Abstract: purpose: to assess the results found in immittance measurements using 226 hz and 1000 hz in neonates without hearing loss risks indicators (hlri) and to correlate them to transient evoked otoacoustic emissions (toaes) and also to study acoustic reflex using 226 hz probe tones. methods: assessments of 52 full - term neonates, being 26 males and 26 females on an age group from 11 to 51 days of life. anamnesis, meatoscopy, eoat, tympanometry using 226 and 1000 probe tones and ipsilateral acoustic reflex research were performed. for statistical analysis of the data the following tests were applied: wilcoxon test and mcnemar, mann-whitney test, test qui-square and kruskal-wallis anova. results: data were analyzed regardless gender and ears. in relation to toaes, (78.8%) were found. the found tympanometric curves using 226 hz probe tone were: a (55.8%), d (40.4%) and ar (1%), b (2.9%); and the found ones using 1000 hz probe tone were: a (74%), d (1%), b (14,4%) and blocked (10.6%). according to p - value, there was a relation between tympanometric and general reproductivity. on the sample, 81.7% of the ears indicated presence of acoustic reflex. conclusion: tympanometric curve using 1000 hz probe tone showed to be more adequate for detecting changes in the middle ear than 226 hz probe tone, changes in the middle ear had influence on amplitude by frequency band and general reproductivity of toaes. acoustic reflex using 226 hz probe tone was present in most of the neonates without hlri.

Abstract: OBJETIVO: analisar os resultados encontrados na imitanciometria com tons de sonda de 226 e 1.000Hz em lactentes sem indicadores de risco para perda auditiva (IRPA) e correlacioná-los com as Emiss es Otoacústicas Transitórias (EOAT). Além de estudar o reflexo acústico ipsilateral com tom de sonda de 226 Hz. MéTODOS: foram avaliados 52 lactentes a termo, 26 do sexo masculino e 26 do feminino, com faixa etária de 11 a 51 dias de vida. Foram realizadas anamnese, meatoscopia, EOAT, timpanometria com tons de sonda de 226 e 1000 Hz e pesquisa do reflexo acústico ipsilateral. Na análise estatística dos dados aplicou-se: teste de Wilcoxon pareado e McNemar, testes de Mann-Whitney, qui-quadrado (ou exato de Fisher) e teste ANOVA por Kruskal-Wallis. RESULTADOS: os dados foram analisados independentes de sexo e orelha. Em rela o à EOAT, 78,8% estavam presentes. As curvas timpanométricas encontradas com tom de sonda de 226 Hz foram: A (55,8%), D (40,4%), Ar (1,0%), B (2,9%); já com tom de sonda de 1000 Hz encontrou-se: A (74%), D(1%), B (14,4%) e Bloqueada (10,6%). O reflexo acústico ipsilateral mostrou-se presente em 81,7% das orelhas. CONCLUS O: houve rela o estatisticamente significante entre as curvas timpanométricas (para os tons de sonda de 226 e 1000 Hz) e a rela o sinal / ruído e a reprodutibilidade geral das EOAT. O reflexo acústico ipsilateral com tom de sonda de 226 Hz esteve presente na maioria dos lactentes sem IRPA.

RESULTS: data were analyzed regardless gender and ears. In relation to TOAEs, (78.8%) were found.

Abstract: hearing is one of the main ways with which one person can contact the external world; it plays a key role in their integration with society. aim: the objective of this study was to analyze the results of the hearing, medical and genetic evaluation of high-risk infants who failed the newborn hearing screening. materials and methods: clinical and experimental study. we assessed thirty-eight neonates, with ages between one and six months. the infants underwent the following procedures: medical interview; immittance testing; brainstem auditory evoked potential; transient evoked otoacoustic emission and otorhinolaryngological evaluation. dna extraction from the oral mucosa was performed for genetic studies using the protocol method adapted from the human genetics lab of the cbmeg/unicamp. results: regarding gender and presence of risk factors, significant statistically differences were not found in normal hearing infants and in those with hearing loss. concerning gestational age, term infants were more affected by hearing loss. hearing loss was identified in 58% of the sample, conduction hearing loss represented 31.5% (12/38) and neurossensory 28.9% of cases. there were none of the genetic mutations most commonly seen in cases with a genetic etiology. conclusion: hearing loss was identified in the majority of high-risk infants.
