What is this paper about

Buttock augmentation safety is not defined by aesthetics alone: this evidence map shows that risk concentrates around where material is placed and what material is used, with subcutaneous image-guided fat grafting looking far safer than intramuscular injection or illicit permanent fillers. The full read separates low-complication fat-grafting and implant techniques from the dangerous edge cases — fat embolism, silicone embolism, septic shock, granulomatous hypercalcemia, sciatic nerve injury, and difficult filler migration — giving clinicians and patients a practical map of where buttock augmentation becomes unsafe.

Abstract: To synthesize current clinical evidence regarding the complications associated with various buttock augmentation techniques, including autologous fat grafting, silicone implants, and synthetic fillers. The review uses 54 references and builds its evidence map from 54 original studies with 3,810 total participants/sample observations (topic-deduplicated ΣN). This scoping review suggests that the safety of buttock augmentation is dominated by two modifiable factors: the injection plane and the material used. Autologous fat grafting confined to the subcutaneous plane, particularly under ultrasound or Doppler guidance, was consistently associated with low complication rates, whereas intramuscular fat injection carried a reported 16-fold higher mortality risk and illicit or non-absorbable fillers were linked to severe systemic events including silicone embolism, septic shock, and granulomatous hypercalcemia. Implant-based and composite approaches remained feasible but retained recurrent risks of seroma, malposition, flipping, neuropraxia, and wound-related complications, with one 423-patient dual-plane composite implant-plus-fat series reporting a 10.8% implant-related complication rate and seroma as the most frequent issue. These signals support prioritizing image-guided subcutaneous techniques and heightened vigilance for late-onset filler and medical-tourism complications. Future prospective comparative studies with standardized complication definitions and longer follow-up are needed to clarify the long-term safety of composite and image-guided approaches.
