Plastic surgery encompasses both cosmetic and reconstructive surgery.
Cosmetic surgery is performed to reshape normal structures of the body in order to improve the patient's appearance and self-esteem.
Reconstructive surgery is performed to correct function impairments or abnormal structures of the body. Reconstructive surgery can be performed for congenital defects, facial trauma, skin cancer, and hand and breast reconstruction. It is generally performed to improve functions, but may also be done to approximate a normal appearance.
