Accreditation Check:
In this course, Dr. Catriona Steele describes the mechanisms of the swallowing process that can impact safety and efficiency. These mechanisms include bolus dwell time, maximum hyoid extension, laryngeal vestibule closure, and pharyngeal closure. Participants will learn how to objectively evaluate the function of each of these mechanisms using video fluoroscopic studies, and identify normal and pathophysiological presentations of each mechanism. Participants will have the opportunity to practice evaluating each mechanism using VFSS video from real patients.

Chapters & Learning Objectives

1. Mechanisms Behind Aspiration & Residue

This chapter introduces the mechanisms that can contribute to impaired swallowing, with an emphasis on the factors that cause aspiration and residue.

2. Bolus Dwell Time

This section provides additional detail regarding impaired bolus dwell time as a contributing factor of aspiration and residue, and teaches participants how to measure bolus dwell time.

3. Hyoid Excursion and Laryngeal Vestibule Closure

In this chapter participants will be given the skills needed to effectively identify maximum hyoid excursion, and to evaluate proper laryngeal vestibule closure. The chapter will conclude with a practice section in which participants will have the opportunity to evaluate maximum hyoid excursion via VFSS of a real patient.

4. Pharyngeal Constriction

Poor timing or incomplete pharyngeal constriction commonly contributes to aspiration and residue buildup in patients. The final chapter of this course will address how to evaluate pharyngeal constriction closure and provide an oppertunity for participants to practice these skills.
