Association of cigarette smoking with hearing loss: Cross sectional study among sample population of Kolar
Journal Title: Medpulse International Journal of Physiology - Year 2018, Vol 7, Issue 1
Abstract
Background: The link between cigarette smoking as a risk factor for hearing loss was established over 40 years ago. This study was an attempt to observe the association between smoking and changes in hearing thresholds in a sample population of Kolar. Aims and Objectives: To record the auditory thresholds for various frequencies of smokers and age matched non-smokers and to study association of pack years of smoking with changes in auditory thresholds for both AC and BC at different frequencies Methodology: The study included 50 male cigarette smokers of age group between 20-40 years and 50 age matched male non smokers, who were selected based on inclusion and exclusion criteria. An assessment of auditory thresholds was done for different frequencies by using pure tone audiometer (ELKON-GIGA3) for both study and control groups in a sound proof room. The data collected was entered in master chart and statistically analyzed. Conclusion: The present study revealed that, smoking causes increase in both air conduction and bone conduction thresholds at all frequencies and if a subject has smoked regularly for a period of 2 or more years it induces changes in both auditory air and bone conduction thresholds.
