Sensorineural Hearing Loss in Patients with Chronic Renal Failure in the Patients of Southern India

Abstract

Aim: The study aims to evaluate the effect of hemodialysis on the hearing threshold in chronic renal failure patients (CRF).

Materials and Methods: This study was conducted at Government Medical College, Srikakulam from March 2022 to March 2023. Patients with CRF on chronic regular hemodialysis regardless of the duration of renal failure or dialysis were included in the study. All sociodemographic characteristics and history of the patients were collected. Hearing loss was detected by ontological examination and tympanometry.

Results: The study includes 76 patients with a mean age of 39.2 ± 7.1 years. Among the total population, 55 experienced hearing loss initially and was extended to 68 after 12 months of follow-up. At the end of follow-up, deterioration of hearing acuity occurred in 90% of patients and 6% of patients showed improvement. The study results also found a positive correlation between the period of hemodialysis and hearing loss. (r=0.712, P=0.0002)

Conclusion: Patients having chronic renal failure experience the most common condition called Sensorineural hearing loss.
