what is it called when the vocal cords are swollen and thick due to inflammation?
When the refluxing affects primarily the voice production system - the larynx and pharynx - it is called laryngopharyngeal reflux disease (LPR). It may also be called reflux laryngitis. Laryngopharyngeal Reflux: LPR has caused inflammation (redness and swelling) of the back of the larynx. The vocal fold mucosa is irritated and copious thick secretions cover the vocal folds. This causes discomfort and irregular mucosal wave vibration, leading to voice changes.
