Study of barium dynamic imaging of pharynx in patients with deglutition disorder and normal swallowing

Objective:To investigate the method and value of barium dynamic imaging of pharynx in patients with deglutition disor-der(DD) and normal swallowing.Methods:The study population of the normal swallowing consisted of 299 cases and the deglutition dis-order consisted of 235.In order to observe the swallowing status compared with the transporting time of pharynx measured in this study,all cases were examined with anterior-posterior and lateral projection dynamic acquisition from C7 to the skull base.The dynamic imag-ings of 235 deglutition disorder patients were studied.Results:There was no statistical difference of transporting time of pharynx between the different age and sex.The transporting time of pharynx for normal cases was(0.7273±0.2132)s.235 cases of deglutition disorder oc-curred mainly in patients of esophageal carcinoma after radiotherapy or resection,stroke,laryngeal tumor,the transporting time of pharynx for the deglutition disorders cases was(0.9288±0.1627)s.Conclusion:This method is the first choice in the examination of deglutition disorder,it can record the entire process of barium sulphate fluid flowing through the pharynx.
