Application of neurolelectrophysiological monitoring in microvascular decompression of primary hemifacial spasm

Objective To explore the value of neuroelectrophysiological monitoring in microvascular decompression(MVD)of primary hemifacial spasm.Methods The data of 241 patients with primary hemifacial spasm underwent microvascular decompression were analyzed retrospectively.All patients underwent intraoperative neurophysiological monitoring,including abnormal muscle response(AMR),brainstem auditory evoked potential(BAEP)and free electromyography(Free-EMG).The results of electrophysiological monitoring,surgical efficacy and postoperative complications were analyzed.Results AMR disappeared in 218 cases and 210 cases were cured,2 recurred,4 had facial nerve dysfunction,19 with AMR were not disappeared,13 were cured,4 had recurrence and 3 had facial nerve dysfunction.The cure rate and recurrence rate of the two groups were significantly different(P<0.001),the results of facial paralysis were significantly different(P<0.001).There were changes in 16 cases about BAEP,including 4 cases of hearing loss and 11 cases of vertigo,225 of BAEP had no changes,no complications of hearing loss occurred but there was vertigo in 23.There were significant differences in hearing loss and vertigo incidence between the two groups(P<0.001).Conclusions Neuroelectrophysiological monitoring during MVD can predict the outcome and evaluate the prognosis.It has guiding significance and application value for surgery.
