FAT TRANSFER BREAST AUGMENTATION

Dr Chia Hui Ling

Fat transfer breast augmentation uses your own fat, harvested by liposuction from areas such as the abdomen, flanks, or thighs, and reinjected into the breasts. It suits people who want a modest, natural increase in size without an implant, and it comes with the side benefit of some contouring at the donor site.


•      Adds volume using your own tissue, so the breast tends to look and feel natural

•      Avoids implant-related risks such as capsular contracture or rupture

•      Contours the donor area at the same time, such as the abdomen or thighs

•      Leaves only small liposuction and injection scars rather than a larger incision

•      You have adequate donor fat available for harvesting

•      You are seeking a subtle to moderate increase, typically around half to one cup size per session

•      You are not seeking the dramatic size change that only an implant can achieve

•      You are in good general health and a stable, non-smoking weight

Because a proportion of the transferred fat does not survive, results are more modest than implants, and some people choose to repeat the procedure after the first has settled to build further volume.


TREATMENT

Have a thorough discussion with your plastic surgeon, including your surgical goals, medical conditions, drug allergies, medications and previous surgeries. If you are seeking a size increase beyond a cup size or have little body fat reserves, an implant breast augmentation  or hybrid breast augmentation may be a better choice. Women with significant breast ptosis, or sagging breasts, a breast lift or mastopexy may be indicated for a more aesthetic result. Expected outcomes, risks and other treatment options should be explained to you.


The procedure is performed under sedation or general anaesthesia as day surgery, combining liposuction with fat grafting in the same session.



•      Fat is harvested gently by liposuction from a donor area with adequate reserves

•      The fat is processed to separate viable fat cells from fluid and damaged cells

•      Purified fat is injected into the breast in small amounts, in multiple layers and directions, to maximise survival and even distribution

•      The whole procedure usually takes two to three hours depending on the volume needed

•      Both the donor site and the breasts are tender and bruised for one to two weeks

•      A compression garment is worn over the donor area for several weeks

•      Most people return to desk work within a week, and to exercise within four to six weeks

•      Final breast volume is only apparent after three to four months, once resorption has stabilised




  • Preparing for Surgery

    Do inform your plastic surgeon of previous breast conditions and surgeries, any medical conditions and medications. Your surgeon may send you for breast screening if you are approaching or more than 40 years old. Avoid blood-thinning medications, anti-inflammatory drugs or herbal supplementations as they can increase the risk of excessive bleeding during surgery, unless indicated by your doctor.

  • Surgery

    Using liposuction, fat is aspirated from other parts of the body, commonly the tummy or thighs.  The fat harvest is processed using the surgeon’s method of preference, such as the Coleman’s technique, Lipokit or Puregraft. The prepared fat is injected into the breasts via small puncture wounds.

  • Post-Surgery Care

    There will be swelling and bruising after injection and most of this will resolve at the end of a week. Your surgeon may advise against upper body exercises for a few weeks. With the resorption of fat over time, the size of the breasts after fat transfer will stabilise around 3 months.

COMPLICATIONS AND MANAGEMENT

How much bigger will my breasts get?

Most people see an increase of around half to one cup size per session, since only a portion of the transferred fat survives long-term. Larger increases usually require more than one session.

Is the fat transfer permanent?

Fat that survives the first three to four months tends to remain, behaving like the rest of your body fat, so it can fluctuate slightly with your weight.

Does this affect future mammograms?

It can introduce benign calcifications or fat necrosis that show up on imaging, but radiologists experienced in post-surgical breasts are usually able to tell these apart from concerning findings. It is worth mentioning your history at every screening.

Can I combine this with a breast lift?

Yes, fat transfer is sometimes combined with a lift if there is sagging alongside volume loss, though this adds to recovery time and surgical planning.

Do I need enough fat elsewhere on my body?

Yes, you need a reasonable donor supply, so this option suits people with some fat to spare rather than those who are very lean.

How long is recovery for the donor area?

Bruising and soreness at the liposuction site usually settle within two to three weeks, though final contouring is seen closer to three months.


COMPLICATIONS AND MANAGEMENT

Fat grafting is generally gentler than implant surgery, but it carries its own specific risks that are worth understanding.


•      Not all transferred fat survives; a variable proportion is reabsorbed by the body over the following months

•      Fat necrosis or oil cysts can form where fat does not survive, sometimes felt as small firm lumps

•      Calcifications can develop at these sites and may appear on future mammograms, though radiologists are generally able to distinguish these from cancer-related changes

•      Asymmetry or unevenness if fat survival differs between breasts

•      Contour irregularities at the donor liposuction site

•      Infection or bleeding, though these are uncommon
