Sound Component Duration of Healthy Human Pharyngoesophageal Swallowing: A Gender Comparison Study

Abstract: Cervical auscultation is a noninvasive technique for studying swallowing that was first used in the 1960s. The aim of our study was to use the numeric acoustic recording technique for analyzing swallowing sound signals in healthy subjects while they ingested a defined volume and consistency of a specific substance. Twenty males and ten females were included in the study and given 10 ml of a barium suspension to swallow. A microphone was placed on the skin overlying the lateral border of the trachea, directly u… Show more

“…Medidas específicas da duração das deglutições de 260 indivíduos não-disfágicos com metodologia semelhante àquela utilizada no presente estudo foram realizadas por outro autor que encontrou intervalos entre as explosões (definido como T) próximos aos encontradas neste estudo (1) . Três trabalhos referem durações relativas ao tempo decorrido entre as duas explosões da deglutição menores que as descritas aqui (3,13,14) . Essa diferença pode ser justificada pelas Por outro lado, diversos estudos mostram durações dos sons da deglutição significativamente maiores que os tempos encontrados aqui, variando entre 250 e 800 ms (3,(15)(16)(17)(18) .…”

“…Quanto às medidas absolutas, intervalo entre os picos das duas explosões da deglutição (T) e duração da apneia da deglutição, não houve diferença estatística entre homens e mulheres. Esses achados corroboram os resultados de outros encontrados na literatura recente (13,16,19) . Por outro lado, já foi relatado que a duração dos sons da deglutição de mulheres foi menor que a de homens.…”
