Computed tomography of the meniscus of the temporomandibular joint: preliminary observations.
Anterior displacement of the meniscus of the temporomandibular joint (TMJ) was diagnosed in nine 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 nine patients by using sagittal reformations and the blink mode. Four of the nine patients had the diagnosis confirmed at surgery. The precise protocol for the CT examination and how to interpret it are discussed. We are optimistic that CT may replace TMJ arthrography in selected patients.
