Abstract:

OBJECTIVE: To determine the response level of the EOA-DP conventional frequencies (FC) and ultra high frequency (UAF) in smokers. METHODOLOGY: The sample consisted of 10 smokers between 19 and 29 years (mean 23.4), being 07 females and 03 males. These individuals started smoking around 15 years old and over time have been gradually increasing consumption of cigarettes, up to smoking a pack a day (average 8 years of smoking). All subjects underwent an initial interview, visual inspection of the MAE, ATL, tympanometry, EOA-DP in CF and UAF. RESULTS: The results showed ATL and impedance within normal OAE-DP-FC noticed a small difference between the ears, but there was a tendency of OE has better S / N. Regarding OAE responses UAF-DP can be noted that had lower response, and the frequency was increased as a decrease in cochlear response. CONCLUSION: There are no national studies on OAE in UAF-DP and the existing international studies are few in number, probably because there was little equipment available in the market and being a new procedure, and there is no standardization in relation to normal and there is little knowledge regarding the use of OAE-DP in the range of 9,000 to 16,000 Hz in clinical practice. Therefore, it is essential that further research to investigate the applicability and contribution of EOA-DP in UAF in clinical practice, especially in populations at risk to develop changes in cochlear UAF as the population of smokers.
