Abstract

Introduction: Sudden sensorineural hearing loss is commonly defined as sudden hearing impairement of more than 30 dB across three contiguous frequencies in less than 3 days and affects an estimated 5 to 20 per 100,000 people in a year. About the effect of cigaratte smoking on treatment results of idiopathic sudden sensorineural hearing loss, although there are only a limited information in several studies, as it is found that there is no study to investigate effects of smoking in various frequencies in means of decibel difference. We specifically evaluated hearing loss in different frequencies by examining the differences pre and post therapy between smokers and non smokers. This study is thought to be a first in this field.

Material and methods: This is a prospective study. Patients with pathology in magnetic resonance imaging, diagnosed vascular disease and diabetes mellitus, and patients over 65 years of age or under 18 years of age, patients who admitted to the hospital after 4 days and who received medical treatment before were excluded. Total of 72 patients were included in the study and divided into two groups as smokers and non-smokers. Whether patients had or didn’t have vertigo, degree of tinnitus, audiogram characteristics, 250 Hz, 500 Hz, 1000 Hz, 4000 Hz, 8000 Hz hearing tresholds and pure tone averages were recorded before and after treatment.

Results: No statistically significant difference found between groups in terms of age, sex differences, treatment start time, presence of vertigo and the degree of tinnitus. No significant between-group differences found in pre-treatment hearing tresholds, post- treatment hearing tresholds and hearing gains after treatment.

Conclusion: The effect of the smoking on recovery for each different frequency of hearing tresholds was not studied before. According to our results we are sharing the opinion that says smoking is not a risk factor or prognostic factor for sudden hearing loss. This can also be said for each different frequencies of hearing treshold.
