Efficacy of Interpositional Arthroplasty with Temporalis Myofascia Flap in Treatment of TMJ Ankylosis

Surgical intervention by resection of the ankylotic mass through gap arthroplasty alone resulted in reankylosis. Attempts have been made to prevent such reankylosis with interpositional arthroplasty. Numerous materials have been interposed between the resected bone surface and articular fossa at the base of the skull. Alloplastic materials such as silicone, silastic, proplast, Teflon, rubber prosthesis, metals, methyl methacrylate; and autogenous material such as full thickness skin, dermis, fascia, auricular cartilage, fat, Lyodura, costochondral graft, metatarsals, metacarpophalangeal joint transfer, sternoclavicular joint transfer and temporalis muscle and fascia have been used [5,6].
