What is a buttock augmentation?
Buttocks augmentation is performed by grafting fat onto the buttocks of the patient or placement of silicone implants under the gluteous muscle. The volume of fat transferred to the buttocks from other areas of the body varies from 200 to 1000 cc per side. The volume increase is achieved by the transfer of living cells which continue to function as living fat cells when transferred to the buttocks. Because a percent of the fat cells transferred do not “take” there is not a strict 1:1 (volume increase : volume transferred). The majority survive and do well.
Why are buttock implants less frequently used?
Buttock implants have a higher infection rate and do not feel natural, like a fat-only augmentation does. They tend to feel harder due to the solid nature of the buttock implant. The volume increase is less than can be achieved with fat cell grafting. With implants there is a higher wound breakdown problem which can lead to implant extrusion. Implants made of silicone may have problems related to shifting or long-term scar capsule formulation. These problems do not occur with fat grafting. Implants can only be placed in one plane, usually under the muscle. Another drawback is that silicone buttock implants do not have the versatility of fat grafting which may be placed in multiple tissue planes. Correcting lateral buttock deficiencies is not possible with implants as it is with fat grafting. Small surface contour irregularities are easier to correct with fat grafting but often impossible to change with implants.

How is buttock augmentation performed?
Liposuction is first done to acquire the fat cells for grafting. In larger cases, where fat is removed circumferentially from the waist, this alone improves the waist to hip ratio making the buttocks appear larger with a small waist. Liposuction of the sacral area in the midline enhances buttock definition even before fat grafting. This occurs because the relative distance increases between the lowest point of the gluteal cleft and point of maximum buttock projection.
Fat may then be processed in different ways before grafting. The technique of centrifuging the fat, to separate it from fluids aspirated in the liposuction, gives the greatest number of fat cells. Other techniques where the liposuction aspirate is left to separate by standing or the “strainer” technique, leave more liquid to be injected. Liquid without fat cells does not give any long-lasting volume increase.
Dr. Hobbs uses the centrifuge technique exclusively to maximize the number of fat cells available. The injection of fat cells is done using a special technique that involves precise placement of the fat cells and ensures more grafted cells “take.” These fat cells surrounded by healthy, well-vascularized tissues increase the success rate. Placing small amounts of fat into many tissue planes provides soft buttocks with an even consistency. In larger buttock augmentations, 4 to 5 smaller openings are made on each side for injections in order to improve healing by reducing tissue trauma that would occur with only one or two openings. These openings are closed with dissolvable suture which means no suture removal is required.
What does a new augmented buttock feel like?
Initially, the entire area is abnormally firm due to swelling related to the surgery. Along with this may be some numbness that gradually improves as swelling subsides. In a few weeks, the buttocks will begin to feel like normal with more softness. The ability to sit without tenderness improves as the new fat cells grow into the existing buttock tissues.
What can I do after buttocks augmentation?
You may start walking immediately after surgery. A light compression garment is worn for six weeks post-operatively. Avoiding any position that applies pressure on the grafted area is important in the first couple of weeks. Sitting on the grafted areas may start very briefly at two weeks. There is a greater number of viable fat cells when long periods of sitting are delayed until 4 to 6 weeks after surgery. By waiting a few weeks to start sitting, the new fat cells have more opportunity to establish connection with the pre-existing blood circulation system. Thus nutrition is provided to the new fat cells.
What are the risks with buttocks augmentation?
The risks with this surgery are increased with pre-existing medical conditions such as asthma, diabetes, and high blood pressure. These risks need to be controlled medically and even then may preclude surgery. Risks associated with buttocks augmentation include but are not limited to the following problems.
How much will a buttock augmentation cost?
There is a wide range of prices depending on what exactly you are having done. At the initial consult we will give you our prices which include:
- facility or hospital
Other fees may include:
- lab work
- prescription medications
- transportation and accommodation, if you are from out of town
- personal nurse in the first 24 to 48 hours, if needed.
Dr. Hobbs wishes to provide you with the most natural buttocks augmentation using the natural materials already in your body.
