Eye bags, which occur mainly in the lower eyelids, are characterized by bloated and bulging tissues in the lower lids that hang in a pouch-like fashion. There are three fat globules below the orbital septum of the lower lid: inner, middle and outer. In middle-aged people, especially those who do not sleep well, due to orbital septal laxity, the fat ball will push out the orbital septum, forming a pseudo-orbital fat hernia in the upper equivalent of the infraorbital rim, i.e., bags under the eyes, accompanied by varying degrees of skin laxity. bags under the eyes of young people under the age of 20 years old are mostly caused by family heredity. The appearance of bags under the eyes seriously affects the appearance of people, giving them a tired and old appearance and the impression of low spirit, therefore, bags under the eyes surgery is increasingly becoming one of the common surgeries in cosmetic clinics. There are two types of incisions for under-eye bag surgery: the skin approach and the conjunctival approach. The dermal approach is also known as the “external” approach, while the conjunctival approach is also known as the “internal” approach. Skin approach (external incision) This is the most commonly used method for eye bag revision. Through the skin approach, not only the herniated orbital fat globules can be removed, but also the excess skin can be removed, which effectively reduces the wrinkles of the lower eyelid skin and the crow’s feet at the outer corners of the eyes, and achieves the double effect of “removing the skin and removing the lipids”. Clinical experience tells us that patients over 30 years old generally have different degrees of skin laxity, and after removal of the orbital fat globules, the laxity will be further obvious, so the general method of removing the orbital fat globules is to use an external incision method to remove the excess skin, in order to achieve good lower eyelid rejuvenation results. The amount of skin removal is very artful, too much will cause lower eyelid ectropion, too little wrinkle effect is not good. And this problem is not difficult for professional plastic surgeons to deal with. External incision incision is very hidden, generally parallel to the eyelid margin, along the eyelid margin of the outer row of eyelashes under the 1mm design, the outer corner of the eye in the direction of crow’s feet. The skin incision of the external incision method is usually sutured with 7-0 cosmetic suture, and the suture is removed in 4 days. The incision is not obvious, and the swelling is short (usually about 10 days have been basically recovered), and most of the patients can hardly find the traces of the incision after 3 to 6 months. Conjunctival approach (endotomy) Conjunctival approach (endotomy) is mainly suitable for young people with primary eye bags who do not have lower eyelid skin and muscle laxity. The advantages of this method are that there is no need to separate the orbicularis oculi muscle, there is little tissue damage, the incision is made in the conjunctival surface of the eyelid, and there are usually no sutures, and there are no exposed skin incision marks. The internal incision method requires a higher level of skill due to less exposure of the operative area, and is usually done by an experienced and specialized plastic surgeon. The internal incision method is not suitable for older people because it cannot effectively solve the problem of sagging skin of the lower eyelid, and even the sagging of the skin will be more obvious after the operation. In this case, the external incision method is usually used. Eye bag surgery, small trauma, fast recovery (usually about 10 days can be fully recovered), the effect is obvious.
