Origin of the Sound Components During Pharyngeal Swallowing in Normal Subjects

Abstract: The aim of this study was to identify the origin of swallowing sound components by using modern techniques that can provide numeric, synchronized acoustic-radiologic data. We enrolled 15 volunteer subjects (10 men and 5 women, average age = 29.5 +/- 8 years) and used an X-ray camera connected to a video acquisition card to obtain synchronized acoustic-radiologic data (25 images/s). The subjects were asked to swallow 10 ml of a barium suspension. Each sound component was associated with a specific position of t… Show more

“…The second sound was associated to upper esophageal sphincter opening, with the bolus transit through this sphincter, present in all swallows and lasting 185± 103ms. And the third sound corresponded to the structures return to the resting posture, the bolus in the esophagus, lasting 72± 38ms 26. The findings of this study are in accordance with those of a previous study, which also described three sound components as constituting the swallowing sound, related respectively to laryngeal elevation and the bolus passing through the pharynx, the cricopharyngeal opening and the laryngeal descent 25 .…”

“…Thus, it is evident an increasing number of studies with the purpose of studying the swallowing sounds and its correspondence with other physiological events in healthy subjects 9,11,[25][26][27] . The latter, relating the cervical auscultation findings with other assessment methods.…”

“…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) .…”

“…Furthermore, the duration of swallowing apnea (airway closure during swallowing) is known to increase with age [42]. Prolonged apnea may contribute to longer overall swallowing signal duration, particularly if mechanical events associated with airway protection constitute the source of swallowing vibrations [43].…”
