Pediatric facial skin soft tissue defects are often caused by tumor or scar excision, trauma, and infection. The most common cause is giant nevus. Since the trauma cannot be closed directly after complete excision of the lesion, skin grafting is needed to repair it, and the difficulty of repairing such trauma is often not in the trauma coverage, but in the cosmetic effect of reconstruction. For facial wounds that can be repaired with a local flap, a reasonable application of the flap can achieve a cosmetic reconstruction effect. This not only requires the operator to be familiar with facial anatomy, tissue structure characteristics, and aesthetic unit division, but also requires good aesthetic literacy, rich imagination, and skillful operating techniques. Pediatric skin has its own characteristics, which makes it suitable for early surgical repair, the flap is more likely to survive, and the younger the age, the less obvious the scar. The earlier the flap is done, the smaller the lesion will be and the smaller the scar will be than when it is older. The selection and design of the ideal flap is the most challenging and imaginative aspect of local flap grafting. In the selection and design of local flaps, our experience is that: 1. First, the situation around the trauma needs to be examined to determine whether there is enough local skin available to design a local flap, whether direct closure of the secondary defect after flap transfer will cause displacement of important anatomical structures, and whether it will affect function. 2.The area with the closest skin color, texture, thickness, striae, hair, etc. to the recipient area should be selected as the flap donor area, and the additional incision line and the final local scar line should be hidden in wrinkles, facial aesthetic unit demarcation lines or other areas that are not easily detected. 3.Different trauma form and site, different local flaps are selected. Even if the trauma form and site are exactly the same, for different patients, different flaps may be selected and designed due to the differences in their skin elasticity and looseness. 4.Follow the principle of partial facial repair to select and design flaps. 5, the facial skin is rich in blood circulation, the local flap design has greater flexibility in the length to width ratio, 3 to 4:1 generally does not occur when the blood circulation is impaired.
