Abstract Background Microvascular decompression (MVD) is the most useful treatment for hemifacial spasm (HFS). In cases of vertebral artery (VA) compression of the facial nerve, MVD is often difficult. In this study, we compared the outcome of the biomedical glue sling technique with the traditional technique in MVD for HFS involving the VA. Methods This was a retrospective study of patients with HFS treated by MVD, and was conducted between January 2013 and December 2015. A total of 327 patients with VA-associated HFS underwent their first MVD at our institution. Among them, the traditional technique was performed in 153 patients and the biomedical glue sling technique was performed in 174 patients. We measured effectiveness at 1 day, 7 days, 1 month, 3 months, and 1 year after MVD surgery. Results In the traditional technique group, the effective rate of MVD was 89.54%, 88.89%, 89.40%, 88.44%, and 86.71%, the incidence rate of complication was 5.23%, 4.58%, 3.97%, 2.72%, and 0.70%; in biomedical glue sling technique group, the effective rate of operation was 96.55%, 96.55%, 97.66%, 95.86%, and 95.76% (P < 0.05), the incidence rate of complication was 8.62%, 8.62%, 7.60%, 4.73%, and 2.42% (P > 0.05). Conclusion When the HFS were associated with the VA, the effective rate of biomedical glue sling technique of MVD was higher than the traditional technique, and there was no statistical difference between the two groups about the incidence of complication.
