ABSTRACT
Purpose: The purpose of this clinical study was to evaluate the functional restoration by interpositional arthroplasty with temporalis myofascial flap in temporomandibular joint ankylosis. Methods: After obtaining consent, the procedure were explained to the patient and each of the patients who met the inclusion criteria of the present study were randomly selected. Preoperatively all required investigations were done, fitness opinion for surgery and general anaesthesia was obtained, preoperative mouth opening / interincisal distance was measured with calliper, occlusion recorded, and midline shift was assessed. Surgical procedure (interpositional arthroplasty with temporalis myofascial flap) was carried out under general anaesthesia with endotracheal intubation. And patient was followed for about six months and following parameters were recorded. Mouth opening / interincisal distance, occlusion, Midline shift, Pain and Diet (solid/liquid). Results: In the present study, the temporalis myofascial flap was evaluated to be efficient in preventing the reankylosis. Preoperatively the mean interincisal opening was 6.93mm and post-operatively after a period of 6 months follow-up it remained as 34.93mm. Conclusion: The temporalis myofascial flap is an efficient interpositional material. It is a biologic, autogenous tissue, so there is no question of any rejection. The results of this study indicate that the use of temporalis muscle and fascia flap is effective in treating TMJ ankylosis.
