Introduction
Autologous fat transplantation for breast augmentation has gained significant popularity in recent years, offering a natural alternative to traditional breast implants. In Albany, the demand for this procedure has grown as more women seek safe, effective, and aesthetically pleasing ways to enhance their breast size and shape. This article will delve into the various aspects of autologous fat transplantation and filling breast augmentation, including its techniques, safety, efficacy, complications, and patient satisfaction, while also considering the role of plastic hospitals in Albany.
Autologous Fat Transplantation: An Overview
Historical Development
Autologous fat injection was first described roughly a century ago and has been used in surgery ever since. In the context of breast surgery, it has evolved over time. Initially, in 1893, it was used for the repair of facial defects by Neubauer. Later, in 1895, Czerny used fat grafts for the first time to repair a post - mastectomy defect. However, it faced restrictions in the past. In 1987, the American Society of Plastic and Reconstructive Surgeons disapproved of autologous fat injection in breast augmentation due to concerns about graft resorption, calcification, and interference with breast cancer detection. But nearly a decade later, Coleman introduced a new, refined technique of fat aspiration, purification, and injection that greatly improved graft survival and reduced the rate of complications. By 2009, the American Society of Plastic Surgeons reversed its recommendation against the procedure.
Advantages of Autologous Fat Transplantation for Breast Augmentation
- Natural Appearance and Feel: Since the fat is taken from the patient's own body, the results tend to look and feel more natural compared to breast implants. The augmented breasts have a softer texture and can blend seamlessly with the rest of the body's natural contours.
- Minimal Foreign Body Reaction: Unlike breast implants, which are made of foreign materials and can potentially cause foreign body reactions, autologous fat is biocompatible. It reduces the risk of complications associated with foreign materials, such as capsular contracture, which can occur with silicone or saline implants.
- Dual Benefit of Body Contouring: In addition to breast augmentation, the procedure allows for body contouring. Fat is harvested from areas where the patient has excess fat, such as the abdomen, thighs, or hips. This results in a slimmer appearance in the donor areas while enhancing the breasts.
Techniques of Autologous Fat Transplantation for Breast Augmentation
Fat Harvesting
There are several methods for fat harvesting, each with its own characteristics. The most common donor sites are the abdominal fat, greater trochanteric region (saddle bags), and the inside of the thighs and knees.
- Vacuum Aspiration or Syringe Aspiration: These are frequently used methods. The “wet” technique involves the injection of a tumescent fluid consisting of NaCl, epinephrine, and a local anesthetic drug, such as Klein solution. This technique helps to reduce bleeding and pain during liposuction. However, the shear stress exerted on harvested fat can decrease adipocyte viability. An alternative “dry” method without the tumescent fluid can also be used, and the cell viability in samples harvested by this method has been found to be similar to that of the “wet” method. But the “dry” technique may lead to a greater requirement for analgesics.
- Water - Jet Assisted Liposuction: This method gently flushes the fat out of the tissue by a water jet. It leads to a higher viability of the lipoaspirate and improved rates of survival of the fat cells in comparison with common liposuction methods. For example, in a study of autologous fat cell transplantation for breast augmentation, a double - lumen cannula with a length of 25 cm and a diameter of 3.8 mm was used. The pressure was limited to a maximum of − 0.55 bar to handle the fat cells as gently as possible, and the adipocytes were flushed out of their extracellular matrix with a pulsating water jet.
Fat Processing
After harvesting, the fat needs to be processed to remove impurities and ensure a higher concentration of viable adipocytes.
- Centrifugation: A widely used protocol is the centrifugation described by Coleman. Once the fat is harvested, the fat syringes are centrifuged at 3000 rpm for 3 minutes. After centrifugation, the lipoaspirate is separated into four layers: the oily fraction, the watery fraction, a cell pellet on the bottom, and purified fat between the oily and watery fractions. The purified fat is then used for injection.
- Washing: The harvested fat can be washed with normal saline or 5% glucose solution to remove blood, the oily fraction, and cellular debris from the aspirated fat. However, washing can also destroy the microenvironment of the cells, including collagens, vessels, proteins, proteases, enzymes, and electrolytes.
- Decantation: This is the least popular technique. It uses gravity to precipitate the cellular component from the oily and watery components.
Fat Injection
The way fat is injected into the breast is crucial for its survival and the final outcome of the augmentation.
- Injection Planes: There are different injection planes in the breast, such as the subcutaneous, subglandular, and retropectoral planes. A preliminary exploratory study randomly assigned 40 female patients requiring breast augmentation with fat grafting into two groups. The retromammary group received 2/3 fat into the retromammary space and the other 1/3 into the subcutaneous and retropectoral planes, while the retropectoral group received 2/3 fat into the retropectoral plane and the other 1/3 into the subcutaneous and retromammary planes. Although there was no significant difference in the retention rate after 6 months between the two groups, the retromammary group had a higher incidence of oil cyst formation than the retropectoral group, indicating that the retropectoral space may have great potential as a favorable recipient site.
- Injection Technique: Fat should be injected in a 3 - dimensional pattern to ensure even distribution. For example, in one method, the fat is transferred as a 2 mm “spaghetti shape” in a criss - cross pattern. The diameter of the infiltration cannula should be at least 18 gauge to avoid impairing the metabolic activity of the particles due to pressure during injection. The fat particle injections occur in the subcutaneous, subglandular, and interpectoral fat layer, but never in the mammary gland tissue.
Safety of Autologous Fat Transplantation for Breast Augmentation
Oncological Safety
One of the major concerns regarding autologous fat transplantation for breast augmentation is its oncological safety.
