Definitely BAHA
I was so impressed with the demo in my neurotologist's office (9 months post AN op) that I couldn't wait to get it. After I started wearing one, I was so impressed that I became a Cochlear volunteer so I could tell others just how great the BAHA is.
The implant surgery is something I've never regretted and I just celebrated my 3rd implant anniversary.
Like you, I have very good hearing in my "good" ear (100%) and I've found that the BAHA makes an incredible difference. I was totally miserable being SSD.
Lots of doctors have no concept of how well the BAHA works for their patients unless a) they wear one themselves or b) their patients tell them. When I was considering the surgery my doc told me that he'd implanted over 200 BAHAs and that only 1 of his patients was unhappy with the results. That spoke volumes to me (no pun intended). I figured with odds that good, I couldn't go wrong.
The BAHA generally won't give you directionality but some of us gain it as time goes on. I've found that I have it - or least think I do.
The implant surgery is a piece of cake - done on a outpatient basis; I even had mine with local anesthesia while wide awake. My doc does use general anesthesia if a patient wants that.
The BAHA isn't for everyone, but I chose it because I was impressed by the demo, I felt I was too young to not do something about my SSD, and I didn't want to wear something in my ear (like a TransEar).
If you have any other questions - or concerns - don't hesitate to ask them on the Forum or feel free to PM me.
Best,
Jan
