All patients undergoing facial cosmetic surgery are required to have medical photographs taken. The purpose of medical photography is multiple. The photographs provide accurate documentation of the appearance of the part of the body that will undergo surgery. Although the surgeon examines the patients in his office on more than one occasion, the photographs are necessary for him to do his " homework" the day before the surgery. The photographs are also displayed on a screen in the operating room during surgery for easy reference. They show the patient’s features affected by the force of gravity in a standing position. Some of these features change considerably while the patient is lying on his or her back on the operating table.
