Background. The present study was undertaken to find the effect of moderate and heavy smoking on the audiovestibular profile.
Methods. This study was conducted at the Postgraduate Institute of Medical Education and Research, Chandigarh on 30 smokers divided into moderate (group II) and heavy smokers (group III) depending upon their smoking index and their audiovestibular profile was compared with age and sex matched controls (group I).
Results. Bilateral sensorineural hearing loss was found in 6 cases of group II and 12 cases of group III. The differences between the hearing loss (dB) for group I & II, II & III and III & I at all frequencies were found to be statistically significant (p<0.013), (p<0.025). The latent period was also found to be increased in group II and group III as compared to the normal. Total duration for right cold caloric (RCC) irrigation was found increased in groups II and III, whereas mean values of MSS were found to be decreased.
Conclusions. The conclusion is drawn that smoking may cause hypofunction of the labyrinth.
