Abstract


INTRODUCTION: If some known risk factors for atherosclerosis like age, gender, obesity, diabetes ,blood pressure,
dyslipidaemia, chronic kidney disease, high-sensitivity C-reactive protein (HSCRP), smoking and alcoholism are used
as diagnostic tool to predict and access the nature and severity of SNHL atherosclerotic patients , significant morbidity
and mortality can be averted by simple audiometric screening because atherosclerotic restriction of blood supply of
peripheral and central auditory pathways can reflect itself in audiometry. The present study was designed to study the
correlation of etiologies of atherosclerosis contributing SNHL and to study the magnitude and type of SNHL of common
contributing factors for atherosclerosis.
METHOD: This prospective was done on three thousand five hundred and seventy six (3576) atherosclerotic patients
(age group 20 – 55 years) attending the out-patient department with documented presence of positive risk factors. Age
was limited to 55 years to exclude presbycusis. Atherosclerosis was measured from mean carotid intima-media
thickness and the presence of carotid artery plaque. All patients had otoscopic examination and standard pure tone
audiometry. Descriptive statistical analysis was done.
RESULT: Majority of the patients had combination of risk factors.184(5.1%) patients had normal hearing.1876 (52.4%)
had mild SN loss,954 (26.6%) had moderate SN loss and 546 (15.2%) had moderately severe SN loss. Only 11
patients(0.3%) had severe SN loss and 5 patients(0.1%) had profound SN hearing loss.
CONCLUSION: From best of our knowledge, this study is first to investigate the risk of hearing loss in patients with
atherosclerosis. So dedicated research is required on larger samples
