CASE REPORT

Background. The authors review the literature regarding osteocartilaginous loose bodies (that is, secondary synovial chondrometaplasia or secondary synovial chondromatosis) in the temporomandibular joint (TMJ), present a case report and stress the importance of early diagnosis.

Case Description. A 57-year-old woman was referred to an orthodontist with a chief complaint of bite changes that took place over several years as the patient intermittently experienced TMJ problems. The authors noted radiopacities around the right TMJ space on a panoramic radiograph. They referred the patient to an oral and maxillofacial surgeon for treatment.

Clinical Implications. Asymmetrical occlusal changes in a nongrowing adult with progressive shifts from Class I to Class III malocclusion unilaterally may indicate a space-occupying lesion in the TMJ space on the affected side.

Key Words: Temporomandibular joint; osteocartilaginous loose bodies; malocclusion; secondary synovial chondrometaplasia
