Surgical method for correcting epicanthus: 1. Mild epicanthus: for patients with mild epicanthus who seek medical treatment simply for beauty, local single Z plasty is often used. Design a Z-shaped incision in the inner canthus under local anesthesia. After local release, the flap was exchanged to eliminate epicanthus, and the wound was sutured intermittently after hemostasis. Second, the more serious the epicanthus is, the more complicated multi-flap plasty is needed for epicanthus, and the accompanying deformity can be repaired at the same time. After this operation, the scar on the inner canthus is obvious, which is not suitable for patients with mild epicanthus with simple aesthetic requirements.
