BB -
congrats on getting approval
I got my BAHA implant 9 months post (AN) op and couldn't live without it. I started w/a Cochlear Divino and upgraded to a Cochlear BP100.
Initially it is strange to have the abutment on your head, but you quickly get used to it (usually by the time your BAHA site has healed). Soon it becomes just a part of you; I liken it to someone who wears glasses or contact lenses. You get to the point where you aren't even aware of it on a day to day basis.
Don't be afraid of the surgery. It's minor - especially compared to AN surgery. It's typically done outpatient and lasts about 90 minutes; a good part of that time is spent by the nurses draping you so the site area stays sterile. I had my implant done with local anesthesia while wide awake, but most docs give you the option of local or light general anesthesia.
If you have any questions, just ask. Happy to help.
