Assessment of sensorineural hearing loss in well controlled and poorly controlled patients with diabetes mellitus

Abstract

Background: The prevalence of diabetes and its adverse effects have snowballed through the world due to changes in lifestyle. Association of diabetes with hearing loss has been a topic of discussion for many years. Aim and Objectives: To assess the Sensorineural Hearing Loss (SNHL) in patients with diabetes and correlate it with the duration and severity of hyperglycemia. Material and Methods: This hospital based cross-sectional study was carried out from August 2017 to July 2018 among 100 patients with diabetes aged between 31-60 years. Patients were grouped as per age, duration of Diabetes Mellitus (DM) and glycaemic control using HbA1c levels. The results were statistically analysed using Chi-square test and Pearson's coefficient to draw significance. Results: The incidence of SNHL in patients with diabetes was 79% and the correlation among different age group showed statistical significance (p < 0.05). There was no statistical association between the gender and hearing loss among patients with diabetes (p = 0.70). However, association of SNHL to the duration of DM was statistically significant when compared among all three duration groups. No statistical correlation was present with the glycaemic control of DM. Results showed high frequency SNHL with 41.8% patients with diabetes having moderate degree of hearing loss. Conclusion: Early referral for hearing assessment in patients with diabetes can be followed by clinicians aiming at improving quality of life with timely measures.
