Thought that I would post an update...Things ARE getting better.
Harry had a bout of aspiration pneumonia last week, but that was quickly controlled. Picc line was taken out last week and two antibiotics are now taken orally. (Well, not exactly orally, but via peg tube.) Hyperbaric treatments are proceeding and the multiplace chamber is much more comfortable and less intimidating than the monoplace chamber used last year.
The best news is that the hole in Harry's mouth is 2/3 closed and the oral surgeon expects that it will fully close soon. Oral antibiotics will be discontinued in another two weeks and then we will cross our fingers and hope that no infection flares up. Still no eating until the end of March at the earliest. Pain is getting better.
Things are looking up! He may avoid more surgery after all!
