Facial paralysis
Alternate Names : Paralysis of the face
Definition
Facial paralysis is the total loss of voluntary muscle movement of one side of the face.
Overview & Considerations
About 75% of all adult facial paralysis cases are due to Bell's palsy, a condition in which the facial nerve becomes inflamed. Stroke may cause facial paralysis. When stroke is the cause of facial paralysis, the person may still be able to close the eye on the affected side, as well as wrinkle the forehead. People with Bell's palsy cannot do either of these. With a stroke, other muscles on one side of the body may also be involved.
Facial paralysis due to a brain tumor generally develops slowly and causes headaches, seizures, or hearing loss. In newborns, facial paralysis may result from birth trauma.
