Lipoplasty is the medical term for liposuction, the surgical removal of excess fat from specific areas of the body. The two words describe the same procedure. In 2024, it was the most popular cosmetic surgery in the United States, with nearly 350,000 procedures performed.
How the Procedure Works
The basic concept is straightforward: a surgeon makes small incisions, inserts a thin hollow tube called a cannula, and uses it to loosen and suction out fat. Before extraction begins, a diluted anesthetic solution is infused into the treatment area to reduce bleeding and trauma. The cannula moves back and forth in a controlled motion to break up fat deposits, which are then pulled out with a surgical vacuum or syringe.
You’ll receive either intravenous sedation or general anesthesia depending on how much fat is being removed and how many areas are being treated. Many people have multiple zones addressed in one session, such as the abdomen and flanks together, or both inner and outer thighs.
Types of Lipoplasty
Several variations exist, each using a different method to break up fat before suctioning it out.
- Tumescent lipoplasty is the most common approach. A large volume of fluid containing local anesthetic is infused until the treatment area becomes firm and swollen. After about 8 to 10 minutes, the skin blanches from reduced blood flow, which minimizes bleeding during fat removal.
- Ultrasound-assisted lipoplasty uses ultrasonic energy to create tiny bubbles within fat tissue. These bubbles burst and break apart fat cell membranes, making the fat easier to suction out. This technique is often used in denser, more fibrous areas.
- Power-assisted lipoplasty uses a cannula with a mechanically rotating tip. The vibration does more of the physical work of loosening fat, which reduces strain on the surgeon and can shorten procedure time.
- Laser-assisted lipoplasty delivers laser energy through a thin fiber to liquefy fat before removal. It also heats the surrounding tissue, which may promote some skin tightening.
Common Treatment Areas
The abdomen is the single most popular target for both men and women, particularly for lower belly fullness that persists after weight changes, pregnancy, or age-related metabolic slowdown. The flanks (often called love handles) are frequently treated alongside the abdomen to create a more defined waistline.
Thigh lipoplasty is especially common among women. Outer thigh fat can make the lower body appear wider, while inner thigh fat often causes friction and discomfort. Upper arms are another frequent request, targeting fullness that typically doesn’t respond well to exercise alone. Even a small pocket of fat under the chin can noticeably change your facial profile, and submental lipoplasty (about 24,000 procedures in 2024) addresses that area specifically.
Who Is a Good Candidate
Lipoplasty works best for people who are close to their goal weight but have localized fat deposits that won’t budge with diet and exercise. Most surgeons prefer candidates with a BMI under 30 who are within about 30 pounds of their ideal weight and have maintained that weight for at least six months.
Skin elasticity is a factor that often gets overlooked. When fat is removed, the overlying skin needs to shrink and conform to the new contour. You can get a rough sense of your skin quality with a simple pinch test: grab the skin on your abdomen, release it, and see how quickly it snaps back. If it returns slowly or wrinkles, your elasticity may be reduced, and a surgeon might recommend combining lipoplasty with a skin-tightening procedure like a tummy tuck. Younger patients in their 20s and 30s generally have the best elasticity and often achieve smooth results with lipoplasty alone.
Nonsmoking status matters significantly. Smoking impairs healing and is directly linked to higher rates of skin complications after surgery. Most surgeons require you to quit several weeks before and after the procedure.
Recovery Timeline
Swelling appears within 24 to 48 hours and continues to increase mildly over the first 10 to 14 days. Bruising peaks around 7 to 10 days and generally fades within 2 to 4 weeks. Neither is a complication. Both are normal tissue responses to the physical disruption of the cannula.
Compression garments are central to recovery. During the first week, you’ll wear one nearly around the clock, removing it only to shower. After that first week, most people transition to wearing it about 12 hours a day during waking hours. By weeks 5 and 6, you typically only need it during physical activity. Some surgeons recommend occasional use for up to 3 to 6 months, especially for larger treatment areas. These garments reduce swelling, support the tissue as it heals, and help skin conform to its new shape.
Most people return to desk work within a few days to a week, though physical labor and exercise take longer. Final results aren’t visible immediately because of swelling. It can take several months for the treated area to settle into its new contour.
Risks and Complications
Fluid collection (seroma) occurs in roughly 3.5% of cases, most commonly in the outer thighs, posterior thighs, and lower abdomen. These pockets of fluid typically show up around the 5th to 7th day after surgery. Poorly fitting compression garments or repeatedly removing and replacing them increases the risk.
Skin necrosis, where a patch of skin dies due to damaged blood supply, occurs in about 1% of cases. The risk rises with smoking, use of sharp cannulas, overly aggressive suctioning close to the skin surface, and combining lipoplasty with other procedures like a full tummy tuck.
The most serious potential complication is fat embolism syndrome, where fat droplets enter the bloodstream and travel to the lungs. This is rare but carries a mortality rate of 10 to 15% when it does occur. Symptoms typically appear within 12 to 24 hours. The risk increases with very large-volume fat removal, sometimes called mega-liposuction. Contour irregularities (lumps, dents, or asymmetry) are also possible, particularly if too much or too little fat is removed from a given area.
How Long Results Last
Fat cells that are removed during lipoplasty do not grow back. In that sense, the results are permanent. However, the remaining fat cells in the treated area can still expand if you gain weight, and fat may deposit disproportionately in untreated areas. Someone who gains a significant amount of weight after lipoplasty often finds their body stores fat differently than it did before, which can look uneven.
Maintaining a stable weight through consistent eating and exercise habits is the most important factor in preserving your results long term. Weight fluctuations also affect skin and muscle tone, which can diminish the contouring effect over time.
Cost and Demographics
The average surgeon’s fee for lipoplasty is $4,711, but that number covers only the surgeon. Anesthesia, the operating facility, compression garments, medical tests, and prescriptions are all additional. Total cost varies widely depending on the number of areas treated, the technique used, and geographic location.
Women account for 94% of cosmetic lipoplasty procedures. The largest age group is 40 to 54, making up 45% of all procedures, followed by 30 to 39 year olds at 26%. About 18% of patients are between 55 and 69, and a small but notable 2% are 70 or older. Lipoplasty is also performed as a reconstructive procedure for lipedema, a chronic condition involving abnormal fat accumulation, with nearly 30,000 such procedures recorded in 2024.
