Synovial condromatosis (SC) is a cartilaginous metaplasy of the mesenchymal remnants of the synovial tissue of the joints. It is characterized by the formation of cartilaginous nodules in the synovium and inside the articular space (loose bodies). SC mainly affects to big synovial joints such as the knee and the elbow, being uncommon the onset within the TMJ, where 75 cases have been published. The main symptoms are pain, inflammation, limitation of the movements of the jaw and crepitation. Different methods of diagnosis include panoramic radiograph, CT, MR and arthroscopy of the TMJ. We report a new case of unilateral SC of the TMJ, including diagnostic images, treatment performed and histological analysis.

Keywords : Synovial chondromatosis; temporomandibular joint; arthroscopy; sinovial metaplasy.
