Treatment of Large Scars in Children Using Artificial Dermis and Scalp Skin Grafting

Background and Objectives: Large scars formed after burns injury can seriously hamper appearance and function in children. Surgical resection of scars and secondary skin or flap grafting often brings severe damages to donor sites, which may lead to physiological and psychological development disorders in children. Here, we introduce the use of artificial dermis and skin grafts from scalps to treat large scars in children to minimize the donor site morbidity. Methods: A retrospective char review was performed including 7 children with large scars between January 2016 and December 2017. First, the scars were resected, and artificial dermis was applied to the secondary wounds. Twelve days later, outer silicone membrane was removed. Another 2 days later, scalp skin grafts of 0.3 mm were transplanted to the wounds. Manchester Scar Scale and Visual Analog Scale were used to evaluate scar appearance before and after the treatment respectively. One special patient with extensive scars was treated twice at an interval of 1 year. The first therapy was performed with both conventional method of resection and skin grafting and the new method described above. In the second therapy, 4 samples were taken from 4 different sites—the normal skin, scars, the skin where artificial dermis and scalp skin grafting were performed, and the skin where only scalp skin grafting was performed. H-E staining, Masson staining, Aldehyde fuchsin staining, and scanning electron microscopy were used fo...
