Safety Considerations of Fat Grafting in Buttock Augmentation

Autologous fat grafting for buttock augmentation is one of the fastest growing plastic surgery procedures, but has also received significant publicity for the relatively high mortality rate secondary to fat emboli. The literature has grown exponentially in the past 5 years on this subject, helping to clarify our knowledge and providing recommendations to minimize risks, including avoiding intramuscular injections, placing the patient in the jackknife position, and utilizing larger-bore cannulas. Since the application of these recommendations, the rate of pulmonary fat embolism has decreased from 0.097% to 0.04%, with a current mortality of 1 in 14,921, making it statistically safer than abdominoplasty. Despite the evolution in our knowledge, techniques, and outcomes, it remains of utmost importance to properly select and educate patients about the safety of fat grafting for buttock augmentation.
