For vocal fold cyst edits:

This source has a good overview of the different types of cysts and general information on them: the book was published in 2014 so it is within the 5 year recommendation for medical articles.

Useful information from pages 105-106:

Goes into detail about the differences between epidermoid and mucous retention cysts

- former tend to be white in colour, latter tend to be yellow

- epidermoid cysts tend to form from trauma

- mucous retention cysts are caused by blockage of a gland

Vocal dynamics
Vocal fold cysts cause the properties of the vocal folds to change. When a cyst is present on a vocal fold, the cover of the vocal fold becomes more stiff and increases in mass. The increased mass and stiffness tends to result in hyperkinetic muscular movement during phonation. Hyperkinetic movement is characterized by increased rigidity in the affected vocal fold(s). This hyperkinetic movement results in the voice being perceived as hoarse. (see Signs and Symptoms) Specifically, the presence of a vocal fold cyst leads to an asynchronous mucosal wave of the vocal folds during phonation.

Under diagnosis:

Further, videostroboscopy tends to show increased submucosal swelling in the affected areas of the vocal fold(s).

Under treatment:

Although vocal fold therapy is useful for preventing vocal fold cysts caused by phonotrauma and for promoting safe vocal practices, vocal fold cysts tend not to respond to therapy alone and require surgery for full repair.

Under diagnosis:

If the vocal fold cyst(s) are presumed to be congenital, the patient should have a history of presenting with a hoarse voice.
