PURPOSE: To develop and verify the usability of an internet-based system for telemonitoring and guidance of the hearing aid user as well as monitoring the long-term performance in a pilot group. METHODS: The system "I can hear, but I can't understand" was developed based on recommendations in the literature regarding layout, design, and content for guidance and advice. Three stages were followed: planning, design and content development, and pilot testing. The sample consisted of 43 adults and older adults with any type and degree of hearing loss, who had been regularly using a hearing aid for at least 30 days and at most 24 months, with reading skills and no evidence of cognitive impairments. The individuals were followed up for 8 to 12 months. The users' performance was monitored with the Speech, Spatial and Qualities of Hearing Scale. The usability of this material was assessed with the System Usability Scale. RESULTS: Improved performance and increased self-reported daily use of the hearing aid were observed after the period of guidance and telemonitoring via the system for all research participants. In all analyzes of the SUS scale, it was possible to observe a performance superior to 70 points, demonstrating good usability of the system. In the analysis of the performance of the SSQ, in the three moments of the research, a positive response was observed in all domains, thus showing progress in the use of hearing aids, with significant data for the domain of Hearing Speech. CONCLUSION: The system "I can hear, but I can't understand" proved to be an easy-to-use and effective tool to telemonitor hearing aid users.

Adesão e continuidade ao uso de aparelho de amplificação sonora individual: revisão de escopo / Adherence and continuity to the use of hearing aid: scope review

RESUMO Objetivo identificar os motivos que levam o indivíduo a seguir ou não a recomendação da necessidade do uso do aparelho de amplificação sonora individual (AASI) e a utilização desse dispositivo ao longo dos anos. Estratégia de pesquisa orientações do Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) foram seguidas. As bases de dados pesquisadas foram: Pubmed, Pubmed Central, Scopus, Embase, Web of Science e Cochrane, utilizando os seguintes descritores: "Hearing Aids", "Patient Compliance" e o indicador booleano AND. Critérios de seleção artigos originais primários com desenhos prospectivos, retrospectivos, observacionais ou experimentais; que levantassem, relatassem, verificassem ou analisassem os motivos de adesão ou não ao uso de AASI, independentemente de ser usuário experiente ou não; realizados com a população jovem, adulta e idosa; com indivíduos com qualquer grau, tipo e configuração de perda auditiva; com adaptações unilaterais ou bilaterais e em português, inglês e espanhol. Resultados incluídos 27 estudos na análise. Verificaram-se duas situações distintas no processo de reabilitação auditiva: aceitação à indicação do uso do AASI e a continuidade do uso do dispositivo de maneira efetiva. Os aspectos que auxiliaram positivamente, negativamente ou não interferiram nessas duas fases foram compilados e apresentados. Conclusão os fatores de maior relevância para a não aquisição do AASI são: percepção de baixo custo-benefício, falta de entendimento da real necessidade e dificuldade de aceitação do uso, enquanto que os que mais impactam na continuidade do uso são: qualidade sonora do AASI, dificuldades de manuseio e percepção de pouco benefício.

ABSTRACT Purpose To identify the reasons that lead the individual to follow or not the recommendation to use the hearing aid and its use over the years. Research strategy Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) recommendations were followed. The databases searched were: Pubmed, Pubmed Central, Scopus, Embase, Web of science and Cochrane, using the following descriptors: "Hearing Aids", "Patient Compliance" and the Boolean indicator AND. Selection criteria primary original articles with prospective, retrospective, observational or experimental designs; that raise, report, verify or analyze the reasons for adherence or not to the use of hearing aids, regardless of being an experienced user or not; carried out with the young, adult and elderly population; with individuals with any degree, type and configuration of hearing loss; with unilateral or bilateral adaptations and in Portuguese, English and Spanish. Results 27 studies were included in the analysis. There were two distinct situations in the auditory rehabilitation process: acceptance of the indication of the use of HA and the continuity of the effective use. Thus, the aspects that positively, negatively or do not interfere in these two phases were compiled and presented. Conclusion the most relevant factors in the non-adherence to HA were: perception of low cost-benefit, lack of understanding of the real need and difficulty in accepting its use; while the ones that most impacted the continuity of use were: HA sound quality, handling difficulties and perception of little benefit.

Wideband Acoustic Absorbance in Otosclerosis: Does Stapedotomy Restore Normal Tympanic Cavity Function?

