Objective: MVD for hemifacial spasm still presents a challenge regarding postoperative outcome. Insufficient improvement in a great proportion of patients undergoing MVD for hemifacial spasm is a limitation for this treatment. The effect of a combination of preoperative imaging and intraoperative monitoring of lateral spread on the outcome is presented. Methods: From 1991 to 2004 a consecutive series of 33 patients with MVD for hemifacial spasm is analyzed retrospectively. Surgical technique consisted of a standard MVD in all cases. In 15 versus 18 cases lateral spread was monitored during surgery. Prior to surg…
