Hi, Star. I had a failed gamma knife and later had translab surgery when my AN was obviously growing again. After surgery, I did lose my hearing on the right because they cut the nerve with translab, but I had very little left by the time I had the surgery so it wasn't all that much different post surgery (although I have since gotten a BAHA and love it!). They were able to preserve my facial nerve which was really unexpected. I had been having facial spasms before the surgery, so we knew the nerve was involved. They did leave a tiny, tiny bit of tumor on the facial nerve in trying to save it. I'm not due for a recheck MRI until early 2012, but I assume all is well. My recovery went well, no worse than anyone else having surgery.
My neurosurgeon did tell me in advance that it is a more difficult surgery if you have had the GK because of the stickiness, but in my case the surgery was shorter than they expected--6 hrs instead of 8--and I had an excellent result. Everyone's AN is different, but I just want to encourage you that it's possible Allan can still have a good result. Best wishes to you both!
