Merle -
which surgical approach did you have?
If it was translab, changes are you're SSD permanently. Retrosigmoid you may or may not be - but probably are. Mid-fossa would have given you the biggest chance of keeping your hearing.
Your doc should know. Did he say anything about your hearing nerve being destroyed during surgery? Hearing nerves don't regenerate like facial nerves do. If it was destroyed, you are permanently SSD.
The BAHA is incredible and I highly recommend it. I had my implant surgery almost 2 years ago and consider it one of the best things I've done.
BAHAs rock
