Usage of intermingled skin allografts and autografts in a senior patient with major burn injury. (a) The patient was accidentally burned by gas flame, resulting in a major burn injury covering 80% of her TBSA. Most of the them were third-degree burn wounds. (b) In the eighth week after the injury, the wounds were covered with intermingled skin allografts and autografts. (c) The autografts and fresh allografts expanded and the cryopreserved allografts necrotized and fed off gradually from the edge to the center. There was no obvious wound exposure during the entire treatment process. (d)-(h) After a year of follow-up, the patient recovered well and regained satisfactory function.

About 80% of the total body surface area (TBSA) was burned, most of them were third-degree burns (Figure 1a). This time we covered the wounds with intermingled skin allografts and autografts (Figure 1b): small skin autografts (0.5 cm x 0.5 cm) + moderate close relative's fresh allografts (1 cm x 1 cm) + large cryopreserved allografts (2 cm x 2 cm). The autografts and fresh allografts expanded and the cryopreserved allografts necrotized and fed off gradually from the edge to the center (Figure 1c). After a year of follow-up, the patient recovered well and regained satisfactory function (Figure 1d-h).
