Wound healing poses a variety of challenges making it a vital subject in medicine. With the advancement of science, we have seen the use of a new xenograft known as acellular fish skin (AFS) grafts that are derived from either Atlantic cod or Nile Tilapia. Fish skin has shown anti-inflammatory and anti-bacterial properties that support and improve wound healing in a variety of wounds including burns and diabetic foot ulcers (DFU). There is ongoing research that evaluates the efficacy of fish skin grafts in comparison to alternative wound healing techniques. A literature search was conducted through the National Library of Medicine with search terms fish skin graft, AFS, xenograft, dehydrated human amnion/chorion, ulcer, burns, and wounds. A total of ten studies that investigate the efficacy of fish skin grafts either in comparison to a different wound healing technique or by simply observing wound healing with fish skin grafts and recording the results were chosen. AFS showed superior healing in comparison to collagen alginate dressings, silver sulfadiazine cream 1%, and allografts. Although there is no one specific gold standard technique for wound healing, fish skin grafts demonstrated overall improved and quicker wound healing, fewer dressing changes, less pain, and lower costs.
