Background: Few studies have reported about facial herpes zoster and its complications in the Korean dermatologic literature. Objectives: The purpose of this study was to investigate epidemiology, clinical features, and complications of facial herpes zoster. Methods: We analyzed 977 patients who visited Sanggye Paik Hospital between January 2002 and December 2017. We categorized them into 8 groups based on dermatomes. We investigated the correlations between clinical features, prognosis, and complications. Results: The most common site of involvement of facial herpes zoster was the ophthalmic branch (59.2%). Herpes zoster involving the ophthalmic and maxillary branches showed a significantly higher incidence rate of herpes zoster ophthalmicus than that involving only the ophthalmic branch (odds ratio 7.373). Age and periorbital swelling were significantly correlated with herpes zoster ophthalmicus (p＜0.001). Facial palsy was significantly correlated with otalgia and cutaneous ear involvement (p ＜0.001). Patients who received antiviral treatment within 3 days showed lower rates of postherpetic neuralgia (35.8%) than patients who received treatment after 4 days (45.4%) (p=0.002). Conclusion: Facial herpes zoster is associated with several complications. Age, periorbital swelling, otalgia, and cutaneous ear involvement are useful predictors of complications and prognosis. Early institution of antiviral treatment is required for better outcomes.
