For several factors, not yet fully explained until now, infant deglutition may persist after changing the primary teeth and such swallowing is classified as atypical swallowing. Possible causes: finger sucking, bottle feeding, sucking the tongue and mouth breathing. There is no consensus about the etiology of atypical deglutition.
The aim of this study was to compare the oropharyngeal space in side-view radiographs of children with atypical deglutition and normal deglutition.
Retrospective study, by means of cephalometric analysis of side-view radiographs, measuring the anteroposterior distance of the lumen of the airway in two groups: 55 cephalograms from the experimental group (with atypical deglutition) and 55 side-view radiographs from the control group (normal deglutition). Measurements from the groups were compared using Mann-Whitney U test and a p value <0.05 was considered as an indication of statistical significance.
The median in the control group was 10 mm and in the experimental group it was 7 mm, with a statistically significant difference (p <0.001).
The oropharyngeal space is reduced in the group with atypical deglutition.
由于目前尚未完全解释的多种因素，婴儿的吞咽可能会在更换乳牙后持续存在，这种吞咽被归类为非典型吞咽。可能的原因：手指吸吮、奶瓶喂养、舌头吸吮和口呼吸。对于非典型吞咽的病因尚无共识。
本研究旨在比较非典型吞咽和正常吞咽儿童的侧位片咽腔空间。
回顾性研究，通过侧位头颅侧位片的头影测量分析，测量两组气道管腔的前后距离：实验组（非典型吞咽）55 个头颅侧位片和对照组（正常吞咽）55 个侧位片。使用曼-惠特尼 U 检验比较两组的测量值，p 值<0.05 被认为具有统计学意义。
对照组的中位数为 10mm，实验组为 7mm，差异具有统计学意义（p<0.001）。
非典型吞咽组的咽腔空间缩小。
