What does buttock augmentation surgery consist of?

A) Microfat grafting: By means of a cannula that is thinner than the ones used for conventional liposculpture, the surgeon removes the fat from certain areas of the body, such as the lower back, abdomen, waist and hips. He then purifies the fat collected and injects it on the buttocks drop by drop, very close to blood vessels to be sure that the injected fat will have adequate blood supply.

B) Silicone implants: The surgeon makes a small incision of 2 or 3 inches (5 cm or 7 cm) between the buttocks, right inside the midline. Through this incision, he makes a pocket inside each buttock and places the cohesive silicone gel implants inside each one of them. There are two possible locations for the implants, the location will be decided according to each patient's needs.

Submuscular: If you need to enhance the upper part of the buttocks and the lower part has a good volume (this is what most frequently happens), the implants will be located beneath the buttock muscle (gluteus maximus), approximately where jeans pockets would be.
Subfascial: If you need to enhance the lower part of the buttocks and the upper part has a good volume, the implants will be located between the buttock muscle and its fascia (fascia or aponeurosis is the tissue that covers the muscle).
