Initial inspection of the patient demonstrates flattening of the forehead and nasolabial fold on the side affected by the palsy. When the patient is asked to raise his or her eyebrows, the side of the forehead with the palsy will remain flat. When the patient is asked to smile, the face will become distorted and lateralize to the side opposite the palsy.
