4Cumhuriyet Üniversitesi Tıp Fakültesi, KBB, Sivas, Türkiye Smoking is an enjoyable habitual for years, therefore its increasing to make researc about the adverse effect of this habitual in the society. The adverse effect of smoking has not been controlled, therefore this problem will survive its important on public health. The adverse effect is not only on lung and predisposition of cancer but olso on the system likewise vascular system.
There are a lot of studies about the effects of smoking on hearing. Conventional hearing methods are mostly used in these studies.
Otoacoustic emissions (OAE) is low intensity and non linear acoustic signals which is produced by cochlear external hair cells and recorded via external acoustic meatus. Spontaneous (SOAE), transient evoked (TEOAE), stimulus frequency (SFOAE) and distortion products (DPOAE) are those four subgroups. Otoacoustic emissions recording is objective, simple, noninvasive, short and sensitive method.
In this sdudy we aimed to detect hearing level of smokers especially OAE and conventional methods?
Our study consist of patients and their relations which are chronic smokers between March 2003 and March 2004 in the department of Ear Nose Throat of Medical faculty of Cumhuriyet University. The patients was divided smoker and nonsmoker groups. Each groups was occurred 75 patients. The smokers consist of 75 patients that 45 male and 30 female. 34 adult male and 41 adult female. The study applied on 150 persons of 300 ears. Tympanometry, HFA (High Frequencies Audiometry), PTA (Pure Tone Audiometry) and OAE measurements were done on patients and the obtained data were compared statistically.
We found a statistically significant difference between smokers and control group for 10.000 Hz, 12.500 Hz, 16.000 Hz of high frequencies audiometry, average hearing level in 500 Hz, 1000 Hz, 2000 Hz frequencies of pure tone audiometry, signal-noise ratio and percentage of reproducibility of OAE ( p<0,05).
Finally smoking has adverse effects on hearing.
