Hello and welcome!
I landed in the same situation you are in, where once diagnosed, I was given the option of retrosigmoid or translabyrinthine surgery, radiation or wait and watch. It truly was a difficult decision to make. I spent one year researching all my options, speaking with several neurosurgeons and trying to decide which risks I could live with and which ones I couldn't. I have a history of not doing well with anesthetic so facing a 9 hour surgery truly worried me. At the end of my year of research, I realized a decision had to be made. My AN had grown from 1.8cm to 2.4cm. I chose single session Gamma Knife and had the treatment 6 months ago. I felt a great amount of relief once the decision was made and the treatment behind me.
I have some hearing loss, balance and occulomotor issues but nothing I cannot cope with. I continue to work full time and other than needing to pace myself and get lots of rest, I have no complaints. I just had my first 6 month post treatment MRI and will be posting the results in the next few weeks after I see my neurosurgeon.
Please send me a personal message with any questions if you would like more details of my experience. As others have said, do your research, speak to several specialists and choose one who has lots of experience dealing with our little Alien's! You want the best possible odds to be in your favor!
