Sorry I'm just getting around to reading your post, Stoneaxe. I've been off of the forum for a few days.
Anyway, IMO the BAHA is an incredible way to deal with hearing loss - and no, you don't have to have AN surgery to qualify for one. The only requirements are 1) you are completely deaf in one ear (unilaterally deaf) and 2) you have some hearing in the other ear. It doesn't matter how you came about being deaf - it can be congenital, due to an AN, etc.
I had my surgery on 3/4/08 and it was literally a piece of cake. It took about 90 minutes from start to finish and a lot of that time was spent just having my head draped with lots of sheets in the outpatient OR. I was awake during the entire procedure - in fact, spent some quality time joking around with my doctor while he shot my head with lidocaine, drilled the hole in my skull, etc. After he was done with the implant, I could have walked out of the OR if they would have let me. It was that simple. Absolutely NOTHING like AN surgery. I went out to lunch after the procedure and then to my son's volleyball game - all while sporting my very chic "BAHA hat" (pictures posted on the forum somewhere).
My BAHA site healed without a glitch in 90 days and I got my processor on 6/4/08. It was a red-letter day - heard lots of stuff I'd been missing in the 9 months post AN surgery
Would I do it again? In a heartbeat. I was blown away by the BAHA demo and I am not a bit disappointed by the real thing. It has been a very positive improvement in both my personal and my business lives.
Is the BAHA for everyone? Quite frankly, no. Some people just don't want a titanium post drilled into their skull and I totally understand that. But that isn't an issue for me. I like the way the processor is covered up by the hair on my head. A hearing aid in my ear just isn't for me.
As everyone else said, the BAHA won't give you back your "normal" hearing - nothing will - but IMO it's the next best thing. I am definitely biased though - a TransEar user might make the same claim.
I'd recommend trying the demo and going from there. You might want to also PM some forumites who haven't responded to this post yet - Sam Rush, joef, Ellis - they all helped me in my decision making process. Answered lots of questions that I'm sure they rolled their eyes at too
but they were great.
