The Scottish study cited earlier suggested that prednisolone, and not acyclovir, is useful for facial recovery in Bell palsy. [12]

A Cochrane review found no significant benefit to the use of antivirals over placebo in reducing the rate of incomplete recovery from Bell palsy. [58] This meta-analysis looked at 7 studies involving a total of 1987 patients treated between 1966 and 2008.
