“…Vernix in the external acoustic meato is a serum substance that coats the skin of newborns and can be seen by the otoscopic examination. Chang et al (1993) found 15% of imperfections in the hearing screening by means of TOAE and verified an increase of the occurrence of "passes", after-cleanness of vernix (from 76% to 91%).…”

TEMA: perda auditiva em neonatos. OBJETIVOS: verificar a prevalência de alterações auditivas em neonatos do Hospital São Paulo, observando se há correlação com as variáveis: peso de nascimento, idade gestacional, relação peso e idade gestacional e fatores de risco para deficiência auditiva. MÉTODO: realizou-se uma análise retrospectiva dos prontuários de 1696 recém nascidos, sendo 648 nascidos pré-termo e 1048 a termo. Todas as crianças foram submetidas à avaliação audiológica constituída por pesquisa das emissões otoacústicas transientes e do reflexo cocleopalpebral e medidas de imitância acústica, estabelecendo-se o diagnóstico do tipo e grau de perda. RESULTADOS: a perda auditiva neurossensorial foi identificada em 0,82% das crianças nascidas a termo, e 3,1% das crianças pré-termo (com diferença estatisticamente significante). A perda auditiva condutiva foi a mais freqüente nas duas populações sendo observada em 14,6% das crianças nascidas a termo e 16,3% das crianças pré-termo. Houve suspeita de alterações do sistema auditivo central em 5,8% das crianças pré-termo e 3,3% das crianças a termo. Na população de crianças nascidas a termo, houve correlação significante entre falha na triagem auditiva e os riscos antecedente familiar e síndrome, sendo 37 vezes maior a chance de uma criança com síndrome falhar na triagem e sete vezes maior a chance de falhar na orelha direita quando esta tiver antecedente familiar de perda auditiva. Quanto menor a idade gestacional (< 30 semanas) e o peso ao nascimento (< 1500g), três vezes mais chance de falhar na triagem auditiva. CONCLUSÕES: houve maior ocorrência de perda auditiva nas crianças pré-termo de UTI neonatal. A idade gestacional e o peso de nascimento foram variáveis importantes relacionadas na probabilidade de falha na triagem auditiva. Houve correlação entre o fator de risco síndrome e a perda auditiva neurossensorial em crianças nascidas a termo.

“…The stimulus intensity used in the present study is similar to that used by other authors [14][15][16][17][18]. The stimulus stability, measured as percent pressure variation every 3 s and compared to the initial one, should be greater than 75% [15,19].…”

“…The technical factors able to significantly influence the results of the test are the coupling between the probe and the external meatus [9], the noise [17] and less frequently, a middle ear effusion [15,39] that was present in 9% of cases without significant differences within the first days of life [40]. These authors observed that the prevalence of occlusion of the external meatus due to vernix caseosa was 14.3% within the first 24 h, decreasing to 11.7% between the 25th and the 48th h, while only 45% of new-borns showed a clean meatus during the first day of life.…”

Objecti6e: Early diagnosis and rehabilitation of congenital hearing loss are mandatory in order to achieve a satisfactory linguistic and cognitive development. A universal hearing screening in order to identify congenital hearing losses before 3 months of age is required. Methods: TEOAEs are an easy to perform, short lasting, not invasive and low-cost test with a high sensitivity. 320 at term new-borns (640 ears) without any risk factor for hearing loss underwent TEOAEs. The new-borns were screened 3 days after birth. Those who failed the first test were retested when possible before the discharge from the hospital. ABR was performed 3 months later in cases who failed TEOAE. Results: The median TEOAE sampling time was 98 s, the median test duration was 14 min. The mean stimulus amplitude was 80 dB peSPL in the left ear and 81 dB peSPL in the right ear, noise levels within the external meatus during sampling were 44 dB SPL on the right ear and 43 dB SPL on the left one, noise contained within the response (A-B difference) was 8.65 dB SPL in the left ear and 8.74 dB SPL in the right ear, mean TEOAEs amplitudes were 21.49 dB SPL and 21.78 dB SPL in the right and left ear respectively, the mean lower and upper limit of the spectrum being 678 and 5720 Hz. According to these criteria 494/640 ears (77.2%) passed the test at the first recording, while TEOAEs resulted to be absent in 146/640 ears (22.8%). A retest was performed successfully before the discharge from the Hospital in 30/640 ears (4.7%). An ABR recording within the third month of life was scheduled as out-patient in the 58 new-borns (116 ears, 18.2%) who failed the test. 18 of them (36 ears, 5.6%) did not complete the program, 19 new-borns (38 ears, 11.8%) showed a normal ABR, while two new-borns (four ears, 0.6%) failed ABR after 3 months. A second ABR performed after 6 months was normal. Conclusions: TEOAEs recording seems at now the test of choice for a universal hearing screening. However, a greater standardization of criteria both in performing the test and in evaluating the results is needed.

Gangguan pendengaran pada masa bayi akan menyebabkan gangguan wicara, berbahasa, kognitif, masalah sosial, dan emosional. Identifikasi gangguan pendengaran secara dini dan intervensi yang sesuai sebelum usia 6 bulan terbukti dapat mencegah segala konsekuensi tersebut. The Joint Committee on Infant Hearing tahun 1994 merekomendasikan skrining pendengaran neonatus harus dilakukan sebelum usia 3 bulan dan intervensi telah diberikan sebelum usia 6 bulan. Otoacoustic emissions (OAE) dan/ atau automated auditory brainstem response (AABR) direkomendasikan sebagai metode skrining pendengaran pada neonatus. Pemeriksaan ABR telah dikenal luas untuk menilai fungsi nervus auditorius, batang otak, dan korteks pendengaran. Pemeriksaan OAE sebagai penemuan baru dilaporkan dapat menilai fungsi koklea, bersifat non invasif, mudah dan cepat mengerjakannya, serta tidak mahal. Kata kunci : newborn hearing screening, otoacoustic emissions, auditory brainstem responseP eriode kritis perkembangan pendengaran dan berbicara dimulai dalam 6 bulan pertama kehidupan dan terus berlanjut sampai usia 2 tahun.1 Beberapa faktor risiko pada neonatus perlu diketahui untuk mengindentifikasi kemungkinan adanya gangguan pendengaran kongenital atau didapat bayi dengan gangguan pendengaran bilateral yang diintervensi sebelum usia 6 bulan, pada usia 3 tahun akan mempunyai kemampuan berbahasa normal dibandingkan dengan bayi yang baru diintervensi setelah usia 6 bulan.2-4 Tujuan tulisan ini untuk membahas pentingnya skrining gangguan pendengaran pada neonatus dengan ulasan beberapa cara skrining.