Abstract Introduction Otosclerosis is characterized by the fixation of the stapes to the oval window, thereby impairing acoustic signal absorbance. A commonly used surgical technique for improving hearing in cases of otosclerosis is stapedotomy. However, it is unclear whether this surgery restores all the physical characteristics of the tympano-ossicular system. Objective To evaluate the tympano-ossicular system in individuals with fenestral otosclerosis pre and poststapedotomy using wideband tympanometry. Method A total of 47 individuals and 71 ears were assessed. The subjects were divided into three groups: presurgery otosclerosis; postsurgery; and a control group of normal-hearing adults. A handheld tympanometer with a wideband module (226-8,000 Hz) was used to take measurements at ambient pressure and under pressurized conditions. The level of statistical significance adopted was p ≤ 0.05. Results Acoustic absorbance at 226 Hz was low for all groups. At frequencies in the range 630 to 5,040 Hz, each group had a characteristic absorbance curve, allowing them to be distinguished from one another. In the presurgery group, absorbance values were below normal levels, with energy absorbance below 10%. Low energy absorbance was most evident at 1,000 Hz in the presurgery group, but this was not observed in the postsurgery group. Although there was an improvement in hearing, the surgery failed to restore the tympano-ossicular system to normal. Conclusion Wideband acoustic absorbance proved able to differentiate normal ears and otosclerotic ears pre and postsurgery, under both ambient pressure and pressurized conditions.

Analysis of wideband tympanometry in Ménière's disease / Análise da timpanometria de banda larga na doença de Ménière

Abstract Introduction: Endolymphatic hydrops is the pathophysiological substrate of Ménière's disease. The changes in the inner ear, transmitted to the middle ear through changes in the ossicular chain mobility, can be quantified by wideband tympanometry, through the measurement of the acoustic absorbance at multiple frequencies, represented by the sound energy absorbed by the middle ear, even at its early stages. Studying the behavior of the middle ear through the absorbance in patients with endolymphatic hydrops under ambient pressure and under peak pressure can be useful for detecting Ménière's disease. Objective: To characterize acoustic absorbance behavior in subjects with symptomatic and asymptomatic Ménière's disease compared to controls, in order to verify the ability of wideband tympanometry to detect Ménière's disease. Methods: We carried out a cross-sectional study with a diagnostic approach comparing the findings of wideband tympanometry at ambient pressure and peak pressure between the ears of the control group (n = 30), the asymptomatic group (n = 21) and the symptomatic group (n = 9). Results: Different peak pressure values were found between the ears of the control group (0daPa), the asymptomatic group (−11 daPa) and the symptomatic group (−192 daPa), with p < 0.05 by the Kruskal-Wallis test, Mann Whitney test and Bonferroni correction. Different absorbance values were found between the ears of the symptomatic group and the asymptomatic group compared to the control group for low frequencies at ambient pressure and peak pressure, with p < 0.05 by the Kruskal-Wallis test, Mann Whitney test and Bonferroni correction. Conclusions: The Wideband Tympanometry test was capable of identifying the presence of Ménières disease, and to differentiate between asymptomatic and symptomatic patients, when comparing them with healthy individuals.

Resumo Introdução: A hidropsia endolinfática é o substrato fisiopatológico da doença de Ménière. As alterações desencadeadas na orelha interna, transmitidas à orelha média pelas modificações na mobilidade da cadeia ossicular, podem ser quantificadas pela timpanometria de banda larga, através da medida da absorvância acústica sob múltiplas frequências, representadas pela energia sonora absorvida pela orelha média, mesmo em estágios iniciais de sua instalação. Estudar o comportamento da orelha média através da absorvância em pacientes com hidropisia endolinfática sob pressão ambiente e sob o pico de pressão pode ser útil na detecção da doença de Ménière. Objetivo: Caracterizar o comportamento da absorvância em indivíduos com diagnóstico da doença de Ménière sintomáticos e assintomáticos, comparados com controles, a fim de verificar a capacidade da timpanometria de banda larga em detectar variações clínicas relacionadas a possível hidropisia endolinfática. Método: Foi realizado um estudo transversal, com enfoque diagnóstico, que comparou os achados da timpanometria de banda larga na pressão ambiente e no pico de pressão entre orelhas do grupo controle (n = 30), grupo assintomático (n = 21) e grupo sintomático (n = 9). Resultados: Foram encontrados valores do pico de pressão diferentes entre orelhas do grupo controle (0 daPa), do grupo assintomático (-11 daPa) e do grupo sintomático (-192 daPa), com p <0,05 pelos testes de Kruskal-Wallis, Mann Whitney e correção de Bonferroni. Foram encontrados valores de absorvância diferentes entre orelhas do grupo sintomático e do grupo assintomático em relação ao grupo controle para as frequências baixas na pressão ambiente e na pressão de pico, com p < 0,05 pelos testes de Kruskal-Wallis, Mann Whitney e correção de Bonferroni. Conclusão: A timpanometria de banda larga foi um teste capaz de identificar a presença da doença de Ménière e de diferenciar os pacientes assintomáticos e sintomáticos, comparando-os com indivíduos hígidos.

