Double eyelid surgery is medically called blepharoplasty or upper blepharoplasty. It is a kind of eye cosmetic surgery that has been carried out more in recent years. There are many methods, which can be roughly divided into three categories. One is the buried thread method, the other is the suture method, and the third is the incision and suture method. They are introduced separately as follows.

(1) Buried suture method This method uses sutures to form an artificial connection between the levator aponeurosis of the superficial tarsal layer and the subcutaneous tissue. When the eyelids are raised, double eyelids are formed. That is, double eyelids. The advantage of this method is that it is simple to operate and non-invasive. There is no bagging of the eyes after the operation, and no suture removal is required. You can go to work immediately after the operation, and the double eyelid wrinkles will be natural. If the operation fails for beginners or the patient is not satisfied with the effect, the original method can still be used. method or use the suture method instead. The disadvantage is that the double eyelids may disappear. The thread management method is suitable for patients with recessive double eyelids and those with single eyelids with thin skin and less fat.

(2) Suture method: This method compresses the skin and tarsal plate by ligating sutures to form strip scar adhesion at the sutures, causing double eyelids in the upper eyelids. Sutures are usually removed 7 days after surgery. The technique of this method mainly lies in the ligation sutures. The tightness should be moderate and the eyelashes should be slightly upturned. If the sutures are too loose, the adhesion will not be strong and the double eyelids may disappear. If the sutures are too tight, the skin will easily form wrinkles and look unnatural. This method is suitable for patients with normal eyelids or thin eyelids, and no or only slight relaxation of the upper eyelid skin.

(3) Incision and suturing method This is a method that requires an incision. Before surgery, the height of the double eyelid should be carefully designed, and the crease line of the upper eyelid skin and the upper boundary of the skin to be removed should be marked. Then make an incision along the pre-designed double eyelid line to remove excess loose skin and excess fat. Finally, intermittent sutures are made with 5/0 silk thread, and the stitches are removed 7 days after the operation. The characteristics of this method are that the double eyelid wrinkles are deep and clear, and last for a long time. The disadvantage is that patients are somewhat afraid of surgery, fearing that if it fails, it will lead to "scarred eyes." This method is suitable for patients with loose upper eyelid skin, thick upper eyelid skin, and large amounts of subcutaneous fat in the upper eyelid, commonly known as "blister eyes."
