thanks all. I had a consult with Dr. Manghan and last week, and was very impressed. Two things that really stuck out vs. other surgeons I'd talk to:
1) he is on top of the research and literature. He knows what the latest studies have shown, he know what results local Seattle practitioners have had, and he's published his own seires (Laryngoscope 114:1455-1461, Aug 2004) with some really fantastic results
2) he really took the time to look my films over and discuss the data he used as the basis for estimating the likely outcome for me. He pointed out two things that other surgeons either didn't notice, or didn't feel the need to tell me. First was that, despite some of the contrast shots showing what looks like the tumor pressing on the brainstem, other shots clearly show CSF fluid barrier present between tumor and brainstem, which he says is a good sign. And second, he pointed out the advantage he'll have since the tumor does not fully occupy the inner ear canal -- there's 4 mm of clearance towards the end, which gives him a better chance to see where the nerves are.
after lots of research and discussion, I'm inclined to have Dr. Mangham do the surgery for me at the end of Nov.
