Buttock Enhancement Through Combination Liposuction And Fat Injections

Enhancement of the buttocks has become enormously popular over the past decade. Most methods of cosmetic buttock surgery are perceived as that of increasing its size through either implants or, more commonlytoday, fat injections. But buttock enhancement is as much about contouring and reshaping as it is about size increase alone. Large poorly-shaped buttocks are far less appealing than slightly smaller ones that have a more desireable shape.

When evaluating the buttocks, it is best to see it as an anatomic structure with different areas as zones that can be modified. There are essentially six aesthetic zones to the buttocks which can be described as follows: zone 1 is the midline lower back/sacral area, zone 2 is the upper lateral region or low flanks often also called the muffin tops, zone 3 is the middle lateral region where the muscle inserts, zone 4 is the low lateral or greater trochanter area, zone 5 is the upper inner thighs, and zone 6 is the amount of buttock projection seen in the side view.

The relevance of these buttock zones is that they all represent areas of either reduction (liposuction) or augmentation. (fat injections) Zones 1 and 2 are the areas of greatest liposuction fat removal while zones 3, 4 and 6 are the primary areas of fat injection augmentation.

Improving buttock shape is more than just injecting a lot of fat all over the entire buttocks. Skillful reshaping by fat removal combined with fat augmentation is a more successful approach. In many patients, it just isn’t possible to place enough fat or have enough of it consistently survive to create a better shape by simple volume addition alone.

In improving the shape of the buttocks the contour of the hips is a key area. Buttock projection can look diminished when the hip and back area has a good thickness of fat. This obscures any appearance of an upper gluteal shelf. When liposuction is done to reduce the hip and back fat, an inward skin retraction occurs. This creates an inward indentation or concavity which can match the curve of the lower of the lower buttocks as it dips inward towards the posterior thigh. By so doing, the illusion of a greatee central buttock projection is created. This can be further enhanced by concurrent fat injections into this central mound. This is a good example of the ‘ying and tang’ approach to increasing any body contour. The combination is always better than either approach alone.

The survival of fat injections in the buttocks is always an issue of concern. While there are numerous methods of processing fat prior to injection, none have been shown to be better than another. Some method of concentration is important to eliminate excess oils and fluids. In the buttocks, unlike many other face and body areas where fat is injected, there is a choice of injecting into the subcutaneous fat layer, the muscle, or both. The buttocks have a large gluteus maximus muscle and most of the fat injected should be into it. This will ensure the most amount of injected fat survival due to the better intramuscular blood supply.

Buttock augmentation is best done through a combination of zonal liposuction reduction and intramuscular fat injections. This is best for those patients that have an excess of fat around the buttocks in the hips, back and waistline.
