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

Facial paralysis is almost always caused by:

Facial paralysis that is due to a brain tumor usually develops slowly. Symptoms can include headaches, seizures, or hearing loss.
In newborns, facial paralysis may be caused by trauma during birth.
Other causes include:
Follow your health care provider's instructions on how to take care of yourself at home. Take any medicines as directed.
