Plastic surgery is a surgical specialty involving the restoration, reconstruction, or alteration of the human body. It can be divided into two categories. The first is reconstructive surgery which includes craniofacial surgery, hand surgery, microsurgery, and the treatment of burns. The other is cosmetic or aesthetic surgery. While reconstructive surgery aims to reconstruct a part of the body or improve its functioning, cosmetic surgery aims at improving the appearance of it. Both of these techniques are used throughout the world. In the term “plastic surgery,” the adjective plastic implies sculpting and/or reshaping, which is derived from the Greek πλαστική (τέχνη), plastikē (tekhnē), “the art of modelling” of malleable flesh. This meaning in English is seen as early as 1598. The surgical definition of “plastic” first appeared in 1839, preceding the modern “engineering material made from petroleum” sense of plastic (coined by Leo Baekeland in 1909) by 70 years
