There are many treatments described for closed lock of the temporomandibular joint. Eminectomy has been described in the treatment of recurrent dislocation of the jaw. The use of a 'true' eminectomy alone, as the treatment of closed lock has not been previously described. Eighteen patients, three male and 15 female, with a mean age of 28 years, underwent 22 eminectomy procedures. The mean follow-up period was 7 months, assessment was both subjective, using a retrospective Visual Analogue Scale (VAS), and objective with measurement of the Inter Incisal Distance (IID). Overall the subjective improvement in symptoms was high with a score of 85.5 on a 100 mm VAS. The mean improvement in Inter Incisal Distance, was 17.9 mm a statistically significant result using a paired t test (p < 0.001).
颞下颌关节闭锁有多种治疗方法。乙状切迹切除术已被用于治疗复发性下颌脱位。单独使用“真正的”乙状切迹切除术治疗颞下颌关节闭锁此前尚未见报道。18例患者，男性3例，女性15例，平均年龄28岁，接受了22次乙状切迹切除手术。平均随访期为7个月，评估采用回顾性视觉模拟量表（VAS）进行主观评估，并通过测量切牙间距离（IID）进行客观评估。总体而言，症状的主观改善程度较高，在100毫米视觉模拟量表上得分为85.5分。切牙间距离的平均改善为17.9毫米，采用配对t检验得出具有统计学意义的结果（p<0.001）。
