    AbstractZ-plasty is a plastic surgery technique that is used to improve the functional and cosmetic appearance of scars. With this technique, it is possible to redirect a scar into better alignment with a natural skin fold or the lines of least skin tension. Contracted scars may be lengthened with this technique. Z-plasty involves the creation of two triangular flaps of equal dimension that are then transposed. Basic z-plasty flaps are created using an angle of 60 degrees on each side, which can lengthen a scar by 50 to 70 percent and reorient the direction of the central wound by 90 degrees. Keeping the length and angle of each flap precisely the same is key to avoiding mismatched flaps that may be difficult to close. Some possible complications of z-plasty include flap necrosis, hematoma formation under the flaps, wound infection, trapdoor effect, and sloughing of the flap caused by high wound tension.