Correspondência entre alvo e saída da prótese auditiva segundo as regras prescritivas NAL-NL1 e NAL-NL2 / Correspondência entre alvo e saída da prótese auditiva segundo as regras prescritivas NAL-NL1 e NAL-NL2

RESUMO Objetivo Analisar comparativamente os alvos prescritos pelas regras NAL (National Acoustic Laboratories) não lineares com a resposta da prótese auditiva obtida por meio das mensurações com microfone-sonda no ajuste de uso efetivo, de acordo com o grau da perda auditiva. Método Participaram do estudo 67 usuários experientes de próteses auditivas. Todos foram reavaliados quando compareceram às sessões de acompanhamento periódico. Nesse momento, realizou-se avaliação audiológica, registrando-se as horas de uso do dispositivo e realizando-se a resposta com prótese auditiva (REAR - Real Ear Aided Response). Resultados Observou-se que 80% das próteses auditivas de todos os grupos atingiram a faixa analisada, com exceção do grupo de perda moderada. Também foi realizada a análise da porcentagem de orelhas cuja resposta com prótese auditiva estivesse em ±5 dB para as frequências baixas e ±8 dB nas altas frequências e observou-se que menos de 80% dos ajustes atingiram esta faixa. Intervalos de confiança foram construídos para verificar a faixa de adaptação de preferência dos usuários experientes. Conclusão A faixa de ±10 dB demonstra ser a de preferência dos usuários. Porém, para usuários experientes, sugere-se que a faixa de adaptação encontre-se na faixa de ±3 nas frequências baixas e médias e ±7 na região de altas frequências.

ABSTRACT Purpose To compare the targets prescribed by the non-linear NAL with the real ear aided response - REAR obtained through probe microphone in the setting of effective use according to the degree of hearing loss. Methods 67 experienced hearing aid users participated in the study. All were reassessed when attending follow-up sessions. At that moment, they were asked whether they had any complaints with respect to the amplification. An audiological evaluation was performed, the hours of use of the device were recorded and the new probe microphone measurement was taken. Results The percentage of ears with REAR within ± 10dB of the prescriptive target was verified. It was observed that 80% of the hearing aids of all groups reached the analyzed range, with the exception of the moderate hearing loss group. We also performed the analysis of the percentage of ears whose hearing aid response was within ± 5 dB for the low frequencies and ± 8 dB for the high frequencies, and it was observed that less than 80% of the adjustments reached this range. Confidence intervals were constructed to verify the preference fit to target of experienced users. Conclusion The range of ±10dB proves to be the users' preference. For experienced users, it is suggested that the adaptation phase be found in the range of ±3 in the low and medium frequencies and ±7 in the high frequency region

Aparelhos de amplificação sonora individual: quais são as queixas mais recorrentes dos usuários e suas possíveis relações com ajustes finos? / Hearing aids: what are the most recurrent complaints from users and their possible relationship with fine tuning?

RESUMO Objetivo identificar as queixas mais recorrentes dos usuários de aparelhos de amplificação sonora individual (AASI) e estabelecer possíveis relações que auxiliem a busca de soluções de problemas no processo de adaptação desses dispositivos. Métodos estudo transversal, descritivo e quantitativo, realizado mediante questionário on-line, respondido por 176 fonoaudiólogos. Após computação e organização das respostas, realizou-se uma codificação e foram descritos 30 termos mais recorrentes, referentes às queixas dos usuários. Foram estabelecidas quatro categorias para verificar cada termo relatado e sua correspondência com o problema apontado em cada questão. Para o direcionamento das possíveis relações entre as queixas e suas resoluções, os termos foram divididos nos seguintes aspectos principais do processo de adaptação de AASI: adaptação física, ajuste das características eletroacústicas e características intrínsecas do usuário. Resultados foram descritos 30 termos representativos das queixas, com maior número de ocorrências para o termo "Aparelho muito alto/Som muito alto", que apareceu 223 vezes. O termo "Não escuta nada" apareceu com menor número de ocorrências, 25 vezes. No total, foram encontradas seis queixas relacionadas a aspectos físicos, 17 a ajustes de características eletroacústicas, quatro que poderiam estar relacionadas a ambos os aspectos e duas a características intrínsecas do indivíduo. Conclusão foi possível elencar as queixas mais referidas pelos usuários de AASI. Observou-se que é viável, a partir de uma queixa, direcionar um suposto aspecto relacionado à adaptação e auxiliar os fonoaudiólogos a levantar soluções, apesar de ser clara a necessidade de um olhar individualizado para cada paciente e situação.

