Functional Panniculectomy / Abdominal Apron Removal | Incisions, belly button and combined surgery

Standing assessment lets gravity show how far the pannus hangs, so the surgeon can estimate reasonable skin removal. The midline is marked, a line connects the suprapubic region to the hips, and the superior mark is drawn where the abdomen overlaps the pubis, connecting to the hip incision. In extreme cases, alternative superior resection limits may be drawn and the final excision adapted during surgery to balance maximal tissue removal with flap tension, tissue viability and wound-complication risk. The goal is to remove hanging skin and fat from the lower abdomen for a smoother contour, without tightening abdominal muscles. This is not a cosmetic tummy tuck.

Panniculectomy removes hanging skin and fat from the lower abdomen to create a smoother contour; it usually does not tighten abdominal muscles. The long lower-abdominal scar typically runs across the lower abdomen from hip to hip, just above the pubic area, and may be linear or T-shaped with a fleur-de-lis incision. The inferior incision is often placed in or slightly above the lower abdominal crease to allow closure with minimal tension and dead space. If there is much side skin, an up-and-down incision may be added, and the belly button may need repositioning. Scar shape and length vary with pannus size and shape, so no single scar position fits everyone.

Panniculectomy removes the lower abdominal skin and fat apron through a horizontal incision. If excess skin extends laterally, a vertical incision may be used; a fleur-de-lis design can improve lateral contouring, but it leaves a long vertical midline scar extending toward the xiphoid and has limited blood supply at the flap junction. Vertical excision is performed first to avoid over-resection, and lateral undermining is minimized to preserve blood supply. This is especially useful after massive weight loss, when both horizontal and vertical excess are present. The horizontal incision remains the base; the vertical addition is chosen for side-to-side skin excess, not for every patient. Your surgeon will mark the pattern based on your skin distribution.

Panniculectomy removes excess lower abdominal skin and fat, while hernia repair addresses a weakness in the abdominal wall. Evidence describes panniculectomy as a good procedure to pair with incisional hernia repair because the operative fields can remain distinct, limiting dead space and communication of complications. Concurrent pannus removal may reduce tension on the hernia repair and the burden of ischemic fat and skin. Excess pannus may also contribute to seroma formation, so concurrent removal is being studied. However, simultaneous panniculectomy with components separation may increase wound-healing risks; one small series reported minor complications in 11 of 22 patients, most often skin necrosis or wound dehiscence. A CT scan may be used before surgery to confirm bowel position and avoid injury.

Panniculectomy removes hanging skin and fat; it does not usually tighten abdominal muscles. It can be paired with incisional hernia repair, keeping operative fields distinct and limiting dead space and communication of complications. Simultaneous components separation may improve appearance but increases wound-healing problems; one small series reported minor complications in 11 of 22 patients. If midline fascial closure is not achieved, mesh may bridge the defect with at least 5 cm overlap; bridging repairs are weaker and carry hernia recurrence risk. Panniculectomy with mesh repair has higher wound morbidity and possible mesh infection, so true panniculectomy can be deferred until mesh repair heals. This is why staging and coordination matter.

Panniculectomy is designed for symptomatic skin excess when you cannot safely tolerate the healing that undermining and abdominal wall plication require. It is a functional, reconstructive procedure: skin flap undermining is limited and no plication is performed, so risks of traditional abdominoplasty are minimized. Abdominoplasty is traditionally aesthetic and includes skin and fat removal plus abdominal wall tightening and umbilical repositioning, usually when you are at or near goal weight. If excess extends laterally or posteriorly, neither procedure addresses those areas; conversion to a lower body lift, liposuction or belt lipectomy may be discussed with your surgeon before your surgery.

Panniculectomy removes symptomatic excess skin and fat, often in people who may not tolerate undermining and abdominal wall tightening. Significant scars can compromise healing, so the surgeon watches for latent hernias and large, dilated, high-pressure vessels, using an automatic clip applicator to ligate veins and arteries. Dissection goes straight to the abdominal wall; the upper incision is perpendicular to skin and the lower more oblique, limiting dead space. Hemostasis is checked with normalized blood pressure, and resection stays conservative to avoid tension and dead space. Drains are placed, and smoking cessation matters because smoking affects wound healing and blood supply.

Progressive-tension sutures attach the abdominal flap to underlying fascia, advancing it and distributing tension while minimizing dead space; this can reduce seroma formation. Drains remove fluid and help tissue surfaces adhere, but closed suction drains carry less retrograde infection risk than passive drains. The choice depends on dead space, tissue quality and surgeon preference; no single method is guaranteed. This evidence comes mainly from abdominoplasty and body-contouring sources, not a universal panniculectomy protocol. If fluid accumulation is a concern, your surgeon may still use drains. Seroma means fluid collecting under the skin; drains are usually removed when output decreases and healing is checked.

Risk rises when BMI is high, diabetes is uncontrolled, nutrition is poor, smoking continues, or hernia or prior abdominal surgery affects tissue quality. One case report also linked higher complication risk with older age, male sex and larger resected tissue amounts. Surgeons therefore plan conservative resection, avoid tension and dead space, assess hernia or rash concerns, and consider VTE prophylaxis. DVT risk may be assessed with the Caprini score, and anesthesia and medicine clearance may be warranted for super-obese patients. Larger patients can hide hematomas or seromas, so symptomatic concerns may need ultrasound or CT investigation. Care must be intensive, with a low threshold for reassessment if concerns arise.
