Plastic surgeons help create quality-of-life improvements for patients, generally working within a specialty that focuses on changing the appearance of various body parts or facial features. They work frequently to assist in the long-term care of burn patients and other victims of disfiguring injuries. Some plastic surgeons focus primarily on elective procedures such as facelifts, rhinoplasty, and breast augmentation and reduction. They may also work with other specialists to assist in corrective procedures for birth defects or natal injuries. Additionally, plastic surgeons are common consultants for oncologists, as some cancer surgeries may alter the patient's appearance; the plastic surgeon may be able to mitigate these effects.
