Surgical Management of Traumatic Temporomandibular Joint Ankylosis: A Case Report

Abstract

The complex disorder known as temporomandibular joint ankylosis (TMJ) affects nutrition and jaw function. Treatment options for post-traumatic joint ankylosis include a range of surgical methods. But no common procedure can ensure a successful outcome devoid of symptoms. Thus, treating TMJ injuries following trauma continues to be a difficult challenge for oral and maxillofacial surgeons. This paper is a case of a post-traumatic TMJ ankylosis. The 31-year-old young man sustained from many facial bone fractures, including condyles, in a car accident seven years ago. The condyle being treated conservative and the maxillary and malar fractures and mandibular parasymphysis was, treated with mini bone plates in other institution 7 years ago. After the surgery, he began to observe a gradually reduced mouth opening. (10mm) and further physiotherapy exercises was unable to restore normal mouth opening of the jaw. Preoperative CT revealed unilateral bony ankylosis on the right side of TMJ. Conservative treatments failed to restore normal jaw movement. An arthroplasty was carried out. The follow-up course went smoothly, with a mouth opening of up to 35 mm.
