项目摘要

When bolus is formed and maintained during swallowing, oral cavity and pharynx cavity are interrupted by the contact of tongue and the palate. In clinically, dysphagia is often induced with this interrupting dysfunction. There are many method of evaluating the tongue surface shape in forming a bolus by two-dimensional measurements, but it is too difficult to evaluate whole tongue shape. In this paper, standardization using the three-dimensional ultrasound system was researched to clarify that the dysphagia involved with the defection and/or the dysfunction of the tongue and the plate. And characteristically changing of tongue shape in holding water on its surface is examined according to the volume of water bolus.The objects were six healthy adult male (average age 26.0 years old). The operation of the ultrasound probe was standardized by using the electronic motor to improve the image accuracy before evaluating of the tongue shape. The aluminum marker was stuck on the tongue surface as reference. The certain volume of water was hold in the mouth, and a three-dimensional image of the tongue shape was scanned the probe from submandibular. Measuring of the tongue and the palate contact way was done in three directions (the width, the rear length, and the depth) with the reference marker. It was suggested that was the least distortion with condition of probe operation setting (20cm in the rotation radius and rotational speed 1.6°/s and frequencies 6.0MHz) for tongue imaging. Using 3-D US, the tongue surface shape and the its changing were able to measure objectively, the most of objects corresponded to changing a volume of bolus by three-dimensionally changing the tongue surface shape. This three-dimensional tongue shape observation with forming bolus is effective to the evaluation and the diagnosis of not only abnormal form of the tongue but also functional disorder.

当在吞咽期间形成并维持食团时，口腔和咽腔被舌和腭的接触中断。在临床上，吞咽困难往往是由这种中断功能障碍引起的。通过二维测量来评价舌面形状的方法有很多，但评价整个舌面形状太困难。本文通过三维超声系统的标准化研究，阐明了吞咽困难与舌板缺损和/或功能障碍的关系。以6名健康成年男性（平均年龄26.0岁）为研究对象，观察了舌面持水时舌形的变化特征。通过使用电动马达来标准化超声探头的操作，以在评估舌形之前提高图像准确性。将铝标记物粘在舌表面上作为参考。在口腔中含一定量的水，从下颌下探头扫描舌体三维图像。用参考标记在三个方向（宽度、后部长度和深度）上测量舌与腭的接触方式。结果表明，在舌像探头旋转半径为20 cm，旋转速度为1.6°/s，频率为6.0MHz的条件下，舌像畸变最小。三维超声能客观地测量舌面形态及其变化，大部分目标对应于通过三维改变舌面形态来改变弹丸体积。这种三维舌形观察与形成团是有效的评价和诊断不仅是异常的舌形，而且功能障碍。
