Medical Treatment and Grading of Bell’s Palsy

The main aim of this thesis was to evaluate the effect of prednisolone and valaciclovir in a large number of Bell’s palsy patients. The incidence and intensity of pain around the ear, in the face or in the neck during the first two months of palsy, and its prognostic value, was also assessed. We also investigated how study design and choice of analysis method affect the rate of facial recovery. Furthermore, the agreement between the Sunnybrook, House-Brackmann and Yanagihara facial grading systems was evaluated.From May 2001 to September 2007, a prospective, randomised, double-blind, placebo-controlled, multicentre trial with 12-month follow-up was performed in patients with Bell’s palsy. Of 839 randomised patients, 829 were included in the intention-to-treat analysis; 206 received placebo plus placebo, 210 prednisolone plus placebo, 207 valaciclovir plus placebo, and 206 prednisolone plus valaciclovir. Time to recovery was significantly shorter in the 416 patients who received prednisolone compared with the 413 who did not (p<0.0001). At 12 months, 300 of 416 patients (72%) in the prednisolone group had recovered compared with 237 of 413 patients…
