Liposuction of outer thighs gone wrong, can it be corrected? (photos)

I had lipo done on outer thighs 8 months ago. I wanted a bit less "pear-ish" look but still feminine. I soon noticed that too much fat was removed from the upper part of the hips and on the buttocks. Now I look really sunken there! The surgeon says he will try to inject fat to fix this but I'm worried. He says it will be enough with 50 cc of fat, which I don't think is enough at all! Do you think my result can be corrected so that my hips and behind looks good again? / Thank you
