What causes canal dehiscence syndrome?

ANSWER

A few things can cause SSCD, including:

You can get SSCD in either ear. Some people have it in both. When that's the case, one ear typically causes more symptoms than the other.

  • A gene passed down from your parents that kept the bone in that area from growing thick enough
  • An infectious disease
  • Some form of trauma that damaged the bone
