Tratamento de anquilose da articulação temporomandibular. Relato de um caso

Abstract

Temporomandibular Joint Ankylosis (TMJA) is a disorder that is related to a fibrous adhesion or bony fusion between the anatomical components of the joint such as the condyle, articular disk, glenoid fossa and articular eminence. This condition promotes a restriction of mandibular movements. The treatment goal is to reestablish the joint movements, avoid recurrences prevention, and to restore the appearance achieving the desired occlusion. Many techniques for TMJA treatment have been described in the literature, but no technique has proved entirely successful. Gaps arthroplasty with interposicional graft has become an acceptable standard as primary surgical treatment. Interposicional materials have been used such as: TMJ disc, temporalis muscle, temporal fascia, skin, ear cartilage, fat, alloplastic materials and xenogenous grafts. This paper describes a case report of a 26 year-old male patient, which was diagnosed with TMJA after infection of dental origin. The performed treatment was interposicional arthroplasty with temporalis fascia and muscle graft as interpositional material. Eight months after surgery, the patient presented interincisal maximum opening of 37 mm and no signs of relapse.
