Flap Reconstruction and Epifast in Burn Wound Management: A Narrative Review with Illustrative Cases

Burn wound reconstruction spans two largely distinct clinical problems: full-thickness injuries with exposed critical structures that require flap coverage, and superficial partial-thickness wounds for which biologic dressings can accelerate healing without donor-site morbidity. This review summarizes contemporary evidence on free and pedicled flap reconstruction in acute and delayed burn care and on Epifast®, a cryopreserved allogeneic keratinocyte graft used for first- and second-degree burns, and situates that evidence alongside two illustrative intraoperative photographs from the authors’ own practice: a flap reconstruction case and an Epifast-treated wound. Across the reviewed literature, free flap loss in the acute burn setting (approximately 9.9–10%) remains considerably higher than in elective reconstruction (2–5%), while pedicled and delayed free flaps achieve markedly lower loss rates. Epifast has shown consistently favorable outcomes in small case series, particularly in pediatric and anatomically sensitive burns, though the evidence base remains limited to case series and reports. Flap surgery and cultured epidermal allografts should be viewed as complementary rather than competing tools in the reconstructive burn surgeon’s armamentarium.
