Objectives: Participants will understand essential safety principles in autologous gluteal fat grafting, including anatomy-based planning, subcutaneous-only injection, and ultrasound-guided technique. They will learn optimized harvesting and grafting protocols, complication prevention, patient selection, and methods for achieving natural, predictable contouring while minimizing risks such as vascular injury and fat embolism. Introduction: Introduction Brazilian Butt Lift (BBL) has become one of the most sought-after body contouring procedures, but its rapid growth has been accompanied by significant safety concerns. Advances in technique, anatomical knowledge, and fat grafting protocols have been key to reducing complications and improving outcomes. This presentation outlines a comprehensive, safety-driven approach to autologous fat grafting for gluteal enhancement based on refined technique and long-term clinical experience. Materials / method: A retrospective analysis was conducted on patients undergoing autologous gluteal fat grafting using exclusively subcutaneous injection techniques. Fat was harvested via low-pressure liposuction, purified through mechanical processing, and reinjected with controlled cannula placement and directional flow. Safety parameters included cannula type, injection plane, ultrasound guidance, fat volume thresholds, and perioperative management. Results: Across the reviewed cases, the standardized safety protocol resulted in natural contour enhancement with no incidences of pulmonary fat embolism, deep intramuscular injection, or major vascular complications. Complication rates remained low, limited primarily to minor asymmetries and transient swelling. Patient satisfaction was consistently high, correlating strongly with adherence to subcutaneous-only graft placement and strict intraoperative monitoring techniques. Conclusion: Autologous fat grafting for BBL can be performed safely when grounded in a meticulous understanding of gluteal anatomy, disciplined technique, and adherence to evidence-based safety protocols. A structured approach—prioritizing subcutaneous placement, controlled fat delivery, and real-time monitoring—ensures predictable aesthetic outcomes while minimizing risk. This methodology reinforces that artistry in body contouring must always be anchored in patient safety.
