Objectives :The purpose of this study was to develop an objective evaluation method for swallowing at Chair-Side.Methods :Study 1 : Subjects ; Ten healthy, fully dentate (Mean age : 28.6±3.5yo.)Study 2: Subjects ; Five healthy, fully dentate (Mean age : 30.6±5.9yo.)Study 3 : Subjects ; Five healthy, fully dentate (Mean age : 29.0±2.4yo.)Study 4 : Subjects ; Five healthy, fully dentate (Mean age : 29.5±3.6yo.)Study 5 : Subjects ; Five edentulous patients with complete denture (Mean age : 68.4±7.3yo.)To observe tongue movements in swallowing the test food, general-purpose ultra-sound diagnostic equipment was used with a 5 MHz electronic convex sector scanning probe. To record swallowing sounds, a heart sound microphone was connected to the ultra-sound diagnostic equipment through a physiologic signal unit. The tongue movements and swallowing sounds were simultaneously recorded on recording paper and analyzed by plotting five inflection points (T1, T2, T3, T4 and T5) of the movement curve and two beginning points of swallowing sounds (S1 and S2) using a digitizer. Subjects were directed to swallow the test food (a starch compound mixed with water)Results :Study 1 : It was confirmed that all the data of 10 subjects had repeatability. There was statistically significant correlation between T4 and S1. S1 were always ahead of T4.Study 2 : From the VF-image, it was confirmed that S1 coincided with the point of time that the epiglottis was just going to shut, and T4 coincided with the point of time that the tail of test food has just got to the esophagus.Study 3 : Thickness of palatal plate and biteplate influence on swallowing function.Study 4 : The body positions influence on swallowing function.Study 5 : Denture insertion was effective for swallowing function.Conclusion :From this investigation, it is suggested that our evaluating method could be useful for the diagnosis of swallowing at chair-side.

目的：本研究的目的是发展一种客观的评价方法，吞咽在Chair-Side.Methods：研究1：受试者; 10名健康，完全齿状（平均年龄：28.6± 3.5岁）。研究2：受试者;五名健康、牙齿完整（平均年龄：30.6± 5.9岁。）研究3：受试者; 5名健康、完全有齿（平均年龄：29.0± 2.4岁）。研究4：受试者; 5名健康、完全有齿（平均年龄：29.5± 3.6岁）。研究5：受试者; 5名全口义齿无牙患者（平均年龄：68.4± 7.3岁）。为了观察吞咽测试食物时的舌头运动，使用具有5 MHz电子凸扇形扫描探头的通用超声诊断设备。为了记录吞咽音，通过生理信号单元将心音麦克风连接到超声诊断设备。在记录纸上同时记录舌运动和吞咽音，并通过使用数字化仪绘制运动曲线的五个拐点（T1、T2、T3、T4和T5）和吞咽音的两个起始点（S1和S2）来分析。受试者被指示吞咽测试食物（与水混合的淀粉化合物）结果：研究1：证实10名受试者的所有数据具有重复性。T4和S1之间存在统计学显著相关性。研究2：从VF图像上证实，S1与会厌即将关闭的时间点相吻合，T4与试验食物尾部到达食管的时间点相吻合。研究3：腭板和咬合板厚度对吞咽功能的影响。研究4：腭板和咬合板厚度对吞咽功能的影响。结论：本研究所建立的吞咽功能评价方法对椅旁吞咽障碍的诊断有一定的参考价值。
