AbstractIn select cases, to prevent any functional loss and to initiate early function during the early burn period, the reconstructive procedure of choice may be flap coverage. In these circumstances, when the ideal flap donor site is burned, the clinician may be hesitant to raise this flap because of questionable flap survival. The authors conducted this study to determine whether a superficially or deeply burned skin island flap would survive when elevated during the early postburn period. If these flaps are usable, they could expand the options available for burn wound coverage. They used a rat epigastric island flap model, and divided 50 study animals into two groups. In group 1 (N = 25), the right epigastric flap site was burned superficially and the left side was left uninjured. Island flaps were raised on both sides 4 days after the burn injury. The flaps were then sutured back into their original sites, and were evaluated 5 days after the surgery. In group 2 (N = 25), the right epigastric flap site was burned deeply and the left side was left uninjured. Island flaps were raised 4 days after the burn injury on both sides, as in group 1. The flaps were then sutured back into place and were evaluated 5 days after the surgery. All of the control flaps on the rats' left sides survived in both groups. In addition, all the superficially burned flaps survived in group 1 (100%), and 21 of the deeply burned flaps survived in group 2 (84%). There was no significant difference between superficially and deeply burned flaps with regard to survival, and the burned flaps were as successful as the unburned control flaps in both groups (p = 0.11). Skin island flaps elevated after superficial or deep burn injury are reliable in this animal model.
