The aim of this study was to describe the scheme, surgical procedures, and clinical outcomes for the early repair of deep wounds of the posterior talocrural region in extensively burned patients with a method combining a superficial temporal fascia free flap with thin split-skin grafting.From January 2013 to February 2016, 9 extensively burned patients with deep tissue defects of the posterior talocrural region were treated in our department (2 patients had bilateral deep tissue defects of the posterior talocrural region). All 11 wounds were repaired using a superficial temporal fascia free flap and thin split-skin grafting. After the operation, survival of the fascia flaps and grafted skin was observed, and the appearance and functional recovery of the grafts were evaluated. Follow-up information was reviewed, and complications were documented.All 11 fascia flaps survived completely. Two cases of partial skin necrosis healed after the second application of skin grafts. The appearance and function of recipient sites were well restored in all patients over a follow-up period of 5 to 14 months.Deep tissue defects of the posterior talocrural region can be effectively repaired with our method combining a superficial temporal fascia free flap with thin split-skin grafting. This method offers the advantages of a good appearance, strong resistance to infection, minimal damage at the donor site, short course of disease, and good prognosis.
