Description
Aim: The aim of the present study was to find the prevalence of SNHL in type 2 diabetes patients and to find the
effect of duration and control of diabetes on hearing loss.
Methods: The present analytical cross-sectional study was conducted in Department of ENT for period of two
years. The present study was conducted on 100 type 2 diabetes patients and age and gender matched 100 nondiabetic controls in the age group of <50 years.
Results: In the present study, 68% were females and 32% were male. The mean age of patients of diabetic group
was 40.20 ±6.36, mean fasting blood sugar was 129.41±26.54, mean PP blood sugar was 170.20±40.25 and mean
HbA1c was 7.43±0.49. Mean age of patients of non-diabetic group was 38.52±7.43, mean fasting blood sugar was
107.03±3.16, mean post-prandial blood sugar was 128.52±9.81 and mean HbA1c was 6.006±0.222. The result
showed that only 28 patients had normal hearing and 72 patients had SNHL whereas 12 patients in this group had
minimal hearing, 19 had mild SNHL, 23 had moderate, 6 had severe SNHL and 12 patients had profound SNHL.
75 patients had DPOAE refer whereas 25 patients had DPOAE pass. Wave V grossly delayed in DM group as
compared to non-DM with all frequencies (i.e. 70, 80 and 90) whereas interpeak latencies of wave I-V at 70 db
frequency is almost equal in DM and non-DM group but it increase with increase in frequencies (i.e. 80 and 90
db).
Conclusion: This study concluded that the diabetics are at definite risk of developing auditory dysfunction,
therefore it is recommended that all newly diagnosed diabetic patients should undergo a complete audiological
evaluation at the time of diagnosis and a regular half yearly or yearly follow up is warranted for early detection
of damage to auditory functions. Although factors other than diabetes contribute to hearing loss, early glycemic
control for type 2 diabetic patients may reduce the incidence rate of this disease.
