RESUMO
Objective: The robust safety and efficacy profile associated with the use of biodegradable fillers such as poly-L-lactic acid (PLLA) for facial rejuvenation has resulted in a growing interest in off-label use for various aesthetic applications, including gluteal augmentation. The authors describe a novel targeted and individualized technique of PLLA injection into the buttock region. Methods: The technique involves clinical and anatomical evaluations of the gluteal region, and there are three distinct approaches for injecting PLLA in the gluteal region based on the most important factor to be improved: (1) skin quality, (2) contour and lifting, or (3) projection and volume. Results: This novel technique is associated with favorable patient outcomes in terms of improvements across all key areas of gluteal augmentation; improvement in skin quality and laxity, contour improvement and lifting, and gluteal volume and projection. Since its initiation, this technique has been found to be both cost-effective and clinically efficacious, with demonstratable benefits achieved with a lower volume of PLLA compared to other PLLA injection techniques. Limitations: Assessment of patient outcomes with this technique have, to date, been subjective clinical observations, which does not include quantitative outcomes such as patient satisfaction data or safety outcomes. Conclusion: We describe an optimized and individualized approach for injecting the collagen biostimulator PLLA in the gluteal region according to the needs of each patient.
