Autologous Fat Transfer

Brustvergroesserung FrauAutologous fat transfer (transplantation) has been considered one of the main applications used in plastic surgery since 2001. It is used among others for rejuvenation / beautification of the face, for the correction of scar tissue, to improve the skin and for breast augmentation.

Besides the use in cosmetic medicine, fat grafting is also used in reconstructive surgery. It is ideal for the correction of tissue defects, asymmetries, level formations or dents subsequent to reconstructive interventions.

With the discovery of stem cells in adipose tissue (2001), previously unimagined possibilities opened up for fat grafting using the stem cells of the fatty tissue called ADSC (adipose-derived stem cells). ADSC differ from the fat cells mainly through the valuable property of being able to evolve as a function of their environment in different cell types (niche theory). These include inter alia skin tissue, connective tissue, blood cells, blood vessels and fat cells. ADSC quickly established itself worldwide with high-paying university research groups, pursuing and investigating all possibilities of ADSC to improve surgical results.

Where can an autologous fat transfer be applied?

Below are some examples in which autologous fat transfer can be used:

  • Improvement of skin quality in general
  • Improving the appearance of scars
  • Improving the skin after irradiation
  • Improving the skin after burns
  • Correction of tissue defects
  • Form of improvement in reconstructive breast correction
  • Aesthetic correction of the face (dark circles, nasolabial folds, lips, sunken eyes, malar region, frown lines, nose, chin, etc.)
  • Cosmetic Breast Augmentation
  • Cosmetic correction of other body areas (hands, buttocks, labia, penis, etc.)

The healing rate of transplanted fat varies between 30-80%, therefore several sessions may be needed to achieve the desired effect. The operating effort of fat transplantation and the associated costs appeared to be higher than injecting artificial fillers (hyaluronic acid, etc.). In the long term, however, fat transplantation is cheaper and less time-consuming. Artificial fillers are known to be degraded after 6 months from the body and must therefore be repeated at regular intervals.

What are the advantages of autologous fat transfer?

  • Autologous fat is free and almost always available in sufficient quantities.
  • Allergic reactions and/or intolerances are excluded.
  • Healed fat is not reduced and the result obtained is thus permanent.

Fat transplantation has become an integral part of modern cosmetic surgery. In experienced hands, the results are excellent and patient satisfaction is especially high.

Before & After Photos Autologous Fat Transfer

Here you can see some examples of autologous fat transplantation. Autologous fat is the most natural and best filler, there is no incompatibility. Autologous fat is free, and the result is, in contrast to artificial filler substances ( hyaluronic acid, etc.), which degrade within 4-6 months, permanent. Autologous fat is used primarily for facial rejuvenation ( dark circles, nasolabial folds, lips, malar region, etc. ) and can also be introduced in the following areas of the body: chest, hands, buttocks, outer labia and penis. Autologous fat is also ideal for correcting dimples after unsuccessful liposuctions.

1. What is an autologous fat graft?

In contrast to organ transplantation, in autologous fat grafting fat is removed from a body site (e.g. stomach, thighs, etc.) and introduced in a different body site (e.g. lips, eye rings, etc.). It is therefore the transplantation of one’s own body tissue, whereas organ transplantation is the introduction of foreign tissue into the body.

2. For what can one’s own fat be used?

The autologous fat transplantation is used primarily for cosmetic corrections in the face. These include lip augmentation, elimination of the nasolabial folds, filling of dark circles or general rejuvenation of the face. Fat transplantation has been used for several years, but since the discovery of stem cells in fat tissues (ADSC), it is also used to improve damaged skin, correction of larger tissue defects and for beautifying scars.

3. What are the properties of the stem cells of the adipose tissue?

Stem cells in the fat tissue (ADSC) have the useful property of being able to evolve as a function of their environment in different cell types (niche theory). These include inter alia skin tissue, connective tissue, blood cells, blood vessels and fat cells. Just this property allows significant improvement in the appearance of irradiated skin, burn scars and scars in general.

4. How is the transplanted fat biodegraded by the body?

The purpose of autologous fat transplantation is to achieve noticeable fat healing in the recipient site. The fat cells will be re-vascularized and survive in the new region. The amount of take varies between 30-80%, so several sessions may be necessary to achieve the desired effect. Healed fat will not disintegrate, and the result is permanent.

5. If more procedures are planned, how much time should elapse between the surgery?

There should be at least two months between procedures.

6. Can fat grafting be used to replace implants in a breast augmentation?

Breast augmentation with autologous fat transplantation is in its early stage and still limited, however; technically the road has been paved. Amazing results can already be achieved with the enrichment of the fat tissue with ADSC (stem cells of adipose tissue), the expansion of the breast with a suction cup (BRAVA method) and multi-layer placement of the fat. However, breast augmentation with autologous fat transfer still has its limits.The current ceiling is approximately 150 – 250 ml/chest. This also implies that between 500 – 1000 ml of pure fat has to be taken, a lot of which is not available in every woman.

7. Can fat grafting be used to replace a facelift?

No. Characteristic of the aging process is a loss of subcutaneous fat and the associated volume loss in the face. Fat grafting re-introduces volume in the face. A facelift corrects excess skin and lifts the sunken structures. Therefore, autologous fat transplant is regarded as an ideal complement to a facelift and the two procedures are often performed together.

8. Which is better, body fat or artificial fillers?

In my view, one’s own body fat should be given preference. Initially operating efforts & costs are somewhat greater, however, in the long term fat grafting is more cost effective. Fillers such as Hyaluronic acid are metabolized by the body within 4 to 6 months; therefore it must be repeated regularly. In fat transplantation the volume gain achieved is permanent, the healing rate of transplanted fat however varies between 30-80%, and. In addition, there can be no allergic reactions and/or intolerances of any kind, because it is the body’s own tissues.

9. How complex is an autologous fat transplant?

The transfer of small amounts of fat (up to 100ml) can almost always be performed on an outpatient basis and under local anesthesia. For larger quantities or if fat is to be transplanted into many regions, a light sedation is recommended. An average autologous fat transplantation (dark circles, nasolabial folds or lips) lasts 20-25minutes and needs about 10ml of patients’ own fat.

10. What complications can occur?

Complications associated with autologous fat transplantation at the recipient site are extremely rare. Medical complications such as local infections are easily manageable. Improper handling may result in oil cysts and calcifications. Other complications can be asymmetry, lumps, bulges, bumps and displacements. Cosmetic complications can almost always be completely corrected. Complications with fat removal are negligible at low suction.

11. Is there any permanent scarring after autologous fat transplantation?

An incision of 1-2mm in length is necessary for the transfer of fat and generally heals without a trace, suturing is not necessary. The scars in the donor region are roughly the same size and therefore also difficult to see.

12. As of when are you “socially acceptable” after autologous fat transplantation?

Depending on the recipient region, varying degrees of swelling can occur for several days but will usually subside after a week at the latest. For minor corrections no abnormalities should be visible within 1-2 days.

13. What are the long-term results after autologous fat transplantation?

In general, long-term results are excellent. Additional procedures may be performed at any time and as often as necessary.
