Fractional epidermal skin grafting

Skin grafts can be obtained from several sources, both human and animal. Skin grafts can include all or a portion of the skin, including the epidermis and dermis.1 More recently, the use of skin substitutes, dermal fillers and tissue expanders has increased surgeons’ and dermatologists’ ability to cover skin defects resulting from burns, traumatic injury, chronic wounds or excision of cancerous lesions.2 The major sources of skin grafts are autografts, homografts and xenografts. Skin substitutes, dermal fillers and tissue expanders provide additional dermal or epidermal components (or both) for wound coverage and in order to stimulate wound healing.
