摘　　要：目的探讨面神经M波和F波对桥小脑角(CPA)区肿瘤病人面神经功能评估的临床意义。方法回顾性分析49例CPA区肿瘤病人的临床资料,均采用面神经电图检测M波和F波,统计比较健侧与病侧差异。结果与健侧比较,病侧M波波幅较低(P=0.023),F波潜伏期延长且波幅下降(P<0.001),F-M潜伏期延长(P=0.001)。结论F波、M波可以客观评价CPA区肿瘤病人的面神经功能,反映面神经近端的临床病变。Objective To explore the clinical significance of M wave and F wave in evaluating facial nerve function in patients with cerebellopontine angle(CPA)tumor.Methods Clinical data of 49 patients with CPA tumors were analyzed retrospectively.Facial nerve electromyography was used to detect the M wave and F wave in 49 patients.The data of healthy side and affected side were compared statistically.Results Compared with the healthy side,the M wave amplitude of the affected side was lower(P=0.023),the F wave latency longer and the F wave amplitude also lower(P<0.001).The F-M latency of the affected side was significantly longer than that of the healthy side(P=0.001).Conclusion F wave and M wave can objectively evaluate the facial nerve function in CPA tumor patients,and can reflect the clinical lesions of the proximal end of the facial nerve.
