Hello Brymommy15, It’s a pleasure to answer your questions! Every patient is unique and plastic surgeons have different pre-operative protocols, customized for every patient to achieve the best results. Many of my full-figured patients who desire flat abs and a fuller, beautifully rounded backside opt for Vaser Liposuction with fat transfer to the buttocks (BBL) and Renuvion (J-Plasma) and get amazing results. Request an in-person or virtual consultation with a board-certified, experienced plastic surgeon to assess your candidacy for BBL with Renuvion based on your age, skin laxity, body shape, and health status, among other factors. During the initial consultation, he/she can help you decide if adding volume to your rear will be proportionately appropriate for your appearance and how much fat volume should be grafted. Have in mind that in states such as Florida and New York, the maximum liposuction aspirate that can be taken out are 4 and 5 Liters, respectively. When the lipoaspirate surpasses the 5 Liters, my patients get admitted overnight in the hospital. The maximum liposuction that one can be safely removed depends on the amount of lidocaine in the tumescent fluid (not more than 35mg/kg which is the gold standard of care) that can be infused to perform the procedure. Moreover, I also recommend my patients obtaining a medical clearance from their primary care physician (or cardiologist for age >45) prior to BBL procedure. Safety is of utmost importance when undergoing large volume liposuction. BMI over 30 is associated with higher risk of complications such as infection and wound dehiscence. However, this applies specifically to patients who are undergoing procedures that include large incisions such as an abdominoplasty and breast reduction. Best wishes! Dr. De La Cruz.
