Plastic surgery experts say that in a regular plastic surgery institution, canthotomy will generally not have sequelae. On the contrary, if you are greedy for petty gain or look for a plastic surgery hospital casually, the safety after canthotomy is uncertain. Let's take a look at what the experts told us about the risks of canthotomy and how to avoid them: 1. Because of the fine anatomical structure of the inner canthus, if you are not familiar with it, you may be careless. 2. If there are slight surgical traces in the place where there have been Mongolian wrinkles, experts do not recommend that you choose to do canthus surgery; 3. If the canthus opening is not done well, it may leave traces after the operation, so you must choose an experienced expert for the operation. Because experienced experts are skilled in anatomy and related ophthalmology knowledge, they will avoid the sequelae of canthus opening and make the effect of canthus opening reach the best state. 4. It is not advisable to overuse eyes and prevent ocular inflammation in the short term after external canthus surgery, otherwise it will cause adhesion of new wound site and affect the surgical effect of external canthus.
