The authors present their experience with a previously described but infrequently used variation of the rectus abdominis myocutaneous flap. Skin paddles angled obliquely from the line of the rectus abdominis and toward the rib cage were successfully carried on periumbilical perforators from the inferior epigastric system. Skin paddle dimensions ranged from 6.5 to 12 cm in width and from 10 to 27 cm in length in 14 consecutive patients. In six of the 14 patients, the flap was used intraabdominally to obliterate radiated pelvic defects and to close radiated vaginal defects. Five flaps were placed externally to repair radiated wounds of the perineum, thigh, and trunk, and the remaining three cases were performed as free tissue transfers. One cadaver injection study was performed to redemonstrate the preferential flow of fluid in a superior-oblique direction from periumbilical perforators. Termed the oblique rectus abdominis musculocutaneous ("ORAM") flap, this flap variation has significant advantages in terms of ease of dissection and versatility over its flap cousins the vertical rectus abdominis musculocutaneous flap and the transverse rectus abdominis musculocutaneous flap.
