BUTTOCK AUGMENTATION

Dr Chia Hui Ling

Buttock augmentation increases the size and improves the shape of the buttocks, usually using either implants or a patient's own fat (fat grafting, sometimes called a Brazilian Butt Lift). The two approaches differ enough in technique, recovery, and risk that the choice between them deserves careful discussion before deciding.


•      Adds volume and projection to a flatter or asymmetric buttock area

•      Can improve overall body proportion, particularly the waist-to-hip silhouette

•      Fat grafting has the added benefit of contouring the donor liposuction sites at the same time

•      Implants provide a more predictable, non-absorbable volume increase

•      Can correct asymmetry between the two sides

•      For fat transfer: sufficient donor fat elsewhere on the body to harvest safely

•      For implants: adequate soft tissue and muscle coverage to support an implant

•      Good general health with no uncontrolled medical conditions

•      Realistic expectations about how much volume is achievable and how much fat may be reabsorbed

•      Willingness to avoid direct sitting pressure on the buttocks for several weeks afterward



Whichever technique is chosen, this is a procedure where discussing the specific risks with your surgeon matters more than usual, since some of the rare complications associated with fat grafting to this area are serious.


TREATMENT

Buttock augmentation is performed under general anaesthesia and the technique depends on which approach is chosen.



  • Fat grafting: at is harvested by liposuction from areas such as the abdomen, flanks, or thighs, processed, and then carefully injected into the buttocks in layers, staying above the muscle
  • Implants: silicone implants are placed either within or beneath the gluteal muscle through a small incision, usually in the crease between the buttocks
  • Surgery typically takes two to four hours depending on the technique and extent of contouring
  • A compression garment is worn afterward to support healing and reduce swelling at donor sites
  • First 2-3 weeks: avoid sitting or lying directly on the buttocks; special cushions or lying face-down are used instead
  • 3-6 weeks: gradual, cautious return to sitting for longer periods and light activity
  • 6-8 weeks: gradual return to exercise, guided by your surgeon
  • With fat grafting, a portion of the transferred fat is reabsorbed by the body over the first few months, which your surgeon accounts for when planning volume


  • Preparing for Surgery

    Do inform your plastic surgeon of previous surgeries, any medical conditions and medications. Avoid blood-thinning medications, anti-inflammatory drugs or herbal supplementations as they can increase the risk fo excessive bleeding during surgery, unless indicated by your doctor.

  • Surgery

    1. Buttock implant 


    This procedure can be done under sedation or general anesthesia. An incision can be placed at your lower buttock crease, hidden between your buttock cheeks etc. A silicone implant specially made for the buttocks is inserted in the muscle or on top on the muscle. Results can be seen immediately and are permanent. 


    2. Fat grafting/Brazilian butt lift


    This procedure can be done under sedation or general anesthesia. Liposuction is perfomed to harvest the fat graft which are subsequently injected into your buttocks with small injections. Results are immediately visible however final results may only be seen after a year of the surgery. This procedure offers results that look and feel natural but the buttock projection may decrease overtime as some of the orginal volume of fat is absorbed by the body (60-80% of transferred fat is retained in most individuals). Transferred fat retains the nature of  other fat in the body and can grow or shrink in weight gain/loss.


    3. Buttock lift


    This procedure can be done under sedation or general anesthesia. A common technique uses an incision placed just below the waist line and is commonly combined with an abdominoplasty incision in a body contouring procedure. Liposuction may be used for contouring as well. Incisions may also be placed below the buttocks and in the buttock and upper thigh crease. Excess skin and tissues are removed to provide a more defined crease and smoothens the skin of the back of the upper leg. Reults are visible almost immediately however time is required for swelling and normal post-operative inflammation to resolve.

  • Post-Surgery Care

    In the immediate post-operative period, patients may experience some bruising and mild pain, which are expected and can be managed very well with medication. Small thin tubings may be placed uner the skin to drain excess blood or fluid. You may go home after a few hours post surgery. You will be instructed to wear a support garment at all times after surgery. If you underwent fat grafting you may be asked to avoid prolonged sitting for about 2 weeks as sitting may damage the fat from fat grafting. 


    Further down the road, patients are followed up for healing and scar management. 

COMPLICATIONS AND MANAGEMENT

Both techniques carry general surgical risks, but each also has specific concerns worth understanding.


•      Fat embolism: a rare complication where fat enters the bloodstream, which is why staying above the muscle during injection is important

•      Unpredictable fat resorption, meaning final volume can be somewhat less than immediately after surgery

•      Contour irregularities at either the injection site or the liposuction donor areas

•      Infection, which can be more difficult to manage if an implant is present

•      Implant-specific risks: malposition, rotation, capsular contracture (firm scar tissue around the implant), and implant palpability or visibility

•      Fluid collection (seroma) at donor or recipient sites

•      Wound healing problems, particularly along the buttock crease incision for implants

•      Asymmetry between the two sides


FAQs

Which is better: implants or fat transfer?

Neither is universally better; the right choice depends on your body type, how much donor fat you have, and how you weigh the risks of each. Implants give more predictable, permanent volume, while fat transfer gives a more natural feel but with some volume loss over time.

How long do results last?

Implants are generally permanent, though they may eventually need revision surgery. Fat that survives the initial resorption period tends to behave like normal fat, so results are reasonably stable but can change with significant weight fluctuation.

When can I sit normally again?

Most surgeons advise avoiding direct pressure on the buttocks for two to three weeks, with a gradual return to normal sitting over the following weeks using cushioning support.

Is fat transfer to the buttocks safe?

When performed with fat kept above the muscle layer, the serious risks associated with this procedure are substantially reduced, though they are not eliminated. This is an important safety conversation to have directly with your surgeon.

Will the transferred fat just disappear?

A proportion of transferred fat is reabsorbed in the first few months, which is normal and expected. What remains after that period tends to be stable, though your surgeon will plan the initial volume with this loss in mind.

Can implants and fat transfer be combined?

In some cases yes, though this adds complexity and recovery time. Whether it is appropriate depends on your anatomy and goals, and is best discussed individually.
