Uzun Süreli Temporomandibular Eklem Dislokasyonunun Çift Taraflı Eminektomi ve Chin-Cap ile Tedavisi

Abstract

Temporomandibular joint (TMJ) dislocation is defined as an excessive forward movement of the condyle beyond the articular eminence resulting in a condition that fixes the joint in the open position, preventing any translation. Acute dislocation of the TMJ may be reduced manually under local anesthesia, intravenous sedation or general anesthesia. However, chronic persistent or prolonged dislocations usually require surgical intervention. Various surgical interventions have been proposed for the management of prolonged dislocation. Some of these are more conservative, such as reduction with the aid of interosseous wire, modified intermaxillary fixation, eminectomy and myotomy, while others are more radical such as condylectomy, midline mandibulotomy, inverted L-shaped ramus osteotomy or sagittal split ramus osteotomy. This case report describes the clinical and radiological findings and comprehensive treatments with bilateral eminectomy and chin-cap support of a patient with long-term and prolonged bilateral TMJ dislocation resulting from misdiagnosis.
