These symptoms include twitching, weakness, or paralysis, drooping eyelid or corner of the mouth, drooling, dry eye or mouth, impairment of taste, and excessive tearing in the eye. The condition involves the forehead and lower aspect of the face, and patients are often unable to keep an eye closed or to retain food in the affected side of the mouth. Inappropriate reaction to loud noises, taste disturbances and decreased tearing also represent some of the concomitant symptoms of this disease. The most important step in diagnosis is to determine whether facial paralysis occurred due to a problem in the central nervous system (as in stroke) or is it actually Bell’s palsy.

Corticosteroids are often used to treat Bell’s palsy, as they proved helpful in reducing inflammation of the nerve and shortening symptom duration; the key is to use them shortly after onset to attain the desired effect. Antiviral medications are sometimes added to the therapy regimen, and surgical nerve decompression is pursued in more challenging cases. Although a majority of affected individuals recover completely and spontaneously over time, some patients can be left with lifelong consequences.
