Plastic surgery can be undergone due to medical reasons. One of the most common examples of such surgery is a lift in the eyes and around the forehead; it helps to reduce eye pain and headaches caused by this physiological defect (Occupy Theory). Another example is damage received as a result of an accident–a chemical or thermal burn, fracture, deep scars, malformation, and so on. Plastic surgery, in these cases, can be used to return a patient back to his or her original condition and appearance before the accident.
