Bell's Palsy
Additional Information
Bell's palsy is a condition that causes sudden weakness in the muscles on one side of the face. In most cases, the weakness is temporary and significantly improves over weeks. The weakness makes half of the face appear to droop. Smiles are one-sided, and the eye on the affected side resists closing.
Bell's palsy is also known as acute peripheral facial palsy of unknown cause. It can occur at any age. The exact cause is unknown. Experts think it's caused by swelling and inflammation of the nerve that controls the muscles on one side of the face. It could be caused by a reaction that occurs after a viral infection.
Symptoms usually start to improve within a few weeks, with complete recovery in about six months. A small number of people continue to have some Bell's palsy symptoms for life. Rarely, Bell's palsy occurs more than once.
