What is the formation principle of single eyelid? Today, Alibang's editor will tell you about the formation principle of single eyelid and double eyelid, that is, why are you single eyelid or double eyelid from the genetic level? The single eyelid is determined by genes. If the letter Aa is used instead, the single eyelid is aa, and the double eyelid is AA or Aa.

As long as A exists, it will show double eyelids, and if not, it will show single eyelids. That is to say, parents with double eyelids can give birth to children with single eyelids, but parents with single eyelids may not give birth to children with double eyelids. Therefore, if you have a single eyelid, there is no way to change it. Don't blame your parents, just have a double eyelid operation. Next, Alibang Xiaobian will tell you about the knowledge of double eyelid surgery.

There are two kinds of eyelids, incision eyelids and embedding eyelids. But not all people are suitable, so you should choose according to your own situation. Next, I will compare them for you.

1、 Surgical methods

To cut the double eyelid is to cut at a moderate distance above the eyelid, cut a small piece of skin, cut off the excess fat, then sew the eyelids thread to the eyelid plate or the eyelid lifting fascia, cut the eyelid, fix the upper eyelid lifting fascia to the dermis and subcutaneous tissue where the double eyelid is needed, and then suture the skin.

The double eyelid plastic surgery is to suture the eyelids with the levator palpebrae muscle or the eyelid plate, and use surgical suture to penetrate from the eyelids to the conjunctiva where the double eyelid is needed, and then go back out of the eyelids. After knotting, the suture knot is buried under the skin. Generally, three stitches are needed.

2、 Postoperative effect

　　 Open the eyelids The effect lasts for a long time. The surgical wound needs to swell for a period of time, and the recovery time is long and swollen. If the incision fails, it is not easy to correct, and it is also impossible to restore the initial state of the eyelid. The embedded double eyelids will not swell without scar, but cannot be maintained for a long time. If the suture falls off, the double eyelids will gradually disappear. Many people will recover after a period of time, but as long as the plastic surgeon has enough skills, this shortcoming can be overcome. So each has its own advantages and disadvantages depending on how you choose.
