The Videofluorographic Swallowing Study (VFSS) has become the routine method for assessing swallowing dysfunction and accordingly, much research has been conducted on this procedure. However, due to a lack of standardization of the method of analysis of VFSS, it is often difficult to compare the results of such studies. Therefore, we conducted a comparative study of VFSS's spatial measurement using different standard planes used in the past study and Camper's plane and examined which plane was the most preferable.
VFSS was performed on 20 healthy young volunteers (26.9 +/- 3 years) and 9 healthy elderly (77.3 +/- 3 years). Each subject swallowed 4ml of thin liquid barium. We measured hyoid displacement and opening of the upper esophageal sphincter (UES) by using four different standard planes.
In the young group, the correlation between anterior hyoid displacement and UES opening was significant in all standard planes. In the elderly group, the correlation between anterior hyoid displacement and UES opening was significant only in Camper's plane. Moreover, this plane is hard to be affected by morphological change as ageing.
Camper's plane was found to be as the most preferable plane for analyzing swallowing function.
视频荧光吞咽造影检查（VFSS）已成为评估吞咽功能障碍的常规方法，因此针对该检查方法已开展了大量研究。然而，由于VFSS分析方法缺乏标准化，此类研究结果往往难以比较。因此，我们使用过去研究中使用的不同标准平面和坎珀平面，对VFSS的空间测量进行了比较研究，并考察了哪个平面最为适用。
对20名健康年轻志愿者（26.9±3岁）和9名健康老年人（77.3±3岁）进行VFSS检查。每位受试者吞咽4毫升稀钡剂。我们使用四个不同的标准平面测量舌骨位移和食管上括约肌（UES）开口情况。
在年轻组中，所有标准平面下舌骨向前位移与UES开口之间均存在显著相关性。在老年组中，仅在坎珀平面下舌骨向前位移与UES开口之间存在显著相关性。此外，该平面不易受年龄增长导致的形态变化影响。
坎珀平面被认为是分析吞咽功能的最适用平面。
