I was operated on in November of 2004, and my AN is also growing back, it is approximately 4mm and my ENT indicated that even though it is 10 years, he thinks it is too soon for it to be growing back. I had a small AN (approx 8mm) but was told that my symptoms were very large for such a small tumor. It was removed using the subocciptal approach, and I lost hearing in my right ear, tinnitus got worse and my balance which the doctors thought would come back to at least 90%+ actually never did. So now they may want to use the Gammna knife, I was wondering if anyone can tell me if the knife was successful, and are there any side effects. I was told back in 2004 that there was not enough long term data to take the chance of using the Gamma knife, it was unclear at the time what the long term effects would be. I would like to thank you in advance for any help that you can give me.
Sincerely
