Introduction Buttock augmentation is a plastic surgery procedure that enhances smaller and flatter buttocks by increasing their size or adding projection and shape to them. Every year, thousands of women get buttock augmentation in the US alone with the goal to appear more feminine and aesthetically appealing. Fortunately, the procedure has a history of delivering impressive outcomes, and most patients who undergo the procedure report being happy with the results. Many people who want to undergo buttock augmentation want to know what options they have to achieve the desired results. The buttocks can be augmented with two methods: by using implants or through fat transfer. If you are considering buttock augmentation, you might be wondering as to which of these procedures is best for you and which one is more invasive. Buttock augmentation with implants: How invasive is it? As you can deduce from the name, butt implant surgery involves the placing of external devices called implants inside the buttocks. As such, this procedure is more invasive than fat transfer surgery. Buttock implant surgery is recommended for women who want to get large buttocks instead of shapelier and mildly projected behinds. Butt implants are available in different size options. How invasive the procedure can be will also depend on the size of the implant. If you choose a large implant, it will require a longer and larger incision to be placed into the buttocks. It is for this reason that patients are advised to select their implant size carefully. Bear in mind that bigger buttocks are not always better. The size of implant best for you depends on various factors, such as your buttock dimensions, your expectations from the surgery, and the plastic surgeon’s expert judgment. The plastic surgeon can tell you best as to what implant size is suitable for you and can help you achieve your goals. To understand how invasive buttock implant surgery can be, you need to know how the procedure is performed. Once the implants are selected during the pre-operative consultation, the plastic surgeon will provide you a date for the surgery along with instructions to prepare for the procedure. On the day of the operation, the plastic surgeon will place incisions on the buttocks. The incisions are larger though, but the size of the incision also depends on the size of the implants. The larger the implant, the larger will be the incision. Keep in mind that the incisions will ultimately change into scars over time, so it is vital for the patient to discuss it with the surgeon during the pre-operative consultation. A good plastic surgeon will do his best to use as few incisions possible and place them where the scars can be hidden or camouflaged. For example, in most cases, the incisions are made in the division between the buttocks so that the resulting scars are not visible. Once the incisions are made, the plastic surgeon will insert the implant into the buttocks through the incisions and then place them under or within the gluteal muscle. He will then suture and close the incisions. The invasive nature of the buttock implant surgery makes it riskier than fat transfer surgery. For example, the incisions are subject to splitting if you are careless during recovery. If the incisions split open, you can experience excessive bleeding, infection, and abnormal scarring. Furthermore, the incisions leave scars on the buttocks. Your body will produce an increased amount of collagen after the surgery to seal the incisions, which will result in scarring. In most cases, the scars fade and become less visible within one year after the procedure; however, abnormal scars may develop that look aesthetically unpleasant, raised, rough, and more visible. Despite being more invasive and relatively risky, buttock implant surgery remains to be a popular plastic surgery procedure. If your plastic surgeon is board-certified and has extensive experience, you can rest assured that the incisions will heal properly and you will achieve your aesthetic goals safely. Furthermore, buttock implant surgery is your only option if you want to get considerably bigger buttocks because fat transfer surgery does not make the buttocks considerably fuller or bigger. Fat transfer to the buttocks: How invasive is it? Fat transfer is the second plastic surgery method to augment the booty. However, it is not as invasive as buttock implant surgery. As the name suggests, this procedure involves transferring fat to your buttocks instead of foreign objects like implants. The fat used to augment your buttocks with this method comes from your body. This procedure is best for you if you want to add mild projection and more shape to your backside. It is not for people who want to get bigger buttocks. The good news is that with this procedure, you will not get incisions and hence no scars on your buttocks. Instead, it involves tiny incisions on the fat donor sites. To qualify for the fat transfer surgery, you need to have excess fat in your body. Fat transfer surgery involves different steps. The main steps involve fat harvesting, fat processing, and fat grafting. Fat transfer to the buttocks is also a significant procedure; however, since it is not as invasive as the butt implant surgery, the risks are relatively lower. Furthermore, you will get entirely natural results. Fat transfer to the buttocks starts with anesthesia administration. The procedure is performed under IV sedation with local anesthesia or under general anesthesia. After a board-certified anesthesiologist administers the anesthesia, the plastic surgeon will begin the operation by making tiny incisions on the fat donor areas. The common fat donor sites include the abdomen, sides, love handles, and upper back. The plastic surgeon will perform liposuction on these localized areas to collect fat for transfer to your buttocks. During liposuction, the plastic surgeon will insert a hollow tube called a cannula into the fat donor area and then move the cannula back and forth to release the fat cells from the surrounding tissues. He will then remove the fat from those areas with the help of a syringe or a low-pressure suction pump. This process is called fat harvesting. After enough fat is removed from your body, the surgeon will suture the incisions. In the second step, the plastic surgeon will treat the collected fat in a centrifuge with the goal to process and purify the fat. During this process, the plastic surgeon will remove the impurities from the fat collection. This step is crucial to the achievement of the desired aesthetic results. If this step is not performed correctly and with no attention to detail, you may not achieve sustainable outcomes. The plastic surgeon will also remove the dead, damaged fat cells and fluids and blood from the fat collection. After the fat is purified, the plastic surgeon will implement the most critical step of the surgery, i.e., fat grafting. Fat grafting means injecting the fat into the booty. Fortunately, there is no need to make incisions on the buttocks to transfer the fat. This is one of the major reasons why the surgery is less invasive and why more women get this procedure. Instead of using incisions, the plastic surgeon will use a special needle to pick the fat cells and then carefully inject them into the buttocks. Even though this step is time-consuming and involves more artistry, it does not leave incisions and hence no scars on the buttocks. Once the fat cells are injected into the buttocks, the surgery will come to an end. The fat cells injected into the buttocks require time to get a blood supply, nurture and expand, and deliver you the desired improvements. Once the results emerge after many weeks and even months, your buttocks will look projected, smooth, natural, and sexy. The good news is that all these improvements come without incisions and scars on the buttocks. However, to get satisfactory results, you must choose only a board-certified plastic surgeon with experience in fat transfer to the buttocks to perform the procedure. Conclusion Many women wanting to augment their buttocks often get confused when it comes to choosing between implants and fat transfer. One of the questions they ask is which of the procedures is more invasive. It is vital for the patient to be aware of the invasive nature of both procedures. During the pre-operative consultation, you must ask your surgeon as to which procedure is more invasive and what are the pros and cons of each. There is no doubt that the buttock implant surgery is more invasive than fat transfer surgery. It involves the placement of external objects into your buttocks through more extensive incisions. In this article, I have compared the invasive nature of both procedures.
