Facial paralysis

Facial paralysis occurs when a person is no longer able to move some or all of the muscles on one side of the face.

Causes

Facial paralysis is almost always caused by:

  • Damage or swelling of the facial nerve, which carries signals from the brain to the muscles of the face
  • Damage to the area of the brain that sends signals to the muscles of the face

In people who are otherwise healthy, facial paralysis is often due to Bell's palsy. This is 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 drooping can be caused by a disorder such as Bell's palsy. This disorder is a mononeuropathy (involvement of a single nerve) that damages the seventh cranial (facial) nerve. The facial nerve controls movement of the muscles of the face.

Facial paralysis that is due to a brain tumor usually develops slowly. Symptoms can include headaches, seizures, or hearing loss.

What to Expect at Your Office Visit

The doctor will perform a physical exam and ask questions about your medical history and symptoms, including:

  • Are both sides of your face affected?
  • Have you recently been sick or injured?
  • What other symptoms do you have? For example, drooling, excessive tears from one eye, headaches, seizures, vision problemsweakness, or paralysis.

Tests that may be ordered include:

The doctor may refer you to a physical, speech, or occupational therapist. If facial paralysis from Bell's palsy lasts for more than 6 - 12 months, plastic surgery may be recommended to help the eye close and improve the appearance of the face.

Treatment

Treatment depends on the cause. Follow your health care provider's treatment recommendations.

Home Care

Follow your health care provider's instructions on how to take care of yourself at home. Take any medicines as directed.

If the eye cannot fully close, the cornea must be protected from drying out with prescription eye drops or gel.
