Cosmetic (整形) surgery is usually performed to correct a physical abnormality or to enhance an otherwise normal physical feature and thus improve appearance. Cosmetic surgery is an extremely broad field that may offer reconstructive surgery for a patient after a damaging burn or other physical injuries yet can also be used to smooth out wrinkles or reshape a nose. Cosmetic surgery was first used regularly after World War I, when treatment and reconstruction of war injuries gave hope to young soldiers.

As recently as fifty years ago, as the rich and famous began opting for elective cosmetic surgery, the subject was whispered about and considered taboo. Celebrities（名人） would disappear for months and then appear after secret cosmetic surgery looking younger, prettier, and thinner. Over time, cosmetic surgery has become accepted and even encouraged in some circles. Today there are even television reality shows about it.

Some of the more popular forms of cosmetic surgery are liposuction(抽脂术), in which excessive fat is sucked out of the body with a tube and vacuum device; laser facial resurfacing, which smooths lines on the face around the eyes and mouth and eliminates facial blemishes（瑕疵); and hair replacement surgery, which fills in balding areas using a patient's own hair. There are many more forms of cosmetic surgery, including variations of these.

Anyone interested in cosmetic surgery should consider the risks and remember that it is, ultimately, surgery. Not all procedures come out exactly the way doctors and patients foresee, and recovery is just like any other surgery, complete with pain and the possibility of infection(感染). While cosmetic surgery is an option, patients should choose doctors wisely, obtain several references, and keep realistic expectations.
