With Bell’s Palsy, there been numerous clinical trials. The two main ones: one was that about 6 years ago and the other one was done about 20 years ago. There have been numerous since then – much research (actually around here at the House Ear Institute). The general outcomes of those trials: the first one, the outcome said that we should use antivirals and steroids. The second one, which was a much longer running trial said that we should just use steroids for the treatment of Bell’s Palsy. There haven’t been any other really significant advances since then – to my knowledge.
