Estudo de caso: neuropatia auditiva

Abstract: Atualmente, podemos complementar os resultados encontrados na audiometria convencional com os obtidos nos exames eletrofisiológicos, o que nos permite diagnosticar não apenas uma perda auditiva periférica, mas também diferenciar uma perda auditiva coclear da neural, ou central. Isto nos conduziu a um grupo novo de pacientes que apresentava alteração na sincronia neural com função normal das células ciliadas externas. Esta patologia é conhecida como Neuropatia Auditiva. O objetivo deste estudo é descrever as ca… Show more

“…In our study, all subjects diagnosed with ANSD met the criteria for preserved cochlear function associated with altered or absent auditory nerve function according to OAE and BAEP testing, respectively. Test results were consistent with the findings described in the literature in regards to gender distribution, age range, and degree of hearing loss 25 , 26 , 27 . Only three (11.6%) of the 27 individuals with ANSD had some functional gain after they were fitted with hearing aids, revealing the unsatisfactory outcome of this intervention.…”

“…Interestingly, in-depth audiology testing in the acquired cases of Zika-related HL suggested the presence of a sound processing disorder called auditory neuropathy. 75,76 The association of Zika with this type of retrocochlear HL has important public health implications because auditory neuropathy is not identified with typical methods of hearing screening. Hearing loss in congenital Zika cases was commonly reported in children older than 1 year, suggesting that Zika may lead to delayed onset of HL and emphasizing the need for recurring screening beyond the newborn period.…”

“…Some authors have reported that, when normal OAEs are observed, with some alteration in the central auditory pathways, it can be due to retrocochlear alterations. That is, hearing compatible with normal cochlear function presenting with neural synchrony changes, can be classified as a neuropathy (7) . As such, it is verified that this definition is compatible with the characteristics observed in both cases in this study.…”
