No I do not have otosclerosis. I had had problems with a perilymph fistula which is a whole in the inner ear. This is why I have a profound loss in that ear. I have already had three surgeries and was just diagnosed with another fistula. I also have BPPV (benign proxamal positional vertigo). because of the chronic issues they felt the best course of action is the labyrinthectomy. Since I Have no useful hearing in that ear the laby is an option. I am not looking forward to it but it should help longterm.
