 note = {A series of 34 cases of hemifacial spasm (HFS) have been evaluated using compound muscle action potential (CMAP) amplitude recordings at orbiculalis oculi. The cause of HFS consisted of 28 patients of idiopathic HFS,2 patients of cerebellopontine angle tumor and 4 patients of secondary to peripheral facial palsy. The mean rate of CMAP amplitude compared with normal side showed 83.4% in idiopathic group, 61.0% in group of cerebellopontine angle tumor and 64.8% in group of secondary to peripheral facial palsy. The CMAP amplitude is tend to decrease in patients with longer duration in idiopathic HFS group. HFS with cerebellopontine angle tumor and secondary to peripheral facial palsy indicated more reduction of CMAP amplitude probably due to axonal degeneration.},
