Vertical and Anterior Displacement of the Hyoid
The distance in centimeters of the hyoid bone’s maximum displacement both vertically and anteriorly. It is measured by the difference between the hyoid at rest and the hyoid at maximum vertical/anterior displacement.
Vertical and Anterior Displacement of the LarynxThe distance in centimeters of the larynx’s maximum displacement both vertically and anteriorly. It is measured by the difference between the larynx at rest and the larynx at maximum vertical/anterior displacement Examples of the hyoid and larynx at rest and at maximum superior anterior displacement
Maximum Opening of the Upper Esophageal Sphincter (UES)
distance in centimeters of the maximum opening of the UES
Oral Transition Time (OTT)
The time it takes for a bolus, or a cohesive piece of material ready to swallow, to move through the oral cavity to the pharynx. It is measured from the initiation of backwards movement of the bolus by the tongue (position a) to the bolus head passing the ramus of the mandible (position b) on the VFSE (Logemann, 1986). Would be calculated as
OTT = a – b
Pharyngeal Transition Time (PTT)
The time it takes for the bolus to move through the pharyngeal cavity to the esophagus. It is measured from the bolus head passing the ramus of the mandible (position b) to the bolus tail passing through the Upper Esophageal Sphincter of the Esophagus (position c) (Logemann, 1986) Would be calculated as PTT = b – c
Reference points for measurements in Oral and Pharyngeal Transition Times
Stage Transition Duration (STD)
The time difference between the bolus first passing the ramus of the mandible and the onset of hyoid excursion (Robbins, Hamilton, Log, & Kempster, 1992).
The time between the first contact of the arytenoids and the epiglottis and the last contact between the arytenoids and the epiglottis ( Logemann, Pauloski, Rademaker, & Kahrilas, 2002).
Duration of Upper Esophageal Sphincter Opening (DUESO)
The time between the initial opening and closure of the UES ( Robbins, Hamilton, Log, & Kempster, 1992).
