I don't envy you the dilemma you're facing but from my understanding of the criteria for your choices, I would have to agree with Jan's opinion and go with Dr. Jho. He's a board-certified neurosurgeon, takes Medicare and is geographically closer. However, we all want a good outcome to AN surgery and if you're not completely comfortable with Dr. Jho for whatever reason (age, lack of recommendations, etc) then you'll have to seriously consider SBI and Dr. Shahinian.
As Jan pointed out, part of the problem with finding recommendations for Dr. Jho is due to the fact that endoscopic AN removal surgery is relatively new. When I mentioned it to my neurosurgeon 3 years ago, he had never heard of it, and this was a neurosurgeon that was very keen on embracing new approaches, as he did with my AN (debulking, then FSR). I suspect that Dr. Shahinian and SBI are a bit more aggressive in promoting their endoscopic AN surgery approach than Dr. Jho which may account for SBI having more information online. Just a thought.
As for age, while a very real factor in considering surgery, it is relative to the individual. I'm no athlete but when I underwent my AN surgery and radiation, I was 63 years old. Fortunately, I had none of the physical maladies common to those in late middle-age (arthritis, back and/or joint problems, diabetes, overweight, cardio issues, etc). That made me a good candidate for the AN surgery and I enjoyed a rapid recovery. However, what is true for me doesn't necessary mean it is true for anyone over 60 facing AN surgery. Your doctor usually decides whether you're a good candidate for the surgery, from a health perspective and most won't consider it if they believe you'll have a difficult time. Some doctors won't perform any kind of extensive surgery if the patient smokes. I have an acquaintance who needs back surgery. At age 65, he's a lifelong smoker. The neurosurgeon he consulted told him that he would not perform the surgery because this mans lungs are simply incapable of sustaining him through a 6 to 8 hour operation under 'heavy' anesthesia. That wasn't mere speculation. My acquaintance was required to undergo a lung capacity/function test - and he failed, miserably. Hence, no surgery. On the other hand, I don't smoke (I quit 20 years ago). My neurosurgeon didn't hesitate to schedule my AN surgery, based on my pre-op tests and my generally good state of health.
The point is that it's all relative to the individual. Although it is relevant, you can't generalize about your age and your body's ability to handle the trauma of AN removal surgery, . My 63 years (at the time of my surgery) might be more like 53 to a doctor's observation, based on my medical history and current tests. The same goes for any AN surgery patient. My recovery was quite brisk (I was motivated). Frankly, I think my neurosurgeon was a bit surprised. He had predicted 'months' to recover and I was driving again within 2 weeks. Granted, it took a lot longer to regain my full recovery but I managed just fine after a few weeks. Again, that's no indicator that yours - or anyone's - recovery will be identical. Just an observation for you to consider, along with other comments offered here, in good faith and with the intent of helping you see all sides as you journey toward a treatment decision.
