Buttock implants placed within the muscle should be measured to fit your anatomic constraints. I place both round and oval implants in an intramuscular position with a preference for round implants if possible to improve projection, improve roundness and fullness laterally, and prevent rotational deformities associated with oval implants. Oval implants may be more useful in some anatomic conformations. You would need to be examined in person to determine if round or oval would be best for your anatomy. Studies have demonstrated that sizes above 350 cc have a greater rate of complications, but most women choose an implant volume in the 350cc to 400cc range. The complications for buttock implants include need for removal, infection, extrusion, fluid collection, implant migration, implant visibility, and capsular contracture among others. There is no question that the BBL has fewer complications across the board than does the buttock implant. PS do not inject fat into the muscle to all but eliminate the risk for fat embolus and death. I perform both procedures, but I try to reserve the buttock implants for patients who truly do not have enough fat for the BBL. Sometimes I place implants in patients who want more volume after the BBL. I perform so many butt implant surgeries and BBL surgeries that I am not interested in trying to convince the patient that one surgery is bad and one surgery is good as so many surgeons attempt to do. I will provide recommendations, but, in the end, it is the patient's decision on whether to pursue a BBL or butt implant surgery with solid silicone implant
