[Computed tomography of anterior dislocation of the temporomandibular articular disk].
In a prospective study, the findings on arthrography and CT in 51 TMJs with anterior meniscus dislocation were compared. The CT diagnosis of anterior dislocation was made by a standardised method which we have developed and which depends upon evaluating axial sections. Sensitivity of the CT methods was 87%. In the absence of arthrography, a negative diagnosis in the asymptomatic contralateral side was made in 81%. Ruptures and adhesions could not be demonstrated by CT. For these reasons, arthrography is to be preferred to CT for making the initial diagnosis. CT should be carried out for special indications, such as contrast sensitivity, the documentation of a clinically confirmed diagnosis and for follow-up of treatment. Currently an attempt is being made to stage the disease by computed tomography.
