A classic beauty model must have a pair of beautiful big eyes, so many people with small eyes want to make their eyes bigger. Open canthus surgery can make eyes attractive, and the success of open canthus surgery is closely related to many factors. In order to meet different people's choices of canthus surgery, surgical methods have also developed greatly. At present, there are two main methods of open-angle plastic surgery in clinic, one is internal angle plastic surgery, and the other is external angle plastic surgery. The adaptation scope of these two kinds of open-angle plastic surgery is different, so we should choose the operation method according to our own situation. Inner canthoplasty is also called correction of epicanthus, and epicanthus refers to the vertical skin fold in front of the inner canthus. Covers the corner of the eye, making it smaller than people without epicanthus, and at the same time blocking part of the field of vision, so that people with double eyelids can only form "half pairs", which affects the beauty of the eyes. Epicanthal epicanthus is very common among oriental nationalities. The "trick" of inner/outer canthus plastic surgery lies in the use of non-invasive imported instruments and fine suture after canthus plastic surgery-because of the special position of canthus, there are many tissue injuries during canthus plastic surgery, and the suture after canthus plastic surgery is not fine enough, which is easy to leave scars. According to your personal characteristics, choose the appropriate amount of epicanthus excision, avoid the eye plastic effect is not obvious or eyelid ectropion, and make your eyes bigger perfectly without anyone knowing. Whether the canthus opening is successful or not, it is the key to choose a regular plastic surgery hospital first, and then the doctor's technical level and postoperative self-care are very important.
