Background:. Many techniques for buttocks augmentation have been developed and published, for a more natural, satisfactory, and safe result for the patient. It has been a challenge to find a technique that presented not only volume gain but also gluteal remodeling. Methods:. A total of 1,681 patients who underwent gluteal augmentation with Polymethyl methacrylate (PMMA) between 2009 and 2018 were selected for this retrospective cohort study. Data collected included demographics, procedures data, and postoperative outcomes. Side effects were calculated and compared using the Student’s t test. Results:. A total of 1,681 patients (1,583 women and 98 men) who underwent 2,770 gluteal fillings had their cases retrospectively analyzed. They were injected with 540,751.00 mL of PMMA injected. The patients’ mean age was 39 years, and the mean volume injected in each section was 237 mL during the first procedure and 147 mL during the second procedure. The authors observed 52 cases presenting side effects, representing a rate of 1.88% of 2,770 procedures carried out. The statistically significant (P = 0.02) presence of side effects was detected in relation to the total filling volume. Conclusions:. This study has demonstrated that gluteal augmentation with PMMA is one of the best options for this type of procedure. In addition, the findings suggest that the guidelines concerning gluteal augmentation must include PMMA filler as an option because PMMA proved to cause few side effects, as demonstrated by this patient cohort.
