Can Back Roll Fat Be Excised During Breast Lift Without Compromising Blood Supply to the Area

Yes it can but it depends on the extent and distribution of the fat as well as the condiiton of the overlying skin. I commonly perform this in combination with breast reduction.

Liposuction of the back roll would be a better option to maintain blood supply. It has the added benefit of no scar in the area and the possibility of skin tightening afterwards. Good luck
