A torsoplasty is a plastic surgery procedure that removes excess skin and fat from the torso, most commonly the back. It’s sometimes called a back lift, back reduction, or upper body lift, and it’s one of the most common body contouring surgeries for people who have loose, hanging skin after major weight loss. The procedure can target everything from isolated back rolls to widespread excess tissue across the entire upper and lower torso, including the flanks and buttocks.
What a Torsoplasty Addresses
After rapid, significant weight loss (whether from bariatric surgery or other means), the skin often can’t shrink back to match a smaller body. In the upper torso, this shows up as mid-back and upper-back rolls, sagging breasts, and hanging arm skin. In the lower torso, it can create an abdominal “apron” (called a pannus), excess tissue in the flanks, and drooping buttocks. A torsoplasty is designed to surgically remove this redundant tissue when no amount of exercise or time will tighten it on its own.
The specific version of the procedure depends on where and how much excess skin you have. A circumferential torsoplasty addresses the lateral flank rolls, abdominal excess, and buttock sagging all at once by making incisions that wrap around the body. Smaller procedures target just the back.
Types of Torsoplasty
Not everyone needs the same operation. Surgeons choose from several approaches based on the severity of skin laxity:
- Back liposuction alone: suitable if you have minimal loose skin and your skin still contracts well on its own.
- Partial vertical torsoplasty: for more extensive back skin excess, using a vertical incision pattern.
- Extended partial vertical torsoplasty: when excess skin and fat are significant enough that the incision needs to extend down to the hip bone (the top of the iliac crest).
- Horizontal torsoplasty: for excess skin spanning the entire upper back, with an incision running horizontally across the back. This is sometimes called a bra-line lift or bra-straplasty because the scar sits roughly where a bra strap would fall.
- Circumferential torsoplasty: the most extensive version, wrapping incisions around the full torso to address the back, flanks, abdomen, and buttocks simultaneously.
How It Differs From a Lower Body Lift
The terms can get confusing because they overlap. A torsoplasty is generally considered an upper body lift, focusing on back rolls and the upper torso. A lower body lift targets the abdomen, hips, thighs, and buttocks, with scars positioned low enough to hide under underwear. A circumferential torsoplasty blurs this line because it addresses both upper and lower areas. In practice, your surgeon will recommend one or a combination based on exactly where your excess tissue sits. Some people need both procedures, staged months apart.
Who Is a Good Candidate
The best candidates have reached a stable weight and maintained it for at least three to six months. Most surgeons want you to be at least one year out from bariatric surgery before operating. The typical BMI at the time of a body contouring consultation ranges from about 25 to 35, but outcomes are best for patients with a BMI under 30, few medical conditions, and no active smoking habit.
Smoking is a serious concern because it impairs blood flow to the skin flaps, dramatically increasing the risk of wound healing problems. Most surgeons require you to quit well before surgery and stay off cigarettes throughout recovery. People on blood-thinning medications or with a BMI of 35 or higher are generally considered poor candidates due to elevated complication risk.
What Happens During Surgery
A torsoplasty is performed under general anesthesia. For procedures that involve the back, you start face-down on the operating table, often with your feet elevated slightly (a position called Trendelenburg) to improve access. The surgeon marks the borders of the tissue to be removed, makes incisions along those borders, and excises the excess skin and fat. In some techniques, tissue flaps are tucked into pockets and anchored with internal stitches to create volume and shape, particularly in the buttock area.
For a circumferential procedure, the surgical team repositions you during the operation to access the front of the torso as well. The abdominal portion may use both vertical and horizontal incisions (a pattern called fleur-de-lis) to remove tissue in two directions. The entire operation can take several hours depending on how many areas are treated.
Where the Scars End Up
Scar placement is a key part of surgical planning. For a horizontal torsoplasty, the scar runs across the back and is designed to sit along the bra line so clothing conceals it. Some techniques position scars along the front of the armpit fold (the anterior axillary pillar) and around the breast, where they’re naturally hidden by the body’s contours. For a lower body lift component, the posterior scar is placed low enough to sit beneath underwear or a swimsuit bottom.
Scars from a torsoplasty are long, and they’re permanent, though they typically fade and flatten over the first one to two years. Silicone scar sheets, sun protection, and gentle massage once wounds are fully closed are common strategies for minimizing their appearance.
Recovery Timeline
Recovery from a torsoplasty is significant. This is major surgery involving large incisions, and your body needs time to heal.
Surgical drains are placed during the procedure to prevent fluid from collecting under the skin. These are typically removed around 12 to 13 days after surgery in uncomplicated cases, though patients who develop complications may keep drains closer to 16 days. Some surgeons now practice earlier removal (as soon as day 7) when drainage volumes are low, which can shorten your hospital stay.
You’ll wear a compression garment around the clock for the first two to six weeks. These garments reduce swelling, support the healing tissues, and help your new contours take shape. After the initial full-time period, most people taper to wearing the garment 12 to 18 hours a day, then transition to lighter compression. By 8 to 12 weeks, most patients stop wearing compression full-time, though some continue with lighter shapewear for comfort.
Most people can return to desk work within two to four weeks, depending on the extent of the procedure. Heavy lifting and vigorous exercise are typically off-limits for six to eight weeks. Swelling continues to resolve gradually over several months, so your final results won’t be visible right away.
Potential Complications
Body contouring surgery after massive weight loss carries a meaningful complication rate. In one clinical study of post-bariatric patients, the most common complications were seroma (fluid collection under the skin) at 36%, wound separation with delayed healing at 16%, hematoma (blood collection) at 12%, and wound infection at 8%. Deep vein thrombosis occurred in 4% of patients.
These numbers are higher than many elective cosmetic procedures, which reflects the reality that post-weight-loss patients are working with skin that has reduced elasticity and blood supply. Careful surgeon selection, maintaining a stable weight before surgery, not smoking, and following post-operative instructions closely all help reduce these risks.
Cost
The average surgeon’s fee for a body lift is $11,397, according to the American Society of Plastic Surgeons. That figure covers only the surgeon’s time. It does not include anesthesia, the surgical facility, medical tests, compression garments, or prescriptions. The total out-of-pocket cost is typically several thousand dollars higher. Insurance coverage varies: some plans cover body contouring after massive weight loss when there’s a documented medical need (such as chronic skin infections or rashes under skin folds), but many classify it as cosmetic.
