DD having mastoidectomy in a couple of weeks. What can you tell me??

[elsma]

I'm really anxious about this. I've been told a five-hour op. She's 9 and otherwise healthy. Just hate the thought if it really... and not knowing what to expect. Any experience? How long to recover? Is nausea common (being an ear thing, I hear they can get dizzy)? Any insight or stories would be helpful. Drs just tell me everyone's different (yeah, I know that, but what's in the bounds of normal?!)
Thanks.
