Hi Jed,
I can only weigh in on two of your questions regarding doctors and hearing preservation. First, I do not know Drs. Pannullo or Greene. I did have a consultation with Dr. Kondziolka, and he was my first choice. He has an amazing track record, he was personable, had a great "bedside manner," he was responsive to all of my inquiries, and his reputation is quite solid. I think he has a little bit of the god-complex, but his confidence was also reassuring. The only reason I did not go with him was at the time of my decision, his practice had been impacted by Hurricane Sandy which made things more complicated--so I went to his former colleague Dr. Lunsford in Pittsburgh (who was a mentor to Dr. Kondziolka). He is someone who has done some of the most GK procedures in the United States.
I, too, heard the claims that CK had more success with hearing preservation than GK. I could only find the narratives that stated this rather than any hard research and literature to support the claim. Now, I only have my own experience to share. I had GK 15-months to the date. In this time, I lost 30% of the hearing in my AN ear within a month of my procedure, but my hearing has since stabilized, and I have lost no more hearing in the last 14 months. I feel fortunate in that regard. I've had to readjust some behaviors (ie, restaurant talk is mostly overwhelming, and I sit with my good ear "to" my audience; loud sounds still trouble me; and, I have intense tinnitus but had that before and after my procedure) but by and large am quite comfortable with my hearing preservation post-GK.
Those are only my individual experiences....I can't make any solid claims about the other doctors and only you can decide if CK or GK is the better approach. As anything, there are pros/cons but options tend to be good things...!
Wishing you only the best,
P.
