Pat -
thanks for your kind words
Generally the good ear won't compensate for the bad one. This happens with balance, but unfortunately, not with hearing.
I used to think that BAHA candidates had to be 100% SSD, but a few months ago my neurotologist told me I was wrong. BAHA candidates have to have a "significant" hearing loss on one side. I don't remember the percentage he gave me, but at 75% you may be a candidate. You should ask the surgeon who did your AN surgery (if he does BAHAs) or ask your audiologist.
If you are a candidate, there is a BAHA demo you can try. It will give you a good idea of what the BAHA will do for your hearing - although the real thing is even better.
Most insurance companies don't cover hearing aids, but the BAHA is not a hearing aid - technically it's an implant or a prosthesis. This is a very important point - and one that must be stressed when seeking insurance coverage. Insurance companies have a reputation for turning down BAHA coverage requests, so if you approach yours, you need to have your doctor send them information telling what a BAHA is and why you need it. It's not unusual for the first insurance request to be turned down, but persistence usually pays off.
Also, if your insurance company covers Cochlear implants, you have a wonderful case for BAHA coverage. Cochlear implants are to bilateral (double-sided) deafness as BAHAs are to unilateral deafness (SSD).
I fortunately don't suffer from tinnitus, so I don't know if a hearing aid would offset that or not. Before I got my BAHA I asked my neurotologist if it would cause me to get tinnitus and he said it would not. I believe he also told me that if I had tinnitus, the BAHA wouldn't stop it.
