Theory for presence of APT waves in SSCD patients. In SSCD, the brain pounds rhythmically on the dehiscent superior canal. These oscillations propagate sequentially through inner ear fluids, the oval window, and the ossicular chain. This generates rhythmic TM oscillation that may be detected as rhythmic waves on APT.
