Objective: The aim of this study was to demonstrate some influencing factors on the prognosis of microvascular decompression (MVD) for hemifacial spasm (HFS) and analyze follow-up results. Material and methods: From Jan 2001 to Dec 2011, One-hundred seventy two patients with HFS were managed with MVD surgery. The patients' mean age were 55 years ranged from thirty three to seventy four. They consisted of 51 males and 121 females. The patients were followed-up at regular intervals and devided as cured and unsatisfactory groups based on symptom relief. All the patients were evaluated before and after surgery and were compared with clinical characteristics and postoperative results. Results: A total 163 of 172 (94.8%) patients had symptom relief within one year after MVD surgery. The age, sex, duration of symptom, type offending of vessel and spasm side was not playing any significant roles in prognosis. Indentation of root exit zone was associated good clinical outcomes (p=0.02). Clinical outcome at 3 month after MVD also had better statistical correlation with good clinical outcome than those of 1 week and 1 month (p=0.02). Conclusion: MVD is an effective and safe surgical modality for the treatment of HFS. Results of this study indicate that if the patients who suffering from HFS have indentation of REZ intraoperatively, then the patients may have a good clinical outcome. To predict the prognosis of HFS, a regular follow-up period of at least 3months after MVD should be needed.
