In this case, if it is a local knife cut, the asymmetry after suture is generally caused by irregular incision or local skin defect. If there is no skin defect, it should be symmetrical after suture.

Suggestion:

It is suggested to apply drugs such as basil locally to reduce scar irritation and hyperplasia for a period of time. If the edema completely subsides and there is obvious asymmetry, plastic surgery can be done again.
