If you’ve been diagnosed with breast cancer and are considering autologous breast reconstruction, the PAP (profunda artery perforator) and SGAP (superior gluteal artery perforator) flaps might be ideal solutions, especially if you’re not a candidate for abdominal-based flaps like the DIEP. These techniques use tissue from the upper thighs or buttocks, offering natural-looking results without implants and without impacting your core strength.
At New York Group for Plastic Surgery, we specialize in reconstructive options that not only restore your body after a mastectomy but also enhance your shape in the process. In this article, we explore the unique body contouring benefits of PAP and SGAP flap procedures.
What are PAP and SGAP flaps?
PAP and SGAP flaps are forms of autologous breast reconstruction, meaning your own tissue is used to create a new breast mound after mastectomy. These are “free flap” procedures, where skin and fat (but not muscle) are taken from one area of the body, completely detached, and then microsurgically reconnected to blood vessels in the chest.
- PAP flap: The PAP flap harvests skin and fat from the inner upper thighs, just beneath the buttock crease, to reconstruct a natural-looking breast. This technique spares all muscle, preserving thigh strength and mobility.
- SGAP flap: The SGAP flap removes skin and fat from the upper buttocks without disturbing the gluteal muscles. It offers a natural, soft breast reconstruction and is particularly beneficial for patients who cannot use abdominal tissue.
Body contouring benefits of PAP and SGAP flaps
Slimmer, more defined inner thighs
The PAP flap harvests tissue from the upper inner thigh, which is a common area where stubborn fat tends to accumulate, especially in women. By removing this tissue, the procedure slims and contours your inner thighs, similar to the effect of a targeted liposuction or medial thigh lift. For many women, this reshaping improves comfort when walking, eliminates chafing, and enhances thigh definition.
Lifted, firmer appearance of the upper buttocks
SGAP flap procedures draw fat and skin from the upper gluteal region, which not only supplies tissue for your new breast but also lifts and reshapes the buttocks. As tissue is strategically removed, the procedure creates a natural lift effect, similar to that of a butt lift. Women often notice a firmer, more sculpted silhouette from the waist down, which improves how clothing fits and boosts body confidence.
No damage to abdominal muscles or core structure
Unlike abdominal flap procedures such as TRAM or DIEP, PAP and SGAP flaps completely avoid the abdominal region. This means your core muscles remain untouched, which preserves abdominal strength and reduces the risk of hernia, bulging, or weakness in your midsection. For active individuals or those with a history of abdominal surgery or hernia, this contributes to a smoother recovery.
Balanced body proportions after mastectomy
One of the lesser-discussed aspects of autologous flap reconstruction is the opportunity to restore symmetry and balance to your overall figure. When tissue is removed from the thighs or buttocks and used to rebuild the breast, it not only creates a natural-feeling breast but also redistributes volume in a way that enhances harmony between your upper and lower body. Our surgeons pay close attention to your proportions, ensuring the final result complements your natural shape and enhances confidence both in and out of clothing.
Lasting results without implants or synthetic materials
Another advantage of PAP and SGAP flaps for body contouring is their long-term durability. Because your own living tissue is used, your reconstructed breast will age naturally with you, maintaining a soft, lifelike feel. There’s no risk of implant rupture, capsular contracture, or the need for future replacement surgeries. Additionally, fat redistribution often makes the donor area (thighs or buttocks) appear more toned or sculpted. It’s a win-win: enhanced breast volume and reshaped donor sites in one comprehensive procedure.
Improved emotional and physical confidence
Beyond the visible contouring benefits, PAP and SGAP flap reconstruction can offer a powerful emotional transformation. By combining breast reconstruction with aesthetic improvements in other areas of the body, you may feel more empowered, feminine, and complete after cancer treatment. Patients at New York Group for Plastic Surgery frequently report increased body positivity, reduced self-consciousness, and greater ease wearing a wider range of clothing.
