Clinical Effect of MVD in Patients with Hemifacial Spasm Under Neuroelectrophysiological Monitoring and the Influence of Complications
Objective:To explore the effect of MVD on the clinical treatment and complications of patients with hemifacial spasm under neuroelectrophysiological monitoring.Methods:78 patients with hemifacial spasm admitted to the hospital from May 2016 to June 2021 were selected as the study objects,and they were randomly divided into control group(39 cases)and monitoring group(39 cases).All patients in the 2 groups were treated with MVD,and neuroelectrophysiological monitoring was performed in the monitoring group during MVD.The lateral diffusion response(LSR)of facial nerve and the V-wave in brainstem auditory evoked potential(BAEP)of the monitoring group were observed,and the postoperative clinical treatment effect and postoperative complications of the two groups were compared.Results:Through neuroelectrophysiological monitoring during MVD operation in the monitoring group,it was found that LSR waveform disappeared during cerebellar pontine Angle detection in 5 patients,disappeared during nerve decompression in 32 patients,and LSR waveform remained visible in the remaining 2 patients until the end of MVD operation.The total effective rate of the monitoring group 1 day after surgery was higher than that of the control group(P＜0.05).Total complication rate in the monitoring group was lower than that in the control group(χ2=22.675,P＜0.05).Conclusion:Patients with hemifacial spasm were treated with MVD under neuroelectrophysiological monitoring,and the clinical therapeutic effect is more significant.At the same time,the occurrence of complications in patients with hemifacial spasm is less,which was more advantageous than the clinical treatment of patients with hemifacial spasm by MVD alone,which is worthy of clinical reference.
