Buttock augmentation is the procedure used to give volume, shape and support to a certain region. The definitive procedure is made with PMMA, a substance approved by FDA and by the Brazilian Sanitary Surveillance Agency.

Problems like trochanteric depression, lack of side volume, flattened, disproportion with the rest of the body and small size, can be reduced with buttock augmentation. The treatment is simple and does not require a downtime. The buttock augmentation can also define gluteus.

The application of polymethylmethacrylate (PMMA) is made by microcannulas, blunt-tip needles extremely thin and long. In buttock augmentation, there is an insertion of microcannulas into the skin with a regular needle, which helps accuracy of the filling process and also working as a bruising precaution. There is no need for stitches when microcannula is used in buttock augmentation.

The blunt-tip microcannula, with its flexibility, can slide under the skin with lower risks of blow veins or nerves. Its narrow thickness and long length enables reaching any area, and evenly distributing the filler substance in buttock augmentation.

The implant has local anesthesia, under outpatient basis and none sleeping. During a buttock augmentation is possible to follow the process, opining about the application. The only recommendation for postoperative is to keep (the surgery region) away from any physical effort for at least a week. Exercise for the gluteus requires medical authorization.

The PMMA for buttock augmentation has good tolerance among women and men, being ahead of liposculpture and of the sore silicone implants, which requires hospitalization. While a small silicone prosthesis has 300ml and fixed form, the PMMA is a liquid implant with microspheres that are shaped according to the objective of buttock augmentation. Moreover, on the liposuction, the injected fat is resorbable, while PMMA is definitive.

Treatments against cellulite can be combined with buttock augmentation. Caused by the accumulation of fibrosis, in its most severe stage, cellulite can cause lumps and pain. The indicated treatment in these cases is a subcision. A clearing technique that reduces the fibrosis under the skin, softening the imperfections of the region. Once done, buttock augmentation helps in the restoration of the gluteus shape.

The so-called trochanteric depression, the lack of volume on the lateral of the hip, can be reduced with PMMA buttock augmentation. The rigid silicone implant does not provide improvement in this respect, as a liquid moldable substance applied with flexible microcannulas does.


All these benefits made the procedure well known as “the plastic surgery without cuts”. Its natural effect without hospitalization requirements or downtime, makes buttock augmentation a worldwide attempted procedure.

The Leger Clinic is an ISO 9001:2008 certified company for medical and aesthetic assistance for facial and body filler, including laser procedures. In addition, as a member of the Association of Health Tourism (ABRATUS), Leger Clinic has a specialized structure for foreign patients.


Recently a survey of the International Society of Aesthetic Plastic Surgery found out that the resorbable fillers are the second most frequently nonsurgical procedure performed in the country, seconded only to botulinum toxin, known by the brand name “Botox”. According to Dr. Roberto Chacur this is due to similar results of a surgery, without its complications. “Fillers are very popular for being a minimally invasive procedure performed in the clinic,” explains Chacur. The PMMA filler is as good as the resorbable and more indicated to buttock augmentation. In other places were, the hair laser removal, the non-invasive facial rejuvenation and, in fifth, chemical peel, CO2 resurfacing and dermabrasion.


In May, 2019, the Leger Research Group published a 10 year follow-up with more than 1.500 patients that had been through nearly 3.000 procedures of gluteal augmentation with PMMA. The case report on the Plastic and Reconstructive Surgery show a side effects rate of just 1,88%. The number is lower than other traditional procedures for gluteal augmentation like silicone implants and liposculpture that had complications on 30% and 10,5% of the cases. Each patient received and average of 321 ml of PMMA, which demonstrate that larger volumes of the product has no relation with side effects. Another breakthrough made by this research is that until now there weren’t any studies about the effects of PMMA in long-term, which helped the belief that the product could cause severe health complications after larger amounts of time, what was proved to be untrue.
