A plastic surgery specialist is a physician with extensive training in the execution of plastic surgery procedures. Plastic surgery is the use of surgical procedures to rebuild or reshape injured or misshapen body parts. Congenital defects, such as a cleft lip or palate, can be corrected by a plastic surgery specialist. Injuries sustained during auto accidents also may require the services of a plastic surgery specialist. These procedures fall under the category of reconstructive plastic surgery. The other category of plastic surgery is cosmetic plastic surgery. Plastic surgery specialists often perform procedures like breast augmentation, face lifts, tummy tucks, liposuction, and lip injection as elective surgeries for patients who wish to make aesthetic improvements.
