We observed the laryngeal closure during swallowing using 320 Area Detector CT ofhealthy elderly and examined the effect of age on the movements involved inswallowing. Swallowing of dysphagic patients were also observed and thepathological conditions underlying disabilities were analyzed. Elderly showed alonger swallowing duration with longer pharyngeal constriction. It probably derivesfrom a compensation of weaker pharyngeal constriction with aging. Some dysphagicpatients showed aspiration during or after swallowing. It was found that a delayedonset of laryngeal closure caused the aspiration. Our results promoted theunderstanding of dynamic mechanisms of laryngeal closure during swallowing, whichhave not been thoroughly identified. In the next step, understanding of mechanismsof swallowing disorders and building of swallowing exercises are expected.

应用320面积探头CT观察健康老年人吞咽时喉部闭合情况，探讨年龄对吞咽运动的影响。观察吞咽困难患者的吞咽情况，分析致残的病理情况。老年人吞咽持续时间较长，咽部收缩时间较长。这可能是由于随着年龄的增长咽部收缩减弱的一种补偿。部分吞咽困难患者吞咽时或吞咽后出现误吸现象。结果发现，误吸是喉部延迟闭合引起的。我们的结果促进了对吞咽过程中喉部闭合的动力学机制的理解，这一机制尚未完全确定。下一步，对吞咽障碍的发病机制和吞咽训练的建立进行了深入的研究。
