The term 'full recovery' is a bit ambiguous when discussing acoustic neuroma surgery recovery.
The surgery almost always leaves it's 'mark' in some way but for the majority of AN surgery patients, the resulting deficits are relatively small and surmountable, as the many posts on these forums will show. Unfortunately some AN surgery patients have a slow recovery and some have issues that don't improve beyond a certain point. These folks can usually rise to the occasion and learn to deal with the deficit, although the emotional strain can be tough for some. Generally, the majority of AN surgery patients do well . Some compete in marathons and other strenuous physical activities and the majority return to their jobs, in due time.
My recovery was excellent. Although I'm retired and never engaged in strenuous physical activities (just mental ones) I feel as if I've pretty much returned to my normal life, although I have a bit less stamina than I did, but I'm 66 and some 'slowing' is to be expected at this age. I'm quite active and even though I have a few very minor deficits (invisible to others) I live a very rewarding life, in my opinion, doing what I want and feeling good while doing it, most of the time. I wish the same for every AN surgery patient but the reality is that no one can guarantee a trouble-free AN surgery recovery. We do our research, think hard about our choice in treatment, doctor, hospital, get as healthy as we can, have a positive attitude and then, we pray or at least hope for a good outcome...usually both.
