Objective: Microvascular decompression (MVD) of the facial nerve is an effective treatment for hemifacial spasm (HFS). The authors investigated that the results of 190 microvascular decompression (MVD) procedures for hemifacial spasm. Methods: The follow up period ranged from 6 months to 3 years. Of these, 68.4% (130 cases) were women (mean age 55). The vessel most frequently found to compress the facial nerve was the anterior inferior cerebellar artery(40%) followed by posterior inferior cerebellar artery(30%). Results: For 190 cases, 148 patients(77.9%) had complete relief of spasm within 3 days after MVD, 31 patients(16.3%) subsequently experienced complete relief, noted in 4 days to 6 months after MVD, ten patients had delayed partial relief and remaining one patient showed no improvement. There were 9 cases of operation-related complications, including one case of ipsilateral hearing loss. Conclusion: These results suggest that MVD is a high success rate and satisfactory treatment for hemifacial spasm.
