Help! Otosclerosis or Superior Canal Dehiscence?

To find out if you have superior semicircular canal dehiscence, you must get a CT of the temporal bone which shows the semicircular canals and whether or not they are covered with bone. If the bone is missing, which is what I have, you can have vertigo, imbalance, tinnitus, ear pressure and you might hear your heartbeat or other body sounds in your ear.
