For those who asked me to post an update...
The surgery went wonderfully...better than expected. Dh can actually HEAR out of his right ear for the first time in years! But, because the procedure was a little different than the doctor expected, he wanted dh to stay overnight for observation to make sure he doesn't have any nausea or vertigo...common effects after this type of thing.
So, tomorrow, I'll be carting him home.
Thanks for all your good thoughts and prayers. I'm sure that without them, things wouldn't have gone this good!
