ABSTRACT

The objective of this work was to evaluate the relationship between brainstem auditory evoked potentials (BAEP) and transient otoacoustic emissions (TOAE), and to establish which variables of these studies are used in the patient´s evaluation when existence of retrocochlear dysfunction is suspected. In a retrospective and traverse study, 37 subjects of both sexes were analysed. They had been sent to the Neurophysiology Department at the Institute of Human Communication, between January 2002 and August 2003, and their referral diagnosis was to discard retrocochlear dysfunction by means of BAEP. They were subjected to TOAE in both ears, carried out the same day as the BAEP. The study was based on the analysis of interwave intervals, latencies, and the thresholds of the BAEP, as well as the total percentage of reproducibility and that of the TOAE´s frequency band. The statistical tools were measurements of central tendency, Student´s t, and correlation analysis. The results showed that there is no direct correlation between the BAEP and the TOAE; however, both studies supplemented each other quite well. By analyzing the percentage of total reproducibility and the one for the band of frequencies, we observed that this parameter is most accurate to see if the cochlea is affected and where, so we conclude that when retrocohlear dysfunction is discarded by means of the BAEP, it is convenient to correlate the result ofthe function latency/intensity with the reproducibility for each frequency band of the TOAE.
