Facial nerve paralysis is an inability to move the muscles that control smiling, blinking, and other facial movements. Most of the time, facial paralysis is limited to one side of the face. Paralysis can occur if any part of the facial nerve, called the seventh cranial nerve, becomes inflamed or damaged.
