Application of 3 Different Types of Pedicled Adipofascial Flaps in the Repair of Deep Dead Space Wounds

Abstract

Introduction. Dead space is an important risk factor for poor wound healing; therefore, it is important to effectively fill deep dead space through individualized tissue flap design during the repair of complex wounds. Adipofascial flaps have yielded good results in the repair of deep dead space wounds. Objective. The authors evaluated the efficacy of 3 kinds of adipofascial flaps to repair deep dead space wounds. Methods. From January 2019 to January 2022, 15 patients with complicated wounds accompanied by deep dead space underwent repair via 1 of 3 kinds of adipofascial flaps, and the clinical efficacy was observed. Results. All 15 transplanted adipofascial flaps exhibited complete survival, and within a mean follow-up of 14.7 months, both the donor and recipient sites had successfully healed. Conclusion. The traditional pedicled adipofascial flap was used to repair single deep dead space wounds, and pedicled perforator adipofascial extension flaps or layered fasciocutaneous flaps were used on compound tissue defect wounds, thus providing a relatively simple, safe, and effective method to repair a small area of tissue defect with deep dead space wounds.
