Tim -
don't be fearful of the implant surgery; it's absolutely NOTHING like AN surgery (thank God).
It's a simple, outpatient surgery, and can even be done with local anesthesia. I opted for local and was wide-awake during my procedure. Over 90% of my docs' patients choose local, but he does use general anesthesia if that's what they prefer.
From start to finish, the surgery is about 90 minutes and a lot of that time is spent prepping you (lots of drapes). Post op I went to lunch with my sister and attended my son's volleyball game at the local junior high school. I drew a few funny looks - since my head was wrapped in mastoid bandages - but other than that I was "normal".
I returned to work two days after surgery; would have gone the next day but wasn't allowed to take off my lovely bandages until that afternoon. Figured my co-workers might be freaked out by it, so I waited until day 2.
As for directionality, I meant being able to hear exactly what direction sound is coming from. With my BAHA, I have a general idea, but am often not precisely correct. For example, if sound is on my deaf (left) side, and I'm wearing my BAHA I am aware that it's coming from the left, but I can't say 100% if it's located immediately to my left (as in right next to me) or behind me towards my left side. Hope this makes sense.
From the first day I started wearing my processor, I've had the "sense" that my directionality was perfect, but the study I participated in proved me wrong. The results of the study were conclusive that BAHAs don't give the wearer's directionality, although most feel like it does. So, in short, it's an illusion. A very nice one, though.
