- Objectives: To evaluate the treatment effect of prednisolone and/or valaciclovir in Bells palsy patients with different baseline severity of palsy.Design: Patient data were collected from the Scandinavian Bells Palsy Study, a prospective, randomised, double-blind, placebo-controlled, multi-centre trial.Setting: Sixteen otorhinolaryngological centres in Sweden and one in Finland.Participants: Altogether, 829 patients aged 1875 years were treated within 72 h of palsy onset. Patients were randomly assigned to treatment with prednisolone plus placebo (n = 210), valaciclovir plus placebo (n = 207), prednisolone plus valaciclovir (n = 206), placebo plus placebo (n = 206). Follow-up was 12 months.Main outcome measures: Facial function was assessed using the Sunnybrook grading scale at baseline and at 12 months. Complete recovery was defined as Sunnybrook score = 100.Results: All patients, regardless of baseline severity, showed significantly higher complete recovery rates if treated with prednisolone compared with no prednisolone. In patients with severe palsy, recovery at 12 months was 51% with prednisolone treatment versus 31% without prednisolone (P = 0.02). Corresponding results were 68%versus 51% (P = 0.004) for moderate, and 83%versus 73% (P = 0.02) for mild palsy. In patient groups with moderate and mild palsy at baseline, significantly fewer prednisolone-treated patients had synkinesis at 12 months (P = 0.04 and P < 0.0001, respectively). For patients with severe palsy at baseline, prednisolone versus no prednisolone made no significant difference regarding synkinesis at 12 months. Valaciclovir did not add any significant effect to prednisolone regarding recovery rate or synkinesis at 12 months.Conclusion: Prednisolone treatment resulted in higher complete recovery rates, regardless of severity at baseline. Prednisolone treatment should be considered in all patients irrespective of degree of palsy.

- Objective: To evaluate if treatment start and age are related to the outcome in Bell's palsy patients treated with prednisolone. Study Design: Prospective, randomized, double-blind, placebo-controlled, multicenter trial. Setting: Sixteen otorhinolaryngologic centers in Sweden and 1 in Finland. Patients: Data were collected from the Scandinavian Bell's palsy study. A total of 829 patients were treated within 72 hours of onset of palsy. Follow-up was 12 months. Intervention: Patients were randomly assigned to treatment with placebo plus placebo (n = 206), prednisolone plus placebo (n = 210), valacyclovir plus placebo (n = 207), or prednisolone plus valacyclovir (n = 206). Main Outcome Measures: Facial function was assessed with the Sunnybrook grading system, and complete recovery was defined as Sunnybrook = 100. Time from onset of palsy to treatment start was registered. Results: Patients treated with prednisolone within 24 hours and 25 to 48 hours had significantly higher complete recovery rates, 66% (103/156) and 76% (128/168), than patients given no prednisolone, 51% (77/152) and 58% (102/177) (p = 0.008 and p = 0.0003, respectively). For patients treated within 49 to 72 hours of palsy onset, there were no significant differences. Patients aged 40 years or older had significantly higher complete recovery rates if treated with prednisolone, whereas patients aged younger than 40 years did not differ with respect to prednisolone treatment. However, synkinesis was significantly less in patients younger than 40 years given prednisolone (p = 0.002). Conclusion: Treatment with prednisolone within 48 hours of onset of palsy resulted in significantly higher complete recovery rates and less synkinesis compared with no prednisolone.

- Objectives. To study the correlation between Sunnybrook and House-Brackmann facial grading systems at different time points during the course of peripheral facial palsy. Study Design. Prospective multicenter trial. Setting. Seventeen otorhinolaryngological centers. Subjects and Methods. Data are part of the Scandinavian Bell's palsy study. The facial function of 1920 patients with peripheral facial palsy was assessed 5397 times with both Sunnybrook and House-Brackmann (H-B) facial grading systems. Grading was done at initial visit, at days 11 to 17 of palsy onset, and at 1 month, 2 months, 3 months, 6 months, and 12 months. Statistical evaluation was by Spearman correlation coefficient and box plot analysis. Results. Spearman correlation coefficient varied from -0.81 to -0.96, with the weakest correlation found at initial visit. Box plot analysis for all assessments revealed that Sunnybrook scores were widely spread over different H-B grades. With 50% of the results closest to the median, Sunnybrook composite scores varied in H-B grades as follows: H-B I, 100; H-B II, 71 to 90; H-B III, 43 to 62; H-B IV, 26 to 43; H-B V, 13 to 25; and H-B VI, 5 to 14. Conclusion. Gradings correlated better in follow-up assessments than at initial visit. As shown by the wide overlap of the grading results, subjective grading systems are only approximate. However, a conversion table for Sunnybrook and H-B gradings was obtained and is included in the article. It can be used for further development of facial grading systems.
