目的：描述吞咽困难老年人舌骨运动的时间、协调性和程度，并评价舌骨运动对食管上括约肌张开的影响。设计：对1996年1月至1999年12月期间进行的动态吞咽研究进行回顾性分析。纳入研究的患者年龄在65岁或以上，吞咽困难没有明显的医疗或手术原因。采用单因素方差分析，将患者人群舌骨运动的时间和距离测量值与60名年轻（范围18-62岁）和23名老年（范围67-83岁）无吞咽困难的对照受试者进行比较。舌骨运动对上食管括约肌开放的影响进行分析，使用列联tables.Results：在老年人群吞咽困难，吞咽手势和丸定时的协调是完整的，舌骨抬高缓慢，最大舌骨抬高的持续时间减少，但适合患者的年龄。舌骨升高远比正常的小丸大小，但患者无法保持这种策略在较大的丸swallows.Conclusion：舌骨移位的老年患者吞咽困难的程度增加可能是一个必要的补偿，旨在尽量减少舌骨抬高上食管括约肌开口的短时间的影响。
Objectives: To describe the timing, coordination, and extent of hyoid movement in a population of older adults with dysphagia and to evaluate the effect of hyoid movement on upper esophageal sphincter opening.Design: A retrospective review of dynamic swallow studies performed between January 1996 and December 1999 was done.Subjects: Patients included in the study were 65 years or older, without an obvious medical or surgical cause for their dysphagia. Timing and distance measures of hyoid movement from the patient population were compared with those from 60 younger (range, 18-62 years) and 23 older (range 67-83 years) control subjects without dysphagia using 1-way analysis of variance. Analysis of the effect of hyoid movement on upper esophageal sphincter opening was performed using contingency tables.Results: In an older population with dysphagia, the coordination of swallowing gestures and bolus timing was intact, hyoid elevation was slow, and the duration of maximal hyoid elevation was reduced, but appropriate for the age of the patients. The hyoid bone elevated farther than normal for small bolus sizes, but the patients were unable to maintain this strategy in larger bolus swallows.Conclusion: An increased extent of hyoid displacement in older patients with dysphagia may represent a necessary compensation designed to minimize the effect of the short duration of hyoid elevation on the upper esophageal sphincter opening.
