Proportion of Hearing Loss in Chronic Renal Failure: Our Experience

Abstract

Introduction: This study is taken up to study the magnitude of sensorineural hearing loss (SNHL) in chronic kidney disease (CKD) patients. Two hundred patients (400 ears) who had CKD 5 and all patients underwent hemodialysis were taken into study. Methods: All patients had clinical ENT examination and audiological evaluation with pure tone audiometry and impedance audiometry. All patients had SNHL. Results: In summary, high frequencies are affected in 52%, middle frequencies in 9%, and low frequencies in 2.5% of individuals. About 2.5% of patients had hearing loss in all frequencies. Hearing loss is observed only at 8000 Hz in 10% of individuals. Among all patients, 21 patients (42 ears) underwent a renal transplant, and post-transplant duration was about 1 year, 11 patients (57%) having hearing loss. Thus, hearing loss was found in 122 (61%) members bilaterally. Unilateral hearing loss is present in 5 (2.5%) patients. Conclusion: Hearing loss is present in 63.5% individuals (249 out of 400 ears). Thus, SNHL is present in 63.5% in patients with chronic renal failure and severity correlated with duration of disease. No correlation between other covariables.
