Kevin ~
You certainly do have a dilemma. Because you asked for advice, I'll offer...Brian's. Actually he 'beat' me to what I would have answered: that Dr. Wiet should be consulted before you throw your plans out the window and opt for HEI and the ensuing financial chaos you indicated that move could cause.
You also have to consider that if you changed plans now, days away from your scheduled surgery, the Middle Fossa procedure was performed at HEI and your hearing was not preserved or other unwelcome complications arose, you would, no doubt, be extremely upset...with yourself, for being too easily swayed and not making a firm decision.
Nothing wrong with seeking the best possible outcome and no one will argue that preserving your good hearing in one ear isn't a reasonable priority. I just don't want you to make a rash move that you may ultimately regret. Unless you have some hitherto unmentioned reservation about Dr. Wiet and his plan for Translab surgery to remove your AN, I would suggest that you wait until Monday (22nd) and consult him as to why he is using the Traslab approach and that you're now conflicted. Once he explains the rationale for his decision to use the Translab surgical procedure he'll probably tell you that it's your call - and he'll be correct. At some point, you just have to take a calculated risk and choose a doctor, facility and procedure and then hope (and pray) for the best possible outcome. Ultimately, all AN patients do that, whether they choose surgery, radiation, both or just observation. It's a risk but one you absolutely must feel comfortable with taking or your ability to make a choice will be paralyzed - and that isn't an option.
We'll collectively support whatever decision you make so please let us know what you decide. Thanks.
Jim
