Extended myofascial thigh flaps for repair of large full-thickness abdominal wall defects.

The large, full-thickness abdominal wall defect encompassing the upper and lower quadrants can test the surgeon's ingenuity in providing definitive repair. Two cases are reported of this type of abdominal wall defect closed in one stage using an extended tensor fascia lata myofasciocutaneous flap and an extended rectus femoris myofascial flap, respectively. In addition, a fresh cadaver dye injection study demonstrates the extensive circulatory pattern of these flaps.
