Abstract

Objectives: The primary objective was to assess the effectiveness and safety of polymethylmethacrylate filler injections at the muscle level for buttock augmentation. Introduction: This study presents a 17-year experience using long-lasting polymethylmethacrylate fillers for intramuscular buttock volume augmentation. With over 1.000,000 cc of product applied, we aimed to achieve natural, minimally invasive, and safe volumetric gains. A multicentric study conducted in Brazil (Sao Paulo, Rio de Janeiro, and Porto Alegre) examined the intramuscular approach for gluteal volumetry. Materials / method: The study included over .1.000,000 cc of long-lasting polymethylmethacrylate fillers, applied intramuscularly, to support and enhance gluteal volume. Results: The results were considered highly satisfactory and natural by both the medical team and the patients. The volumetric gains achieved with this intramuscular approach were significant, and the product remained within the muscle, providing support without adding weight to the skin. Adverse effects were minimal in comparison to established techniques such as liposuction and silicone prosthesis. Conclusion: In conclusion, this study demonstrates that intramuscular polymethylmethacrylate filler injections provide a natural, safe, and promising method for buttock volume enhancement. The technique offers excellent results with minimal adverse effects, making it a valuable alternative to conventional procedures like liposuction and silicone prosthesis in the quest for gluteal volumetric improvement.
