debgit,
In terms of radiosurgery being an option, certainly size is not a consideration at 1.2 cm which is well below the generally accepted ceiling of 3 cm.
Of the symptoms you list, nothing in particular jumps out as me as something that would prohibit pursuing that option either. Radiosurgery will not solve symptoms that are associated with the physical presence of the AN on a critical structure, typically the cerebellum. At 1.2 cm I would be very surprised if your AN is having that level of physical impact but certainly the MRI would show the doctor what is involved.
Specifically to the symptoms you list
Hearing - What's lost is lost as a result of the damage to the "hairs" on the nerve and the objective of the treatment is to preserve what's left. Radiosurgery typically is a little better here but it doesn't sound like you have much "usable" hearing left
Tinnitus ( white Noise) - this is a reaction of the brain to the damaged nerve. Removing the AN surgically or treating with radiosurgery in all likelihood won't create a significant change in the end.
Balance - This needs to be assessed by a neurosurgeon to determine if the physical location of the AN is the issue, if so, then surgery might be a better option. However, my guess is that this is associated with small shifts in pressure and damage to the balance nerve as the AN is growing. Your body will adjust to this over time when the AN is stable ( dead or removed). I would also guess that dizziness is directly related to the balance / vertigo issue. When that resolves the dizzziness probably will too.
So, from my perspective, both options are equally viable for the symptoms you describe and you could go either way. The one consideration you did not mention because you aren't having any issues is the facial nerve function. Of the two options, I think the studies would show radiosurgery has less risk in this area than open surgery.
As far as staying in your backyard, you might want to consider Dr. Spunberg who runs the Cyberknife facility in West Palm Beach for a radiosurgery consult as you consider your options. He also responds to inquiries on the Cyberknife Patient support board at

Dr. Spunberg is a board certified radiation oncologist practicing in Palm Beach County, Florida for over twenty years. He is a fellow of both the American College of Radiology and the American College of Radiation Oncologist. He graduated from Harvard Medical School and completed his residency training in radiation oncology at Columbia-Presbyterian Medical Center in New York. Particular interests include the use of Cyberknife in prostate and lung cancer, as well as intracranial and spinal tumors. He is especially excited about combining treatment with the Cyberknife with other therapeutic options such as IMRT and chemotherapy.
Hope that is helpful,
