摘要
目的:研究手术治疗颞下颌关节盘不可复性前移位的方法及近期疗效MRI评价。方法:对24例(30侧)Ⅲ-Ⅴ期颞下颌关节结构紊乱患者行改良切口关节盘锚固术。患者术前MRI诊断明确,术后1周进行MRI检查。选用斜矢状位内、中、外3个层面进行手术前后关节盘位置比较,评价手术疗效。结果:患者手术切口一期愈合,未发生永久性面瘫等并发症,手术后MRI显示,21例(26侧)关节为优;2例(3侧)关节为良;有效率达96.67%(29/30侧),术后最大张口度均值(32.17±2.30)mm,较之术前(23.63±3.31)mm有明显改善(P<0.05)。结论:改良切口锚固术治疗颞下颌关节盘前移位有近期疗效良好。
Objective： To evaluate the short-term effect of modified temporomandibular joint disc anchor for irreversible disc dis- placement of temporomandibular joint （TMJ）. Methods： A modified temporomandibular joint disc anchor surgery was performed for 24 patients with stage m - v TMJ internal derangement （ID） of 30 TMJs. Magnetic resonance imaging （MRI）were used to evaluate ID before and 1 week after operation for all patients. Results： All incisions heaied well and there was no severe complication. The postoperative MRI images showed that, the operation outcome of 26 joints （21 cases） was classified as excellent and 3 joints （2 ca- ses） was good. Maximal interincial opening increased from（23.63 -＋3.31 ） mm before operation to （32.17 ＋_2.30） mm 7 days after operation （P 〈 0.05 ）. Conclusion ： Modified temporomandibular joint disc anchor surgery may produce good short- term effects for the treatment of TMJ ID.
