摘要
目的 对比评价关节镜手术加或不加牙合垫治疗颞下颌关节盘不可复性前移位的效果。方法 一组(40例 )应用关节镜手术 (灌洗加松解术 )治疗关节盘不可复性前移位 ,另一组 (40例 )则在关节镜手术后配合牙合垫治疗。结果 随访 2年 ,术后 3个月时两组患者 (VAS法 )疼痛缓解程度均值分别为 1.8、2 .5 ,6个月时分别为 3.2、4 .8,1年时分别为 5 .6、5 .8,2年时分别为 6 .0、6 .2 ;张口度增加均值分别为 3个月时 5 .6mm、7.8mm ,6个月时为8.2mm、9.7mm ,1年时为 9.4mm、9.8mm ,2年时为 9.7mm、10 .2mm ,其中术后 3、6个月时疼痛及张口度改变均具有统计学意义 (P <0 .0 1) ,而 1年、2年时疼痛、张口度改变对比均不具显著性差异。结论 关节镜下行灌洗加松解术 ,并行牙合垫治疗关节盘不可复性前移位短期疗效 (3～ 6个月 )较单纯采用关节镜下行灌洗加松解术效果好 ,而术后 1～ 2年疗效差异不大。
Objective To evaluate the effect of two procedures on the treatment of anterior disc displacement without reduction (ADDWR) of TMJ. Methods 80 patients with ADDWR were classfied into two groups. One was treated by arthroscopic surgical lysis and lavage only, the other received additional splint therapy after the arthroscopic surgery. Results The mean pain relief degree of both groups was 1.8 and 2.5 respectively in three months (P>0.01) after the operation, 3.2 and 4.8 in six months (P<0.01), 5.6 and 5.8 in a year (P>0.01), 6.0 and 6.2 in two years (P>0.01). The mean mouth-opening degree was 5.6 and 7.8 mm respectively in three months (P>0.01) after the operation, 8.2 and 9.7 in six months (P<0.01), 9.4 and 9.8 in a year (P>0.01), 9.7 and 10.2 in two years (P<0.01). Conclusion In the treatment of ADDWR, arthroscopic surgery plus splint therapy is better than that without splint therapy in short term, but no different effect was found in the long term.
