目的为弥补关节镜滑膜下硬化疗法１周后瘢痕化的缺陷，使复位的关节盘即刻获得牵引固定。方法对３１侧颞下颌关节盘移位（可复性１５侧，不可复性１６侧）经关节镜确定移位的方向及程度，在关节盘复位操作及盘后区硬化疗法的基础上，采用后向和（或）侧向缝合牵引固定技术，术后即刻用关节镜评判盘复位情况。结果随访期２７个月（６～３９个月），总疗效７４２％（２３／３１），可复性盘移位疗效为９３３％（１４／１５）；不可复性为５６４％（９／１６）。结论本术式对关节盘移位，尤其是可复性移位的疗效优异；建议关节镜诊断、治疗及疗效评判同期进行
The purpose is to make up for scarification of arthroscopic sclerosis after 1 week, so that the reduction of the articular disc immediately get traction fixation. Methods 31 cases of temporomandibular joint disc displacement (refolding 15, non-reflexive 16 sides) by arthroscopy to determine the direction and degree of displacement in the face plate reduction operation and posterior disc area sclerotherapy based on the use of Posterior and / or lateral suture traction fixation, arthroscopy assessment of disk reduction immediately after surgery. Results The follow-up period was 27 months (range, 6 to 39 months) with a total effective rate of 742% (23/31). Retrograde plateau transposition effect was 933% (14/15) and no recanalization was 56 4% (9/16). Conclusions This procedure has excellent curative effect on disc displacement, especially reflexive displacement. It is suggested that arthroscopic diagnosis, treatment and curative effect evaluation should be performed concurrently
