I, too, was kind of at the mercy of what approach my surgeon wanted to use. At first, he told me translab and then after conferring with the doctor that would be operating on the tumor (that part of the surgery) they switched to retrosigmoid because it gave them the best view of my particular tumor (it didn't have anything to do with hearing as in other cases).
Personally, I would get another opinion. From my experience, surgeon's will generally favor the approach that they are most comfortable with. Some will give the option of approach over to the patient because they favor neither one.
If there was a higher risk of facial nerve damage with that approach, I wasn't aware of it. My main goal was to get the ENTIRE tumor removed. My surgeons could have used whatever approach was necessary to achieve that goal in my mind. Luckily, I spoke to a very good surgeon with lots of experience. Read my blog (address listed in my signature below) for more insight into my whole journey if you feel inclined.
A choice of surgeon and approach are personal ones, to me. Everyone has different goals of surgery. I just happened to have a more basic need of getting the entire thing. As Jenni said in consultation with our surgeon, she just wanted to be sure that when she was old, she would have to buy *2* rocking chairs instead of 1. The rest we'd deal with as it came.
Good luck in this part of the journey. Let us know how else we can help.
