I'm glad you found someone with an acceptable solution for you. However, I would advise against any delay if you're concerned about your hearing and you already know that you're going to have surgery. From my own experience, and from reading through this forum and others, it seems like no one is going to die overnight from an AN, but you may experience sudden loss of hearing or facial nerve issues while waiting. I had some facial paralysis last November, had my MRI in March and lost the last of my hearing about a week after. I had my surgery scheduled for June 13th, and experienced a worsening of the facial nerve issues two weeks prior to the op. I'm not saying to panic, but don't let anyone reschedule and delay because you're not an emergency, there may be no rush, but there's no sense in delaying longer the it takes for you to get your house in order and the doctors to find a slot on their schedule.
Good luck!
