Beyond the "Standard" Options: Advanced Microsurgery in the West Valley

For many women facing breast reconstruction, the conversation begins and unfortunately ends with the DIEP flap. While the Deep Inferior Epigastric Perforator (DIEP) flap is the gold standard for using abdominal tissue to rebuild the breast, it relies on a specific donor site: the belly. But what if you are naturally lean? What if you are an athlete with no "pinchable" fat on your stomach? Or what if you have already had a tummy tuck?

At Southwest Breast & Aesthetics, we believe your anatomy should not limit your access to autologous reconstruction. When the abdomen is not an option, we turn to the S-GAP flap, the Superior Gluteal Artery Perforator flap. This sophisticated surgical procedure uses tissue from the upper buttock to create a soft, warm, living breast. We are among the few plastic surgeons in the Phoenix area, and indeed the country, with the extensive experience required to perform these complex flap reconstruction procedures. We bring this level of microsurgical breast reconstruction directly to our Peoria office, ensuring that women in the West Valley have access to every biological option available to restore their breasts.

What Is the S-GAP Flap?

The S-GAP flap is a muscle-sparing technique that harvests skin and fat from the upper gluteal region to build a breast mound.

The Name: S-GAP stands for Superior Gluteal Artery Perforator.
The Technique: Unlike older gluteal flaps that sacrificed the gluteus maximus muscle (leading to walking difficulties), the S-GAP is a true perforator flap. We carefully dissect the blood vessels that travel through the muscle without cutting the muscle fibers themselves.
The Result: We transfer this harvested tissue to the chest and reconnect the tiny blood vessels to the internal mammary system under a microscope. This restores blood flow instantly, keeping the tissue alive permanently.

This procedure allows us to use your own body to create a natural look and feel, completely avoiding the need for breast implants or the lifelong maintenance of foreign devices.

Am I a Candidate for S-GAP?

The S-GAP is typically a "Plan B" or "Plan C" for patients who cannot undergo a DIEP flap. You might be an ideal candidate if:

You lack abdominal tissue: You are too thin for a DIEP flap or have previously had an abdominoplasty.
You have "shelf" tissue: You have excess tissue in the upper hip/buttock area.
You want to avoid implants: You desire a permanent, natural tissue reconstruction.

During your private consultation at our Peoria clinic, our reconstructive surgeon will evaluate your medical history and body habitus. We may also explore other innovative procedures if the S-GAP isn’t the right fit, such as the PAP flap (thigh), LAP flap (Lumbar Artery Perforator from the love handles), or the TUG flap (Transverse Upper Gracilis

The Microsurgical Advantage: Why It Matters

Flap surgery is not standard plastic surgery. It is microsurgery. It requires connecting blood vessels thinner than a strand of hair to ensure the blood supply is robust enough to keep the new breast alive.

At Southwest Breast, we operate with the highest volume and highest quality protocols. Our skilled hands are trained to handle the most challenging anatomical variances.

Vessel Matching: Gluteal vessels are often shorter than abdominal ones. We have the expertise to perform vein grafts if necessary to ensure a tension-free connection.
Sensory Potential: Because the gluteal tissue is rich in nerves, some patients experience a return of sensation in the reconstructed breast over time.
Complex Cases: We regularly perform breast revision surgeries, including breast implant removal and conversion to flaps for patients suffering from capsular contracture or implant illness.

The Procedure: What to Expect

S-GAP flap surgery is a major operation, typically lasting 6–10 hours. It is performed under general anesthesia at an accredited hospital.

Harvesting: We make an incision on the upper buttock, usually low enough to be hidden by standard underwear or bikini bottoms.
Transfer: The tissue is moved to the chest. If you are having a bilateral (double) reconstruction, we may take tissue from both sides.
Shaping: Gluteal fat is denser than abdominal fat, which often allows for greater projection. We shape it into a breast mound that mimics a youthful breast.
Closure: The donor site is closed, which results in a distinct contour improvement—essentially a "butt lift" effect.

Alternatives: PAP, LAP, and Stacked Flaps

If the upper buttock is not suitable, we have other options.

PAP Flap (Profunda Artery Perforator): Uses tissue from the inner thigh. This is excellent for small-to-moderate breast volumes and leaves a scar hidden in the groin crease.
LAP Flap: Uses tissue from the lumbar region (lower back/love handles).
Composite Stacked Flaps: For women who need more volume than one site can provide, we can "stack" multiple flaps (e.g., a DIEP and a PAP) to create a larger breast without implants.

We are a plastic and reconstructive practice that believes in a personalized approach. We do not force you into a single procedure; we tailor the treatment plan to your unique anatomy.

Recovery in Chandler

Recovering from sgap flap surgery requires patience.

Hospital Stay: Expect 3 to 5 days in the hospital for vascular monitoring.
Positioning: You will need to avoid putting direct pressure on the buttocks for the first few weeks. We will teach you specific sleeping and sitting positions.
Mobility: Because we spare the muscle, walking is encouraged early. However, strenuous lower-body exercise is restricted for 6–8 weeks.
Follow-Up: All post-op care is handled at our Peoria office. Our office staff will help coordinate your appointments and answer any questions.

Cost and Insurance

Reconstruction surgery after mastectomy is covered by federal law (WHCRA). This includes the S-GAP flap, hospitalization, and surgery on the opposite breast for symmetry (such as a breast lift, reduction, or breast augmentation). While we accept insurance, there may be out-of-pocket costs related to deductibles. We also work with financing partners to help patients manage expenses for cosmetic revisions or fat transfer procedures not covered by insurance.
