Primary hemifacial spasm (HFS) has specific electrophysiological features, like the existence of lateral spread responses (LSRs) to the stimulation of facial nerve branches. The curative treatment of HFS is based on surgical microvascular decompression (MVD), although the outcome of this procedure is not always satisfactory.
