In short. When the two are done together, what changes in recovery, garment time and risk, and when staging them as separate operations is the better plan.
Key points
- The result of a combined operation is usually better than either alone.
- The question worth asking is what the combination adds in anaesthetic time, hospital stay, garment weeks and risk over doing one of them.
- A surgeon who can set those out numerically in days is describing a plan.
These two operations address different tissues in the same region, which is why they are frequently discussed together and sometimes done at once. Fat removal changes the outline at the flanks and the waist. An abdominoplasty removes skin and repairs separated abdominal muscle. Where a patient has both a waist that holds fat and an abdomen that has skin to remove, the combination can produce a result neither achieves alone. It is also a substantially larger operation.
Why they are often considered together
Geography, mostly. The abdominoplasty incision and the areas treated by fat removal meet, and doing them in one operation avoids leaving a boundary between the treated and untreated territory that would otherwise have to be managed in two stages. There is also one anaesthetic and one recovery period rather than two, which patients reasonably value.
What changes when they are combined
The operation is longer, sometimes by several hours. The hospital stay is more likely to include a night or two. Drains are more likely to be used, and the garment is worn for longer. The first fortnight is harder than for either operation alone. And the rate of fluid collecting under the skin — the complication an abdominoplasty is best known for — is higher than for a contouring operation on its own, and it may need draining more than once.
Ask how the plan changes the recovery, not just the result
The result of a combined operation is usually better than either alone. The question worth asking is what the combination adds in anaesthetic time, hospital stay, garment weeks and risk over doing one of them. A surgeon who can set those out numerically in days is describing a plan. One who describes the combination only in terms of the result is describing the destination rather than the journey.
When staging is the better plan
When the combined operation would be too long or too much for the patient's general health. When a patient wants to judge the first result before committing to the second. And when the plan is large enough that doing it all at once would push the volume beyond what is safe in a single session. Staging costs a second anaesthetic and a second recovery, and it lowers the risk each operation carries.
Questions that should be answered before consent
- How much longer is the operation when the two are combined, and how many nights in hospital?
- How much longer is the garment worn, and what does the drain plan look like?
- What is the plan if fluid collects under the skin, and who manages it in the weeks afterwards?
Neither route is a compromise. A combined operation is the right answer for some patients and a staged plan is the right answer for others, and the deciding factors are general health, the size of the total plan and how much recovery can be accommodated at once. What is not acceptable is a combination presented as a fuller version of one operation, because it is a different operation with its own risks.
Frequently asked questions
Why would the two be combined rather than done separately?
Because they address different tissues in overlapping territory. The abdominoplasty removes skin and repairs separated muscle in the middle, and contouring the waist removes fat at the flank. Doing them together avoids a boundary between the two areas and avoids a second anaesthetic and a second recovery. It also makes for a considerably bigger single operation.
What changes in recovery when they are combined?
Everything is longer and heavier. The operation takes more hours, the hospital stay is more likely to include a night or two, drains are more likely, the garment is worn for longer and the first fortnight is harder. The rate of fluid collecting under the skin is higher than for either operation alone, and it may need draining.
When is staging the better plan?
When the combined operation would be too long or too much for the patient's health, when the two problems can be addressed in either order without compromising the other, or when the patient wants to judge one result before deciding on the second. Staging costs a second anaesthetic and a second recovery, and it lowers the risk carried by each operation.
Risks & Limitations
- A step-off — a visible ledge where treatment stops at the rib cage or the hip — is the risk specific to contouring, and it is not always fully correctable.
- Contour irregularity and asymmetry are the commonest lasting complaints, and are more likely after a large volume or a treatment concentrated in the centre of the waist.
- Fat removal is contouring, not weight loss. The scale often barely moves, the fat that remains responds to weight change, and fat inside the abdomen is not reached at all.
- A clot in the deep veins of the leg is uncommon and serious, and is why clot prevention is planned before the operation rather than decided after it.
When to Seek Care
- Pain, swelling, warmth or redness in one calf, or sudden breathlessness or chest pain — possible clot; seek emergency care immediately.
- Fever, spreading redness, warmth or discharge from an access point or wound.
- A swelling under the skin that is new or increasing, or fluid leaking from an access point.
- A hard, defined ledge or a bulge that is increasing rather than settling, or an area that becomes tender and warm.
