Extensive synovial osteochondromatosis of the temporomandibular joint: An open approach

Abstract

A patient with extensive unilateral synovial chondromatosis (SC) presented with common temporomandibular joint (TMJ) symptoms of pain, cracking noises, locking and limited range of opening. Plain radiographs and computed tomography (CT) imaging revealed numerous dense bodies surrounding the TMJ with one larger multilobular mass medial to the joint. Imaging was diagnostic of SC and the patient underwent synovectomy and removal of the tumours.
