As we age, many people’s skin ages, especially the skin of the eyes and face, aging is more obvious, the skin of the lower eyelid relaxes, the orbital septum support decreases, the orbital septum then prolapses, and the tone of the orbicularis oculi muscle decreases, a bag-like expansion is formed above the infraorbital rim, and the cheek-lid furrow deepens, which is known as under-eye bags. If bags have formed and no self-improvement occurs, this means that the formation of bags is due to pathological changes in tissue structure; this nature can only be corrected through cosmetic surgery. The pathological basis for the formation of under-eye bags has already been mentioned, so the principle of under-eye bag correction is to remove part of the excess orbital fat, tighten the orbital septum to enhance its support, shorten the orbicularis oculi muscle to improve its tension, and remove excess skin to eliminate wrinkles, but of course there are different forms of under-eye bags. For example, the puffy appearance is the main appearance, the wrinkled appearance is the main appearance, and the deepening of the cheek lid furrow is the main appearance, so there are different forms of expression, and the corresponding methods can be used to correct. If the bags are mainly in the form of puffy appearance, and the tension of the skin tissue is still possible, the conjunctival surface approach can be used for correction. In this procedure, the orbital fat outside the bulging area is partially removed through a small incision in the conjunctival surface to eliminate the bags. This method is less invasive and there is no trace of appearance, only some people have mild postoperative swelling and bruising, but they can all recover completely within a week. In external incision surgery, the incision is made along the lower eyelash edge of the lower lid to the outer canthus, and the bulging fat is removed after the incision is separated. At the same time, the lower lid skin is tightened and the excess lower lid skin is removed to remove the lower lid skin wrinkles. The incision is concealed and it is difficult to see the incision marks 1-2 months after healing. This method is mainly used for the lower eyelid skin laxity and lower eyelid orbicularis muscle hypertrophy (pseudophakic bags), which are mainly manifested by the lower eyelid skin laxity and wrinkles, orbital septum fat not protruding, sometimes more atrophied and mildly depressed, or lower eyelid orbicularis muscle hypertrophy related to family genetics. Patients with hypertension and diabetes should inform the doctor of their condition during the initial consultation so that the doctor can confirm the surgical plan, and women should avoid menstruation; post-operative bruising and edema around the eyes is common, local cold compresses for two days after surgery and hot compresses after the third day can reduce the degree of bruising and edema and help the edema subside. External incision method eye bag plastic surgery after the surgery due to the eye orbital machine relaxation, loss of normal tension, a short period after surgery, mild ectropion, this situation can generally be restored to normal in 2-3 months after surgery.
