There are two main categories of eyelid surgery when classified by surgical method: one is the incision method and the other is the non-incision method. Incisional eyelid surgery: is a method in which the skin of the upper eyelid is to be incised with a scalpel and a series of plastic surgery treatments are performed through this incision. The typical procedure for this method is the Fonada’s method. The basic procedure is to first remove a strip of skin with a scalpel or surgical cut in accordance with the designed surgical incision line on the upper lid, then a strip of orbicularis oculi muscle and some loose fascial tissue below the incision needs to be removed, and the orbital diaphragm is cut or a loose drooping orbital diaphragm is removed. The excised orbital fat wound needs to be thoroughly hemostatic to prevent the orbital fat from retracting into the orbital diaphragm and causing a retrobulbar hematoma. The sutures are commonly used at home and abroad: from the lower edge of the incision, through the upper edge of the lid or the levator aponeurosis, to the upper edge of the incision, and then knotted. Generally 7-10 stitches are required on one side of the upper lid. The stitches are removed 4-6 days after surgery. This incisional blepharoplasty has a wide range of indications, especially for those with loose upper lid skin and bloated upper lids (bubble eyes). This method allows you to control the shape of the double lid at will and its results last the longest. The disadvantage is that people with severe scarring should not use this method. In addition, the swelling time after surgery is long, usually requiring a 1-3 month recovery period.
