You may have noticed that, despite diet and exercise, the fat on your flanks doesn't disappear easily. This accumulation of fat and skin in the hip and lower back area can significantly alter your silhouette, making your waist less defined and your buttocks appear less lifted.
Flankplasty is a cosmetic body contouring surgery designed to reshape this area by removing excess skin and accumulated fat. In many cases, it can also naturally enhance the shape of the buttocks. If you're looking for a more defined and harmonious figure, this guide explains everything you need to know about this procedure.
What is flancoplasty and what is it used for?
Flankplasty, also known as trunkplasty, is a cosmetic surgery aimed at removing excess skin and fat located in the flanks, that is, on the sides of the waist and in the lumbosacral region or lower back.
This procedure allows you to:
- Reduce localized fat in the hip and lower back area.
- Eliminate sagging caused by aging, pregnancy or weight loss.
- Improve waist definition.
- Achieve a more balanced and streamlined silhouette.
- Promote a slight lifting of the buttocks by tightening the skin in the area.

Difference between flankplasty and liposuction
Although both procedures can treat the flank area, they are not the same.

Its objective is not only to reduce volume, but also to tighten the area and redefine the body contour. Therefore, it is often recommended for postpartum patients or those who have experienced significant weight loss.
La liposuctionIn contrast, it focuses on removing localized fat. It's a good option when the skin retains adequate elasticity and there's no significant excess skin. It allows for volume reduction, but doesn't offer the same firming effect as flank lifts.

How is a flankplasty performed?
Preoperative
Before the procedure, a complete medical evaluation is performed, including medical history, physical examination, tests, and surgical planning. Photographs and measurements are also typically taken to design the treatment based on each patient's anatomy. In addition, it is common to recommend quitting smoking and avoiding certain medications before surgery.
During surgery
The procedure is performed under general or epidural anesthesia, depending on the case. The incisions are usually placed along the bikini line or in the lower back to be as discreet as possible. Through these incisions, excess skin and fat are removed, the area is tightened, and the waist is redefined. In some cases, this tightening also helps to slightly lift the buttocks.
The duration depends on the complexity of the case and whether it is combined with other procedures, such as a tummy tuck.
Combined techniques
Flankplasty can be combined with other body contouring procedures. The most common combinations include:
- Abdominoflancoplasty: flankplasty plus abdominal surgery to improve the entire midsection.
- Cruroflancoplasty: combination with thigh lift.
- BBL: fat grafting to the buttocks to increase volume and projection, known as Brazilian Butt Lift.
Flankplasty and BBL: an increasingly popular combination
Many patients combine flank lifts with a Brazilian butt lift (BBL) to achieve a more complete body contouring transformation. In these cases, the fat extracted from the flanks can be purified and used to add volume and shape to the buttocks.
This combination allows you to work on two objectives simultaneously: slimming the waist and improving the projection of the buttocks. The result is usually a more harmonious figure, with a smoother transition between waist, hips, and buttocks.
