What does it involve?
Autologous (patients’ own) fat transfer or lipomodelling is an alternative choice for breast augmentation and body contouring. In this technique, fat cells can be removed surgically using liposuction technique. After infiltration of local anaesthetic and saline solution, the patient’s fat cells are removed using a cannula through small stab incisions around a few millimeters in size. The fat cells are usually discarded in liposuction however, when it comes to breast augmentation and body contouring using fat transfer, the fat can be injected into another part of the body. The two most common areas for volume augmentation using fat transfer are the breast and facial region. Due to the risk of complications, fat transfer to the buttock region has been halted in UK.
Fat injections into breasts have been around over the last 20 years and with improvements in technique, it has continued to gain popularity. It is most commonly used for contour defects and shape transformation in patients who have had breast reconstruction. The use of fat transfer has also been noted to improve skin and tissue quality after previous radiotherapy. With the current issues related to breast implants, the use of fat transfer in breast augmentation is gaining popularity and some patients are interested in exploring alternative options.
What are the advantages?
There are a number of advantages associated with fat transfer or lipomodelling breast augmentation compared with implant augmentation. Unlike implant augmentation where an incision has to be made for the insertion of the implant, fat transfer involves fat being injected through very small 1-2mm holes using syringes and cannulae, which leave scars that are inconspicuous once settled. After the swelling has reduced and the injected fat revascularized, the result of the augmentation is permanent. The fat in the breast now behaves like other fatty tissue and can change with weight, hormones and age. This means no further surgery is required except if the patient requires further volume augmentation. This is in contrast to implant augmentation where the implant is likely to require an exchange at some point in the future. One thing to bear in mind is that with the fat transfer technique, patients will need to have an excess of fatty tissue that can be harvested from their abdomen, thigh and back and therefore, may not suit all patients.
The more common technique of implant augmentation is still more popular than fat transfer or lipomodelling. Implant augmentation uses either a silicone- or saline filled implant that is inserted into the breast pocket through a small incision. Since the implant is manufactured, liposuction is not needed and thus the post-operative discomfort is less and only limited to the breast region. Since the volume of implant is limited to skin tone and the patients’ breast footprint, it simply means a bigger volume increment can be attained in a single operation in comparison to fat transfer. However, large implant augmentation can produce a very unnatural appearance with excess lateral projection, excessive upper pole fullness and animation in those patients with submuscular implant placement. Stretching of the breast tissue and skin can lead to skin rippling and striae (stretch marks). It is important to realize implants are not permanent and will need to be exchanged at some point in time. There are issues that need to be clarified before proceeding with implant augmentation and your surgeon will explain those to you.
Breast augmentation using fat transfer and implants are not mutually exclusive and could be carried out in conjunction with each other. This is known as Hybrid augmentation, where the implant provides a certain degree of volume augmentation and then fat transfer can then be used to increase the soft tissue coverage of the implant and in some cases, to increase medial or upper pole fullness. The volume produced by fat transfer can also mean a smaller implant being employed and help to increase the overall natural appearance of the breast.
Of course, the choice of technique to achieve volume augmentation using fat or implants is a personal one. It is important to have a thorough consultation with your Plastic Surgeon to discuss your wishes and any concerns you may have and that should help you to make the right decision.
