Hi, Bernadette...Mine was 12 years ago, so gravity has done its work! LOL Honestly, I didn't have all that much to begin with, but when they reduced/lifted the "good" side to match the TRAM, it actually looked like I had more than I started with. Like I said, it was PERKY!
The nice thing about the TRAM is that it loses weight with the rest of your body, so if you do lose some weight later, you won't be "mismatched."
I've had a lot of back problems that may be associated with the TRAM, but looks-wise, it's fine. I didn't have a good back to begin with, and messing with the support system was probably not the wisest choice for me. But hindsight is 20-20.
Again, hope all goes well with your surgery!
