Hi Wendy, I was diagnosed with a 1.7 cm acoustic neuroma and a .8 meningioma on Oct. 20th. After going to Mich. Ear Inst. and learning about the surgical approach I reached out for prayers and help with other options. I learned from a friend she had the gamma knife done on her 1.8 cm in Dec 2004 and has had excellent results. I had the gamma knife procedure on Nov. 23rd. and haven't noticed any substantial changes yet. I am 59 and felt the gamma knife was my best option. I have 45% hearing loss and didn't want the invasive surgery because I would have had 100% loss with it. My balance has been affected, but I didn't realize that was my problem. I thought it was due to severe allergies. I wish you well and will keep in touch with all of you. Ann
