Buttock bioplasty is one of the alternative procedures that aims to correct glute irregularities, asymmetries and depressions. This technique is an option for people who have a non-uniformly shaped or disproportionate gluteus, such as trochanteric depression.
The procedure is performed in a doctor’s office, without surgery, without hospitalization, without cuts and returning to the same day activities, practicality that led to the indiscriminate use of the technique, whose main filler product is polymethyl methacrylate (PMMA). A definitive net implant, PMMA is legally marketed in Brazil by some companies that have authorization from Anvisa to produce it, however, some professionals, mostly non-medical, started to use banned products like PMMA and perform procedures in places without health surveillance license. The irregular use of medicine has caused doubts about the safety of polymethyl methacrylate, however, two recent studies indicate reduced risks in the use of the product, one of them even points to a smaller number of complications than what is verified in techniques such as liposculpture and gluteoplasty. One of them, released in 2016 during the 1st Brazilian Consensus Screening Symposium Symposium, was conducted with 36 physicians from all over Brazil and recorded only 719 complications out of 87,371 PMMA fillings, equivalent to 0.823% of the total. The second was a study by the Leger Research Group approved by the Research Ethics Committee (CAEE # 86722118.8.0000.5291) and published in June 2019 in the American Society of Plastic Surgery magazine Plastic and Reconstructive Surgery, which followed more than 1,500 patients. for 10 years totaling almost 3,000 procedures and indicated a risk of less than 2% in gluteus augmentation with PMMA.

One feature that can be resolved by gluteal filling is trochanteric depression (disproportion on the sides of the buttocks). The procedure can be done with polymethyl methacrylate (PMMA), hyaluronic acid or other biocompatible substances registered by ANVISA, giving the glutes the shape desired by the patient.
The gluteal bioplasty process is done after face-to-face medical evaluation. Its realization begins with a proper cleansing of the skin of the region. Afterwards, the patient should sit with the spine erect to make one of the markings on the support line. Each glute is numbered in its four quadrants, as marked on the mold.
Through a minimal hole, the microcannula is introduced. It has an atraumatic tip, which prevents injury to the vascular-nervous bundle. The procedure happens without bleeding and there is no need for dressings.
The liquid used to fill the buttocks has a variable amount, according to the indication of the attending physician, in the consultation in which the evaluation is made.
