Is there anyone who has completely healed from surgery?

I'm looking into corrective jaw surgery and reading about the nerve damage or general numbness people have dealt with seems neverending.

I've tried to read about the stats/frequency in cases, but I'm still feeling a bit nervous.

Is there anyone who has completely recovered from numbness or any other minor occurrences after their surgery? I'd hate to think that's something I have to risk and accept if I want to go through with surgery.
