As a female friend, the most common plastic surgery should be to cut double eyelids, especially those with small eyes. In fact, cutting double eyelid surgery, also known as simulated double eyelid surgery, is called upper eyelid fold in eye plastic terminology. There are three most common surgical methods. 1, embedding method to simulate double eyelids: suitable for those with thin subcutaneous tissue of upper eyelid and inconspicuous orbital septum fat. Suture embedding method embeds suture knot between dermis and meibomian and keeps it permanently, which is stronger than suture ligation method, but it must master the correct anatomical level. Its disadvantage is that the buried suture knot is easy to loosen and the double eyelid is easy to disappear, but it can be buried again to form a firm adhesion. 2, suture ligation method to simulate double eyelids: suitable for those with large eye fissure, thin eyelid, less fat and no slack upper eyelid. Suture and ligation are simple and easy to operate. Usually the non-surgical sewing of double eyelids in beauty advertisements belongs to this category. When the surgical effect is not good, it can be corrected by incision. Those who are dissatisfied with the shape of the double eyelids can cut the knot and return to the original single eyelid within a few days after operation. Postoperative swelling was slight, and there was no obvious scar on the incision. 3, the incision method simulates double eyelids: it is to cut the upper eyelid, so that the double eyelids are anatomically similar to the natural double eyelids. This method is applicable to any subject. Double eyelids will not disappear. For elderly patients with wrinkle relaxation or orbital diaphragm fat swelling, a small amount and part of orbital diaphragm fat can also be removed to relieve the symptoms of upper eyelid relaxation and edema. The disadvantage is that postoperative swelling is obvious, and some patients have swollen for a long time, leaving a slight incision scar in the early stage. The above are the main methods and principles of simulating double eyelid surgery. You know, this kind of surgery can make women's eyes bigger and more attractive.
