I don't have it, but a number of relatives have or do have it. My grandmother eventually went deaf from it, but that was back in the 1940's when they didn't have any surgery to fix it. Several aunts also had it and had surgery back in the 1960's and the surgery lasted for about 20 years. Several cousins also had or have it and the one's that have had surgery, so far, so good. With hearing aids you can compensate for the loss as long as you can get the amplification high enough, but since otosclerosis is progressive, it might get to the point that you can't get the volume high enough. The one thing I can tell you is you want to have the surgery before it gets into the cochlear because once it's in the cochlear your ear is basically done. One other thing otosclerosis patients don't make good candidates for cochlear implants.
