[A study on the newly designed platysma myocutaneous flap and its clinical applications]

From 1978 to 1991, the platysma myocutaneous flap of different designs was used to treat 69 patients with tumor extirpation defects of temporomandibular ankylosis. The conventional platysma myocutaneous flap was used to repair buccal defects. The combined platysma and sternocleidomastoid myocutaneous flap was used to reconstruct the tongue and the floor of the mouth. The innovated platysma myocutaneous flap, i.e. folded platysma myocutaneous flap was used to reconstruct the temporomandibular joint capsule for true ankylosis. All the procedure was completed in one stage and the operative results were satisfactory.
