Abstract:
This erratum notifies the readers of the Dysphagia journal of an error in the original published version of this manuscript. In that manuscript, a previously available open source spreadsheet tool was used to calculate the position of the posterior laryngeal air column on lateral view videofluoroscopic images as a proxy for the bottom of the pharynx. We have subsequently been made aware of an error in the mathematical formula built into the spreadsheet, which resulted in a reversal of the results for the X and Y planes of measurement. This erratum provides corrections to the results and interpretations of the original manuscript.

Chronic Pharyngitis
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...

Nasopharynx
The nasopharynx, bordered by the conchae of the nasal cavity, serves exclusively as an air conduit. In its superior region, the pharyngeal tonsils or adenoids are located. These tonsils are clusters of lymphoid reticular tissue akin to a lymph node. The precise...
