Abstract:
Natural dermal matrix has good biocompatibility and can serve as " biological template" in wound repair. According to the source of material, natural dermal matrix can be divided into acellular dermal matrix (ADM), denatured dermal matrix, and scar dermal matrix. ADM is a biological material prepared by removing cellular components from the skin and retaining extracellular matrix (ECM) of the dermis. ADM possesses abundant natural biological information, low immunogenicity, and excellent regenerative capacity, which has greatly promoted the development of wound healing specialty as dermal substitute. Denatured dermis matrix is a layer of dermal tissue made by superficial tangential excision or dermabrasion on deeply burned wounds. The retained denatured dermis can recover gradually after transplantation of autologous skin on its surface, with similar structure, morphology, and biomechanics to healthy dermis. Scar dermal matrix is a kind of dermal scaffold made of autologous split-thickness scar tissue, possessing the characteristics of high survival rate, good texture, and slight scar reaction. Scar dermal matrix can effectively reduce secondary damage to the donor site when repairing scar contracture deformity. Based on the research progress at home and abroad and the opinions of domestic experts, this paper summarizes the indications, application methods, contraindications, and considerations of different types of natural dermal matrix in application of wound repair.