- Research Findings: There is currently no scientific evidence that fat grafting interferes with breast cancer detection. For example, in some studies, no conclusive evidence was found to show that fat grafting to the breast potentially interferes with breast cancer detection. In a review of multiple studies, the question of de novo cancer induction or accelerating growth of a pre - existing cancer by fat grafting has not been answered to date. Although there are some experimental studies suggesting that adipose tissue transfer may affect the formation, prognosis, and treatment of breast cancer, the clinical data are still insufficient to draw definite conclusions. For instance, in a case - controlled study comparing patients with breast cancer who had undergone fat grafting surgery with a control group, it was indicated that fat injection is an oncologically reliable method even in patients with breast cancer, but the study also pointed out that fat injections may present a risk in patients with intraepithelial neoplasia.
- Imaging and Detection: Imaging technologies such as ultrasound, mammography, and magnetic resonance imaging can identify the grafted fat tissue, microcalcifications, and suspicious lesions. Biopsies may be performed if needed for additional clarification. For example, a retrospective study of 20 patients with breast augmentation complications found that mammography can reveal mass and calcification in the breasts, and appropriate incisions and surgical treatments can be planned based on these findings.
General Complications
Although autologous fat transplantation for breast augmentation is generally considered safe, it can be associated with certain complications.
- Fat Necrosis and Calcification: Fat tissue that is not perfused can die and result in necrotic cysts and even calcifications. However, these complications can occur after any type of breast surgery. In a systematic review, it was reported that autologous fat transplantation can lead to fat necrosis and calcification, but not significantly more frequently than after reduction mammoplasty. The reported incidence of calcifications and oil cysts in the literature varies, with some studies suggesting a risk of up to 50%, while others describe a frequency of around 4.5%.
- Other Complications: These include palpable nodules, unsatisfactory results in terms of volume, shape, and/or symmetry, infections, dysaesthesia, lymphadenopathy, pain, haematoma, and poor fat graft survival. In a study of 1453 patients who underwent lipofilling of the breast, the most common complications were palpable nodules not requiring any surgical intervention (7%), unsatisfactory results in terms of volume, shape, and/or symmetry (3%), and infections (0.7%).
Efficacy of Autologous Fat Transplantation for Breast Augmentation
Fat Graft Survival
The survival of the fat graft is a key factor in determining the long - term efficacy of the procedure.
- Factors Affecting Survival: Several factors can influence fat graft survival. The source of the fat can play a role. Studies have shown that the grow - in rate is not significantly affected by the donor zone. However, factors such as the size of the fat graft, the surface - to - volume ratio, the technique of harvesting and processing, and the patient's health status can impact survival. Smaller grafts with a higher surface - to - volume ratio have an advantage over larger grafts, as a greater proportion of the graft is in contact with the graft bed, which facilitates revascularization. For example, initially, the graft survives via the direct diffusion of nutrients from plasma, and it takes between 24 hours and 4 days for the angiogenesis around the fat particles to begin.
- Survival Rates: The reported fat graft survival rates vary widely. Different studies have reported different survival rates depending on the techniques used and the patient population. For example, in a study using water - jet assisted liposuction for autologous fat transplantation for breast augmentation, the volumetric evaluations via magnetic resonance imaging showed that different authors found uptake rates ranging from 62% to 82%.
Patient Satisfaction
Patient satisfaction is an important measure of the efficacy of autologous fat transplantation for breast augmentation.
- Subjective Assessment: In a study of 300 autologous fat transplantations on 254 women, the results were assessed based on patient responses on a questionnaire. Overall, 35.9% of the patients defined the result as very good, 38.6% as good, 22.4% as satisfactory, and 3.1% as poor. Many patients appreciate the natural appearance and feel of the augmented breasts, as well as the dual benefit of body contouring.
- Objectives Measures: Objective measures such as the change in breast volume and contour can also be used to evaluate patient satisfaction. For example, in some studies, photos taken before and after the procedure were used for comparison, and the changes in breast volume were measured using techniques like 3D laser surface scanning or magnetic resonance imaging.
The Role of Plastic Hospitals in Albany
Quality of Services
Plastic hospitals in Albany play a crucial role in providing high - quality autologous fat transplantation and filling breast augmentation services.
- Experienced Surgeons: These hospitals should have plastic surgeons with extensive experience in performing autologous fat transplantation procedures. Experienced surgeons are more likely to achieve better results and minimize complications. For example, they are skilled in fat harvesting techniques that ensure a high viability of the harvested fat cells and in injecting the fat in a way that promotes its survival and a natural - looking outcome.
- Advanced Facilities: They need to be equipped with advanced facilities for fat harvesting, processing, and imaging. High - quality liposuction equipment, such as water - jet assisted liposuction devices, can improve the viability of the harvested fat. Imaging facilities like ultrasound, mammography, and magnetic resonance imaging are essential for preoperative assessment, postoperative monitoring, and detecting any potential complications.
Patient Care and Consultation
Good patient care and consultation are essential aspects of plastic hospitals in Albany.
- Pre - operative Consultation: During the pre - operative consultation, surgeons should thoroughly discuss the patient's goals, expectations, and medical history. They should provide detailed information about the procedure, including its risks, benefits, and limitations. For example, they need to inform patients about the possibility of fat resorption, complications, and the need for multiple sessions in some cases.
- Post - operative Care: After the procedure, proper post - operative care is crucial for the patient's recovery and the success of the augmentation. Plastic hospitals should provide clear instructions on wound care, activity restrictions, and follow - up appointments. They should also monitor the patient's progress closely to detect and address any complications in a timely manner.
