Fleur de lis or corset abdominoplasty techniques are sometimes used interchangeably for a procedure that has an inverted "T" scar. However, there are surgeons who use the term corset to mean and incision with an incision along the upper abdomen as well (under the breasts), creating a sideways "H" incision. There are also techniques that use 2 flank incisions to tighten the abdominal skin. The scar pattern required depends on your body shape, where the excess skin is located and how your surgeon anticipates redraping the skin. It is not a one size fits all technique. Typically, these extended skin removal operations are performed in patients who have had significant weight loss due to the trade off between a worse scar pattern, for more tightening. Your best bet is to see a board certified plastic surgeon and discuss the various benefits/trade offs of different scar patterns. Once the incisions have been made, there is no way to remove the scars, so it's important to have this discussion preoperatively with a surgeon who has experience with varying techniques.
