Pharyngeal Residue Severity and Aspiration Risk in Stroke Patient Using Fiber-Optic Endoscopic Evaluation of Swallowing

Conclusion: There is a significant strong positive correlation between residue severity and penetration/aspiration in each anatomical site evaluated (valleculae and pyriform sinuses). Our results do not designate one site as riskier than the other because either can contribute to aspiration, but rather demonstrate penetration/aspiration to better correlate with the overall severity of the residue, perhaps as a better marker for pharyngeal inefficiency. This study offers insight into the association of residue severity with swallowing safety and efficiency.
