Cosmetic Skin Suture and Irregular Skin Wound Suture

Skin scars cannot be avoided, but its degree is closely related to the shape of the incision, local tension, blood supply, and other factors. In this chapter, we focus on the structure of the skin and the concept of relaxed skin tension line (RSTL). Through a detailed discussion of the tissue structure involved in suturing and the local tension of the incision, we try to make readers understand: (1) Influence of different tissue structures on the appearance of the incision after suturing; (2) Characteristics of local blood supply; (3) The distribution of human skin tension, so as to design the surgical incision and adjust the shape of the wound edge in irregular wound suture.
