Bell's palsy - What is Bell's Palsy?

Bell's palsy is paralysis of the muscles of the face, caused by acute malfunction of, or damage to, the nerve that supplies them.
An attack frequently occurs without apparent cause.

Symptoms of Bell's palsy

Facial features lose their symmetrical arrangement, and the mouth droops at one corner. Paralysis of
the muscles results in loss of control over saliva or tears, so that the patient may dribble or appear to  cry.

Bell's palsy treatment

It is important that a physician is consulted immediately because swift treatment with corticosteroid drugs may help. Many patients recover spontaneously; about 70 percent recover completely within 4 to 6 weeks, and about 20 percent make a partial recovery.
Surgery to the affected nerve may restore partial nerve function.
