[Computerized tomography of sagittal sections. A noninvasive alternative in the exploration of temporomandibular joint dysfunction].

Important advances in the use of CT scan imaging for exploration of the temporomandibular joint include the obtaining of direct sagittal section images and the possibility of surveillance. This avoids the need for more invasive and painful techniques such as arthrography. The position of the meniscus can be determined from either direct or indirect signs and bone structures and muscles are particularly clearly demonstrated. This technique can be used while awaiting more widespread availability of NMR apparatuses for meniscal exploration.
