Paralysis of the face
Facial paralysis occurs when a person is no longer able to move some or all of the muscles on one side of the face.
Facial paralysis is almost always caused by:
In people who are otherwise healthy, facial paralysis is often due to Bell's palsy, a condition in which the facial nerve becomes inflamed.
Stroke may cause facial paralysis. With a stroke, other muscles on one side of the body may also be involved.
Facial paralysis that is due to a brain tumor usually develops slowly and causes headaches, seizures, or hearing loss.
In newborns, facial paralysis may be caused by trauma during birth.
