Buried chip skin grafting for treatment of perianal burns

A technique of buried chip skin grafting for perianal burn injury is described. Small chip skin grafts are buried in the granulating wound around the anus and this procedure achieves epithelialization of the perianal and perineal wound within about 5 or 6 cm laterally from the middle with extremely small amounts of skin graft. Graft survival is not disturbed by stools or gently wiping of the wound to remove stools, as grafts are buried in the holes. If infection occurs soon after the operation, graft survival does not appear to be affected because the grafted holes show good drainage. This procedure is considered to be very useful for treating perianal or perineal granulating wounds in extensively and deeply burned patients who have limited autograft donor sites.
