Schematic drawing of the superficial inferior epigastric fascia (SIEF) flap harvest.

Depicted is the elevation of the flap from distal to proximal (A), providing a 4 × 3 cm adipofascial flap (B) with lateral branch of the superficial inferior (SIE) vessels. The SIEF flap was tunneled subcutaneously toward the nerve without vascular twisting of the epigastric trunk (C) and wrapped around the nerve graft reaching both anastomoses (D). The flap edges were trimmed if needed and two 10-0 nylon sutures were placed to secure the position of the SIEF flap (E). With permission of the Mayo Foundation, Copyright Mayo Foundation 2019.
