  • Publication number: 20240226385
    Abstract: The present invention relates to an acellular skin substitute for breast reconstruction and a preparation method therefor. In the present invention, an acellular skin substitute may be prepared through the removal of epidermal layers and an acellularization process, in which the use of a proteolytic enzyme and a surfactant is excluded. In addition, since the acellular skin substitute is cut into suitable sizes and shapes to cover a breast reconstruction implant through design software and then cut out with a CNC machine, the time for breast reconstruction surgery may be reduced, and since no dead space is formed after suturing, the incidence of seromas may be reduced. Accordingly, the side effects of surgery may be lessened.