ABSTRACT Purpose To identify the most frequent complaints from hearing-aid users and establish possible relationships that might help audiologists solve some problems. Methods Cross-sectional, descriptive and quantitative study, carried out through an online questionnaire, answered by 176 audiologists. After analyzing the responses and computing the terms, coding was performed and the 30 most frequent complaints were described. Four categories were established to verify each reported term and its correspondence with the problem pointed out in each question. To address the possible relationships between complaints and their solutions, the terms were divided into the following main aspects of the hearing aid fitting process: physical adaptation, adjustment of electroacoustic characteristics and user's intrinsic characteristics. Results 30 representative terms of complaint were described due to their high number of occurrences : the term "very loud device / very loud sound" appeared 223 times whereas the term "I cannot hear anything" had the fewest number of occurrences, 25 appearances. In total, there were six complaints related to physical aspects, 17 to adjustments of electroacoustic characteristics, four that could be related to both aspects and two to intrinsic characteristics of the individual. Conclusion It was possible to identify the most frequently reported complaints of hearing aid users. . It was observed that it is feasible, based on a complaint, to address a supposedly related aspect of adaptation and help audiologists find solutions. However, each particular patient and situation must be given individualized attention.

Cortical auditory-evoked potential as a biomarker of central auditory maturation in term and preterm infants during the first 3 months.

OBJECTIVES: To analyze central auditory maturation in term and preterm infants during the first 3 months of life by comparing the latency and amplitude of cortical auditory-evoked potential at different frequencies. METHODS: In this study, 17 term and 18 preterm infants were examined; all had tested positive on the neonatal hearing screening test. Cortical auditory potential was investigated during the first and third months of life. The response of the cortical auditory-evoked potential was investigated at frequencies of 500, 1000, 2000, and 4000 Hz. The latency and amplitude of the cortical response were automatically detected and manually analyzed by three researchers with experience in electrophysiology. The results were compared using analysis of variance and the Bonferroni test. A significance level of 5% was used for all analyses. RESULTS: Latency values of cortical auditory-evoked potential in the first month of birth were significantly higher than those in the third month, and latency values of the preterm group were higher than those of the term group, regardless of the frequency and time of evaluation. In general, the latency of the cortical auditory-evoked potential was higher at high frequencies. Amplitude values in the third month of life were significantly higher than those in the first month for term and preterm infants. CONCLUSION: Central auditory maturation was observed in both groups but with different results between those born at term and preterm, with latencies of cortical auditory-evoked potential higher for the preterm group and at high frequencies.

Speech, Spatial and Qualities of Hearing Scale in assessing the benefit in hearing aid users. / Speech, Spatial and Qualities of hearing scale na avaliação do benefício em usuários de prótese auditiva.

PURPOSE: To check the degree of reliability of the Speech, Spatial and Qualities of Hearing Scale (SSQ), in the assessment of the benefit in hearing aid users. METHODS: Thirty hearing impaired adults, candidates for use (novice users) or users whose hearing aids (experienced users) were being replaced, participated in the study. All participants underwent complete audiological evaluation, selection and fitting of hearing aids, which included checking measurements with a probe microphone and assessment of the benefit from using hearing aids with the Speech, Spatial and Qualities of Hearing Scale (SSQ) questionnaire. A basic SSQ questionnaire was administered in the form of an interview. Later, four weeks after having started using new hearing aids, the versions B (for novice users) and C (for experienced users) of the SSQ questionnaire were administered. RESULTS: Greater difficulty was identified in the Hearing for speech domain than in the other domains, namely Spatial hearing, and Qualities of hearing. Most participants found all questions easy to understand and reported they were compatible with the situations they dealt with in their daily life. Statistical analysis revealed a high Cronbach's alpha coefficient (>0.9), which is indicative of good internal consistency between the various items contained in the questionnaire. It proved to be a valuable tool for subjectively assessing communicative performance with and without the use of hearing aids. CONCLUSION: The SSQ proved to be an instrument that is easy to administer and highly reliable, allowing for the assessment of the benefit in individuals who are undergoing auditory rehabilitation, and which can be administered to individuals using different types of hearing aids.

