    Facial paralysis

    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:

    • 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 isa 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. Symptomscan includeheadaches, seizures, or hearing loss.

    In newborns, facial paralysis may be caused by trauma during birth.

    Other causes include:

    • Infection of the brain or surrounding tissues
    • Lyme disease
    • Sarcoidosis
    • Tumor that presses on the facial nerve

    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 problems, weakness, or paralysis.

    Tests that may beordered include:

    • Blood tests, including blood sugar, CBC, ESR, Lyme test
    • CT scan of the head
    • Electromyography
    • MRI of the head

    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 tohelp theeye close and improve the appearance of the face.


    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.
