Abstract: Brai nstem Evoked Response Audiometry (BERA) is an objective and non-invasive method of hearing assessment which detects electrical activity from the inner ear to the inferior colliculus. Aim: To assess the hearing pathway in normal hearing individuals and compare differences associated with gender, age and ear side (left and right). Study Design: A retrospective study. Materials and Methods: Sixty normal hearing individuals, aged between 09 and 66 years old, were subjected to clinical ENT examination and audi… Show more

“…The studies that consider the possibility of this influence report that it occurs mainly in the absolute latency of wave V (14,20) -a delay that was observed in one of the patients studied at the age of 61 years. Conversely, other studies indicate that this impairment can occur in any absolute latency, with preservation of the interpeak intervals -characteristics also observed in one of the participants of this study (20,21) . This increase in latency suggested by some authors, either only in wave V or in all absolute latencies, would occur as a consequence of degeneration of the auditory pathway until the brainstem caused by the aging process.…”

“…Another controversial point in the BAEP is the influence of gender in the parameters of this assessment. Some studies did not find significant differences between genders (16,18) ; however, other authors have stated that the male gender presents higher latency of wave V and I-V interpeak interval compared with those of the female gender (21,22) . In the present study, the patient who presented impairment in the latency of wave V was male.…”

“…The most frequent is the response latency, the most characteristic potential and the anatomical origin of the responses at the auditory system level (2) . ABR, the short-latency auditory evoked potential, consists of the recording of the electrical activity in the auditory system, in response to an acoustic stimulus (3) . The classification of bioelectrical activities is based on the time elapsed between the introduction of the acoustic stimulus and its appearance (latency), which are analyzed in a millisecond (ms) time--frame.…”

“…Wave I is generated in the distal portion of the brainstem to the auditory nerve, wave II is generated in the proximal portion of the brainstem to the auditory nerve 4,5 . Waves I and II are generated in the cochlear nerve and subsequent DOI: http://dx.doi.org/10.7322/jhgd.106001 have multiple generators, although there is no precise definition of the contribution of the structures for the appearance of each power.…”

“…However, studies have shown that wave III is generated in neurons that emerge from the cochlear nucleus complex 2 , the wave IV by the superior olivary complex and peak which represents the wave V is generated by the contralateral inferior colliculus cells 6 . The wave VI is generated in the inferior colliculus and the wave VII in the medial geniculate nucleus (4,5) . It should be emphasized that the peaks of the waves IV, V, VI and VII of the BAEP have complex origin, with more than one anatomical structure contributing to the formation of each peak.…”