Cortical auditory evoked potential in assessment of neonates: a study about minimum level of responses in term and preterm newborns / Potencial evocado auditivo cortical na avaliac¸ão de neonatos: um estudo sobre o nível mínimo de respostas em nascidos a termo e pré-termos

Abstract Introduction: The study of the threshold level of cortical auditory response in adults has been investigated in previous studies. Due to maturational issues, little is known about these responses in neonates. Technological advances with automatic analysis devices now allow investigation in specific populations. Thus, new studies are needed to establish the feasibility of using this auditory potential to identify the lowest levels of responses in children. Objective: Verify and compare latency and amplitude in 80 dBnNA and the minimum level of cortical auditory response in term and preterm neonates. Methods: A cross-sectional, comparative study involving 59 neonates, 35 full-term births and 24 preterm births, with positive results in the Neonatal Hearing Screening. The Hearlab system was used to investigate the P1i auditory potential with tone burst stimulus at frequencies of 500, 1000, 2000 and 4000 Hz. The minimum response level search ranged from 80 to 0 dBNA and was detected automatically. The results were compared between groups, evaluating the latency and amplitude in 80 dBNA and the minimum level of cortical auditory response. Results: The mean values obtained for the minimum level of cortical auditory response in term group were 26 ± 8.81; 26.14 ± 6.97; 29 ± 7.65 and 29.43 ± 7.04 dBNA and for preterm neonates of 31.96 ± 10.41; 34.13 ± 11.34; 33.64 ± 11.03 and 37.73 ± 11.92 dBNA, for the frequencies of 500, 1000, 2000 and 4000 Hz, respectively. There was a difference between groups for the latency of P1i at 4000 Hz and the minimum response levels at 500, 1000 and 4000 Hz, with higher values for preterm infants. Conclusion: It was possible to obtain latency and amplitude values at 80 dBnNA and the minimum level of cortical response in term and preterm newborns, with different results between groups, with higher values in those born preterm.

Resumo Introdução: A investigação do nível mínimo de resposta auditiva cortical tem sido alvo de diferentes estudos em adultos. Devido a questões de maturação, pouco se sabe sobre essas respostas em recém-nascidos. Com o avanço tecnológico, dispositivos de análise automática surgiram com o objetivo de retomar essa avaliação em populações específicas. Assim, novos estudos são necessários para verificar a viabilidade do uso desse potencial auditivo na obtenção de níveis mínimos de respostas na criança. Objetivo: Verificar e comparar latência e amplitude em 80 dBnNA e o nível mínimo de resposta auditiva cortical em recém-nascidos a termo e pré-termo. Método: Estudo transversal, comparativo, envolvendo 59 neonatos, 35 nascidos a termo e 24 pré-termos, com resultados positivos na triagem auditiva neonatal. O sistema Hearlab foi utilizado para investigar o potencial auditivo P1i com estímulo tone burst nas frequências de 500, 1000, 2000 e 4000 Hz. A busca do nível mínimo de resposta variou de 80 a 0 dBNA e foi detectado automaticamente. Os resultados foram comparados entre os grupos, avaliando a latência e amplitude em 80 dBNA e o nível mínimo de resposta auditiva cortical. Resultados: Os valores médios obtidos para o nível mínimo de resposta auditiva cortical no grupo nascido a termo foram 26 ± 8,81; 26,14 ± 6,97; 29 ± 7,65 e 29,43 ± 7,04 dBNA e para recém-nascidos pré-termos foram de 31,96 ± 10,41; 34,13 ± 11,34; 33,64 ± 11,03 e 37,73 ± 11,92 dBNA, para as frequências de 500, 1000, 2000 e 4000 Hz, respectivamente. Houve diferenc¸a entre os grupos para a latência de P1i em 4000 Hz e os níveis mínimos de resposta em 500, 1000 e 4000 Hz, com valores maiores em Pré-termos. Conclusão: Foi possível obter valores de latência e amplitude em 80 dBnNA e o nível mínimo de resposta cortical em recém-nascidos a termo e Pré-termos, com resultados diferentes entre osgrupos, com valores maiores em pré-termos.

