Just last week I had the ear lobe on the radiated side sewn up because a pierced earring had caused the hole to greatly enlarge. The doc who sewed it was the ENT who did the mega surgery 4 years ago, and he said he sees a lot of change in radiated tissue. Tried to get him to order HBO for healing, at my friend's HBO clinic in Mexico, but he said that probably wasn't necessary. Darn!
Minnie, I think the loosend skin around your mouth and mine is because we were without teeth for a time and there was no support. I just smile a lot which stretches it out, and is a good general practice anyway (grin).
