Abstract
- Twenty seven patients with hemifacial spasm were treated by facial nerve block at the foramen stylomastoideum and O'Brien block from January 1992 to March 1994. There were 16 female and ll male patients, a 1.5:1 ratio respectively. Most patients were 40-60 years old. Among the 27 patients treated by nerve blocks, 26 responded well to the facial nerve block, including two cases of O'Brien block. One patient failed to respond to the facial nerve block. Induced facial palsy disappeared within one or two months within the majority of patients. Among the 26 patients who received nerve block, 6 patients required a second block within 3 to 9 months. After successful nerve block, all patients were free of spasm for 1 to 16 months. Although the follow-up period was short in duration, these results suggest that facial nerve block is a satisfactory and reliable method in the treatment of facial spasm.
