[Contribution of air computerized tomography of the joint in the assessment of algo-dysfunctional syndromes of the mastication system].

The prospective study of evaluation temporomandibular dysfunction by air computerized tomography of the joint are reported. The authors propose a new injection technique of both articular compartments by CT Scan location. With thin sagittal computed tomography sections, closed mouth and open mouth position, this study is made. Preliminary data from air computerized tomography of the joint imaging show directly the disk with anterior and posterior attachments. The authors present the normal results and major pathology found in the evaluationof temporomandibular dysfunction. CT Scan puncture is more precise. The air computerized tomography imaging of the joint was undoubtedly superior to that of conventional opaque joint tomography, but dynamic notion is much less than in the absence of videoscopy.
