Synovial chondromatosis of the temporomandibular joint and its management

Abstract

Synovial chondromatosis is a condition in which loose fragments of cartilage develop in the synovial membrane of joints due to metaplasia of the subsynovial connective tissue. The resulting symptoms are similar to those of temporomandibular joint (TMJ) dysfunction. Clinical diagnosis can therefore be challenging. Synovial chondromatosis rarely occurs in the TMJ as its predilection is towards larger joints. A systematic review up until June 2010 reported a total 241 cases of TMJ synovial chondromatosis. We present two cases of TMJ synovial chondromatosis seen and treated in our department. CPD/Clinical Relevance: Awareness of TMJ synovial chondromatosis can enable patients to receive appropriate management before progression of the condition.
