Abstract

Purpose: to compare the Auditory Middle Latency Response in adults, one group with and another group without altered auditory skills. In addition, the aim was to compare cut-off values of 30% and 50% for the Ear Effect in terms of sensitivity and specificity.

Methods: the sample comprised 32 individuals of both genders with no hearing loss who were divided into Group 1 (16 individuals with no alterations in auditory skills) and Group 2 (16 individuals with alterations in auditory skills). All participants received an audiological evaluation and measurement of Brainstem and Auditory Middle Latency Potentials.

Results: when Group 1 and Group 2 were compared, a statistically significant difference was only observed in Na and Pa amplitude of waves A1C3 and A2C3. In the analysis of sensitivity and specificity of the Auditory Middle Latency Response, a cut-off value of 50% gave a better balance between sensitivity and specificity.

Conclusion: adults presented with altered auditory abilities had smaller response amplitudes in the Na and Pa components of the waves generated in the left hemisphere. A cut-off value of 50% gave a better discrimination of the Ear Effect for identifying subjects with altered auditory skills.

Resumo

Objetivo: comparar a latência e a amplitude dos componentes Na, Pa, Nb e Pb do Potencial Evocado Auditivo de Média Latência em adultos com e sem alterações em habilidades auditivas, bem como analisar a sensibilidade e a especificidade dos valores de corte de 30% e 50% para o Efeito de Orelha.

Métodos: compuseram a amostra 32 indivíduos de ambos os sexos e sem perda auditiva, sendo subdivididos em Grupo 1 (16 indivíduos sem alterações em habilidades auditivas) e Grupo 2 (16 indivíduos com alterações em habilidades auditivas). Todos os participantes foram submetidos a uma avaliação audiológica e aos Potenciais Evocados Auditivos de Tronco Encefálico de Média Latência. O teste ANOVA foi utilizado na análise dos dados, considerando significantes os valores de p menores ou iguais a 0,05.

Resultados: foi observada diferença estatisticamente significante apenas na amplitude de Na e Pa, quando Grupo 1 e Grupo 2 foram comparados. Esta diferença foi observada nas ondas A1C3 e A2C3. Na análise de sensibilidade e especificidade do Potencial Evocado Auditivo de Média Latência, observou-se que o valor de corte de 50% apresentou um melhor equilíbrio entre os critérios de sensibilidade e especificidade.

Conclusão: os indivíduos adultos com alterações nas habilidades auditivas apresentaram menor amplitude de resposta nos componentes Na e Pa das ondas geradas no hemisfério esquerdo. O valor de corte de 50% apresentou um melhor equilíbrio na análise do Efeito de Orelha para a contribuição no diagnóstico de alterações de habilidades auditivas.
