Can fat equalization be performed to revise a previous BBL and achieve better symmetry & same shape butt cheeks? (Photo)

I had a bbl 6/6/17. My 2nd day post op I noticed an undesirable shape and right side was larger than the left. I brought it to the attention of the surgeon immediately. As usual was told to give it time and that my skin was "tight". I am now almost 4mo po, it has improved some but my cheeks are 2 different shapes & size. The surgeon has agreed to do a fat equalization stating that it will smooth and reshape my cheeks. I've never heard of this produce used in conjunction with a bbl...thank you
