Biodegradable temporizing matrix utilization on a pediatric burn following an exploratory laparotomy

Abstract

Biodegradable temporizing matrix (BTM) is a synthetic polymer used to promote new tissue growth in full-thickness wounds by providing a framework for additional tissue coverage of a new fascial closure, demonstrating its potential for use in recent incision closure and wound healing. While a case study on a pediatric patient with deep soft tissue friction burns exists, there are no reports on BTM utilization immediately following the closure of a surgical excision. This case report describes the successful use of BTM in promoting wound healing and skin graft incorporation in a 19-month-old female patient with severe scalding burns and a recent exploratory laparotomy. Following an excision of the burn wounds and closure of the surgical incision, BTM was secured over the incision site, and a split-thickness skin graft was applied using the RECELL system. Despite the initially limited blood flow around the incision, the BTM facilitated additional tissue coverage of a new fascial abdominal closure and vascularization, thus enabling successful graft incorporation and incision healing. This case highlights the untapped potential of BTM in supporting wound healing and skin grafting over recently closed incisions, expanding its application beyond traditional use in full-thickness wounds.
