Abstract
This study aimed to investigate on the literature the utility of Auditory middle latency response in children focusing on the study of the auditory system on its normal and deviant processes. The integrative review of the scientific literature consisted in the search for studies using databases such as PubMed, Scopus, and Scielo. The descriptors used for the search were: "auditory middle latency response" "auditory middle latency potential", and "children" "child", "childhood", "maturation", "development". Selection criteria: The studies were complete papers, which participants were children submitted to examination of the AMRL. The individually analysis of the studies verified the aspects related to the purpose of the research, the applied methodology, and the conclusion of each study. Were selected a total of 21 articles, among them eleven studies from PubMed, eight studies from Scopus, and two studies from Scielo. Of the total 21 articles, six of them were performed with healthy children, four examined the components of this potential in children with language disorders or specific language disorder, four studies assessed children with cochlear implants and seven children with other changes. This integrative review showed the importance of research auditory middle latency response in children. Based on this, a more accurate and early diagnosis of patients with alterations language, speech or learning and auditory processing disorders were allowed. Moreover, it was observed the evolution on theraupeutic monitoring.

Resumo
Este estudo teve como objetivo investigar na literatura a utilidade do Potencial evocado auditivo de média latência na população infantil para o estudo do sistema auditivo em seus processos normais e desviantes. A revisão integrativa da literatura científica consistiu na busca de estudos utilizando as bases de dados: PubMed, Scopus e Scielo. Como descritores para a pesquisa foram utilizados os termos: "auditory middle latency response" "auditory middle latency potential", "children", "child", "childhood", "maturation' e "development". Os estudos eram artigos completos, cujos participantes foram crianças, submetidas ao exame de Potencial evocado auditivo de média latência. A análise dos estudos individualmente verificou aspectos relacionados ao objetivo da pesquisa, a metodologia utilizada e a conclusão de cada estudo. Foram selecionados e lidos na íntegra um total de 11 estudos da base bibliográfica PubMed, oito estudos da Scopus e dois estudos da Scielo. Do total de 21 artigos, seis deles foram realizados com crianças saudáveis, quatro examinaram os componentes desse potencial em crianças com distúrbio de linguagem ou distúrbio específico de linguagem, quatro estudos avaliaram crianças usuárias de implante coclear, e sete crianças com outras alterações. Esta revisão integrativa mostrou a importância da investigação dos potenciais evocados auditivos de média latência em crianças. Tal avaliação vem permitindo um diagnóstico mais precoce e preciso de pacientes com alterações de linguagem, fala ou de aprendizado e de distúrbios do processamento auditivo além do monitoramento de evolução terapêutica.
