Lyn ~
Add me to the list of those AN patients who underwent the retrosigmoid approach surgery. Like Adrienne's doctor, my neurosurgeon said basically the same thing: "My AN patients don't get headaches"...and I didn't - ever. I have the titanium plate/screws instead of body fat - and never had a problem, except that it took close to a year to regain full sensation on the 'AN side' of my skull, but it did return. My brainstem was moved ("just a little" - according to my surgeon) but I suffered no ill effects, i.e. headaches. My hearing in the affected ear was essentially gone by the time my AN was discovered so I had no illusions about getting it back. Good thing, too, because I didn't get it back. Otherwise, I had a very successful AN debulking surgery with minimal complications. That is simply anecdotal evidence and based on my being fortunate enough to have a highly experienced neurosurgeon (thousands of AN removal surgeries) but I think it bodes well for you, Lyn.
Bren ~ Good information, very comprehensive. Thanks for the link.
