目的评判关节镜手术治疗复发性脱位患者远期疗效的稳定性。方法３０例患者的３４侧复发性脱位关节进行了３８例次关节镜手术（关节盘后区硬化疗法和关节盘缝合牵引固定术），其中４例次为重复关节镜手术，４例次为双侧同期手术。结果总疗效（随访期１个月～８年）：有效率９７％（３／３４）；治愈率８％（３０／３４）。其中，随访期２年以上的有２１例患者的２２侧受累关节，平均随访期４年（２～８年）。远期疗效：有效率９５％（２１／２２），治愈率８２％（１８／２２）。结论关节盘后区硬化疗法及关节盘牵引固定术对复发性颞下颌关节脱位有肯定的远期疗效
Objective To evaluate the long-term efficacy of arthroscopic surgery in patients with recurrent dislocation. Methods Thirty-eight patients with 34 recurrent dislocation joints underwent arthroscopic surgery in 38 patients undergoing joint arthroscopy (joint sclerotherapy and articular suture traction traction fixation), of which 4 were underwent repeat arthroscopic surgery and 4 were double Side surgery. Results The total efficacy (follow-up period of 1 month to 8 years): the effective rate was 97% (3/34); the cure rate was 8% (30/34). Among them, 21 patients with over 2 years of follow-up had 22 involved joints with an average follow-up of 4 years (range 2 to 8 years). Long-term efficacy: the efficiency of 95% (21/22), the cure rate was 82% (18/22). Conclusions The posterior posterior region sclerotherapy and disc traction fixation have definite long-term effects on recurrent temporomandibular joint dislocation
