Synovial Chondromatosis of the Temporomandibular Joint Successfully Treated by Surgery.
Synovial chondromatosis (SC) is a chronic process, defined as a reactive cartilaginous proliferation, characterized by formation of cartilaginous nodules, usually loose in the joint space of the synovial membrane. It mainly affects large joints such as knee, hip, shoulder, and elbow, commonly in male patients. However, its manifestation in the Temporomandibular joint (TMJ), is a rare finding, occurring predominantly in females. This paper reports a case of a woman who presented to the service of Stomatology complaining of mouth opening limitations and pain in her left pre-auricular region. After clinical and radiographic analyses, the condition was diagnosed as SC of the TMJ. The loose bodies within the TMJ were removed under general anesthesia. Histological and follow-up features of this lesion are also discussed. To our knowledge, this is the second report of SC of the TMJ in Brazil.
