Abstract
INTRODUCTION: The purpose of this study is to report our experiences of hemifacial spasm(HFS) and microvascular decompression(MVD) over 13 years and discuss the related issues.
METHODS: From April 1997 to Febraury 2011, over 1,600 consecutive patients underwent MVD for HFS. Among them, 1,507 patients who underwent MVD for HFS with a minimum 6 months follow-up were enrolled in the study. The median follow-up period was 1.44 years (ranging from 6months to 9.5years) In this study, 1075 (71.3%) patients were women and 432 (28.7%) were men with a mean age of 47.7 years (range 19-77 years). Preoperative imaging studies including magnetic resonance images were performed. Electromyography and brain stem evoked potential were monitored intraoperatively and audiologic studies were conducted in every cases pre- and post-operatively. The Kaplan–Meier method was used to estimate the overall cure rate by SPSS software.
RESULTS: At the last follow-up examination 1,424 (94.5%) patients of total 1,507 patients exhibited the curable state, and 83 (5.5%) patients showed remained spasm(n=68) including recurrences(n=15). The major postoperative complications included permanent hearing loss in 15 (1.0%), permanent facial palsy in 10 (0.7%), cerebrospinal fluid leak in five (0.33%), and cerebellar infarction or hemorrhage in two (0.13%). There were no operative deaths.
CONCLUSION: MVD is a very effective, safe modality of treatment for HFS. We published many related issues of HFS and MVD, but still many issues are remained to be answered.
