In this study, the origin of hearing loss in patients with chronic renal failure (CRF) and the effect of dialysis type on hearing loss due to CRF was investigated. For these purposes, 40 patients with CRF (20 in hemodialysis and 20 in peritoneal dialysis program) were examined for hearing acuity by pure-tone audiometry (PTA), Threshold tone decay (TTD) test and Auditory brainstem response (ABR). The hearing loss (13 cochlear, 10 retrocochlear in TTD test), was found in 57.5% of patients. ABR findings showed that III., V. absolute latencies and I-III., III-V interpeak latencies were significantly longer in hemodialysis group than control group. No statistical significance was found between hemodialysis and peritoneal dialysis groups in audiological and ABR findings. Significant changes were not also observed before and after hemodialysis. It is concluded that both cochlea and retrocochlear region are susceptible to the effect of uremia. The type of dialysis has not affected the degree of hearing loss in CRF patients.
