What is canal dehiscence syndrome?

ANSWER

It’s also called superior semicircular canal dehiscence syndrome (SSCD). It’s a rare disorder that affects your balance and hearing. Dehiscence means hole. If you have SSCD, you have a hole or a very thin place in the bone in your ear that helps your body balance itself. It also can cause problems with the way sound comes into your ear. People usually learn they have it in their 40s.
