Mary -
As you say, a big decision is on the horizon. I'm glad you have your husband to support you; family is really important at a time like this.
I think eliminating the watch and wait option from your choices is a very wise decision in light of your decreasing hearing and your balance problems.
If it helps, I had retrosigmoid almost a year ago and SSD is pretty much my only side-effect. I had small problems after my surgery, but with time they went away.
I think it's a great idea to check into GK and CK before you decide what action to take; it's good to look at all the possibilities before you make your treatment decision.
Keep us posted,
Jan
PS - I'm glad to hear it was warm & sunny somewhere today. I was just outside about an hour ago and we had huge snowflakes coming down. Didn't look like they were sticking though - thank goodness!
