I don't know if there are rules here about linking to other forums so I won't post a direct link, but in addition to my own experience, there was a recent series of posts by a girl on ->-bleeped-<- who had a great outcome and eventually included some photos of how her scar was healing. I was already convinced that Thomas knows what he's doing, but reading her story helped assuage any remaining doubts and gave me an idea of what to expect. If you Google "3.5 weeks Dr. Thomas femlar ->-bleeped-<-" it should get you started. She didn't have any of the prior complications that I was dealing with, so it might be a better example for you.
That being said, having been operated on by both Dr. Thomas and Dr. Kim, I think they are both excellent surgeons and both capable of providing good results. The added bonus of a trach shave and voice modification in one go is certainly an advantage worth considering, however.
