Double eyelid surgery, or blepharoplasty, or blepharoplasty, has so far been performed by these two methods – the buried suture method and the incision method. Blepharoplasty refers to a procedure in which sutures are placed directly between the skin and the lid, causing the skin of the upper eyelid to adhere to the lid, thus forming a blepharoplasty. There are three-point, five-point, half-cut, and full-cut eyelids, of which three-point and full-cut are the most widely used methods. The three-point method is also often called Korean three-point and Korean minimally invasive, although in fact, there is no such thing as Korean or Chinese, and the methods of both Chinese and Korean doctors are the same. First, buried line method Advantages: not cut the skin, no skin, no lipids, only a suture line along the drawn double eyelid line fixed in a few places, compared with other methods, less trauma, fast recovery, basically can not see the scars after the operation. Disadvantages: Generally speaking, the buried eyelid method will have different degrees of recovery in about 2 years. Indications: buried line double eyelid does not cut the skin, less changes to the eye, so there is no way to solve the problem of thick upper eyelid skin, puffy eyes, upper eyelid skin laxity, etc. It is only suitable for thin upper eyelid skin, eyebrow-eye distance is large. Based on the fact that people still don’t know much about plastic surgery, some of the “smart businessmen” will package the ordinary eyelid surgery as “polymer double eyelid”, “bio-welding double eyelid”, “PC double eyelid”, “PC double eyelid”, “polymer double eyelid”, “bio-welding double eyelid”, “bio-welding double eyelid”, and so on. “, “PC positioning double eyelid”, “nano scarless double eyelid” and so on, make up a bright name, the price rises a few times or even dozens of times. Second, the incision method – minimally invasive three-point style in the upper eyelid skin to make three length of 2-3 millimeters of discontinuous small incisions, by these three small incisions to the double eyelid suture fixed, and at the same time, if necessary, you can also be a small amount of fat through the three small incisions extracted. Advantages: Smaller incisions, less trauma, and generally faster swelling. The three-point method makes three small incisions, which is slightly more traumatic than the threaded method in exchange for a permanent double eyelid. Disadvantages: Limit the length of the incision and what the surgeon can achieve, so the indications for the three-point method are basically similar to the buried thread method. Indications: only suitable for candidates with thin upper eyelid skin, not so suitable for candidates with thick upper eyelid skin, puffy eyes, and loose upper eyelid skin. Third, incision method – full cut double eyelid By making an incision in the skin of the upper eyelid, excess skin and fat tissue is removed, and then the eyelid skin is fixed to the desired height of the eyelid plate, thus forming a heavy eyelid. With a full eyelid, the incision is longer, so it provides the surgeon with a higher degree of control, so it is suitable for a wider range of tissue conditions. Finally, it is important to say that medical innovation is very difficult, double eyelid surgery has been developed by ophthalmologists to treat trachoma, and there are just so many ways to do it, and different surgeons may improve on the details, but as of now there are no revolutionary surgical methods that have been reported.