Test-Retest Reliability of the Speech, Spatial and Qualities of Hearing Scale (SSQ) in Brazilian Portuguese

Introduction: The Speech, Spatial and Qualities of Hearing Scale (SSQ) is a questionnaire designed to assess the auditory experience and quantify hearing disabilities in realistic communication situations, with particular attention to binaural hearing. Objective: To determine the test-retest reliability of the SSQ in Brazilian Portuguese. Method: A total of 35 individuals with mean age of 61 years and mean education of 7 years were interviewed. The mean auditory threshold was 44.29 dBNA in the best ear and 58.04 dBNA in the worst ear. The SSQ in Portuguese was applied at two time points, test and retest. An interval of 7 to 20 days between interviews was established. The level of significance adopted was 0.05, or 5%. Results: The analysis revealed a high Cronbach α coefficient for the three domains and for the general component of the scale, demonstrating good internal consistency between the items. In addition, a significant strong correlation was detected between test and retest of the SSQ on the analysis by domain and for the general component of the scale. A significant moderate-to-strong correlation between test and retest by question was found, except for question 2 of Part I. Conclusion: The test-retest reliability indicators showed good stability of the Portuguese version of the SSQ, indicating that the scale is suitable for use in the hearing-impaired population in Brazil.

Wideband acoustic absorbance in children with Down syndrome / Absorvância acústica de banda larga em crianças com síndrome de Down

Abstract Introduction: Tympanometry is currently the most frequently used tool for assessing the status of the middle ear, commonly assessed using a single 226 Hz tone. However, the use of the Acoustic Immittance Measures with a wideband stimulus is a promising high-resolution evaluation, especially in individuals known to have middle ear alterations, such as Down syndrome patients. Objective: The aim of this study was to analyze the acoustic absorbance measurements in children with Down syndrome. Methods: Cross-sectional study, approved by the institution's ethics committee. Data were collected from 30 children, with a mean age of 8.4 years, 15 with Down syndrome (DS-study group) and 15 children with typical development and no hearing complaints (control group). Energy absorbance was measured at frequencies of 226-8000 Hz at ambient pressure and at peak pressure as a function of frequency using TITAN equipment. Statistical analysis was performed using the established level of statistical significance of 5%. Results: With the 226 Hz probe tone, 30 ears of the control group and 22 of the study group exhibited Type A tympanograms, whereas Type B was observed in eight children in the study group. The mean acoustic absorbance ratio of the study group was lower than that of the control group at frequencies centered at 2520 Hz (p = 0.008) for those with normal tympanometry results, and 226-4000 Hz (p < 0.03) for those with a Type B tympanometry curve. Conclusion: The low energy absorption in the presence of normal tympanograms in children with Down syndrome may suggest middle ear abnormalities.

Resumo Introdução: A timpanometria é a ferramenta mais usada para avaliar o status da orelha média, comumente avaliada por meio de uma única frequência com o tom de 226 Hz. No entanto, o uso da medida de imitância acústica com estímulo de banda larga é uma avaliação de alta resolução promissora, especialmente em pacientes conhecidos por frequentemente apresentar alterações da orelha média, como na síndrome de Down. Objetivo: Analisar as medidas de absorvância acústica em crianças com síndrome de Down. Método: Estudo transversal, aprovado pelo comitê de ética da instituição. Foram coletados dados de 30 crianças, com idade média de 8,4 anos, sendo 15 com síndrome de Down (SD-grupo de estudo) e 15 crianças desenvolvimento típico e sem queixas auditivas (grupo controle). A absorvância de energia foi medida nas frequências de 226-8.000 Hz à pressão ambiente e no pico de pressão em função da frequência, usou-se o equipamento Titan. A análise estatística foi feita com o nível de significância estatística adotado de 5%. Resultados: Com o tom de sonda de 226 Hz foram observadas 30 orelhas do grupo controle e 22 do grupo estudo com timpanometria Tipo A e o Tipo B foi observado apenas em oito crianças do grupo estudo. A razão média de absorvância acústica do grupo estudo foi menor do que a do controle nas frequências centradas em 2.520 Hz (p = 0,008) para aqueles com resultados timpanométricos normais e de 226-4.000 Hz (p < 0,03) para aqueles com curva timpanométrica Tipo B. Conclusão: A baixa absorção de energia na presença de timpanogramas normais nas crianças com síndrome de Down pode sugerir anormalidades na orelha média.
