Abstract
The intake behavior of humans and across mammalian species develops with bottle feeding along with mastication. Bottle feeding is a combination of sucking and swallowing in team with respiration. In the present investigation, based on the results of both videofluoroscopy and laryngofiberscopy performed on 3 patients, we investigated the mechanism of bottle feeding disorder. The results showed the cause of this disorder to possibly be the joint presence of the laryngeal closure function as an airway protective function and either laryngomalacia or a delayed swallowing reflex. In addition, if some impairment exists in the interlinkage between swallowing and respiration, then the link between sucking and swallowing may break down, thereby resulting in bottle feeding disorder. Based on the foregoing observations, the findings of both videofluoroscopy and laryngof iberscopy are thus considered to play a key role in elucidating the mechanism of the bottle feeding disorder.
