Abstract
in English, Portuguese

This study aimed to investigate international scientific papers published on the subject of cervical auscultation and its use in speech therapy. The study involved a qualitative review of the literature spanning the last 10 years. Articles were selected from the PubMed database using the following keywords: cervical auscultation, swallowing and swallowing disorders. Research was included that was conducted on adult humans (over 18 years of age) and was written in English. Each citation retrieved from the database was analyzed independently by each of the study researchers to ascertain its relevance for inclusion in the study. The methodology involved formulating the research question, locating and selecting studies and critically evaluating the articles according to the precepts of the Cochrane Handbook. As a result, 35 studies were identified; 13 articles were analyzed because they allowed access to the full text and were related directly to the subject. We found that the studies were performed with groups of healthy subjects and subjects with different types of base pathology. Some studies compared the patterns found in the different groups. Some of the research sought to study the pattern of swallowing sounds with different factors - evaluator experience, the specificity and sensitivity of the method and how to improve the technique of cervical auscultation through the use of instruments other than the stethoscope. The conclusion of this critical analysis is that cervical auscultation is an important tool to be used in conjunction with other assessment methods in the routine clinical evaluation of swallowing.

Este estudo objetivou pesquisar artigos científicos internacionais publicados sobre a ausculta cervical e sua utilização na prática fonoaudiológica. Trata-se de estudo de revisão qualitativa da literatura, envolvendo os últimos 10 anos. Os artigos foram selecionados da base de dados PubMed, utilizando os descritores: auscultation cervical, deglutition e deglutition disorders. A pesquisa deveria ter sido realizada com seres humanos, adultos (maiores que 18 anos) e escrita no idioma inglês. Cada citação recuperada no banco de dados foi analisada independentemente pelos pesquisadores do estudo, visando à pertinência de sua seleção e de sua inclusão ou não no estudo. A metodologia empregada envolveu a formulação da pergunta, a localização e seleção dos estudos, e a avaliação crítica dos artigos, conforme os preceitos do Cochrane Handbook. Como resultados, foram identificados 35 estudos, dos quais 13 foram analisados, pois permitiram acesso ao texto completo e relacionavam-se diretamente ao tema. Concluiu-se que os estudos foram realizados com grupos de sujeitos saudáveis e sujeitos com diferentes tipos de patologia de base. Alguns estudos compararam os padrões encontrados nos diferentes grupos. Constatou-se que parte dos artigos buscou estudar o padrão dos sons da deglutição, com diferentes interfaces: a experiência dos avaliadores; especificidade e sensibilidade do método; e como aprimorar a técnica da ausculta cervical por meio da utilização de outros instrumentos, diferentes do estetoscópio. Com essa análise crítica, concluiu-se que utilização da ausculta cervical é importante como um instrumento utilizado juntamente de outros, na rotina da avaliação clínica da deglutição.
