Anteriorly displaced temporomandibular joint articular disk. Report of a case diagnosed by computed tomography

The diagnosis of anterior displacement of a temporomandibular joint articular disk was made with computed tomography and documented with conventional arthrography. We are reporting the case to show the potential value of computed tomography for evaluating problems of the temporomandibular joint. The patient underwent thin-section axial computed tomography with advanced software imaging techniques. The articular disk was evident on the scan. It was anterior to the condyle and inferior to the articular eminence. Further studies are planned to determine whether computed tomography can supplement or possibly supplant conventional arthrography in the diagnosis of soft-tissue disorders of the temporomandibular joint.
