What are eye bags? As we age and the earth’s gravity continues to act, the skin of the lower eyelid loosens, the orbital septum prolapses, and the tension of the orbicularis oculi muscle decreases, resulting in the formation of a pouch above the infraorbital rim and the deepening of the cheek grooves, which are known as under-eye bags. The age at which bags appear varies from person to person, with most occurring around the age of 40. They have a greater impact on the beauty of the appearance and give people a feeling of old age. Therefore eye bags have become one of the most common procedures in cosmetic surgery. Eye bags are divided into four categories: 1, lower eyelid skin laxity type 2, lower eyelid orbicularis oculi muscle hypertrophy type 3, orbital septum fat protrusion type 4, mixed type. Common methods of removing bags under the eyes Blepharoplasty can be broadly categorized into two types: 1 External incision method: the incision is made along the lower edge of the lower eyelashes to the external bared groove, and the bulging bags of fat are excised after the incision is separated. The orbital septum is repaired, while the lower eyelid skin is tightened, excess lower eyelid skin is removed, and lower eyelid skin wrinkles are removed. The incision is hidden, and it is difficult to see the traces of the incision after healing. It is mainly used for type 1, type 2, and type 4 bags.2 Internal incision method: it is to make a small incision in the conjunctival sac of the lower eyelid to remove excess orbital septal fat, and it is also used for some young patients with moderately or severely inflated lower eyelids and those with type 3 bags who do not have obvious skin laxity. There is no incision, avoiding incision scarring outside the skin, little trauma and light swelling. What should be paid attention to after eye bag surgery After eye bag surgery, should pay attention to rest, as little as possible to read books, computers and television, is conducive to swelling; oral antibacterial drugs for about 3 days; postoperative common bruising and edema around the eyes, the available ice packs cold compresses on the surgical area in order to reduce bleeding, to prevent swelling, general postoperative 5 days after the removal of stitches. After surgery, the patient’s eyelids are smooth, wrinkle-free, skin glossy, people look young and energetic, and the skin incisions generally do not have surgical traces, a few people will have redness of the incision in the early stage, mild scarring, usually 1-3 months to disappear. The surgical effect usually lasts for about 7-8 years. The correction of under-eye bags may have such complications, of course, part of the normal complications of surgery, while the other part may be due to the basic quality of the surgeon, professionalism and aesthetic point of view.1. Lower eyelid ectropion: mainly due to the excessive removal of skin. After eye bag surgery, mild lower eyelid ectropion will occur due to edema and bruising, etc. It can be treated without special treatment, and usually returns to normal within 2-3 months.2 Lower eyelid depression: this is due to excessive removal of orbital septum fat, and this surgical complication can only be corrected by autologous fat grafting filler if it ever occurs. It should be reminded that due to the lack of clear understanding of the formation of bags under the eyes, in the eyes of many people this surgery is very simple, and only a single surgical method is used, which often fails to achieve good results. Eye bag surgery is not as simple as it seems, only through the clinical experience, the regular hospital physicians on the different conditions of the correct judgment and implementation of the best cosmetic results, while avoiding the occurrence of surgical complications.
