本文报告了我们的研究结果，以确定异常的发生率，在时间和程度的咽收缩的老年人口的投诉吞咽困难。我们对视频透视研究进行了回顾性分析，即，1996年至1999年进行的动态吞咽研究。本研究纳入了65岁以上的患者，他们的吞咽困难投诉没有明显的医疗或手术原因。测量最大咽部收缩的时间相对于食团咽部通过的开始、相对于食团到达上食管括约肌以及相对于食团尾部从上食管括约肌离开。最大咽部收缩的程度从侧位测量。将患者数据与从年轻（18-62岁）无吞咽困难对照组收集的数据和从老年（67-83岁）无吞咽困难对照组收集的数据进行比较。我们发现，73%的患者群体表现出不完全的咽部收缩相对于对照组，虽然咽部收缩的时间保持协调相对于在咽部的团的位置。咽部收缩不良，提示咽部无力，导致75%的误吸病例。
This article reports the results of our study to determine the incidence of abnormalities in ti I ming and extent of pharyngeal constriction in an elderly population with complaints of dysphagia. We performed a retrospective analysis of videofluoroscopic studies, i.e., dynamic swallow studies, that were performed between 1996 and 1999. Included in the study were patients over 65 years old without an obvious medical or surgical cause for their dysphagia complaints. The timing of maximum pharyngeal constriction was measured relative to the onset of bolus pharyngeal transit, relative to the arrival of the bolus at the upper esophageal sphincter, and relative to the exit of the tail of the bolus from the upper esophageal sphincter. The extent of maximum pharyngeal constriction was measured from a lateral view. Patient data were compared with data gathered from young (18-62 years old) nondysphagic controls and with data gathered from elderly (67-83 years old) nondysphagic controls. We found that 73% of the patient population demonstrated incomplete pharyngeal constriction relative to controls, although the timing of pharyngeal constriction remained coordinated relative to the position of the bolus in the pharynx. Poor pharyngeal constriction, suggestive of pharyngeal weakness, contributed to 75% of the cases of aspiration.
