[Treatment of Bell's palsy with acyclovir and prednisolone].
Many current studies have suggested that herpes simplex virus is a probable cause of Bell's palsy, and that treatment with antiviral agents such as acyclovir might benefit the patients. In the present study, 69 patients with Bell's palsy were treated with oral administration of acyclovir (2000 mg/day) and prednisolone (60-40 mg/day) at Ehime University Hospital between Oct. 1995 and Dec. 1998. Patients enrolled in this study met the following criteria: 1) severe or complete paralysis with a score lower than 20 by the 40-point Japanese grading system, and 2) treatment started within 7 days of onset. The overall recovery rate was 95.7% (66/69). The rate in patients who started this treatment within 3 days after disease onset was 100%, and this early treatment was highly efficacious in the prevention of nerve degeneration and resulted in a significantly better recovery. By comparison, the recovery rate in patients whose treatment was started 4 days or more after onset was only 84.2%. All patients who were given a diagnosis of zoster sine herpete and treated with acyclovir-prednisolone had a good outcome. These results suggest that early treatment, within 3 days after palsy onset, is necessary for effective acyclovir-prednisolone therapy of Bell's palsy.
