Overview

Bell’s palsy is an acute, idiopathic peripheral facial nerve paralysis affecting the seventh cranial nerve (CN VII). It presents as sudden unilateral facial weakness or complete paralysis that peaks within 48–72 hours. The annual incidence is 20–30 per 100,000, affecting men and women equally across all age groups. Common triggers include viral reactivation (particularly herpes simplex virus type 1), upper respiratory infections, pregnancy, and immune suppression.
