In my experience, stats with AN are crazy. There are so many factors, it's hard to give an accurate answer. To be honest, the numbers don't look reasonable. 2.5% for permanent paralysis and the same number for ANY weekness? I would think the later to be higher.
In the end, I would agree a prior surgery would increase the risk but this would be hard to quantity.
My advice. Once you choose your treatment, put your faith in your medical team and block out the noise.
BTW - my facial nerve was removed during surgery. Based on all my reading I thought this was a worse outcome than death especially for a single 47 year old man. However, after a year I'm doing great with a high quality of life.
Since you already had surgery you know the pitfalls of the AN club. It's really hard to predict our list of issues. All we can do is deal with them when they arise.
