PURPOSE: To report an exceptional case of bilateral synovial chondromatosis (SC) of the temporomandibular joint (TMJ) and discuss diagnostic approaches, treatment options and follow-up data.
PATIENTS AND METHODS: A 38-year-old woman presented with left preauricular swelling. Initial imaging studies revealed TMJ effusion only. Six years later, synovial calcifications were detected in the left TMJ; the right TMJ space was widened and presented incipient calcium deposits. Open arthrotomy of the left TMJ was performed, with removal of multiple cartilaginous loose bodies and complete synovectomy. Periodic controls proved the asynchronic development of intra-articular bodies in the right TMJ.
RESULTS: SC is a metaplastic arthropathy that is uncommon in the TMJ. Bilaterality is exceptional. Diagnosis is often delayed due to the non-specific symptoms, progressive developmental stages and clinicians' lack of awareness of the condition. Magnetic resonance imaging (MRI) is particularly helpful in defining disease extension, excluding a possible tumour and detecting internal derangement. Definitive diagnosis requires arthroscopic or open examination and histopathological analysis. Recurrences are infrequent after arthrotomy, removal of loose bodies and complete synovectomy.
CONCLUSION: SC is an uncommon condition in the TMJ. Bilateral involvement is extremely rare. MRI is effective for diagnosis and postoperative follow-up. Complete synovectomy usually yields an excellent prognosis.
