Evaluation of Cochlear Functions in Renal Failure by “Pure Tone Audiometry
Journal Title: International Journal of Contemporary Medical Research - Year 2017, Vol 4, Issue 12
Abstract
Introduction: Chronic kidney disease (CKD) has been associated with hearing loss. The kidney and stria vascularis of the cochlea share physiologic, ultra structural and antigenic similarities that could underlie the link between CKD and hearing loss. Aim: The present study is taken up to study magnitude of SNHL in chronic kidney disease patients. Material and methods: 100 patients (200 ears) who had chronic kidney disease (CKD 5) and all patients underwent haemodialysis. All patients had Audiological evaluation with pure tone audiometry patients had sensorineural hearing loss. Results: high frequencies are affected in 52%, middle frequencies in 9%, low frequencies in 2.5% of individuals. 2.5% had hearing loss in all frequencies. Hearing loss is observed only at 8000 Hz in 10% of individuals. hearing loss was found in 61 (61%) members bilaterally. Unilateral hearing loss is present in 3(1.5%) patients. Hearing loss present in 62.5% individuals (125 out of 200 ears). Sensorineural hearing loss present in 62.5% in patients with chronic renal failure and severity correlated with duration of disease. No correlation between other co variables. Conclusions: It should encourage clinical nephrologists to include questions about hearing function in their preventive care protocols, to refer all patients reporting hearing loss to a hearing health professional for evaluation and/or rehabilitation (eg, hearing aids), and recommend that patients avoid further treatment with ototoxic medications to preserve their hearing ability.
