Computed tomography of the meniscus of the temporomandibular joint: preliminary observations.

Abstract

Anterior displacement of the meniscus of the temporomandibular joint (TMJ) was diagnosed in 9 patients who had undergone arthrography, and they were later examined with computed tomography (CT) to see if this modality could supplant arthrography in some patients with TMJ dysfunction. The anteriorly displaced menisci were visualized in all 9 patients by using sagittal reformations and the blink mode. Of the 9 patients, 4 had the diagnosis confirmed at surgery. The precise protocol for the CT examination and how to interpret it are discussed. CT may replace TMJ arthrography in selected patients.
