Brazilian Butt Lift has been one of the hottest topics in plastic surgery for years. There have also been concerns about the safety of fat injections to the buttock. Ultrasound use in the butt augmentation has become a hot topic as we can now directly visualize the placement of the fat during a BBL. This not only enhances the safety of the fat transfer, we also believe this will increase the overall aesthetic result for patients as we can stay away from the muscle, but fill the different layers of fat in the buttock. This will allow plastic surgeons to increase the projection and fill hip dips safely under direct visualization with the use of the ultrasound!
