Smart Lipo or Brazilian Butt Lift for Banana Rolls?

Treating the "banana roll" is not as simple as it seems. I think the banana roll is not a distinct accumulation of fat or a fat pocket. Rather I think it is a folding of skin caused from the weight of the buttock and somewhat loose skin.
This is the reason why I tend to see the banana roll in older patients, who have looser skin, and younger patients who have had liposuction of the upper lateral and inner thighs.
The solution depends on whether you want just a reduction of the banana roll or an overall enhancement of the buttock area.
If you want just a reduction of the banana roll, a very fine cannula liposuction at a superficial level will help. Taking out too much fat will eliminate support for the weight of the buttock and cause the skin to buckle and fold again.
If you want an enhancement of the buttock area in general, a fat injection to the lateral area of the upper thigh and buttock will act as a column of "support" for the buttock and give you a perkier buttock and obliteration of the banana roll.

Reducing your banana rolls, posterior upper thigh excess fat, if done properly and conservatively should give you improvement without making your buttocks drop.

Hi there-
The details of where to suction and how much, as well as where you would benefit from fat grafting and how much will depend on your exam and your goals. I'm not sure I would be helping you by giving you an opinion of what to do without having an understanding of where you're starting from and where you want to get to.
I would recommend that you find a Board Certified Plastic Surgeon with a lot of experience in BBL surgery and visit with them for a consultation. Most likely the correct option for you will involve a little of both liposuction (and the machine used is NOT as important as the person doing it) and fat grafting.
