Gamma knife vs Surgery for small AN
« on: August 29, 2014, 10:47:26 pm »
Hello all,

I have a recent diagnosis of AN after having symptoms of hearing loss and tinnitus. I am 26 years old and have no other current significant medical problems. My AN is 8 x 8 x 9 mm in size. I am trying to decide between surgery and gamma knife. I currently have fully functional hearing level with only a mild degree of loss. I'd like to hear any opinions/experiences between the two regarding the size of my AN and the related risks between each treatment options?

Also if there are any good websites/articles I can read that were helpful about AN?

We can only give you our own experiences.

In my case my AN hearing was about 90% gone when I was diagnosed with a 3mm x 4mm x 9mm AN. Six months later the AN had grown about 20% and the hearing on that side was 100% gone.

There are surgical techniques that might preserve hearing and Gamma Knife has also been shown to preserve hearing in some cases.

Here is some material I've gathered.

Google "acoustic neuroma hearing preservation" or some such and you'll probably find additional resources.

I suggest, however, that time is not your friend if you want to preserve your hearing.
3/15/18 12mm x 6mm x5mm
9/21/16 12mm x 7mm x 5mm
3/23/15 12mm x 5.5mm x 4mm
3/13/14 12mm x 6mm x 4mm
8/1/13 14mm x 5mm x 4mm (Expected)
1/22/13 12mm x 3mm (Gamma Knife)
10/10/12 11mm x 4mm x 5mm
4/4/12 9mm x 4mm x 3mm (Diagnosis)
