Effects of Acupuncture on Refractory Bell's Paralysis and Hunt's Syndrome-Examination of 29 Patients with a Minimum ENoG of 0% and NET scale-out-

Abstract

We retrospectively investigated the effects of acupuncture on refractory peripheral facial paralysis. Among patients with Bell's palsy or Ramsay Hunt syndrome (type II) who underwent acupuncture between August 1996 and June 2004, were 29 patients with a minimum electroneuronography (ENoG) percent response of 0%, and NET scale-out (14 patients with Bell's palsy, 15 with Ramsay Hunt syndrome). Demographically, they 21 males and 8 females, with a mean age of 44.3±12.8 years. Their disease duration, and paralysis score assessed using the 40-point method (Yanagihara's method) were 43.2±23.9 days and 10.2±2.7 points, respectively. To evaluate treatment response, we employed the paralysis score, and a sequela score assessed using a modification of the sequela evaluation method designed by Nishimoto and Murata et al. The paralysis score exceeded 36 points within 6 months after onset. Five patients (17.2%) without sequelae were regarded as having achieved complete recovery, and 24 (82.8%) as having achieved incomplete recovery. When the minimum ENoG is 0%, recovery within 6 months beyond onset is considered impossible. The results suggest, however, the efficacy of acupuncture.
