Abstract

Introduction: In times of COVID-19, gargling disinfectant is commonly used. Disinfectant solutions seem to decrease the infection's symptoms. For disinfection, several techniques are reported. So far, there are no data about the regions in the upper airways achieved by gargled fluid.

Methods: Ten healthy volunteers without any dysphagia were investigated with a high-sensitivity flexible endoscopic evaluation of swallowing (hsFEES®) during and after gargling colored water. One volunteer repeated the gargling process in fast and real-time MRI.

Results: In all cases, no color accumulation was detected on the posterior pharyngeal wall, epi- or hypopharynx during gargling. The MRI scans confirmed the results.

Conclusions: hsFEES® and fast MRI provide an insight into the gargling pattern. Data show that during gargling, the fluid covers the soft tissue in the oral cavity and the anterior part of the soft palate, but not the posterior pharyngeal wall nor the epi- and hypopharynx.

漱口时的消毒液会到达咽部吗？

介绍：在感染 COVID-19 时，通常使用消毒液漱口。消毒液似乎可以减轻感染症状。据报道，有多种消毒技术。到目前为止，还没有关于漱口液对上呼吸道区域作用的数据：方法：十名无任何吞咽困难的健康志愿者在漱口时和漱口后接受了高灵敏度柔性内窥镜吞咽评估（hsFEES®）。一名志愿者在快速实时核磁共振成像中重复了漱口过程：结果：在所有病例中，漱口时均未在咽后壁、会厌或下咽部发现颜色积聚。结论：通过 hsFEES® 和快速核磁共振成像可了解漱口模式。数据显示，在漱口时，液体覆盖了口腔软组织和软腭前部，但没有覆盖咽后壁、会厌和下咽。

期刊介绍： Published since 1947, ''Folia Phoniatrica et Logopaedica'' provides a forum for international research on the anatomy, physiology, and pathology of structures of the speech, language, and hearing mechanisms. Original papers published in this journal report new findings on basic function, assessment, management, and test development in communication sciences and disorders, as well as experiments designed to test specific theories of speech, language, and hearing function. Review papers of high quality are also welcomed.
