The human eye is covered by the upper and lower eyelids. The eyelids are composed of skin, subcutaneous tissue, muscles, lids and conjunctiva. As we age, both the upper and lower eyelids may experience skin laxity, orbicularis oculi hypertrophy and fat protrusion. The lower eyelid not only does not have the lifting muscle to counteract gravity, but also has the cheek and upper lip pulling downward during mouth opening, adding to its gravitational effect, so loose skin, hypertrophic orbicularis muscle and bulging fat often form bags on the lower eyelid and the lower part of the orbit below it. Eye bags occur at different ages and are related to various factors such as living environment, habits, nutrition, rest, occupation, and genetics of each individual. Genetics is an important factor, and it becomes more pronounced with age (skin aging usually starts at age 30). In addition, if you suffer from kidney disease, during pregnancy, lack of sleep or staying up late and fatigue can also cause the accumulation of body fluid in the eyelids and the bulging of fat in the orbital diaphragm to form bags under the eyes. The bags under the eyes can easily make people look old and haggard and affect their beauty, and they can be removed through cosmetic outpatient surgery without hospitalization. Therefore, under-eye bag surgery is one of the common procedures in cosmetic surgery. There are various manifestations of under-eye bags, according to which they can also be divided into various types, such as: simple skin laxity type; orbital fat herniation type; orbital fat increase type; simple orbicularis oculi hypertrophy type; mixed type accounts for most of the occurrence of lid bags, that is, there is weak laxity of the skin, orbicularis oculi muscle, and weakness of the orbital septum, orbital fat bulge, with or without cheek lid sulcus, common in middle-aged and old people. For younger people with less obvious skin laxity, but with bulging orbital fat on the lower lid, the internal incision method is used to remove the bulging orbital fat through a small incision on 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 fully recover within a week. This method has its limitations, as it is unable to remove the loose lower lid skin, and for older people with loose musculoskeletal tissues, correction with this method may aggravate the aging appearance of the lower lid. Therefore, both men and women will develop lower eyelid bags as they age. If the skin is not lax, it is not necessary to remove the skin as long as the exposed fat is removed. For middle-aged and older candidates with lax skin and orbital septum. The surgery often requires removal of excess loose skin and correction of fine wrinkles in the skin of the lower lid using an external incision in order to achieve satisfactory results. The incision is usually designed 1-2 mm from the lower lid lash margin, parallel to the edge of the lower eyelid and slightly beyond the outer corner of the eye. This way, the post-operative incision marks are hidden and generally not visible. Care must be taken when removing the skin of the lower eyelid, as removing too much skin from the lower eyelid can produce lower eyelid ectropion, which is not only very unsightly, but can also damage the eye over time. Theoretically, there is a possibility of postoperative lid ectropion with the external cut and a postoperative scar left on the lower lid margin (although very inconspicuous). For those who have an obvious bulging appearance and a deep cheek lid sulcus, the “orbital septum release” method has been used in recent years to correct the problem. This procedure can be performed using a conjunctival approach or a lower lid margin incision, where the orbital septum is completely opened, the orbital septum fat is released and fixed with sutures in the buccal lid sulcus, thus eliminating the bulging appearance and also filling up the buccal lid to restore the natural transition of youth. Ideal eye bag surgery standards: 1, after the surgery bags disappear, local flat no obvious depression or protrusion. 2, the length of the incision on both sides, the distance from the lid margin width is the same, there is no unevenness. 3, skin incision eye bag plastic surgery, the lower lid skin fine wrinkles should disappear. 4, after skin incision blepharoplasty, the incision l traces should be 2 months later in 1m far away, the next person can not see. The natural curvature of the lower lid margin after surgery should remain the same as before surgery, and the normal curvature of the lower lid margin should not be changed or even become flat to remove excess lower lid skin. 6. After surgery, there should be no subcutaneous hard knots in the eyebags when touched by hand. 7.After surgery, the eyes should look refreshed, without complications such as lid ectropion and tearing. Eye bag surgery is the surgical removal of excess orbital fat or skin, too much orbital fat removal will make the lower lid sunken and affect the beauty. Excessive skin removal can result in lower lid ectropion, which is more serious. Therefore, before eye bag surgery, you should clarify three points: 1, eye bag surgery can only reduce, it is impossible to completely remove the bags. 2, after surgery, there may be temporary lid ectropion and incision red hard phenomenon, it takes 2-3 months to gradually recover. 3, with the increase of age bags under the eyes will gradually produce, generally an eye bag plastic surgery can maintain the cosmetic effect for 5-10 years. After the eye bag elimination surgery, reasonable and appropriate self-care is very important, because it can reduce the occurrence of postoperative complications and accelerate the healing of the wound: 1, first of all, adequate sleep, long-term lack of sleep, is an important reason for the premature appearance of eye bags aggravation. Modern research has proved that good sleep, can significantly improve the blood circulation of the eyelid tissue, can make the layers of tissue around the eyes to maintain good vitality, so as to effectively prevent the occurrence of bags and aggravation, if long-term sleep deprivation, the periocular tissue chronic fatigue, blood flow disorders, so that the layers of tissue degenerative aging changes, coupled with the role of gravity, making the bags appear prematurely, and rapidly increase aggravation. In addition, balanced nutritional intake, health care massage, high-quality nutritional creams are effective ways to prevent the recurrence of under-eye bags. Special note: the lower eye bag surgery does not improve the appearance of “dark circles” caused by long-term overwork. 2, the day after the surgery to remove the bags under the eyes, the local wound may appear a small amount of bleeding, can be used palm light pressure on the gauze area 15-30 minutes to stop bleeding; if there is more than bleeding, eyelid obvious swelling, all the bandage gauze soaked in blood, the eye feels distended and painful, vision is unclear, etc., should immediately go to the plastic surgery hospital for treatment to avoid serious consequences. 3, 2 weeks after surgery do not eat tobacco, alcohol, fishy, spicy and other stimulating food, to light and nutritious diet is better, should increase the intake of protein, while eating more fruits and fresh vegetables to promote wound healing. It is strictly forbidden to take aspirin, hormones and other drugs within two weeks after surgery. Before removing the stitches after surgery, take care not to wet the wound when washing the face, and keep the wound clean and hygienic to prevent infection. 4. Within 24 hours after surgery, you can use an ice pack for local cold compress to prevent secondary bleeding of the wound and reduce edema. Postoperative gauze pressure on the eyelid area for 1-2 days will be lifted by itself 24-48 hours after surgery, and no further bandaging is necessary; apply erythromycin eye ointment to the eyelid wound daily, 2-3 times/day. Be careful not to be too active for a week after surgery to prevent bleeding in the operative area; daily sleep time can be reduced appropriately and the head padded during sleep to reduce eyelid swelling. 5. A quiet and comfortable environment with fresh air circulation should be used for recuperation after surgery to avoid aggravating the wound swelling due to low head position. Oral antibiotics should be taken for 3-5 days after surgery to prevent wound infection, and intravenous fluids can be given for 1-3 days if necessary. Try not to read books, watch TV and operate computers and other activities that use more eyes within 2 days after surgery. In the diet 6, 5-7 days after surgery to remove the stitches. A day after the removal of the stitches can be localized hot compresses to promote the edema to subside as soon as possible. Overall, the risks of eye bag surgery are not too big, but it is not easy to achieve perfection. When you decide to choose surgery to eliminate under-eye bags, you must be very careful, you should choose your body in the best condition, and choose a regular professional and safe plastic surgery hospital.
