Medical Management of Acute Facial Paralysis.

Acute facial paralysis (FP) describes acute onset of partial or complete weakness of the facial muscles innervated by the facial nerve. Acute FP occurs within a few hours to days. The differential diagnosis is broad; however, the most common cause is viral-associated Bell Palsy. A comprehensive history and physical examination are essential in arriving at a diagnosis. Medical treatment for acute FP depends on the specific diagnosis; however, corticosteroids and antiviral medications are the cornerstone of therapy. Lack of recovery after 4 months should prompt further diagnostic workup.
