Korean Medicine Treatments in Threepatients with Bell’s Palsy after Coronavirus Disease 2019 Infection: A Retrospective Case Series

Bell’s palsy is an acute facial paralysis caused by peripheral facial nerve dysfunction. The aim of this study is to assess the efficacy of Korean medicine in the treatment of three patients who were hospitalized and diagnosed with Bell’s palsy within 2 weeks of coronavirus disease 2019 (COVID-19) infection. The patients were administered with Korean medicine treatments, steroids, and antiviral drugs. Moreover, the Korean medicine treatments include acupuncture, pharmacopuncture, moxibustion, physical therapy, and herbal medicine. Symptom improvement was evaluated daily using the Yanagihara facial nerve grading system, a facial function evaluation tool. Furthermore, it was suggested that the patients affected by Bell’s palsy after COVID-19 infection may have a slower improvement in their treatment progress compared with those without COVID-19 infection in the acute stage.
