Brazilian Butt Lift: Buttock Fat Injection
There has been much talk about the Brazilain Butt lift.
It is different from a traditional butt lift in which skin is removed from the lower back and the sagging buttock skin is lifted.
It is different from Buttock Augmentation which is typically performed with implants that are most commonly fabricated of silicone
In my opinion, it is best to perform this procedure under general anesthesia due to the extensive nature of the injections and the need to inject deep into the buttocks muscle.
Subcutaneous augmentation can be performed utilizing several different techniques and in the case of lipoinjection (fat injection) it may require multiple staged procedures.
The fat is aspirated from the abdomen, hips, flanks or thighs using a syringe or suction collection technique. The fat is then transferred to smaller syringes, usually after a process of purification, where it is injected into the desired areas.
The results are difficult to predict because "fat take" (the amount of fat which survives after being transferred) can vary anywhere from 20 to 80%. The success depends on several factors. It is like trying to predict how many seeds will sprout when you plant them in the ground.
Fat must be obtained from a donor site and therefore satisfactory quantity and quality of fat must be available. The procedure requires an anesthestic and may be performed in the office or surgicenter. On average, 50% of the injected fat will be absorbed but the fat which remains is permanent. Several operative sessions may be required to achieve the desired result.
Risks can occur regardless of surgeon or technique. These include but are not limited to: infection, hematoma, discomfort, asymmetry, undesirable effect on an associated muscles, overcorrection, under correction, pain, prolonged swelling, dimpling, fat necrosis, fibrosis, abscess formation, adverse medication reaction, allergic reaction, need for additional "touch up" injections, palpability, visibility, distortion with muscular contraction, need for secondary revisions, and inability to guarantee a specific cosmetic result.
