Double-contrast tomography of the temporomandibular joint. A new technique based on autopsy specimen examinations.

Double-contrast tomography was applied to temporomandibular joint autopsy specimens. Both joint compartments were given successive injections of air-iodine contrast medium-air. Tomography was performed in lateral and a.p. projections using a multi-film cassette. The shape of the disc and joint compartments was well demonstrated. The influence of the tomographic level and the position of the condyle on the appearance of the disc was analysed.
