Reconstructive and cosmetic plastic surgery are both subspecialties of plastic surgery, and they focus on different things. Doctors perform reconstructive surgery to restore a body part's function and appearance to normal.  They also correct deformities caused by trauma, cancer, burns, and congenital disabilities to help an individual return to normal. It is a medical necessity and sometimes part of health insurance coverage because of its importance.  Meanwhile, cosmetic surgery focuses on the aesthetic aspect of the body. It enhances the appearance and makes it appealing.  Some cosmetic procedures include liposuction, facelift, and breast reconstruction, which adjust the body's appearance.
