Use of Dermal Regenerative Templates for Burns

Abstract

Autologous skin grafting has permitted survival and restoration of function in burn injuries of ever larger total body surface area (TBSA) sizes. However, the goal of replacing "like with like" skin structures is often impossible because full-thickness donor harvesting requires primary closure at the donor site for it to heal. Split-thickness skin grafting (STSG), on the other hand, only harvests part of the dermis at the donor site, allowing it to re-epithelialize on its own. The development of the first dermal regenerative template (DRT) in the late 1970s represented a major advance in tissue engineering that addresses the issue of insufficient dermal replacement when STSGs are applied to the full-thickness defect. This review aims to provide an overview of currently available DRTs in burn management from a clinician's perspective. It focuses on the main strengths and pitfalls of each product and provides clinical pearls based on clinical experience and evidence.
