Early diagnosis and treatment are crucial if the worst sequelae of this condition are to be avoided. Surgery of TMJ ankylosis needs careful evaluation and planning to yield predictable results. Ankylosis may be corrected surgically by an array of procedures like gap arthroplasty, joint reconstruction and interpositional arthroplasty.Key words: Gap, Artroplasty, Temporomandibular, Ankylosi
