What is facial paralysis?

Facial paralysis occurs when there is a loss of voluntary movement in the muscles of one, or both, sides of the face due to abnormal function of the facial nerves. Facial paralysis can affect a person’s ability to make normal facial movements, such as smiling, frowning, puckering, opening and closing the eye, and wrinkling the forehead. This paralysis can be complete or partial, affecting only certain regions of the face. While some facial paralysis symptoms are temporary, improving over time, others are permanent, depending upon the underlying condition.
