I agree with you on that one to post the pros and cons. Thre are a few type of cochlear implants. 1. Med-el, 2. Nucleus Freedom, 3. Baha implants, and 4. Bilateral implants is all I heard so far.
THe CI's are freedom, med-el and advanced bionics auria.
a baha is a bone anchored hearing aide. They place a peg in your skull allow the bone to grow around it for a few months then attach the HA part to the peg. They are used when the middle ear is the problem and the cochlea works well.
The bilateral is either two hearing aides, two baha's or two ci's.
