ABSTRACT
Background: In recent years, the aesthetic market has become more prominent for being not only a tool to correct unwanted features but also a social means for improving quality of life. The use of 30% polymethylmethacrylate (PMMA) as a gluteal filler has grown in popularity all over the world, being sought after by men and women for body remodeling because it provides a natural look as well as significant long-lasting results. Methods: A retrospective, multicenter study analyzed the medical records of 2801 patients who underwent a total of 4725 gluteal filler procedures between January 2009 and December 2021 at the different locations of Clínica Leger. The study protocol was approved by the Brazilian National Research Ethics Commission. Results: The medical records of 2801 patients (2666 women and 135 men) who underwent 4725 gluteal filler injections were retrospectively analyzed. A total of 922,776 mL of PMMA was used (average = 329 mL/patient). The occurrence of 101 adverse events (2.1%) was observed, and no statistically significant relationship between the mean injected volume and the incidence of complications could be found. Conclusions: According to the data presented in this study, the use of PMMA injections with the appropriate volumes for aesthetic treatments and corrections is safe and effective.
