There are two ways a gluteal augmentation can be performed: the first one is to use bidimensional implants which, in my experience, are the ones that offer the most natural results. The other alternative is the fat injection –lipoinjection or lipofilling– which is performed along with a complete liposculpture.
The type of procedure is decided together with the patient. If the amount of fat of the patient allows it, the best option is to do a Lipoinjection. Otherwise, the only option would be to use implants. Due to my experience and commitment to quality and naturality of the surgery, I do not use round implants on the gluteus because I consider the results do not look natural enough.
