Fat Transfer to Buttocks

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.

The amount of fat that can be transferred to your buttocks during a Brazilian Butt Lift (BBL) depends on your body type, the fat available for harvesting, and your aesthetic goals. For patients with more body fat, surgeons can typically harvest between 500 to 1,500 cc per side, though some patients may be able to receive even larger amounts. On average, around 1 to 2 liters of fat in total can be transferred, but the exact amount will depend on individual factors like skin elasticity and the surgeon’s technique. It’s important to note that about 30% to 50% of the fat may not "take" or reabsorb, which is why it’s common to err on the side of transferring a bit more fat to account for this loss.
Patients who are interested in achieving significant volume increases should consult with an experienced plastic surgeon who can evaluate their body composition, skin elasticity, and desired outcome. A plastic surgeon will consider how much fat is available for removal through liposuction, typically from the abdomen, thighs, or flanks, and will then determine the appropriate amount to inject into the buttocks to achieve a proportionate and natural-looking result. Always keep in mind that while more fat transfer might seem like a good idea for a larger result, there are limits to how much fat can be harvested from liposuction and also how much fat the buttocks can safely accommodate.

Depending on which state you get the liposuction, the limit for liposuction can be either 4000cc or 5000cc. In my hands, approximately 80% of this fat is usable for transfer. Ideally, 80% of 5000cc here in Nevada would result in 4000cc of transferrable fat harvested, meaning 2000cc of fat into each buttock. Approximately 30% of that fat will be reabsorbed resulting in a final total of 1400cc in each buttock. This volume will certainly make a big difference in the appearance for your buttocks.

Thank you for your question. 50-60% will survive if it is grafted appropriately. I would advise you to schedule a consultation with a board certified plastic surgeon for a detailed examination to discuss all possible treatment options and what your expectations are. 

Thanks for your question. It is hard to advice you without seeing photos or doing an in person evaluation. When planning a Brazilian butt lift, patients can look forward to a double benefit: reducing areas of unwanted fat while gaining a perkier, rounded posterior.  Each procedure must be planned according to the individual needs of patients, harvesting fat from target areas of the torso, thighs or knees and transferring it to create smooth, attractive contours optimized for each person.The amount of fat transferred depends on the quantity available and the extent of buttock augmentation each patient desires.  Sufficient body fat for a buttock augmentation is very patient-specific, depending on an individual’s body shape and proportions as well as their expectations.  That said, you definitely have to choose your surgeon correctly and make sure that he/she has the training and experience to meet your goals with absolute safety.  Best is a Board Certified Plastic Surgeon with specialized expertise in this procedure.

There are 2 areas of limitation when it comes to how large your butt can be after surgery...1) how much fat can we take, and 2) how much fat can we put in.
For the first part, even though you did not post photos, based on your height and weight you would have plenty of fat to be able to take in my opinion. The relative limit on how much can be removed and send you home the same day safely is about 5 liters of liposuction/fat. I think you would easily be able to get to this upper limit based on your height and weight.
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!

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.

The amount of fat that can be transferred in a BBL depends on how much fat the patient has to harvest and the amount of space there is to move the fat into.

Great question!  Without seeing you it is difficult to make an accurate assessment.  However as a general rule, the maximum amount of liposuction that can be performed in an outpatient setting, is around 5 liters due to the vast amount of fluid shift.  After filtration of the fluid, blood, devitalized fat cells, and lipids, generally you are left with about 2 liters of mature viable fat for injection.  Which means 1 liter to each side - which is a lot.  Take into account that you will loose anywhere from 20-40% of the volume so now we are at about 600-800cc's that will remain...that is with a maximum of 5 liter of liposuction.  If you have more than 5 liters of fat, then you may need to undergo this procedure a second time in order to harvest more fat for injection.Best of luck and hope this information helps!- Dr. Roger Tsai  @DrRogerTsai

Thank you very much for sharing your concerns with us, to give you an accurate answer it’s necessary to do the physical exam to evaluate your skin and sub cutaneous butt tissue quality, saggiest, stretchness, tone and other many characteristics, but in average in a patient with your weight a height the BBL can get round 2,000cc’s of fat.

The question of the perfect weight as it relates to BBL is fast becoming one of the most commonly posted questions in the RealSelf community. While it is true BBL is a weight sensitive procedure (in the sense that you need fat to achieve your result), it is never a good idea to pursue short term changes for surgery.
While there is no absolute number (lbs.) in terms of weight for undergoing liposuction with autologous fat transfer, the optimal candidate has reached a healthy and stable weight (preferably with a BMI less than 30, which is associated with a lower incidence of complications).
Potential candidates should also have adequate fat reserves for transfer. This becomes especially important when one considers the anticipated rate of fat resorption and graft loss. I typically recommened patients aim for at least 500 cc transferred per cheek. This would amount to 1 liter of fat (not lipoaspirate) after processing. Candidates with inadequate fat reserves are likely to be disappointed with their ultimate volume once healing is complete. 
As always, discuss your concerns with a board certified plastic surgeon (ABPS).
