Objective This study aimed to retrospectively analyze temporomandibular joint dislocation by surgical treat-ment and evaluate the treatment effect. Methods From May 2012 to April 2016, a total of 17 cases of temporomandibular joint dislocation were surgically treated, including 8 cases of irreducible dislocation (ID) and 9 cases of recurrent dislocation (RD). Synovial injection of sclerosing agent by arthroscope was performed in 5 cases, 9 sides; augmentation of the articular eminence by titanium plate implantation was performed in 7 cases, 12 sides; iliac bone transplantation was performed in 1 case, 1 side; Medpore implantation was performed in 3 cases, 6 sides; and eminectomy and capsular tightening were performed in 1 case, 2 sides. Follow-up was conducted 1–5 years after the operation, and the success rate statistics was obtained. Results The cure rate of synovial injection of sclerosing agent by arthroscope was 77.8％ (7/9), and the effective rate was 100％. The cure rate of titanium plate implantation was 75％ (9/12), and the effective rate was 100％. The cure rates of augmentation of the articular eminence by Medpore implantation (6/6), iliac bone graft (1/1), and eminectomy (2/2) were 100％. Conclusion The surgical method of temporomandibular joint dislocation was selected according to the state of the patients. The postope-rative recurrent patients were advised to undergo augmentation of the articular eminence by Medpore implantation, which offered a reduced chance of recurrence and relatively less injury, as well as a simple operative method.%目的?回顾分析颞下颌关节脱位的手术治疗病例,评价其治疗效果.方法? 选择2012年5月—2016年4月间收治的颞下颌关节脱位患者17例,包括陈旧性脱位(ID)8例和习惯性脱位(RD)9例.分别进行关节镜下滑膜下硬化剂注射术5例9侧,钛板植入关节结节增高术7例12侧,髂骨移植关节结节增高术1例1侧,Medpore植入关节结节增高术3例6侧,关节结节切除术1例2侧.术后1～5年随访,统计各手术方法的成功率.结果?关节镜下滑膜硬化术的治愈率为?77.8％(7/9),有效率100％;钛板植入关节结节增高术治愈率75％(9/12),有效率100％;Medpore植入关节结节增高术的治愈率为100％(6/6),髂骨移植关节结节增高术和关节结节切除术均治愈(1/1,2/2).结论?应根据病情轻重来选择术式,对手术后复发者可选用Medpore植入关节结节增高术,该术式疗效确切,创伤相对较小、操作较简单.
