Hemifacial spasm is defined as unilateral, involuntary, irregular twitching of all or parts of the muscles innervated by facial nerves. Here, we present a case of recurrent hemifacial spasm after microvascular decompression (MVD) treated with pulsed radiofrequency (PRF) treatment with good results. A 35-year-old woman suffered from recurrent hemifacial spasm after MVD that was refractory to medical treatment and botulinum toxin injections. We attempted a left facial nerve block twice. Then, we applied PRF at a maximum temperature of 42oC for 120 sec. Some response was observed, so we applied PRF two additional times. The frequency of twitch decreased from 3−4 Hz to < 0.5 Hz, and subjective severity on a visual analogue scale also decreased from 10/10 to 2−3/10. PRF treatment might be an effective medical treatment for refractory hemifacial spasm and has fewer complications and is less invasive compared with those of surgery. (Korean J Pain 2013; 26: 62-64)
