The purpose of the present study was to observe the lingual and pharyngeal movement at the time of eating and swallowing. Currently many researchers adopt video fluorography (VF) to evaluate this movement and report the swallowing mechanism. Considering the hazards of VF including irradiation, we should restrict frequent prolonged x-ray examinations. In our clinical practice, we can use ultrasonic examination as a non-invasive imaging instead of VF. In the present study we used ultrasound analysis in sagittal plane examination to establish a new method for the simultaneous evaluation of the movement of the posterior tongue surface and the hyoid bone at the time of swallowing. We observed and analyzed the movement of the hyoid bone by using ultrasonic examination for the first year. The reproducible results obtained in our analysis demonstrated that the hyoid bone moved along a certain or bit.In the latter half of the first year, we attempted to develop the echo window which simultaneou … More sly visualized the movement of the posterior tongue surface and the hyoid bone and studied the direction of the probe. The simultaneous visualization of the movement of the posterior tongue surface and the hyoid bone was subject to great individual variations. Therefore we occasionally failed to visualize their movement simultaneously.In the second year, we conducted the following experiment. Because of the lack of the established standards for the evaluation of the swallowing phase, we set the pressure transducer integrated palatal plate in a subject's oral cavity and measured the pressure at the time when the tongue tip was pressed against the anterior part of the palate. Furthermore we measured the peak lingual pressure and used it as a standard to set the time axis. We selected four normal volunteers and analyzed the changes in the movement of the posterior part of tongue when they swallowed two different types of food, honey-like sticky food and gelatinous food. The difference in physical states of food and individual variations seemed to affect the time before and after the achievement of the peak lingual pressure. The tongue movement was evaluated at the time when the peak lingual pressure was achieved. Compared with gelatinous food, honey-like sticky food significantly promoted the forward movement of the posterior tongue surface.In the future we should establish a technique which enables us to simultaneously evaluate the movement of the posterior tongue surface and the hyoid bone in the patients with dysphagia.

本研究的目的是观察进食和吞咽时舌和咽的运动。目前，许多研究者采用视频荧光成像（VF）来评估这种运动并报道其吞咽机制。考虑到VF的危害，包括辐射，我们应该限制频繁的长时间X射线检查。在我们的临床实践中，我们可以使用超声检查作为一种非侵入性的成像，而不是VF。在本研究中，我们使用超声分析矢状面检查，建立一个新的方法，同时评估运动的舌后表面和舌骨在吞咽的时间。术后第一年用超声检查观察分析舌骨的运动情况。在我们的分析中获得的可重复的结果表明，舌骨移动沿着一定或一点点。 ...更多信息 Sly观察舌后表面和舌骨的运动，并研究探针的方向。舌后表面和舌骨运动的同时可视化受到很大的个体差异。因此，我们有时无法同时看到它们的运动。在第二年，我们进行了以下实验。由于吞咽阶段的评价缺乏既定的标准，我们将压力传感器集成腭板设置在受试者的口腔中，并测量舌尖压在腭前部时的压力。此外，我们还测量了舌压峰值，并将其作为设定时间轴的标准。本文选择4名正常志愿者，分析了他们吞咽两种不同类型的食物（蜂蜜状粘性食物和胶状食物）时舌后部运动的变化。食物的物理状态和个体差异的差异似乎影响舌压达到峰值前后的时间。在达到舌压峰值时评价舌运动。与凝胶状食物相比，蜂蜜状粘性食物能显著促进舌后表面的前移，今后应建立一种能同时评价吞咽困难患者舌后表面和舌骨运动的技术。少
