There are several possible causes of vocal fold cysts: # They can be congenital. # They can result from the blockage of a mucous gland's excretory duct. In this case, they are sometimes referred to as retention cysts. # They can be the result of phonotrauma. Phonotrauma refers to behaviours that can lead to vocal fold injuries, such as vocal overuse (i.e. too much speaking), vocal misuse (i.e. speaking in an unnaturally high or low pitch), or vocal abuse (i.e. yelling or whispering for prolonged periods). Vocal folds vibrate during phonation resulting in repeated collisions of the right and left vocal folds. Phonotrauma subjects the vocal folds to excessive mechanical forces during these vibratory cycles, which can lead to the development of a wound. It is the healing of these wounds, which leads to tissue re-structuring, that can result in a vocal fold cyst.
