Plastic surgery is not, contrary to popular belief, solely about cosmetic surgery. Tummy tucks, face lifts, nose jobs - these are certainly covered under the umbrella of plastic surgery, but surgeries that correct congenital abnormalities, burns, or traumatic injuries are also considered a part of plastic or reconstructive surgery. This could be to retain or create a more regular appearance for the person involved, but is also often performed in order to improve function as well.
