We would like to introduce the technique of arthrography used at the upper and lower compartments of TMJ in our Department. Typical cases were represented and some discussious were made.
(1) The number of patients suspected to suffer from internal derangements of TMJ and accepted arthrography was 33 cases (37 joints). The results were as follows: 7 normal type joints, 11 clicking type joints (6 early clicking type joints and 5 late clicking type joints), 15 closed lock type joints, and 2 incoordination type. The arthrographic findings of 4 joints were different from the clinical diagnosis. Represented separately were closed lock type 3 joints, late clicking type 1 joints.
(2) Complications as morphological disorder of TMJ's soft tissue were seen in all the joints with internal derangements as follows: 29 joints bad thickening or elongation of the disk, 4 joints folding of the disk, 3 joints perforation of the disk, 9 jointsadhesion of the disk (6 adhesion of the upper compartments, 1 adhesion of the lower compartments, and 3 adhesion of upper and lower compartments).
(3) In almost all the cases after arthrography, the secondary complications were seen as follows: Incomplete occlusion of arthrogramed side, temporary paralysis of facial nerve, motor pain of arthrogramed side. Three cases of closed lock were discovered.
