[Radiological examination of the temporo-mandibular joint. Basic principles (author's transl)].

Radiological examination of the temporo-mandibular joint remains technically difficult. Standard views using usual X-ray techniques are inadequate. Preference must be given to selective tomography (sagittal, frontal or even axial) after determination of the axis of the condyles on a Hirtz position film. In certain cases, arthrography may also make it possible to define the contours of joint surfaces not seen on plain films. Radiocinematography is little used.
