Plastic cosmetic surgery, also known as elective surgery, has become increasingly popular in recent years. There are a variety of reasons why people choose to undergo cosmetic surgery, ranging from medical reasons to personal enhancement or improvement. One of the most common reasons for plastic cosmetic surgery is to correct physical imperfections or deformities. For example, patients may undergo surgery to correct a cleft lip or palate, remove excess skin following massive weight loss, or repair a deviated septum.
