Dual-Vector Abdominoplasty. Combining Fleur de Lis Abdominoplasty with Upper Abdominal Lipectomy
Book Online NowPatients who have experienced significant weight loss often develop excess abdominal skin that cannot be adequately treated with a traditional abdominoplasty alone. In many cases, skin laxity exists in both vertical and horizontal directions and may extend into the upper abdomen and lower chest. These changes can persist despite stable weight and a healthy lifestyle because of a permanent loss of skin elasticity following major or massive weight loss.
Dual Vector Abdominoplasty is a surgical approach that combines a Fleur-de-Lis abdominoplasty with an upper abdominal lipectomy. This operation is intended for post-weight-loss patients with multi-directional abdominal skin excess, including persistent loose skin in the upper abdomen. The term “dual vector” reflects the use of two distinct directions of skin excision to treat complex anterior abdominal skin patterns.
Who May Be Suitable for Dual Vector Abdominoplasty
To understand who may be suitable for a Dual Vector Abdominoplasty, it is important to first understand how abdominal skin behaves during weight gain and weight loss. This operation focuses on the anterior abdomen, the area most affected by multidirectional skin stretch in patients with significant weight changes.
When a person gains a substantial amount of weight, the skin of the abdomen stretches to accommodate increased volume. Importantly, this stretching does not occur in a single direction. The skin expands vertically, horizontally, and, in some cases, obliquely, depending on body shape, fat distribution, and the duration of weight gain. Over time, the structural components of the skin are altered, resulting in reduced recoil once the excess weight is lost.
After major or massive weight loss, the underlying fat volume decreases, but the skin often fails to retract fully. This leads to persistent excess abdominal skin that may hang, fold, or bunch in multiple directions. While the lower abdomen is commonly affected, the upper abdomen and lower chest are less frequently discussed. In many post-weight-loss patients, skin beneath the rib cage and extending toward the lower chest becomes loose and redundant, contributing to an imbalance between the upper and lower abdomen.
Dual Vector Abdominoplasty may be considered for carefully selected patients who:
- Have excess abdominal skin affecting the anterior abdomen
- Demonstrate skin redundancy in both vertical and horizontal directions
- Have persistent loose skin in the upper abdomen or lower chest region
- Have achieved and maintained a stable weight after significant or massive weight loss
- Are medically fit for surgery
- Have realistic expectations regarding scarring, recovery, and outcomes
Suitability for this operation is determined during a personalised consultation, where anatomy, weight stability, medical history, and individual priorities are carefully assessed. Not all patients will be appropriate candidates, and alternative body-contouring procedures may be discussed as indicated.
Traditional Abdominoplasty: What It Can and Cannot Treat
A traditional abdominoplasty involves a horizontal incision across the lower abdomen, removal of excess skin, and tightening of the abdominal muscles when indicated. This approach primarily removes skin in a vertical direction and is most effective for patients whose excess skin is concentrated in the lower abdomen.
For patients with mild to moderate skin laxity, a traditional abdominoplasty can provide meaningful change. However, in patients who have experienced massive weight loss, this technique has limitations. It may not adequately treat:
- Significant horizontal skin redundancy
- Loose skin in the upper abdomen or beneath the rib cage
As a result, some post-weight-loss patients are left with residual skin excess above the level of the incision, even after well-performed surgery.
The Fleur-de-Lis Abdominoplasty and Its Limitations
The Fleur-de-Lis abdominoplasty was developed to treat more complex patterns of skin excess. In addition to the lower horizontal incision, it incorporates a vertical midline incision. This allows removal of excess skin in both vertical and horizontal directions across the anterior abdomen.
For many post-weight-loss patients, the Fleur-de-Lis approach provides correction of central abdominal laxity compared with a traditional abdominoplasty alone. It is particularly useful when there is significant vertical skin redundancy that cannot be corrected with a horizontal incision.
Despite its advantages, the Fleur-de-Lis abdominoplasty also has limitations. While it treats contour of the central abdomen, it does not directly target excess skin in the upper abdomen or lower chest area. In patients with significant upper abdominal skin laxity, this region may be left untreated, resulting in persistent laxity above the vertical incision.
This limitation is a key consideration when planning surgery for patients with complex, multidirectional skin excess.
