Abstract
The effect of antiviral agents on recovery from facial palsy in patients with zoster sine herpete (ZSH; varicella zoster virus reactivation without zoster) has not been evaluated because ZSH is difficult to diagnose early after onset. In this study, all 13 patients who received acyclovir-prednisone treatment within 7 days of onset, as confirmed by a positive PCR result, showed complete recovery. PCR-based early diagnosis of ZSH and antiviral therapy elicited an excellent outcome for recovery from facial palsy due to ZSH.
