Abstract: Objective To investigate the efficacy of microvascular decompression in the treatment of hemifacial spasm. Methods The clinical data of 48 patients with hemifacial spasm treated in department of neurosurgery during Feb. 2014 and Sep. 2018 were retrospectively analyzed, including the effective rate, complication rate, treatment plan and prognosis. The patients were divided into two groups: immediate cure group and delayed cure group. The length of medical history, gender, age, severity of symptoms, and number of responsible vessels were compared between the two groups. Results All patients were followed up, and no death occurred. Of all patients, 35 cases(72.92%)were immediately cured, 12 cases(25.00%)had delayed recovery, and 1 case(2.08%)was not responsive. No case deteriorated. The overall effective rate was 97.92%. Analysis of the influencing factors of delayed cure showed that there were no significant differences in gender, age, severity of symptoms, and number of responsible vessels between the two groups(P>0.05), while there was significant difference in medical history. Complications included headache in 17 cases(35.42%), dizziness and nausea in 27 cases(56.25%), leakage of cerebrospinal fluid in 2 cases(4.17%), fever in 7 cases(14.58%), facial paralysis in 12 cases(25.00%), and hearing loss in 7 cases(14.58%). All complications were cured except for 1 case with facial paralysis and hearing loss. Conclusion Microvascular decompression is effective in the treatment of hemifacial spasm. Longer length of medical history is associated with delayed cure.

Key words: Hemifacial spasm, Microvascular decompression, Electrophysiological monitoring, Responsible vessel, Delayed cure
