摘　　要：目的 :寻求有效的测试面神经临床神经电图的方法。方法 :通过对 114名正常人及 6 9名创伤性面神经损伤患者神经电图测试 ,比较耳前、耳后刺激各项测试结果 ,并进行统计学分析。结果 :耳后刺激各测定值较耳前更有效。结论 :面神经电图临床测定中 ,刺激方式应首选耳后刺激。砄bjective: To explore an effective method for Electroneurography(ENoG) of facial nerve. Methods: ENoG of 114 normal subjets and 69 patients with traumatic facial nerve injuries were investigated. Latency time(LT), duration time(DT), amplitude(A) and square under the curve(S) were measured in facial muscles when facial nerve was stimulated postauricularly or anteroauricularly. Results: In most facial musles except square muscle of lower lip postauricular stimulation gave longer LT, shorter DT, lower A and smaller S. Conclusion: The postauricular stimulation is effective prior to anteroauricular stimulation for electroneurography of the facial nerve.
