“…The (EOA) method consists in recording the sound energy generated by the cells of the cochlea in response to the sounds emitted in the external acoustic meatus, allowing study of the mechanical aspects of the cochlear function of objectively before hospital discharge 4 . In programs of neonatal auditory screening, the quantity of infants with normal hearing who present EOA absent, when tested in 48 hours after birth, is a complex issue, and is being discussed by health professionals.…”

OBJETIVO: investigar o nível de consciência dos pais em relação à importância da triagem auditiva neonatal, bem como verificar os motivos do não comparecimento ao retorno agendado após a primeira avaliação. MÉTODO: a casuística foi constituída por 31 mães e/ou responsáveis dos recém-nascidos da unidade neonatal do Hospital Universitário de Maringá, os quais não compareceram ao reteste agendado após a alta hospitalar. RESULTADOS: os motivos apresentados pelas mães e/ou responsáveis para o não comparecimento ao retorno agendado envolveram atitudes que puderam sinalizar pouca importância atribuída às questões relacionadas à audição e a Triagem Auditiva Neonatal, pois sugiram motivos irrelevantes como o esquecimento do retorno, mãe pensou que o bebê não deixaria ser submetido ao exame e a perda de horário para nova avaliação. Tal fato, provavelmente reflete a falta de conscientização por parte das mães dos recém-nascidos quanto à importância da Triagem Auditiva Neonatal. CONCLUSÃO: existe a necessidade de aumentar a conscientização geral em relação à Triagem Auditiva Neonatal, por parte dos familiares e dos profissionais que atuam diretamente com os recém-nascidos, os quais contribuirão para a agilidade do processo diagnóstico, garantindo melhores perspectiva ao futuro de crianças portadoras de deficiência auditiva.

“…They are widely used for hearing assessment (1)(2)(3)(4) . These tests provide information regarding the mobility of the tympanossicular system by presenting the pressure in the external auditory canal (tympanometry) and the contraction of the stapedius muscle when stimulated by highintensity sounds (acoustic reflex) (5,6) .…”

“…At the point where the magnitude of the acoustic admittance is maximal, there is a pressure peak in tympanometry and, under these conditions, with the same probe tone, the acoustic reflex is analyzed (7)(8)(9) . The acoustic reflex is defined as the lowest stimulus intensity able to produce a detectable change in acoustic admittance (5,6,10) . The analysis of the presence or absence of Acoustic Stapedial Reflex Threshold (ASRT) may indicate a middle-ear dysfunction, significant cochlear hearing loss, retrocochlear pathology, or dysfunction in the facial nerve (11)(12)(13)(14) .…”

PURPOSE: To analyze the occurrence of acoustic reflex and its threshold on newborns using the 226 and 1,000 Hz probes. METHODS: Thirty-six newborns with "PASS" results in newborn hearing screening and tympanogram with one or two peaks for both probe tones were included. Group I comprised 20 full-term newborns without risk indicator for hearing loss, and Group II comprised 16 newborns with at least one risk indicator. The study about ipsilateral acoustic reflex thresholds was conducted in 500, 1,000, 2,000, and 4,000 Hz. RESULTS: The groups presented the acoustic reflex thresholds between 50 and 100 dB for both probe tones. In the comparison between the probes, there were differences in all frequencies evaluated in Group I, with the lowest threshold mean for the 1,000 Hz probe. In Group II, differences were detected at 2,000 Hz. The mean acoustic reflex thresholds were similar in both groups for the 226 Hz probe. There was a difference for the 1,000 Hz probe in all tested frequencies. The percentage of response was higher in both groups for the 1,000 Hz probe. The kappa test showed extremely poor agreement in the comparison of results between both probes. CONCLUSION: The occurrence of acoustic reflex was higher in newborns and its thresholds were lower with the 1,000 Hz probe both for healthy newborns and for newborns at risk.

Congenital hypothyroidism as a risk factor for hearing and parents’ knowledge about its impact on hearing

Aim To evaluate the hearing of children with congenital hypothyroidism (CH) and to analyze the knowledge that parents’ have on the possible auditory impacts of the disease. Methods A total of 263 parents/guardians were interviewed about aspects of CH and hearing. Audiological evaluation was performed on 80 participants, divided into two groups: with CH (n= 50) and without CH (n=30). Clinical and laboratory CH data were obtained from medical records, pure tone auditory thresholds and acoustic reflexes were analyzed. The auditory data was compared between groups. Student’s t-test and Chi-square were used for statistical analysis at a significance level of 5% (p ≤0.05). Results The majority (78%), of the parents were unaware that CH when not treated early is a potential risk to hearing. There was no correlation between socioeconomic class and level of information about CH and hearing (p>0,05; p=0.026). There was a statistically significant difference between the auditory tone thresholds of the groups and between the levels of intensity necessary for the triggering of the acoustic reflex. The group with CH presented the worst results (p≤0.05) and absence of acoustic reflex in a normal tympanometric condition. Conclusions Children with CH are more likely to develop damage to the auditory system involving retrocochlear structures when compared to healthy children, and that the disease may have been a risk factor for functional deficits without deteriorating hearing sensitivity. The possible impacts of CH on hearing, when not treated early, should be more publicized among the parents/guardians of this population.
