RLM,
Welcome to this forum. As you have already discovered, it is a great place to get info and support.
Thought I'd throw this out there for you. My husband and I decided to go with an ENT surgeon in a somewhat rural area. But we sent his files off to a doctor that is a leader in the field at a CCC and had a phone conversation with him regarding the treatment plan. He was able to let us know that he agreed with the treatment plan (though he did suggest adding concurrent chemo, which the smaller center wasn't doing at the time) - he also knew of the ENT surgeon and calmed our fears by calling him "world-class."
Certainly this route is not as good as actually going in person for a second opinion, but it could be something to consider if you are feeling like you would like to have some confirmation that your chosen path is the best.
Wishing you all the best ,
Anita
