Twenty-five temporomandibular joints (TMJs) in 15 patients with chronic arthritic disease were treated with synovectomy and diskectomy. Twenty patients with internal derangement of 27 TMJs treated with diskectomy served as a control group. A response in pain relief was seen in 73% of the patients with chronic arthritic disease and in 80% of the patients with internal derangement 3 yr postoperatively. In both groups of patients a significant increase in mouth opening capacity and lateral movement of the mandible was seen postoperatively, with no significant difference in the improvement between the two groups. Four patients with chronic arthritic disease were reoperated within the 3-yr observation period. This study indicates that synovectomy and diskectomy of the TMJ may reduce pain and improve mandibular function in patients with severe chronic arthritic TMJ disease.
对15例患有慢性关节炎疾病患者的25个颞下颌关节（TMJ）进行了滑膜切除术和盘状软骨切除术治疗。27个TMJ患有内紊乱的20例患者接受了盘状软骨切除术作为对照组。慢性关节炎疾病患者中73%和内紊乱患者中80%在术后3年出现疼痛缓解反应。两组患者术后张口能力和下颌侧方运动均显著增加，两组间改善情况无显著差异。4例慢性关节炎疾病患者在3年观察期内再次手术。本研究表明，TMJ滑膜切除术和盘状软骨切除术可减轻重度慢性关节炎性TMJ疾病患者的疼痛并改善下颌功能。
