Introduction Buttock augmentation with fat transfer is now a fully-established plastic surgery procedure. It is used to add mild projection for women who have buttocks that lack projection and shape. There is no doubt that the buttocks are among the most vital aesthetic areas of the female body as they define your femininity, beauty, and body outline. Fat transfer uses a combo of liposuction and fat grafting to contour the booty. Some years ago, fat transfer was criticized for delivering temporary aesthetic improvements due to fat absorption by the patient’s body and surgical problems. However, many developments have been made that have increased the life of the achieved results. Let’s discuss how long the fat injected into your buttocks may survive after the procedure. How long does fat survive after being injected into the buttocks? This is one of the most important and common questions about fat transfer surgery, which is also called the Brazilian butt lift. While it may seem easy to remove the excess fat from your body and then inject it into your booty, the procedure is complicated as the surgeon has to make sure the fat survives after being transferred to the buttocks. Despite the developments made in the field of plastic surgery, there is no assurance that 100 percent of the fat injected into your buttocks will survive. There are some surgeons and surgical facilities that promise patients that more than 95 percent of the fat grafts will survive, but it is hard not to be cynical about those promises. The first fact is that it is challenging to determine as to how much fat will survive after being injected into the buttocks. During the pre-operative consultation, you can ask the surgeon to show you before and after pictures of patients that he has treated for fat transfer to the buttocks. In most cases, you will see that some of the fat is lost in the weeks and months following the procedure. In most cases, the results take around three months to become stable. As such, you can ask the surgeon for pictures taken a few weeks after the surgery and three months after the surgery. Most plastic surgeons agree that around 15 to 20 percent of the fat injected in the buttocks is lost after the procedure. Keep in mind that fat transfer is a delicate operation and not all the fat grafts will survive. The fat survival rate depends on many factors, including how the surgery was performed and how careful the patient was during the recovery period and afterward. When the fat volume in the buttocks changes, it affects the outcomes of the procedure. When fat is transferred to the buttocks, there is no guarantee that it will remain there permanently. The fat survival also depends on the specific areas where the fat is injected and how well and how soon blood supply has been established in the area. If your plastic surgeon is board-certified and experienced, a good portion of the fat will survive and remain permanently with you. A good surgeon will do whatever is possible to decrease the amount of fat loss after the procedure. There are many things in the hands of the plastic surgeon that can maximum the fat survival rate, and there are certain things that the patient can do to ensure that maximum fat survives after being injected into the booty. How to ensure long-lasting and maximum fat survival rate Fat transfer is a major operation. It is performed under general anesthesia or IV sedation with local anesthesia. During the procedure, the surgeon will perform liposuction on the fat donor areas to remove the excess fat from those areas. The fat is then purified by spinning it in a centrifuge. In the last step, the surgeon will carefully inject the fat into the booty. Now, the plastic surgeon can perform the procedure in a way that would ensure that most of the fat survives for a maximum time after the surgery. Below are what the surgeon and patient can do to achieve this: Careful fat extraction The key to prolonging fat survival after the Brazilian butt lift is to ensure the careful removal of the fat from the fat donor sites so that maximum fat cells are preserved. When liposuction is performed carelessly, a majority of the fat cells will be damaged. When the damaged fat cells are injected into the booty, they will not survive for long. The best way to extract the fat is through tumescent liposuction. Laser and ultrasound assisted liposuction methods should be avoided. Some fat donor areas like the love handles and lower back store excess fat that have a higher survival rate. Fat processing Besides fat extraction, how well the fat has been processed and purified also determines how long the fat will survive after being injected into the buttocks. If the purification is not done correctly, the damaged and dead fat cells will make their way to the buttocks. These fat cells will not survive, which can lead to failure of the surgery. The fat must be treated in a centrifuge and spun at high speed so that all of the impurities, blood, fluids, and dead and damaged fat cells are removed. The key to prolonging the fat survival rate is to use only the living and healthy fat cells for transfer to the buttocks. Fat grafting Fat grafting or fat injection into the buttocks is also an essential element that plays a vital role in the longevity of the results. The plastic surgeon will inject the fat cells into your buttocks with a special needle. The key here is to inject the fat in a way that mimics the existing fat in your buttocks. To achieve this, the surgeon must use micro-droplets of the fat and carefully and meticulously inject them into the buttocks. When this protocol is followed, it also makes the skin smooth and toned and the buttocks will appear natural. When the micro-droplet method is employed, it forms tiny sections of fat where the blood vessels can develop. The blood vessels will supply blood to the fat cells, which will increase their survival rate. Patient responsibility How long the fat will survive after being injected into the buttocks not only depends on the surgeon but also the patient. The patient must follow the post-op instructions entirely. You must avoid activities that can apply pressure or strain to the buttocks for three weeks following the operation. The fat cells must be vascularized before you can start to sit and sleep on your back. If the fat cells are not vascularized, the pressure to the buttocks can damage the fat cells, which will decrease fat survival. Even when you resume sitting after the procedure, you must keep a soft cushion under your buttocks and a rolled towel under your hamstring muscle. The plastic surgeon will also advise you to wear compression garments for many weeks after the procedure. The compression garments are designed to keep your newly contoured buttocks in place until the fat cells are strong enough to hold your buttocks in the new position. Typically, patients are required to wear the compression garments for six weeks after the procedure. These garments also reduce the swelling and speed up the recovery. One of the primary elements that shrink the fat in the buttocks is massive weight loss. The fat injected into your buttocks will behave in the same way as the fat in other areas of your body. This means that weight loss will affect it in the same manner as it does the fat in other areas of your body. When the patient undergoes massive weight loss through diet and exercise, the fat cells in your buttocks will shrink and liquefy. This will lead to a reversal of the results. To avoid this condition, the patient must avoid massive weight loss after the procedure. Conclusion Fat transfer to the buttocks is an effective plastic surgery procedure that adds shape and projection to the booty. During the procedure, the surgeon will remove the excess fat from your body, purify the fat, and then carefully inject the fat into the buttocks. Many patients ask how long the fat will survive after being transferred to the buttocks. The fat survival depends on many factors that have been explained above. But almost all surgeons agree that not 100 percent of the fat cells will survive after the procedure. About 15 to 20 percent of the fat volume may be lost. Of course, the patient can opt to get touch-up fat injections after the primary operation to make up for the lost fat.
