Hi. I have recently had an MRI scan due to hearing loss and been told by ENT consultant that I have an Acoustic Neuroma of 1cm. He has referred my details to another consultant (one week ago) and I am waiting to hear further. I live on the coast in North Wales so am unsure of where I will be referred to! I don't know whether 1cm is small or large! I am quite surprised to find myself feeling quite worried about what will happen (I'm not usually a worrier). I suppose what worries me most is the possibility of facial nerve damage if I have to have surgery. Is Gamma knife safer in this respect?
