A 10-year study of the etiopathogenesis of cysts with a study of seromucinous glands in vocal folds.

Objective: An increasing number of vocal fold cysts excised, as compared to polyps, over the last decade led us to review these cases. We found a statistically significant increase in cysts excised as compared to polyps, over the latter 5-year period (2013-2017). This prompted us to analyze possible factors responsible for this increase.
