- •
In superior canal dehiscence (SCD), the amplitudes of AC and BC-evoked cVEMP reflexes usually saturate whereas oVEMP amplitudes do not.
- •
Thresholds for AC-cVEMPs and BC-oVEMPs and amplitudes of AC-oVEMPs and cVEMPs (at 105 dB pSPL) separated SCD with sensitivities of over 83% and high specificity.
- •
In contrast, AC oVEMP thresholds and BC cVEMP thresholds and amplitudes showed 62% or lower sensitivity in detecting SCD patients.
