Introduction to breast reconstruction using autologous fat transfer (AFT) 

David Crabb is leading the way with a scientifically-proven and more natural alternative to breast reconstruction for women following breast cancer surgery. The same no knife procedure can be used for breast augmentation, defect corrections and congenital asymmetries.
The technique has been developed by the highly respected and much published Dr. Roger Khouri, plastic surgeon at the Miami Breast Centre.
David Crabb (plastic surgeon), who has trained with Dr Khouri, is the leading New Zealand surgeon trained in this procedure.

The procedure

The procedure is less invasive and less stressful on your body than previous methods, and recovery time is quick. Patients go home on the day of surgery.

If there is sufficient skin following a mastectomy, the reconstruction can generally be achieved.

In cases of total mastectomy with severe skin shortage, the fast track is to do a first round of fat grafting to correct any concavity, reverse radiotherapy changes and free tethered scars.

This then provides the platform for stage two, which is a latissimous dorsi flap with further fat grafting, giving a quick, natural looking reconstruction with no prosthesis.

For many patients, this technique is a huge leap forward from reconstruction procedures of the past, which require major surgery and come with the disadvantages of implants in many cases.

David Crabb can rebuild your breast from your own fat. It will feel normal and real.
The technique is minimally invasive and has the side benefit of utilising liposuction to harvest the fat from areas of your body with unwanted fat, e.g. thighs, hips, medial knees and stomach.
Final breast size will be discussed between you and David Crabb, and factors such as your body shape, available fat and the condition of your skin will be considered.

The procedure is suitable for breast reconstruction salvage from previous operations that have not gone well or implants that have become infected or displaced.

Removal of implants and replacement with fat grafts will result in a more natural appearance.


Fat transfer process

David Crabb removes fat from one area of your body and meticulously injects it back into the prepared area as hundreds of tiny individual droplets in the breast site. These micro-fat transfers are harvested by
gentle liposuction from the thighs, buttocks and stomach – wherever there is fat to spare. Even slender patients do well with this procedure as we usually find enough fat cells. The fat then “takes” like a graft
with gradual replacement by cells that grow in.
Fat cell survival is between 50% and 95% with an average of two thirds and up to 80 percent. 

Suitable indications for AFT reconstruction

1. Following breast cancer surgery: Most patients who have had a mastectomy will do well with this procedure.
Loose abdominal tissue can be recruited and slid upwards to assist in your breast creation.
Collapsed skin with tethered scars may need some preliminary work. Tethered scars can also be released during the fat grafting procedure.
Radiotherapy damaged skin does very well with fat grafting and the technique is now in use in the UK and the USA to treat radiation burns.
It works by allowing the damaged blood supply to recover.
In severe cases of scarring and tethering, scar revisions may be needed as a preliminary step.

2. Salvage cases: Implant failure or flap failure can be a good indication for AFT.
Implants are removed and fat grafting can then be done into the skin flaps and underlying muscle to complete the first stage in preparation for the BRAVA use.

3. Implant Removal: There is a fraught and complicated history regarding implants. I have never liked them as they carry a high failure rate and it commits the patient to further surgeries.
​Removal of unsatisfactory implants is performed using a lateral approach. This allows the surgeon access to place micro fat grafts into the tissues anterior to the cavity. It is not possible to place fat directly into the cavity because there is no blood supply to sustain it.

For most cases, there is sufficient lax tissue to complete a reconstruction in one round. For breast reconstruction after cancer, where there is more scarring, additional rounds may be required.



The procedure is done as an outpatient (no overnight stay required), under general anaesthesia and sedation.


Average recovery time is 2-4 days, a lot quicker than all other forms of breast reconstruction.
The benefits of our procedure include:


  1. No foreign object in body
  2. Quick recovery
  3. No cuts, no incisions
  4. Liposuction
  5. No implant problems
  6. Minimally invasive

Am I a candidate?

Most women are candidates for our Brava and AFT breast regeneration procedure. There are only four disqualifiers:
1. Smoking: Smokers have a poor capacity to regenerate tissue. We recommend that a patient stops smoking at least two months before the procedure and abstain completely throughout the process, and for three months after. If she cannot comply, we cannot help her.
2. Herceptin® chemotherapy and other angiogenesis inhibitors: These prevent the revascularization of the fat graft and lead to a poor outcome. We recommend the process be started about one month after a patient completes her course of Herceptin treatment.
3. Aspirin, over-the-counter food supplements and vitamins that may impair blood clotting: It is imperative that the patient stops aspirin, all vitamins, and all herbal supplements at least two weeks before the procedure.
4. Poor understanding of the procedure: A GP referral letter with your history would be the preferred first contact prior to consultation.
Alternatively, David Crabb is happy to liaise with the oncology team or the oncological surgeon to ensure timing for the procedure is optimum.
Your first contact with David Crabb may be by e-mail. He may request photos and medical details of your treatment to date. These e-mails are treated as confidential medical records.
Additional planning may be required and approval will be sought from your insurance company.
At your appointment, your history and medications will be reviewed and your smoking status taken. Your breast or mastectomy site will be examined and photographed. The distribution of fat is examined and
unwanted areas of fat are identified.
A general discussion will ensue. An estimate of the costs will be provided at this time and, if you are insured, approval is then sought from your insurance provider.
A nurse contact number will be provided for ongoing support.
