[摘要] 目的探讨术前磁共振影像学特征对面肌痉挛显微微血管减压术难易度评估的价值。方法观察2012年4月至2012年9月手术治疗105例原发性面肌痉挛患者的核磁共振检查结果,统计并分析责任血管的大小、小脑凸起高度、后颅窝形态以及蛛网膜下腔形态对显微手术操作时间长短的影响关系。结果责任血管的大小和后颅窝形态对手术的难易程度产生显著的影响,其余因素可能会影响手术的难易度。结论术前磁共振影像学特征对初步判断面肌痉挛显微微血管减压术的难易程度有重要的价值。

[Abstract] Objective To investigate the features of MRI scan and the value of these features for judging the difficulty level of microvascular pression surgery. Methods MRI results of 105 primary hemifacial spasm patients were observed prior to MVD. Mesured the size of the responsible vessel, the convexity extent of cerebellum, the posterior cranial fossa morphology and also the subarachoid space morphology, then analyzed their effect on operation time. Results The size of the responsible vessel and the posterior cranial fossa morphology had an obvious effect on the difficulty level of MVD, and the other factors probably did. Conclusion Pre-operative MRI features is significant to judge the the difficulty level of microvascu
