Abstract

We tested the hypothesis that hearing loss in superior semicircular canal dehiscence (SCD) syndrome is due to a “third cochlear window”. SCD in human temporal bones produced a fluid motion in the dehiscence, a reduction in round window velocity comparable to the low-frequency hearing loss seen in SCD patients, and an increase in stapes velocity; all these results support the “third window” hypothesis. A functionally- and anatomically-based model predicts the temporal bone results.
