尚未研究正常儿童口咽吞咽的时间测量。了解规范性时间测量的范围和变化可以定义异常吞咽，并有助于设计适当的补偿和康复治疗技术。本回顾性研究的目的是确定口腔充盈、口腔通过、喉闭合开始、推注到达谷的时间、咽延迟、咽通过和UES打开的时间测量值。对15名正常吞咽的儿科受试者进行了视频透视吞咽研究，分为三个年龄组和液体输送方法。利用平均值、标准差、百分比和中位数扩展来确定时间测量的关系。口腔充盈、口腔通过时间、喉闭合时间、UES打开时间和咽延迟时间的平均时间持续时间随年龄增加而增加。然而，年龄组之间没有显着差异，表明吞咽生物力学适应口腔和咽腔的生长。瓶与杯的喂养方法在口腔通过时间、喉闭合时间、UES打开和咽部延迟时间方面的平均持续时间增加。丸头位置相对于喉前庭关闭的发病随着年龄的增加和喂养方法而改变。时间措施没有显着不同的年龄组或喂养方法。在喉闭合开始时，推注位置位于或完全包含在谷中，似乎是功能性儿科吞咽的正常发现，并不表明延迟或疾病。
Temporal measures of normal pediatric oropharyngeal deglutition have not been studied. Knowledge of range and variation of normative temporal measures could define abnormal deglutition and assist in design of appropriate compensatory and rehabilitative treatment techniques. The purpose of this retrospective study was to determine temporal measurements for oral filling, oral transit, onset of laryngeal closure, time of bolus arrival at the valleculae, pharyngeal delay, pharyngeal transit, and UES opening. Videofluoroscopic swallow studies of 15 normally swallowing pediatric subjects were divided into three age groups and method of liquid delivery. Mean, standard deviation, percentages, and extension of the median were utilized to determine relationships of temporal measures. Mean temporal duration increased with age for oral filling, oral transit time, time of laryngeal closure, UES opening, and pharyngeal delay time. However, no significant differences were found between age groups indicating a deglutitive biomechanical adaptation to growth of the oral and pharyngeal cavity. Feeding method for bottle versus cup mean duration increased for oral transit time, laryngeal closure time, UES opening, and pharyngeal delay time. Bolus head location relative to onset of laryngeal vestibule closure changed with increased age and method of feeding. Temporal measures were not significantly different for age groups or feeding methods. Bolus location was at or fully contained in the valleculae at the onset of laryngeal closure and appeared to be a normal finding in functional pediatric swallows and is not indicative of a delay or disorder.
