Habitual temporomandibular joint (TMJ) luxation is a serious condition for the patient, and is often managed by extensive open joint surgery. Arthroscopic eminoplasty is an alternative, but this technique could also cause concomitant damage to the articular surface. The aim of this study was to evaluate the therapeutic effects and side effects of arthroscopic electrocautery of retrodiscal tissues in habitual TMJ luxation. All patients with habitual TMJ luxations who needed surgical management from 1 January 2000 to 31 December 2009 in the authors' institution in The Netherlands, were included in this study. All patients were primarily treated with arthroscopic electrocautery. Pre- and postoperative evaluation parameters were: TMJ luxations, maximum mouth opening, translatory capacity, pain and joint noises. Sixteen patients with habitual luxation were treated with arthroscopic electrocautery. Patient reluxation occurred in one. None of the patients had joint pain or mobility restrictions. The overall success rate was 95%. After 86 months there was a high success rate for this therapy. No other morbidity was seen, in contrast with open joint surgery or using sclerosing agents. The authors conclude that arthroscopic eletrocautery of retrodiscal tissues is a highly successful minimal invasive therapy in habitual TMJ luxation without side effects.
习惯性颞下颌关节（TMJ）脱位对患者来说是一种严重的情况，通常需要广泛的开放式关节手术治疗。关节镜下骺切除术是一种替代方法，但这种技术也可能会对关节表面造成伴随损伤。本研究旨在评估关节镜下关节盘后组织电灼术治疗习惯性 TMJ 脱位的疗效和副作用。所有因习惯性 TMJ 脱位需要手术治疗的患者，均纳入本研究。所有患者均首先接受关节镜下电灼术治疗。术前和术后评估参数包括：TMJ 脱位、最大张口度、移位能力、疼痛和关节噪音。16 例习惯性脱位患者接受了关节镜下电灼术治疗。1 例患者出现复发。所有患者均无关节疼痛或活动受限。总体成功率为 95%。经过 86 个月的治疗，该疗法具有很高的成功率。与开放式关节手术或使用硬化剂相比，没有出现其他并发症。作者得出结论，关节镜下关节盘后组织电灼术是一种治疗习惯性 TMJ 脱位的微创、成功率高、无副作用的方法。
