tisha,
I'm going to try my best at this... bear with me.
As you note, all treatment options (regardless if microsurgical or radio) have risks... hearing loss being one of them (for all AN treatments). This, unfortunately, is a reality of our AN journey. Now, we know, as it pertains to radio, that with fractionation, it helps to provide a higher success rate in hearing retention. In my case, with 5 day/dose fractionated CK, my team save 100% of my serviceable hearing (I am at 92% in my AN ear). I know of those that had 1 day/dose (GK) that went into radio treatment with very low serviceable hearing in their AN ear and did lose the remaining. I know of those that had fractionated CK and still had hearing loss (not completed by diminished).
to try to help the cause here.... if you sit back...and look at what is going to give you the best odds in saving your hearing, if that is your ultimate goal in your AN treatment... then go with your gut as to what will best help achieve your goal. For me.... hearing preservation was my ultimate goal. So was stunting the dang brain booger. For me and me alone, like you, I researched out all the radio options and took into consideration what would give me the best success rate in stunting the growth as well as saving my hearing.. and for me, I made my choice.
You are doing fantastic research...so, for you, for your ultimate goals in your AN treatment... for your situation (ie: location, finances, etc)... you will choose what will work best for you.
Gawd, I hope that came out well.
