Radiographic Diagnosis of Osteochondritis Dissecans of the Temporomandibular Joint: Two Cases

Objective: To present two cases of osteochondritis dissecans (OCD) in temporomandibular joints (TMJs) evaluated by panoramic radiography and cone-beam computed tomography (CBCT). Clinical Presentation and Intervention: Two patients were referred to the Oral and Maxillofacial Radiology Clinic with pain, preauricular tenderness on the TMJ region and limitation of mandibular movements. An earlier panoramic radiograph revealed radiopaque lesions adjacent to the condyles. CBCT images were obtained from patients to assess the radiopacities. The CBCT scan detected irregular- type radiopaque lesions on anterior and superior aspects of the right condyle as well as degenerative osseous changes on both TMJs. Conclusion: The CBCT images revealed degenerative osseous changes and loose bodies on TMJs. The lesions were diagnosed as OCD with the help of trauma history, as well as clinical and radiographic findings.
