Plastic surgery is a type of surgical treatment in which a surgeon makes an incision into the patient’s skin and uses various instruments to change the shape, size, or appearance of some part of the body. Plastic reconstruction is a type of surgical treatment that restores tissue or organs that have been damaged by disease or injury. Plastic surgery is a subset of plastic reconstruction. Plastic surgery can be defined as "a type of surgical treatment in which a surgeon makes an incision into the patient’s skin and uses various instruments to change the shape, size, or appearance of some part of the body." In plastic surgery, surgeons make incisions through tissue layers to provide more access for their work. This can be done with various types of tools including scalpels, knives and scissors. The goal is to provide more options for reconstructive procedures such as breast reductions or rhinoplasty (nose job). In plastic reconstruction, surgeons repair tissues that have been damaged by cancer, burns, or other trauma through the insertion of a graft.
