Impac tOf Alcoho lOn Auditory Threshold – A Cross Sectional Study.

[摘要] In general, approximately 2 billion of the world’s population consumes alcohol and 76.3 millionpeople have alcoholic disorders. Alcohol affects almost all organs of the body and causes cirrhosis,peripheral neuropathy, hypertension, myocardial infarction and also hearing loss. The aim of the study isto analyze the hearing loss in alcoholic men and non-alcoholic men by using Pure tone audiometry andsmart DPOAE. A total of 134 subjects (25 to 55 years) were included in the study, of which 67 alcoholicmen were in the study group and 67 healthy non- alcoholics were controls. The study subjects wereselected by an AUDIT questionnaire. Alcoholic men who were diabetic, hypertensive, smoker and subjectsusing ototoxic drugs were excluded from the study. Audiometric thresholds were recorded by using puretone audiometer and smart DPOAE. 44 out of 67 alcoholics and only 5 non-alcoholics were affected withsensorineural hearing loss (p<0.0001). There is a significant increase in auditory thresholds in alcoholics(p<0.0001). The results suggest that alcoholics were affected by high frequency (above 4 KHz)sensorineural hearing loss. The hearing loss is directly related to the duration, amount, type, occupationand age of alcoholics.
