Facial nerve disorders occur when the nerve that controls facial movement and expression is damaged. They can occur as the result of a variety of factors. Viral infections, strokes, trauma, surgery, and tumors can all cause facial paralysis or weakness. In most cases, the infection goes away on its own within a few weeks to months. Corticosteroids and antiviral medications can increase your chances of a successful recovery if treatment is started early. Spasms of the facial muscles or eye can be the result of an irritated nerve or pressure from one of the blood vessels of the brain. In some instances, surgery may be required to remove the blood vessel causing the pressure on the nerve.
