A retrospective study on 14 patients with TMJ internal derangements who had undergone a disk plication surgery, was performed for assessing the surgical results and postoperative radiograhic changes of the mandibular condyle. Regarding the surgical results, 10 of the 14 patients were evaluated as “excellent”, 3 patients were as “better”, and the remaining 1 patient was assesed as “poor”, in an average of 40 months follow-up period. Postoperative radiographic changes were evaluated on 11 joints in a mean follow-up period of 30 months; 1 of 11 joints was disclosed as having no significant change, and each 5 joints were revealed as having mild and moderate changes respectively. There was no severe surgical complication. These results suggested that the disk plication surgery for internal derangement of the TMJ is an appropriate procedure.
