Patients with acute-onset peripheral facial palsy are often seen in the emergency department (ED), and differentiating peripheral causes from central causes is the first step in evaluation. Once the physician rules out a central cause, clinical judgment is used to determine the most likely cause for the peripheral palsy, as management differs depending on the cause. This article outlines the approach to managing a patient with peripheral facial palsy and discusses treatment based on the etiology of the palsy.
