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 AXH 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. |
