Long-term results of surgical intervention on the temporomandibular joint.
Between 1973-1987, 40 patients (51 joints) underwent 71 surgical procedures on the temporomandibular joint (TMJ). Indications for surgery included painful TM dysfunction, not alleviated by conservative treatment of at least 12 months' duration, or complete anterior disk dislocation not responding to conservative treatment for three to six months. The incidence of surgical treatment in the period 1983-1987 was 4.1% in a group of 679 patients. The mean follow-up is 5.8 years (range 1-15 years). At the follow-up examination (37/51) 72.5% of the treated joints appeared to have an excellent or good result; however, 14/51 joints had one or more reoperations (= 14/40 patients: 35%). The first surgical procedure on the TMJ resulted in an excellent or good result in 29/51 (57%) joints: 6/14 (= 42.9%) high condylectomies; 5/8 (= 62.5%) high condylectomies with a plication procedure; 15/24 (= 62.5%) plication procedure only; 2/2 silastic implants. After one or more reoperations, these figures improved to 10/14 (71%) high condylectomies, 7/8 (87.5%) high condylectomies with a plication procedure, 17/24 (70.8%) plication procedures. Radiographic changes, including flattening of the condyle, lack of condylar contour, erosion, sclerosis, subcondral cysts, and osteophytes were seen in all (16/16) patients in which a high condylectomy was performed. Out of 22 joints in which only a disk repositioning and plication procedure was performed, only 4/22 showed radiographic changes. The radiographic status was not correlated to the clinical picture at the time of the follow-up examination.
