I'm about your age (49) and had translab in July. My hearing was about shot by then so the SSD while worrisome was not going to make a huge difference.
I'm now coming up on 4 months out. My experience was 'good, but with challenges'. Good because the surgeons were excellent, so there were no facial paralysis issues or CSF leaks or such. I was not ready for the challenges around balance and fatigue, though. As I'm writing it's Sunday afternoon and I'm feeling pretty wiped out. That said I started a weightlifting program a couple months back, and I'm definitely able to do it without room spins, and 'hope is alive' I'll be able to get back to the level of running I was at pre surgery, though I'm not there yet.
Overall I'm glad I did surgery, I'd say. Tinnitus was really bad before, now I don't have it. I was having balance and fatigue issues before - I just didn't know to make the connection. I was having pains in my face due to the facial nerve being increasingly compromised, now I know I'm past the danger there. I'm hopeful that although this is a slow process, although I'm at a 'new normal', I'll still be able to do stuff and feel gradually more and more 'like myself again'. Had I not had surgery, who knows, misfortune might have found me in a place where, some years in the future, I didn't have good insurance or a reasonably understanding employer. Everybody's experience is different, just throwing my experience into the mix. Definitely wish you well on your journey and that you get the best care for your particular case.
