[The latency behavior of early auditory evoked potentials in high frequency hearing loss]

We evaluated the auditory evoked brainstem responses of 53 patients with unilateral or bilateral (79 ears) high-frequency hearing loss of cochlear origin, to see whether the reduction of I-V latency difference in high-frequency hearing loss that has been described by several authors, was present in our patients. We were able to confirm that in high-frequency hearing loss wave I-latency is significantly positively correlated with the degree of hearing loss. The I-V latency difference is significantly negatively correlated with the degree of hearing loss at 2000 Hz.
