Just curious to see if things have righted themselves as I had the same prob and it has been three years post op and the "crater" is still there - about 1/2 x 1/2 deep - yuk. Other people I know have had it done and say that it shrunk back to normal. My luck as usual for things to go wrong down there.
The gyne said that it didn't heal very well but didn't recommend more surgery because of scar tissue so it looks like I have to live with it now. Not good with tampons, sex and tight clothes.
