Hi Yenna,
Welcome to the forum. Phyl has moved your post for you, she is a good mother hen that way.
My first reaction was about the tinnitus. It is a badge of honor for almost all ANers; most of us will have it the rest of our lives. Even if you had had the CT w/contrast or an MRI a year earlier, and caught the AN then, and saved some hearing, you would very likely have the tinnitus anyway.
I looked at the Shands web site. They are using a LINAC machine in single-shot mode, with a metal head ring. This makes it similar in effect to Gammaknife. You can find other facilities that use LINAC, Trilogy, or Novalis for a 4-5 week FSR treatment protocol.
Being a CK patient myself, I would suggest taking a look at the cyberknife support web site. There is a forum where you can post questions to practicing doctors, and a link where you can get contact information for some of the doctors. Dr. Spunberg, for instance, is at the Cyberknife Center of Palm Beach, FL.

http://www.cyberknifesupport.org/about_the_doctors.htmlCyberknife is done in 3 to 5 days, using a plastic mask to hold your head in place during a 30-60 minute treatment each day. It combines the high precision of the one day treatments with the gentler impact of fractionated treatments.
There are people on this forum who have used most of the available systems, so if you are looking for one in particular, someone may come along with a specific suggestion for you.
Best wishes on the outcome.
Steve
