- Leno is 14-year-old boy suffering from Deep burns at his right anterior leg, affecting all layers of his skin even deeper tissues caused by electrical accident. His surgeon recommends skin grafting procedure as his medical-surgical intervention. The surgeon explained that they are going to perform full-thickness graft that involves removing or harvesting all the epidermis and dermis from the donor site that is usually taken from the abdomen, groin, forearm, or area above the clavicle. The small pieces of skin that is removed from the donor sites will be used to cover the burned area. Though Leno know that it is a safe surgical procedure, his insight on harvesting skin from other part of his body will create a new injury and might be his skin will no longer be the same again in terms of color and texture. Do You think Leno's insight is correct?
