Correlation of the findings of auditory steady-state evoked potential and of behavioral hearing assessment in infants with sensorineural hearing loss.

PURPOSE: To correlate the findings of an open-field audiometry with the thresholds of steady-state auditory-evoked potentials (SSAEPs) found in infants of up to 6 months of age with sensorineural hearing loss. METHODS: This study included 19 infants with sensorineural hearing loss (8 males and 11 females), with minimum age of 2 months and maximum age of 6 months. The SSAEPs were assessed at 500 and 2000 Hz, and the audiometry was performed in open field through observation of behavioral responses to sound stimuli, at the same frequencies. RESULTS: We observed a significant correlation between the findings of both tests conducted at 500 and 2000 Hz, with p-values of 0.002 and 0.013, respectively. There was no statistical difference between ears (p=0.532) and genders (p=0.615). CONCLUSION: We conclude that there was a significant correlation between the SSAEP thresholds and the findings of the open-field audiometry. Therefore, we can affirm that the SSAEPs are a viable examination, able to predict the degree and configuration of hearing loss in infants of up to 6 months of age, and that they can be included in the clinical routine of hearing assessments conducted in children.

OBJETIVO: Correlacionar os achados da audiometria infantil em campo livre com os limiares do Potencial Evocado Auditivo de Estado Estável (PEAEE) encontrados em lactentes de até 6 meses de idade com perda auditiva sensorioneural. MÉTODOS: Foram incluídos no estudo 19 lactentes, oito do gênero masculino e 11 do feminino, com idade mínima de 2 e máxima de 6 meses, que apresentaram perda auditiva sensorioneural. Foi realizada a pesquisa do PEAEE nas frequências de 500 e 2.000 Hz e realizada a audiometria em campo livre por meio da observação das respostas comportamentais frente a estímulos sonoros, nas mesmas frequências. RESULTADOS: Observamos correlação significativa entre os achados das duas testagens nas frequências de 500 e 2.000 Hz, sendo os valores de p=0,002 e p=0,013, respectivamente. Não houve diferença estatística entre orelhas (p=0,532) e gêneros (p=0,615). CONCLUSÃO: Concluímos que há correlação significativa entre os limiares do PEAEE e os achados obtidos na audiometria infantil em campo livre. Sendo assim, podemos afirmar que o PEAEE é um exame viável, capaz de predizer o grau e a configuração da perda auditiva em lactentes menores de 6 meses, podendo ser incluído na rotina clínica da avaliação audiológica infantil. .
