The primary endpoint will be the time to complete clinical recovery (defined as 100 on the Sunnybrook facial nerve grading scale) from Bell's palsy. The subjects will be categorised as healed or not healed at months 1, 2, 3, 6 or 12 months. Treatments will be compared using the Generalized Wilcoxon rank sum test. Patients where data are missing and there is no healing time will be included as censored at the last visit when the patient was not healed.
