I have had much experience in fat grafting to the buttocks for Brazillian Buttock Augmentation in Los Angeles. I have had patients from 105 lbs to more than 200 lbs. the best results were in those that had much fat available for harvesting. In my experience depending on the technique of harvesting, processing, and injecting the fat, at least 90% of the volume can stay. I have had several patients who have retained more than 90% of their buttock volume despite having had pregnacies, working out, and after more than 5 years.
2. You buttock's structural anatomy is also an important factor.  A V-shaped buttock typically requires more fat transfer to achieve a satisfactory improvement than an A-shaped buttock.  Transferred fat cells need to grow their own blood supply from the surrounding buttock tissues in order to survive.  In order for this to happen, the transferred fat cells need to be gently interwoven between your buttocks' living cells to survive.  Therefore, each person's buttocks can only receive a certain amount of fat, and exceeding that amount will not be effective.  A generous amount of fat is typically transferred at the time of surgery, knowing that some of the fat will go away during the recovery period.
During your initial consultation, you will have the opportunity to discuss what you want to achieve. Your surgeon will evaluate you as a candidate for fat grafting and clarify what fat grafting can do for you. Once the surgeon understands your goals, he or she may suggest additional or related procedures. It is important to be completely honest during the consultation. Bring several photos of yourself at an earlier age; they may serve as a good point of reference for discussing your goals. It’s a good idea to be fully prepared to answer these questions:
After reviewing the medical data, the U.S. Food and Drug Administration concluded that TDA-induced breast cancer was an infinitesimal health-risk to women with breast implants, and did not justify legally requiring physicians to explain the matter to their patients. In the event, polyurethane-coated breast implants remain in plastic surgery practice in Europe and in South America; and no manufacturer has sought FDA approval for medical sales of such breast implants in the U.S.[93] 

Fat transfer breast augmentation has a few important limitations. First, fat transfer is typically limited to approximately one cup size increase in breast size. Second, the transferred fat may be absorbed again by the body. Third, it is more expensive because of the extra time involved in harvesting and processing donor fat as well as possible need for a special vacuum bra device. This option is best reserved for women who desire a modest increase in size without using an implant.
Implants come in various sizes, and your surgeon will guide you on choosing the right size to help you achieve the look you desire. In addition, your surgeon will help you decide whether you want a more natural, teardrop shape or a more rounded look. Implants also come with either smooth our textured shell surfaces, and your surgeon will help you decide which is best for you.
For the second part....it depends where your butt is starting at. There is a point in which there is too much pressure in the butt that no more fat can really be injected. Pressure kills the fat cells (which is why you cannot sit on the butt for a few weeks after surgery). It also means that we cannot just keep injecting if the gluteus has fully expanded and is not able to take any more. If you are starting with a small butt.....there is a smaller limit. If you are starting with a medium sized butt.....there is a bigger limit. I like to use power assisted "vibration expansion filling" to really push the boundaries of how much fat can be injected into the buttocks. This helps to expand the buttocks on the table and get more fat into more stubborn areas. Typically, even for smaller girls, I will inject at least 1000ml per side (and up to 1600ml for larger girls). After this, as you have probably read, 30-50% of the fat will either reabsorb or "not take". However, with the removal of a large amount of fat around your midsection combined with careful technique and contouring of the butt and hips, we can make a very large difference in your overall proportion. Best of luck to you!

