Besides, what causes residue in pyriform sinus?
[1] identified both pharyngeal constriction and pharyngeal shortening as factors relevant for the accumulation of pyriform sinus residue, and also implicated tongue driving force as a factor contributing to vallecular residue.
Additionally, what is the function of the Vallecula? The epiglottic vallecula is a depression (vallecula) just behind the root of the tongue between the folds in the throat. These depressions serve as “spit traps”; saliva is temporarily held in the valleculae to prevent initiation of the swallowing reflex.
Hereof, what is Vallecular residue?
The Relationship of Vallecular Residue to Oral Involvement, Reduced Hyoid Elevation, and Epiglottic Function. Successful emptying of the vallecular spaces is one variable that is used to assess the integrity of the pharyngeal stage of the swallow.
What causes delayed swallowing?
A wide range of diseases can cause swallowing problems, which your doctor may call “dysphagia.” These include: Disturbances of the brain such as those caused by Parkinson’s disease, multiple sclerosis, or ALS (amyotrophic lateral sclerosis, or Lou Gehrig’s disease)
