Butt Implants with Fat Transfer to Hips and Thighs? Butt implants with fat transfer is the best of both worlds! It is an option and very common in my practice. It allows the augmentation of the implant and the shaping of the liposuction. The fat that is harvested can also be used to enhance the hips or other areas that your plastic surgeon may want to enhance after the placement of the implant. At times the implant can lack fullness laterally and in the hips. It can also add a buffer to the implant, softening the feel and appearance. Please discuss you butt augmentation with a board certified plastic surgeon that performs a high volume of these procedures.
