Speaking for myself, I would not go back to a surgeon for more surgery if they didn't do a good job the first time. There's no reason to have any faith in them if they did an inadequate job the first time around.
I would find someone else; someone with LOTS of gyne surgery experience. According to the doctors here, many times, revision surgery for gynecomastia presents even more of a challenge. So I would want someone I have faith in doing my second surgery, and certainly not the guy that took my money and left me with results I'm not happy with.
