Dynamic videofluoroscopic swallow studies were performed on 60 normal adult volunteers to establish normative data for displacement of upper aerodigestive tract structures during deglutition. Variables evaluated included hyoid bone displacement, larynx-to-hyoid bone approximation, pharyngeal constriction, and the extent of pharyngoesophageal sphincter (PES) opening during liquid swallows of 1, 3, and 20 cc. Results showed direct relationships between bolus size and hyoid displacement, between bolus size and PES opening, and between bolus size and pharyngeal constriction. Only hyoid-to-larynx approximation remained unchanged across bolus sizes. Sex differences were noted for all variables except PES opening. Reliability for most measurement variables was excellent. To our knowledge, normative data for pharyngeal constriction and larynx-to-hyoid approximation have not previously been described.
对60名正常成年志愿者进行了动态视频荧光吞咽研究，以建立吞咽过程中上消化道结构位移的标准数据。评估的变量包括舌骨位移、喉与舌骨的接近程度、咽收缩以及在吞咽1毫升、3毫升和20毫升液体时咽食管括约肌（PES）的开放程度。结果显示，食团大小与舌骨位移、食团大小与PES开放以及食团大小与咽收缩之间存在直接关系。只有舌骨与喉的接近程度在不同食团大小之间保持不变。除PES开放外，所有变量均存在性别差异。大多数测量变量的可靠性极佳。据我们所知，此前尚未描述过咽收缩和喉与舌骨接近程度的标准数据。
