High frequency audiometry and chronic renal failure

High frequency audiometry with pure tones from 9 to 18 kHz was performed in 37 patients with chronic renal failure undergoing conservative medical treatment and in a control group of 96 patients (age range 30-59 years for both groups). It was noted that the high frequency thresholds were significantly higher for the patients with chronic renal disease, and further deterioration of hearing function was observed at the examination performed after 1 year of follow-up. It was concluded that high frequency audiometry is a sensitive method for detecting hearing changes in patients with chronic renal failure and can be used to monitor these patients.Univ Fed Sao Paulo, Escola Paulista Med, Dept Otolaryngol & Commun Disorders, BR-04023900 Sao Paulo, BrazilUniv Fed Sao Paulo, Escola Paulista Med, Dept Otolaryngol & Commun Disorders, BR-04023900 Sao Paulo, BrazilWeb of Scienc
