The practice of plastic surgery encompasses the restoration, rejuvenation, and enhancement of the patient through the art of surgery. Plastic surgery can be divided into two main areas: reconstructive & aesthetic/cosmetic surgery. Reconstructive plastic surgery is performed to correct functional impairments caused by burns, traumatic injuries such as facial bone fractures/breaks, congenital abnormalities such as cleft palates/cleft lips, developmental abnormalities, infection/disease, and cancer/tumors. Reconstructive plastic surgery is usually performed to improve function, but it may be done to approximate a normal form or appearance. Aesthetic or cosmetic plastic surgery involves techniques intended for the "enhancement" of an individual's appearance through surgical and medical techniques and is specifically concerned with maintaining normal appearance, restoring it, or enhancing it beyond the average level toward some aesthetic ideal.
