1.What is under-eye bags? Under-eye bags are the signs of eye bloating and aging caused by the sagging of the skin of the lower eyelid, the accumulation of orbital fat protruding from the septum or the thickening of the orbicularis oculi muscle, usually called under-eye bags. 2.How are under-eye bags formed? The formation of eye bags is a manifestation of skin aging. As we age, skin laxity and orbital fat accumulation protrude from the lower eyelid, and the lax skin and protruding orbital fat form a wreath-shaped eye bag in the lower eyelid and the lower part of the orbit below it, forming a bag-like deformity of the lower eyelid. Some young patients do not have skin laxity and orbital fat accumulation protruding from the lower eyelid, but due to orbicularis oculi muscle hypertrophy can form a whorl-shaped deformity of the lower eyelid. 3.What are the reasons for the formation of under-eye bags? The formation of eye bags is mainly due to the following factors: (1) as the human body ages, degenerative changes occur in the skin, subcutaneous tissues, muscles and their related structures, causing the skin to become thinner, less elastic and sagging, while the orbital fat protrudes into the sagging skin to present changes in eye bags. (2) Congenital genetic factors cause orbicularis oculi hypertrophy, making the skin of the lower eyelid appear whorled, especially obvious when smiling. (3) Traumatic injury to the orbicularis oculi and orbital diaphragm, with the orbital fat protruding with the weak skin to form a pouch-like deformity of the lower eyelid. In addition, due to fatigue, poor sleep, excessive nightlife and systemic or chronic diseases are likely to induce or accelerate the formation of bags under the eyes, and even present dark circles around the eyes. 4.When does under-eye bagging usually start? Eye bags occur at different ages, and each person’s living environment, habits, nutrition, occupation, genetics and many other factors. Generally speaking, skin aging usually starts from the age of 30, and its aging speed has obvious individual differences. The eyelid skin is one of the thinnest skin in the human body, and the eyes are in the most exposed part of the body, so the lower eyelid bag-like deformity formed by the aging of eyelid skin is most easily detected and paid attention to. 5.How to distinguish between real and pseudo eye bags? The formation of bags under the eyes is divided into real and pseudo. The causes of pseudobags include crying, poor sleep, excessive nightlife, local inflammation of eyelids, temporary eyelid edema caused by food, drug or cosmetic allergies, etc. In these cases, the eyelid edema will subside and improve with the elimination of the cause and local treatment. However, due to the aging of the tissues, skin laxity, orbital fat accumulation, orbicularis oris muscle hypertrophy and the formation of true eye bags is very easy to lower eyelid protruding pouch-like changes, any drugs and high makeup is also difficult to make it disappear and cover up, and this lower eyelid bloating, laxity, sagging will become more and more obvious with age. Pseudo-eyebags, such as not eliminating the cause of the disease, let it continue to develop will also form true bags. 6.What are the clinical manifestations of under-eye bags? The clinical manifestations of under-eye bags are mainly in the following forms: (1) lower eyelid hanging deformity mainly characterized by skin laxity; (2) lower eyelid bloated deformity mainly characterized by the prominence of intraorbital fat accumulation; (3) lower eyelid whorl deformity mainly characterized by orbicularis muscle hypertrophy. 7, who are suitable for cosmetic eyebag surgery? Physically healthy, mentally normal, active request for surgery under-eye bags patients are suitable for cosmetic surgery under-eye bags. 8, bags under the eyes before surgery to do what preparation? (1) local inflammation around the eyes must be cured before surgery. (2) a history of bleeding patients need to check the platelets and bleeding, clotting time. (3) Female patients should avoid menstrual period as much as possible. (4) Surgery should be postponed during pregnancy. (5) Stop using steroid hormones and aspirin and other anticoagulant drugs 7-10 days before surgery. 9.Why can’t non-surgical treatment eliminate under-eye bags? Once formed, the only solution is surgery, so far, there is no effective non-surgical treatment to eliminate under-eye bags, some auxiliary treatments such as eye skin maintenance, eye massage, etc. can only slow down the aggravation of under-eye bags, and almost no effect on the elimination of under-eye bags. Therefore, eye bags cosmetic surgery is the most common method to remove under-eye bags, but also an important part of eye cosmetic surgery. 10.What are the surgical treatment methods for under-eye bags? As the clinical manifestations of under-eye bags are in many forms, thus different surgical methods are used for different cases. If the skin is not loose, only the exposed fat is removed, there is no need to remove the skin, and the original protruding skin has enough elasticity to be readjusted to a flat and smooth surface. According to the clinical manifestations of under-eye bags, there are two main methods of surgical treatment for under-eye bags: (1) intra-ocular method. That is, a small incision is made from the lower eyelid vault inside the eye, and then the fat is removed behind the orbital diaphragm, and then the vault incision can be closed. The biggest advantage of this method is that there is no skin incision, so it is often used for young patients with more fat in the orbital septum and no skin laxity or no obvious skin laxity. This method is not suitable for patients with lower eyelid skin laxity, nor for patients with orbicularis oculi hypertrophy, so the indications are very limited. (2) Extraocular approach. The extraocular incision is usually designed 2-3 mm from the eyelash margin of the lower eyelid, parallel to the edge of the lower eyelid and slightly beyond the outer corner of the eye, where the skin is incised, some of the orbicularis oculi and orbital fat is removed, and a moderate amount of loose lower eyelid skin is excised. This method is commonly used in patients with more orbital fat, significant skin laxity or orbicularis oculi hypertrophy. The biggest advantage of this method is that it is suitable for any kind of eye bags, the shortcoming is that the lower eyelid leaves incision marks, but the improved minimally invasive, fine suture technique can make the lower eyelid incision marks more concealed, generally not obvious or not visible. 11.What is the post-operative care for eye bags? Eye bag surgery can generally be completed in the outpatient operating room, after surgery patients can go home to rest and use their eyes as little as possible, 24 hours after surgery you can remove the dressing on the wound, wipe away the blood scabs and eye secretions on the wound, 5-7 days after surgery you can remove all the sutures in the operating area. 12.How is the recovery after eye bag surgery? Although there is mild bruising or swelling in the eyelid area after eye bag surgery, it is normal, and the swelling usually starts to decrease in 5-7 days, and it takes about 1-3 months for the swelling to completely disappear.
