...we went outside into the unit, he sipped a tiny bit of barium and they filmed as he swallowed ....we were able to view his throat muscles, pharynx. esophagus,..even his teeth...and they gave us a dvd of it ..
....swallowing triggers a reflex that passes the food through the pharynx (the canal that connects the mouth with the esophagus). During this stage, the throat muscles tighten to raise the larynx (voice box)...that motion closes off the airway, breathing stops momentairly to prevent food or liquid from entering the lungs so that what you swallow goes into the esophagus to the stomach.....
.....his throat muscles moved only the slightest bit and his larynx did not lift and close over his airway enough to protect his airway...anything that he swallowed would go partially into his lungs.
This could likely be a permanant situation..however,
