epidermal substitutes
Manufactured skin products that replace the epidermal layer in burn reconstruction.
Full Definition
Epidermal substitutes are bioengineered products designed to replace the outer layer of skin in burn patients when autologous tissue is insufficient or unavailable. These products may be derived from cultured autologous keratinocytes, cultured allogeneic cells, or synthetic materials. Unlike dermal substitutes, epidermal substitutes specifically target the replacement of the epidermis and may be used alone or in combination with dermal replacement products. Common examples include cultured epithelial sheets and spray-on keratinocyte suspensions used in extensive burn injuries.
Usage
Usage note: Distinguish clearly from dermal substitutes and combination skin substitutes.
