Effectiveness of steroids and antiviral agents in the treatment of Bell’s palsy

The combination of steroids plus an antiviral agent, is more efficacious than steroid monotherapy in treating Bell's palsy. This conclusion is supported by frequentist analysis, but not by the Bayesian approach as the Bayesian meta-analysis was inconclusive, suggesting some uncertainty in the effect size but this could be due to priors influence. Further research with advanced syntheses such as network and Bayesian meta-analysis is needed as well as more double-blinded randomized controlled trials.
