Congratulations on your BBL, Jaybee. I am sorry to hear that you are not happy with your results. Three months is still early to fully evaluate your results, and there may be quite a bit of change yet to come as the swelling resolves, the fat grafts stabilize, and the skin remodels or relaxes. It is not expected that your smaller side will enlarge, but the larger size may decrease. Depending on why there is a flat spot, there is a possibility that the skin will relax some and allow a more convex shape to develop. However, if this skin was pretty tight to begin with, there were tight bands, or you had significant concavities in this area, you will likely require additional treatments in order to obtain a final full, convex/round appearance. A review of your pre-op photos would be helpful -- if your buttock on the left was narrower, shorter, and/or had appreciable reduced volume compared to the right pre-operatively, there may be limits to what can be achieved, even with a revision. Your surgeon would be in the best position to make this determination. Generally, it is advisable to wait at least six months, and even up to one year, before considering a revision or additional surgery. Best of luck, and i hope you are realize the results you were hoping for. Dr. Ghafoori
