Abstract：Objective To evaluate the clinic effects of electrophysiological monitoring during the microvascular decompression(MVD) for hemifacial spasm(HFS) .Methods From June 2012 to May 2014, 76 HFS patients were performed with intraoperative abnormal muscle reaction(AMR) and facial-motor evoked potentials(facial-MEP) during MVD. The therapeutic effect was evaluated at 1 week and 3 months postoperation. The relationship between AMR changes and prognosis, Facial-MEP and the postoperative early facial paralysis in monitoring period were analyzed.Results A single offending vascular was found in 60 patients and multiple offending vessels were found in 16 patients. Typical AMR(complete-disappeared, partial-disappeared, non-disappeared) was observed in all patients. Relief rate at 1 week and 3 months postoperation was 85.5%(65/76) and 92.1%(70/76), respectively. Relief rate in AMR-complete-disappeared group was higher than that of AMR-partial-disappeared group, but the correlation in the both group was not statistically significant(all P values＞0.05). The therapeutic effect in AMR-complete-disappeared group and AMR-partial-disappeared group were significanly better than that in AMR-non-disappeared group (all P values<0.05).Conclusions Intraoperative AMR monitoring is helpful in MVD surgery for HFS, which may improve the therapeutic effect.
