“…However, if the frequencies of the acoustic reflex are analyzed individually, it is observed that a large number of children presented absence of the acoustic reflex at the frequency of 4000 Hz, in both the ipsilateral and contralateral pathways. This information is consistent with a study that compared the results of acoustic reflex measurement with the results of figure-background testing and temporal ordering, which also found a higher number of altered acoustic reflex results at this frequency 31 . The occurrence of isolated absence of the acoustic reflex at 4000 Hz is high when compared with other frequencies.…”

Resumo: OBJETIVO: investigar os achados do teste Masking Level Difference com os resultados do reflexo acústico e a composição do sistema fonológico de crianças com transtorno fonológico, com o propósito de verificar se há associações que possam auxiliar a compreensão do processo de aquisição de linguagem atípica. MÉTODOS: estudo quantitativo, observacional e descritivo, desenvolvido por meio de levantamento secundário de um banco de dados, constituído de avaliações fonoaudiológicas de 110 crianças com transtorno fonológico, com idades entre 5 e 10 anos. Para a composição do corpus deste estudo o requisito utilizado foi a realização da timpanometria, com curva timpanométrica do tipo A (Jerger) e possuir avaliação do Masking Level Difference. RESULTADOS: dos dados de 110 crianças, 57 se enquadraram nestes requisitos, compondo a população deste estudo, sendo 42 do sexo masculino e 15 do sexo feminino. Destas 57 crianças, 23 (40,3%) apresentam resultado do Masking Level Difference normal e 34 (59,7%) apresentam resultado alterado. Não foi encontrada diferença estatística na relação entre o Masking Level Difference com as variáveis idade, sexo, grau de inteligibilidade de fala e o resultado do reflexo acústico contralateral e ipsilateral. Na relação entre a aquisição fonológica dos fonemas em onsetinicial e medial, foi encontrada significância estatística entre a não aquisição dos fonemas /s/ e /ʀ/ em onset inicial e /s/ e /z/ em onset medial com o resultado do teste alterado. CONCLUSÃO: outras habilidades do processamento auditivo, além da interação binaural, devem ser estudadas a fim de identificar a relação deste com o transtorno fonológico.

“…According to the literature, the action of the superior olivary complex regulates the contraction of intratympanic muscles and the skills involved in CAP. Thus, it is possible that changes in the acoustic reflex results stimulate the occurrence of alterations in auditory processing skills (19) . Besides the inner ear protection, the stapedial reflex arc is also related to the ability of sound location, speech detection, improved listening ability, improved speech intelligibility and noise attenuation in speech understanding (19) .…”

Besides the inner ear protection, the stapedial reflex arc is also related to the ability of sound location, speech detection, improved listening ability, improved speech intelligibility and noise attenuation in speech understanding (19) . It should be emphasized that the history of recurrent otitis, so prevalent in individuals with altered auditory skills (20) , may justify the alterations of contralateral acoustic reflex.…”

Purpose: To perform a descriptive analysis of the performance of patients referred to a public educational institution to take part in the assessment of auditory processing and to correlate the assessment findings to the variables of age and hearing complaints, also to correlate results to behavioral and electrophysiological assessments. Methods: The study included 159 individuals that were referred to the public health system to take part in an assessment of auditory processing. All participants underwent pure-tone audiometry, acoustic immittance measures, behavioral tests of auditory processing, and electrophysiological hearing assessment. Results: The main complaint was learning disability and the tests that presented higher prevalence of abnormal results were temporal processing and dichotic listening tests. In all electrophysiological tests the number of normal results was higher than the altered ones. The proportion of normal and abnormal individuals in behavioral and electrophysiological tests did not differ in relation to gender. There was weak correlation between auditory closure and right ear middle latency responses; between left ear middle latency responses and total middle latency responses; among temporal ordering and electrode effect and P300; between temporal processing and right ear middle latency responses; between dichotic listening and P300 and also between binaural interaction and right and left ears acoustic reflexes. Conclusion: The most frequent complaint among participants of this study was learning disability. Temporal processing and dichotic listening skills showed higher prevalence of alteration in the assessment. Most participants were referred to assessment of auditory processing by the speech-language pathologist. Correlation between behavioral and electrophysiological assessments was weak.Keywords: Speech, language and hearing sciences; Hearing; Auditory perception; Auditory perceptual disorders; Evoked potentials, Auditory; Hearing tests RESUMO Objetivo: Realizar uma análise descritiva do desempenho de pacientes encaminhados a um hospital de uma instituição de ensino público, para avaliação do processamento auditivo, e correlacionar os achados desta avaliação à idade, queixas, resultados e às avaliações auditivas comportamental e eletrofisiológica. Métodos: O estudo incluiu 159 indivíduos encaminhados pelo sistema público de saúde para avaliação do processamento auditivo. Todos os participantes realizaram audiometria tonal liminar, medidas de imitância acústica, testes comportamentais do processamento auditivo e avaliação eletrofisiológica da audição. Resultados: A principal queixa referida foi a de dificuldade de aprendizagem e os testes que avaliam processamento temporal e escuta dicótica foram os que apresentaram maior prevalência de alteração. Em todos os testes eletrofisiológicos, o número de resultados normais foi superior aos alterados. A proporção de indivíduos normais e alterados, nos testes comportamentais e eletrofisiológicos, não diferiu em relação ao gênero. ...

“…When comparing acoustic reflexes in the pre- and post-phases ( Table 3 ), we found no statistical difference, but it was possible to observe an improvement in responses post-operatively. The absence of the acoustic reflex is an indication of changes in the middle ear; however, due to the high complexity of the neural mechanism involved, the presence of increased threshold values and/or the absence of the acoustic reflex in individuals with tonal auditory thresholds within the standard normality may be associated with the presence of changes in language and auditory processing [ 36 ].…”

Palatine and pharyngeal tonsil hypertrophy may lead to dysfunction of the auditory tube due to a propensity for infection, potentially giving rise to otitis media. This is a quantitative and longitudinal study, developed from 2019 to 2021, at the State University of Campinas (UNICAMP). The studied sample comprised 15 participants aged 5 to 12 years (mean 7.9 years), 12 male and 3 female, arranged into two groups: children diagnosed with pharyngeal and/or palatine tonsil hypertrophy who were candidates for surgery (G1), and children who were later evaluated after surgery (G2). As part of the test, an otoscopy and measurements of logoaudiometry, pure-tone threshold audiometry, wideband tympanometry (ambient and peak pressure), and otoacoustic emissions (TEOAEs and DPOAEs, both at ambient and peak pressure) were all performed. There were statistically significant differences between phases in pure-tone audiometry, in terms of 226 Hz tympanometry, wideband tympanometry in peak pressure conditions, in the amplitude measurement TEOAEs in both pressure conditions, in DPOAEs in ambient pressure conditions, and in the signal/noise measurement in both pressures in DPOAEs. Overall, it was found that hearing tests were different for subjects with palatine and pharyngeal tonsil hypertrophy compared to the post-surgical group.
