Synovial chondromatosis (SC) of the temporomandibular joint (TMJ) is a rare disease characterized by the presence of calcified loose bodies within the joint, and few systematically gathered data are available about its epidemiology. The aim of this paper was to describe a case of SC of the TMJ, and to carry out a systematic review of the literature on epidemiology over the past decade. A case of a 53-year-old female with the classical triad of signs and symptoms of SC (pain, swelling, restricted mouth opening) is described. A systematic search in the National Library of Medicine's PubMed Database was performed. 155 cases were described in 103 publications. Most dealt with single case reports. Females are affected more than males with a 2.5:1 ratio and the mean age of patients was about 46 years. Late diagnosis is common and in most cases more than 2 years elapsed between symptom onset and surgical intervention. Open TMJ surgery is the treatment of choice, since less invasive techniques, such as arthroscopy, allowed complete removal of the loose bodies only in about half of cases. A single recurrence was described, confirming the benign nature of the disease. Copyright 2010 International Association of Oral and Maxillofacial Surgeons. Published by Elsevier Ltd.

Abstract
Synovial chondromatosis (SC) of the temporomandibular joint (TMJ) is a rare disease characterized by the presence of calcified loose bodies within the joint, and few systematically gathered data are available about its epidemiology. The aim of this paper was to describe a case of SC of the TMJ, and to carry out a systematic review of the literature on epidemiology over the past decade. A case of a 53-year-old female with the classical triad of signs and symptoms of SC (pain, swelling, restricted mouth opening) is described. A systematic search in the National Library of Medicine's PubMed Database was performed. 155 cases were described in 103 publications. Most dealt with single case reports. Females are affected more than males with a 2.5:1 ratio and the mean age of patients was about 46 years. Late diagnosis is common and in most cases more than 2 years elapsed between symptom onset and surgical intervention. Open TMJ surgery is the treatment of choice, since less invasive techniques, such as arthroscopy, allowed complete removal of the loose bodies only in about half of cases. A single recurrence was described, confirming the benign nature of the disease. Copyright 2010 International Association of Oral and Maxillofacial Surgeons. Published by Elsevier Ltd.
