Abstract:
Objective:Aspiration is a major concern for children with dysphagia because aspiration has been known as the primary etiology leading to recurrent pneumonia, and severe impairment of lung function in pediatric populations.This study aimed to examine the differences in each temporal measure between children with and without aspiration and investigate the effect of bolus consistency on the temporal measures.
Methods:Forty-two children ranging in age from 1 year to 3 years and 11 months were included in this study. A referral for a videofluoroscopic swallowing study (VFSS) was made. They were divided into two groups according to the presence or absence of aspiration. Sixteen children were aspirators, and twenty-six children were non-aspirators.Oropharyngeal temporal measures were analyzed using frame-by-frame analysis.
Results:The delayed initiation of pharyngeal swallowing, delayed laryngeal closure, and poor bolus transition in the pharyngeal stage were associated with the risk of aspiration in children with dysphagia. The bolus consistency did not affect the oropharyngeal temporal measures.
Conclusion:The objective temporal data in this study, including the durations and onset of physiological events in relation to bolus movement, can be used for future research to compare the swallowing functions between groups of children with various etiologies and age ranges.
