I highly recommend Middle Fossa with Dr. Schwartz! He is a genius! He (along with Dr. Friedman) preserved my hearing, and I didn't have a single balance or facial issue!
Dr. Schwartz recommended I do an ABR, VNG test and a closer MRI the day before my surgery. Based on those results they decided I was a candidate for Middle Fossa (instead of Retro Sigmoid). That made me feel confident that they wanted to make sure they knew exactly where my tumor was, and what it had affected before selecting a surgery approach.
Obviously, my results aren't typical (Dr. Schwartz even walked out of my post-op appointment saying that very line), but it can happen!
