GLUTEAL HARMONIZATION WITH POLYMETHYL METHACRYLATE (PMMA): ANATOMICAL FOUNDATIONS, INDICATIONS, TECHNIQUE, AND MANAGEMENT OF COMPLICATIONS

Abstract

Buttock augmentation with polymethyl methacrylate (PMMA) is a minimally invasive alternative for volumetric augmentation and body contour correction. Despite its widespread use in Brazil, the permanent nature of the material and the potential for late complications require rigorous technical standards and careful patient selection. This article reviews the anatomical fundamentals of the gluteal region, the properties of PMMA, indication and contraindication criteria, application technique, immediate and late complications, and management strategies based on the literature. Current evidence demonstrates that the safety of the procedure fundamentally depends on the technique, the correct anatomical plane, and volumetric moderation.
