Diagnosing Cochlear “Dead” Regions and Its Importance in the Auditory Rehabilitation Process

Abstract: The identification of dead regions in the cochlea is used to obtain better results in the process of selection and fitting of hearing aids because the pieces of information generated by inner hair cells to the auditory nerve are important to better identify sounds, mainly those related to speech.

“…These divergent associations may be related to known gender differences in the auditory system with respect to hearing sensitivity and binaural tasks (McFadden 1998;Helzner et al 2005;Blanchet et al 2008;Ciletti & Flamme 2008;Kim et al 2010). The more pronounced high-frequency hearing loss in men could be associated with a greater number of cochlear dead zones, which makes the accurate fitting of hearing aids more difficult (Turner 2006;Padilha et al 2007). In the present study, the increased likelihood of men to report a low perceived benefit supports the possibility that men are more likely to have hearing aids that do not fit well than women.…”

“…Some have proposed that there is a need to limit high-frequency gain for most or all patients with moderate or worse high-frequency hearing thresholds (e.g., Turner, 1999; Yanz, 2002)). Padilha, Garcia, & Costa, (2007) recommended that amplification be “avoided” at frequencies where there are DRs. On the other hand, several investigators have reported that they were unable to determine any degree of high-frequency hearing loss above which it was not helpful to provide compensatory amplification, although DRs were not specifically measured in these studies (Horwitz, Ahlstrom, & Dubno, 2008; Plyler & Fleck, 2006; Turner & Henry, 2002).…”

“…Ainda, o estudo observou que não houve diferença estatística significante no número de células ciliadas externas de ratos com perda auditiva profunda quando comparados com o grupo controle, o que indica que a perda auditiva associada à infecção pelo vírus Zika não parece envolver células ciliadas cocleares danificadas, visto que as cócleas dos ratos com perda auditiva profunda se encontravam íntegras. Tal situação não condiz com a definição de perda sensorioneural, que é caracterizada por comprometimento das células ciliadas externas (CCE), podendo atingir também o funcionamento das células ciliadas internas (CCI) 26 .…”