The Upper Abdomen and Lower Chest: An Often Overlooked Area
In post-weight-loss patients, excess skin frequently extends beyond the traditional boundaries of abdominoplasty surgery. The upper abdomen and lower chest region can accumulate loose skin that descends toward the abdomen after weight loss.
This area is not effectively treated by traditional or Fleur-de-Lis abdominoplasty techniques, as both rely primarily on downward or central tension vectors. Without a direct excision in the upper abdomen, skin in this region may persist.
Recognising and treating this pattern of skin excess is central to the rationale behind Dual Vector Abdominoplasty.
Upper Abdominal Lipectomy: Addressing the Upper Vector
An upper abdominal lipectomy involves the removal of excess skin from the upper abdomen through a transverse incision placed beneath the breast or chest crease. This technique directly targets loose skin in the upper abdomen by excising it, rather than attempting to redistribute it.
When performed in isolation, upper abdominal lipectomy is rarely appropriate. However, when combined with a Fleur-de-Lis abdominoplasty, it allows comprehensive treatment of excess skin across the entire anterior abdomen.
The Dual Vector Abdominoplasty Concept
Dual Vector Abdominoplasty combines a Fleur-de-Lis abdominoplasty with an upper abdominal lipectomy in a single operation. This approach allows skin excision along two distinct vectors:
- A lower and central vector via the Fleur-de-Lis component
- An upper vector via the upper abdominal lipectomy
The resulting incision pattern resembles a sideways “H”, consisting of a lower abdominal horizontal incision, a vertical midline incision, and an upper abdominal horizontal incision. This configuration allows targeted removal of excess skin that would otherwise remain untreated.

Abdominal Muscle Considerations
During abdominoplasty surgery, the abdominal muscles are assessed. If muscle separation is present, repair may be performed to treat the abdominal wall support. Not all patients require muscle repair, and this decision is made on an individual basis.
It is important to note that muscle repair does not replace weight loss or exercise. The primary goal of Dual Vector Abdominoplasty remains the removal of excess skin and the improvement of abdominal contours.

Belly Button Management
The belly button is usually preserved during abdominoplasty procedures. Its position may change as excess skin is removed and contours are adjusted. Care is taken to maintain appropriate placement relative to surrounding anatomy; however, outcomes vary among individuals.
Combining Dual Vector Abdominoplasty With Other Procedures
In selected patients, Dual Vector Abdominoplasty may be performed alongside other body contouring procedures, including:
- Breast lift (mastopexy)
- Breast augmentation (Augmentation mammoplasty)
- Body lift (belt lipectomy) or lower body contouring
- Limited fat removal or combining liposuction
Combining procedures can allow multiple areas to be treated during a single recovery period. However, patients’ overall surgical risk is carefully considered, and not all patients are suitable for multiple procedures.
Recovery Period and Healing Process
Recovery following Dual Vector Abdominoplasty is generally longer than after a standard abdominoplasty due to the extent of surgery involved. The healing process occurs in stages and varies between individuals.
Early recovery typically involves:
- Reduced physical activity
- Wearing a compression garment
- Regular follow-up appointments
As healing progresses, patients gradually return to normal activities. Adherence to postoperative instructions is essential to support wound healing and minimise complications.
Scarring and Scar Management
Due to the incision pattern required, visible scars are an expected part of Dual Vector Abdominoplasty. These include:
- A lower abdominal scar near the bikini line
- A vertical midline abdominal scar
- An upper abdominal horizontal scar
Scar management strategies are discussed as part of postoperative care. Scars are permanent but typically change in appearance over time.
Risks and Complications
As with all cosmetic surgery, Dual Vector Abdominoplasty carries risks. These may include:
- Poor wound healing
- Seroma formation
- Infection or bleeding
- Deep vein thrombosis
- Pulmonary embolism
- Need for revision surgery
All patients must understand that outcomes cannot be guaranteed and that individual healing varies.
Final Thoughts
Dual Vector Abdominoplasty is a complex surgical approach designed for a specific group of post-weight-loss patients with challenging patterns of abdominal skin excess. It is not a substitute for weight loss and is not appropriate for everyone.
A thorough consultation is essential to determine suitability, discuss risks, and establish realistic expectations
