ABSTRACT

RESUMO Objetivo Identificar as definições fisiopatológicas adotadas pelos estudos que investigaram a "sinaptopatia coclear" (SC) e "perda auditiva oculta" (PAO). Estratégia de pesquisa Utilizou-se a combinação de unitermos "Auditory Synaptopathy" or "Neuronal Synaptopathy" or "Hidden Hearing Loss" com "etiology" or "causality" or "diagnosis" nas bases de dados EMBASE, Pubmed (MEDLINE), CINAHL (EBSCO) e Web of Science. Critérios de seleção Incluiu-se estudos que investigaram a SC ou PAO em humanos com procedimentos comportamentais e/ou eletrofisiológicos. Análise dos dados Realizou-se a análise e extração de dados quanto a terminologia, definição e população estudada. Resultados Foram incluídos 49 artigos. Destes, 61,2% utilizaram a terminologia SC, 34,7% ambos os termos e 4,1% utilizaram PAO. As condições mais estudadas foram exposição ao ruído e zumbido. Conclusão A terminologia SC foi empregada na maioria dos estudos, com referência ao processo fisiopatológico de desaferenciação entre as fibras do nervo coclear e as células ciliadas internas


ABSTRACT Purpose To identify the pathophysiological definitions adopted by studies investigating "cochlear synaptopathy" (CS) and "hidden hearing loss" (HHL). Research strategies The combination of keywords "Auditory Synaptopathy" or "Neuronal Synaptopathy" or "Hidden Hearing Loss" with "etiology" or "causality" or "diagnosis" was used in the databases EMBASE, Pubmed (MEDLINE), CINAHL (EBSCO), and Web of Science. Selection criteria Studies that investigated CS or HHL in humans using behavioral and/or electrophysiological procedures were included. Data analysis Data analysis and extraction were performed with regard to terminology, definitions, and population. Results 49 articles were included. Of these, 61.2% used the CS terminology, 34.7% used both terms, and 4.1% used HHL. The most-studied conditions were exposure to noise and tinnitus. Conclusion CS terminology was used in most studies, referring to the pathophysiological process of deafferentiation between the cochlear nerve fibers and inner hair cells.
