As previously mentioned, 2012 guidelines from the AAN state that steroids are highly likely to be effective and increase the likelihood of recovery of facial nerve function in new-onset Bell palsy [6, 8]

Guidelines from the American Academy of Otolaryngology–Head and Neck Surgery Foundation (AAO-HNSF) were issued in November 2013 that also support the AAN guidelines. The guidelines recommend use of corticosteroids within 72 hours from the onset of symptoms. Antiviral agents (eg, acyclovir, valacyclovir) may be considered if a viral etiology is suspected, but only in combination with corticosteroids. [49]
