Abstract
Auditory brainstem responses (ABR) were analyzed in 2 boys with I-cell disease. Both patients showed a prolonged latency of wave I, a normal I-V interpeak latency and an elevated threshold of wave V. The intensity-latency curve had a steep slope. These abnormal ABR findings reflect the presence of conductive hearing impairment associated with the cochlear component in I-cell disease.
