The application of endoscope in clinical medicine is nothing new. The application of endoscope in plastic and cosmetic surgery is a new technology developed in recent years, which is currently limited to forehead rhytidectomy. During the operation, the endoscope is introduced through a small incision in the scalp. Under the direct vision of endoscope, the deep surface is accurately separated, and muscles are cut or removed with special tools. Then push the skin and scalp upward and backward, and tighten the excess part of the forehead, that is, pile it on it and on the pillow.
