Swallowing function in the eldaly

通过对65岁以上吞咽困难或咽部异常感患者进行改良测压和改良咽-食道透视检查，得到以下结果。我们将12例接受测压的患者分为两组：6例神经肌肉疾病患者和6例无神经肌肉疾病患者。但两组间吞咽压传导曲线模式及吞咽压传导速度均无明显差异。并将54例患者分为3组：神经肌肉疾病组18例，无吞咽障碍组20例，各种原因吞咽困难组16例。咽部和喉部早产儿X线检查阳性率分别为15例(81%)、8例(40%)和8例(50%)。本文通过对20例无吞咽障碍患者的X线透视检查，未发现与吞咽有关的解剖成分的常见病理运动，本研究对上述几点进行了研究，旨在阐明吞咽反射启动障碍是老年人吞咽困难的主要原因。我们得到的事实是，迟发性吞咽反射启动的发生率在老年人中有所上升，但未能得到这一现象的确切原因。

We have got the following results through the investigations of a revised manometry and a revised pharyngo-esophageal fluorography applied to the patients with dysphagia or abnormal sensations in the throat who are 65 years old or older. We divided the 12 patients who underwent the manometry into two groups ; 6 patients with neuromuscular disease and 6 without disease. But there seems no difference between two groups as to both the patterns of conduction curves of swallowing pressure and also the conduction velocity of the swallowing pressure. And we also divided the 54 patients who underwent the pharyngo-esophageal fluorograpgy into 3 groups ; group 1 of 18 patients with neuromuscular disease, group 2 of 20 patients without any dysphagic disease, and group 3 of 16 patients with dysphagia of miscellaneous causes. The percentages of positive fluoroscopic findings of premature flow into the pharynx and the larynx are 15 cases (81%), 8 cases (40%), and 8 cases (50%) respectively. We could not find any common pathological movements of anatomical components involved in swallowing in the series of fluoroscopic examination of group 2 of 20 patients without any dysphagic disease.In this study, several points mentioned above were investigated in order to clarify the disorder of swallowing reflex initiation which are thought to be the main cause of dysphagia in the elderly. We got the facts that the incidence of delayd swallowing reflex initiation goes up in elder generations but failed to get the precise cause of that phenomena.
