The superficial fascia as a new plane of elevation for anterolateral thigh flaps.

The elevation plane for the anterolateral thigh perforator flap is either subfascial or suprafascial approach. But extensive debulking is frequently performed with possibilities of endangering viability. We hypothesized that by elevating the flap in the layer between the deep and the superficial fat, the superficial fascia, we will be able to achieve elevation of a thin and hemodynamically reliable flap without wasting human tissue. This approach was performed on 54 cases. The average weight was 68.1 kg, and average body mass index was 24.6 kg/m. Primary closure was performed on 18 cases and skin grafts on 36 cases. Evaluation for flap survival, contour of the flap, and donor site were performed. All 54 flaps were successfully elevated with at least one viable perforator with this approach. Total flap loss was noted in 1 case, resulting in a 98% survival rate. Secondary debulking was performed on 3 cases whose body mass index was >29. Regarding donor site, the primarily closed sites showed no complications, and the grafted skin over the deep fat leads to similar contour compared with the contralateral side. The study shows that this new plane can be used as a level of elevation while acting as a guide to promise adequate blood supply based on the subdermal plexus.
