The deformity on your buttocks is difficult to treat. It will require exercising the scar tissue. It cannot be corrected by simply adding volume with procedures like fat grafting or fillers. it requires removing the scar tissue and that’s pulling on the skin first and foremost. These are complex procedures that may give some improvement but are unlikely to restore your bottom to normal.To get a better understanding I suggest having a few in person consultations with board-certified plastic surgeons. Anybody who comes up with a simplistic treatment plan like simply injecting fillers or fat is likely to leave you with disappointment.Best,Mats Hagstrom MD
