Abdominoplasty (tummy tuck) is a common cosmetic operation. One of the risks of surgery is delayed wound healing caused by impaired circulation to the skin. In an effort to reduce risk, some investigators1 advocate a limited-undermining technique, with preservation of the perforating blood vessels and preservation of the Scarpa fascia of the lower abdomen. However, there is no evidence that this limited-undermining technique improves blood supply compared with a traditional abdominoplasty dissection. Such a limited dissection may compromise the cosmetic result.
