How do I know if my nipple was completely cut and reattached? (Photo)

I had a breadt reduction last April from a G to a D. I'm happy with the results, I'm just wondering if my surgeon cut my entire nipples off and reattached as I thought that was fairly uncommon. I have cut/scars around both nipples and they look completely different than they did before the surgery. Can you tell from the pictures if that's what he did? I did have mild inverted nipples before, one is better and one is worse. Thanks.
