Plastic surgery is a surgical specialty involving the restoration, reconstruction, or alteration of the human body. It can be divided into two main categories: reconstructive surgery and cosmetic surgery and it can change a person's appearance and ability to function. Reconstructive procedures correct defects on the face or body. These include physical birth defects like cleft lips and palates and ear deformities and cosmetic/aesthetic procedures alter a part of the body that the person is not satisfied with like reshaping the nose (rhinoplasty), removing pockets of fat from specific spots on the body (liposuction). The use of special lasers to remove unwanted hair and sanding skin to improve severe scarring are also parts of plastic surgery. Plastic surgery is performed by a plastic surgeon and Cosmetic Surgeon.
