In the lower right quadrant of the anterior abdominal wall, demonstrate the fatty (Camper's fascia) and membranous (Scarpa's fascia) layers of the superficial fascia. The membranous layer is deeper and is adjacent to the deep fascia of the anterior abdominal wall.

1. Use scissors to blunt dissect between the deep membranous layer of the superficial fascia (Scarpa's fascia) and the deep fascia overlying the external oblique muscle. Start laterally at the level of the umbilicus and use your scissors and fingers to separate the two layers. Use a scalpel to cut any intervening nerves, vessels or scar tissue.
2. Reflect the superficial fascia towards the thigh leaving it attached at the inguinal ligament.
3. The superficial surface of the flap is the fatty layer (Camper's fascia) and the deep surface of the flap is the membranous layer (Scarpa's fascia).
