Many clinical wounds, including some deep burn wounds, can eventually be repaired only through surgery after a period of dressing changes. One of the more common surgical procedures is skin grafting. There are many patients who feel the sky is falling when they hear doctors say they need skin grafting, and always think that skin grafting is a very scary surgery. Here is a layman’s explanation for you. There are 3 types of implants, and according to the thickness of the skin, they are divided into full-thickness skin, medium-thickness skin and edge-thickness skin. As the name suggests, full-thickness skin means that the whole layer of skin is taken off and transplanted to other places, that is, “tearing down the east wall to make up for the west wall”. What about the missing piece of the eastern wall? It is necessary to take an edge thick skin graft in another place to “east wall” to repair it. So, how thick is the thick skin? In fact, the thickness of the skin is usually less than 0.3 mm, for example, the wound caused by taking a small piece of thick skin is equivalent to accidentally rubbing a piece of skin on the leg. Therefore, this surgical solution is a kind of “borrowing the east wall to repair the west wall, and the east wall will be fine after the west wall is repaired”. Because of this advantage, the thick-skinned implant is the most used in skin grafting surgery. Of course, there are advantages and disadvantages of thin skin and thick skin. Thick skin usually has less scars, better appearance and wear resistance after transplantation, but thick skin requires better wound substrate conditions for survival, and the area where the skin is taken needs to be repaired with additional skin implants. Thin skin is easier to survive, and the area where the skin is taken can heal on its own, but the skin graft has a poorer appearance and is not abrasion resistant. Therefore, areas that are subject to more pressure and friction are generally not suitable for the use of thick-edged skin implants. However, with the advancement of technology and the use of new materials, blade-thickness skin grafting is gradually overcoming its disadvantages. For example, composite grafting of matrix components and blade-thickness skin on the traumatized surface has shown remarkable results! After reading these introductions, do you still feel that skin grafting is scary?
