case_images: Click Evoked ABR result with rarefaction and condensation polarities for the patient. The upper part of the figure shows the cochlear microphonics which are indicated in the circle line. The lower part are the control traces (no stimulus presented to patient) for controlling any stimulus related artifact.

case_images: The patient was followed up regularly with free field pure-tone audiometry, and her behavioral pure tone thresholds were within the range of 20-40 dB HL (Figure 3).
