Dear Yolanda, Thanks for submitting your pictures and your goal picture. Fat injection to the butts, eventhough it sounds like a great idea, is a waste of time , money and dreams. This is based on many patients who came to my surgery center for butt implants surgery after the disappointment from the fat injection that was done by other surgeons. According to these patients, the fat disappeared completely or almost completely after 6 - 12 months. Think about it, if fat injection was consistent and reliable, breast implants would have disappeared from the market or their numbers would have been reduced dramatically. The reality is that last year, breasts augmentation with implants was the number one cosmetic surgery performed in the US... Your best option is butt implants. When done correctly, they look natural and very attractive. Based on your goal picture, you will need implants with a volume of, about 750cc. For your anatomy, oval round, ultra soft silicone implants , placed in the subfascial pocket, will give you the best result. Do your due diligence because not all results are the same and there are different techniques and different shape, size and texture of implants. Consult only with board certified plastic surgeons who do lots of butt implants surgery in accredited surgery center for your safety. Mos importantly, check the before and after pictures to make sure that they are numerous, consistent and attractive. Check also the ' realself' reviews for positive patients experience which provide important information on the surgeons. Best of luck, Dr Widder
