Eileen Chang’s famous book “Half a Life” once had a sentence “When you are young, 18 years can pass in a snap of the fingers, like a dream, but when you are in your middle age, the more you learn to cherish the days, because everything can never come back”, when you are in your middle age, you have to value yourself more and present the best of yourself to everyone. If there are bags under the eyes, accompanied by the lower position of the outer canthus, crow’s feet increase, etc., we should carry out eye bag surgery in time to restore the youthful elegance. The formation of bags under the eyes is mainly due to the ageing of the skin, the gradual aging of the subcutaneous tissue muscles gradually degenerative changes in the muscles in the skin become loose. The fat behind the eye diaphragm protrudes in front of the loose orbital skin, resulting in the appearance of bags under the eyes. There is also the possibility of congenital genetic factors, the orbicularis oculi muscle hypertrophy protrudes forward to form bags under the eyes. In addition, lack of sleep, fatigue, chronic diseases, etc. are important reasons for the appearance of bags under the eyes. The techniques commonly used in modern plastic surgery to remove under-eye bags include external and internal incision. The internal incision method is mostly applicable to young people, without obvious skin laxity, and there is no surgical scar after the operation. External incision method is mainly applicable to middle-aged and old people, skin laxity is obvious, the skin incision after surgery generally will not have obvious surgical marks, a few patients will have redness of the incision in the early stage, mild scarring, generally 1-3 months or so can be reduced. Complications of eye bag surgery and their management A variety of complications can occur after corrective surgery for eye bags, such as lower eyelid recession, lower eyelid ectropion, lower eyelid depression, swelling, bruising, eyelash loss, and so on. Lower lid recession is the downward displacement of the lower lid margin without ectropion. In mild cases, the outer sclera is exposed and the lid is separated from the globe; in severe cases, the sclera is severely exposed and the patient suffers from photophobia, tearing and other symptoms that affect the appearance. Different surgical methods are used to correct the condition depending on the degree of symptoms. Eyelid ectropion is a serious complication of eye bag correction surgery. Mild lower eyelid ectropion is mostly caused by the relaxation of orbicularis oculi muscle and loss of normal tension, which does not require special treatment, and can be restored to normal within 2-3 months. For severe ectropion, surgical correction is needed, but it affects the appearance after surgery, so it is important to prevent lower eyelid ectropion. Lower eyelid depression mainly occurs in the buccal sulcus area, which can be corrected by autologous fat graft filling. These are the main serious complications, for other complications, it is easy to correct and avoid.