Because you’re injecting your body with something produced by your body, some people consider it “natural” plastic surgery, and it’s increasing in popularity. Breast augmentation using fat transfer increased 72 percent in 2016 while buttock augmentation using fat transfer increased by 26 percent, according to the American Society of Plastic Surgeons.
Case 75: Getting a severely crooked nose as close to perfectly straight as possible is one of the hardest things to accomplish in rhinoplasty. Our extensive experience at Profiles with traumatic noses has us well positioned to treat these difficult cases and achieve a nasal contour that is no longer a focal point but now blends with the rest of her features.
Case 72: This patient had sustained a nasal fracture that caused a significant deviation of her nose. The fracture was corrected along with a septoplasty to improve breathing. Loss of tip support after the injury made her hump look more prominent and her tip felt more droopy. The bump was smoothened and her tip angulation restored to create the softer, more feminine profile she wanted. At the same time, fat transfer to the cheek and under eye area and subtle neck liposuction substantially improved the flat cheek and mid-face contour that previously made her feel hollowed and tired looking without makeup.
Make sure your cosmetic surgeon is board certified; this ensures that he or she is specifically trained and experienced in cosmetic surgery and that your procedure will take place in an accredited facility, which is essential for your safety. Finally, don’t choose a cosmetic surgeon based on price alone. Your safety & results are too important. Most cosmetic surgeons offer financing options to help patients budget procedure costs.
the second technological development was a polyurethane foam coating for the shell of the breast implant; the coating reduced the incidence of capsular contracture, by causing an inflammatory reaction that impeded the formation of a capsule of fibrous collagen tissue around the breast implant. Nevertheless, despite that prophylactic measure, the medical use of polyurethane-coated breast implants was briefly discontinued, because of the potential health-risk posed by 2,4-toluenediamine (TDA), a carcinogenic by-product of the chemical breakdown of the polyurethane foam coating of the breast implant.[92]

Dr. Kolker then laid out his surgical plan for me: He'd perform an open rhinoplasty, explaining that the difference between an open and closed procedure amounts to a small incision on the underside of the columella (that skinny strip of skin between the nostrils), which can be seen only from below and fades rapidly. Both procedures require incisions inside the nose, but an open rhinoplasty adds that small columellar incision.
Inframammary: an incision made to the inframammary fold (natural crease under your breast), which affords maximal access for precise dissection of the tissues and emplacement of the breast implants. It is the preferred surgical technique for emplacing silicone-gel implants, because it better exposes the breast tissue–pectoralis muscle interface; yet, IMF implantation can produce thicker, slightly more visible surgical scars.
Case 89: This patient had broken her nose with consequent severe loss of tip support, tip rounding, crookedness, and a traumatic bump. In this case, a lateral crural overlay technique was used to reduce and lift the tip along with a septal extension to help with support and straightening which has improved tremendously as seen on the base view. Even though she’s still swollen in these early photos, she already has a great result and it’s only going to get better.
No. Rhinoplasty is a challenging operation. This is due to several factors. First, the nose is a complicated 3D shape that is in the middle of the face. Changes made during rhinoplasty are often very small. But these changes can make a major difference in the way the nose looks and functions. Because these changes are small, so is the margin for error.
When a silicone breast implant ruptures it usually does not deflate, yet the filler gel does leak from it, which can migrate to the implant pocket; therefore, an intracapsular rupture (in-capsule leak) can become an extracapsular rupture (out-of-capsule leak), and each occurrence is resolved by explantation. Although the leaked silicone filler-gel can migrate from the chest tissues to elsewhere in the woman's body, most clinical complications are limited to the breast and armpit areas, usually manifested as granulomas (inflammatory nodules) and axillary lymphadenopathy (enlarged lymph glands in the armpit area).[41][42][43]
Case 72: This patient had sustained a nasal fracture that caused a significant deviation of her nose. The fracture was corrected along with a septoplasty to improve breathing. Loss of tip support after the injury made her hump look more prominent and her tip felt more droopy. The bump was smoothened and her tip angulation restored to create the softer, more feminine profile she wanted. At the same time, fat transfer to the cheek and under eye area and subtle neck liposuction substantially improved the flat cheek and mid-face contour that previously made her feel hollowed and tired looking without makeup.
MENTOR® MemoryGel® Breast Implants, MENTOR® MemoryShape® Breast Implants, and MENTOR® Saline-filled Breast Implants are indicated for breast augmentation in women (at least 22 years old for MemoryGel® Implants and MemoryShape® Implants, and 18 years old for Saline Implants) or for breast reconstruction. Breast implant surgery should not be performed in women with active infection anywhere in their body, with existing cancer or pre-cancer of their breast who have not received adequate treatment for those conditions, or who are currently pregnant or nursing.
Deciding how much fat to transfer to a patient’s buttocks is a decision made by the surgeon that takes safety, cosmetic result, and patient’s goals into account. I recommend reviewing your goals of surgery, by showing photos, or performing Vectra imaging in office, with your surgeon and listening to their recommendations for the safest, best-looking results possible.
