Different surgical procedures in treating TMJ ankylosis

Procedure	Description
Gap arthroplasty [20]	This is the oldest surgical method and consists of resection of the bone only without any interpositional tissue or material.
Interpositional arthroplasty with autogenous grafts [7]	This involves gap arthroplasty and interpositional of autogenous tissues such as contochondrol grafts, temporalis muscle flaps, dermal grafts, auricular cartilage and fascia.
Interpositional arthroplasty with alloplastic materials [8, 21]	This involves the use of lyophilized dura mater or alloplastic materials such as vitalium, acylic, Teflon-proplast and silicone.
Placement of the hemijoint or total prosthesis [22]	Usually indicated for failed multioperated cases, example in advanced degenerative osteoarthritis or oncology cases.
