Sorry, I can't help you with Gamma or Cyber Knife but there are many others on this website who can. Ann
Hi Carmen (and Ann
)
From a radiation/radio-surgery standpoint (esp. where your AN is deemed as "mid-size), there is a higher % of hearing retention. As with any AN procedure (surgical or radiation), there is the risk of hearing loss in the AN ear but for radio-surgery, the % run higher for retention.
For me, my hearing is still 100% of what it was at the time of my Cyberknife treatment 1 year ago (at the time of treatment, it was on the bottom of the "normal" range, with voice recognition at 96%).
In checking with the dr's that volunteer their time on the Cyberknife Patient Support board, they also note higher hearing retention. Some, immediately post-radiosurgery, do note a diminish level of hearing approx 6mos-12mos post treatment due to tumor swelling (with radiosurgery, it will swell for a time, then shrink a little) in which the hearing with decrease a bit... and many (such as myself) do report that post-swelling, hearing goes back to what it was at the time of treatment.
Hoping others chime in as well.... I can only share from my personal experience.
