[Dysphagia] Pharyngeal reflex Triggering
Welcome to the list.
For pharyngeal delay we measure from the moment the bolus passess the
point where the mandible crosses the tongue base to the moment that
hyo-laryngeal elevation begins. I am not in my office at this moment, but
much of the literature promotes this definition for pharyngeal delay time.
I hope that helps.
