Abstract :
ntroduction
Hearing loss is one of the under-recognized diabetic
consequences that impacts cognitive performance and
quality of life. The study was carried out to assess the
prevalence of hearing impairment and to investigate the
type, degree, and pattern of hearing impairment in
diabetics.
Materials and Methods
The study was conducted as a case-control study
including 60 diabetic patients and 25 healthy individuals
after exclusion of confounding factors. Hearing
assessment was done using pure tone audiometry.
Results
The prevalence of hearing impairment in diabetics of
age 30-60 years was 70% compared to normal population
(30%). 7 out of 13 diabetic patients in the age group of 30-
40, 19 out of 27 diabetics in the age group of 40-50 & 16
out of 20 diabetics in the age group of 50-60 had hearing
impairment. 18 out of 60 diabetic patients having HbA1c
of < 7 and 42 out of 60 diabetic patients having HbA1c of
>7 had hearing impairment. 24 out of 32 patients with
diabetes duration of <1 year, 7 out of 15 patients with
diabetes duration of 1-5 years, and 11 out of 13 patients
with diabetes duration >5years had hearing impairment.
Out of 42 diabetic patients who had hearing impairment,
27 (64%) had diabetic neuropathy.
Conclusion
Diabetics frequently suffer from eighth nerve
dysfunction. Its prevalence among diabetics increases
with age and correlates favourably with diabetes duration
and the presence of diabetic peripheral neuropathy. Its
prevalence, however, did not reveal a favourable
association with HbA1c levels
