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 heå.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 heå loss. CONCLUSION: From best of our knowledge, this study is first to investigate the risk of heå loss in patients with atherosclerosis. So dedicated research is required on larger samples.
