Herpes zoster oticus: treatment with intravenous acyclovir

Herpes zoster oticus generally has a poor prognosis, leaving many patients with permanent facial nerve dysfunction. This preliminary report describes results in seven patients treated for zoster; all were given intravenous acyclovir. Patients were infused with 10 mg/kg every 8 hours over a 7-day hospitalization period. Five of the seven patients showed some return of facial function at the time of discharge. At follow-up, 4 patients had achieved a House grade I result, 1 patient a grade II, and 2 patients a grade III. Reasons for the differences in final results are discussed, along with a recommended regimen for treatment.
