A videofluoroscopic swallow study (VFSS) is an important tool for speech-language pathologists to leverage during assessment and treatment planning for persons experiencing dysphagia. However, a lack of standardized VFSS practice currently exists, and many clinicians lack knowledge regarding best practice. In this course, we review metrics for rating swallowing efficiency, i.e., pharyngeal residue. We will review both visuoperceptual and quantitative pixel-based methods for capturing residue severity.

Chapters & learning objectives
1. What Is Pharyngeal Residue?
In this chapter, we will explain what pharyngeal residue is and where it may be located.
2. Visuoperceptual Approaches to Measuring Residue Severity
In this chapter, we will discuss several different visuoperceptual approaches to describing residue severity. These include both bolus-derived and space-derived measures. We will discuss the reliability of these measures as reported in the literature.
3. Quantitative Pixel-Based Methods of Measuring Residue
In this chapter, we will describe and illustrate pixel-based measurement of residue severity. We will discuss different approaches to normalizing these measures to anatomical reference scalars and lead participants through a measurement activity.
