This clinical study of 791 patients of temporomandibular joint ankylosis, included 623 interposition arthroplasty with temporal fascia, 48 dermal fat, 29 auricular cartilage, 12 acrylic joint replacement, 11 silicon, 24 costochondral graft, 23 sternoclavicular graft, and 21 chondro-osseous iliac graft. These patients were evaluated with regard to type of ankylosis, pre and postoperative mouth opening, and associated complications.
Complications like recurrence (4.80 % ), involvement of facial nerve (3.67 % ), anterior open bite (19.09 % ) and overgrowth of graft (0.5 % ) were observed in a follow up period ranging from 2 to 17 years.
Sternoclavicular graft reconstruction in children and dermal fat interposition arthroplasty in adults should be the treatment of choice for management of temporomandibular ankylosis.
