摘　　要：目的：探讨磁共振成像对特发性面肌痉挛的诊断价值。方法回顾性分析68例经手术治疗的特发性面肌痉挛病例临床表现,磁共振表现及手术所见,比较面肌痉挛患者与正常对照组血管面神经关系；比较面肌痉挛患者与正常对照组血管神经接触部位；比较面肌痉挛患者与无症状人群椎基底动脉走行情况；总结具有诊断意义的磁共振征象。结果68例患者经磁共振检查诊断符合率达到94.1%~96.9%；面肌痉挛患者与正常对照组血管面神经关系具有明显差异（χ2=42.16,P=0.001＜0.05）；血管压迫面神经根部（REZ区）是面肌痉挛发作的主要原因,与脑池段接触者多无症状（χ2=69.873,P=0.000＜0.05）；面肌痉挛患者与无症状人群比较椎动脉走行有所不同（χ2=35.077,P=0.001＆lt;0.05）。结论磁共振面神经检查对诊断面肌痉挛,决定治疗方案,进行术前评估具有重要的价值。Objective To explore the diagnostic value of MRI for idiopathic facial spasm.Methods Collected 68 cases of patients with vascular conflicted facial spasm after surgical treatment,analyzed the clinical manifestation,MRI manifestations and surgery retrospectively.Compare the situation of vascular compression in patient against healthy person;the location of vascular compression in patient against healthy;comparing the courses of vertebral artery in facial spasm patients with asymptomatic people,etc.Summarizes the diagnostic significance of MRI signs.Results MRI diagnosis coincidence rate was 94.1%-96.9%;The vascular compression situation were obvious differences between patient and healthy （χ2= 42.16,P=0.001〈0.05）;Artery oppress facial nerve roots （REZ area）was the main reason for the case.There is usually no symptoms with the oppression in cistern part of facial nerve （χ2=69.873,P=0.000〈0.05）;The verte-bral artery localized different between facial nerve patients and healthy （χ2=35.077,P=0.001＆lt;0.05）.Conclusion The facial nerve examination of MRI is useful for diagnosing idiopathic facial spasm,decide therapeutic schedule,evaluation before operation.
