositional materials, and the fat graft provides additional support by reducing pressure.© 2013 European Association for Cranio-Maxillo-Facial Surgery.
