What Can Help a Droopy Eye Caused by a Traumatic Scar Under the Eye Pulling It Down?

My girlfriend was in a car accident and now has a scar from her forehead to her mouth. She has had some plastic surgery, but the doctors told her to have realistic expectations. Her mouth is still crooked, her cheek is looking better and there is a scar on her forehead. She is most concerned about the scar under her eye tugging it down and making it droopy. What kind of plastic surgery can be done to help correct that?
