A cyst is a mass madeup of a collection of material, usually mucus that is surrounded by a membrane. It is found underneath the mucosa, within the superficial lamina propria, the layer that is important for normal voice function.
Cysts generally cause painless hoarseness. The hoarseness results from irregularities in vocal fold closure as well as irregularities in vibration, both the result of the bulk and location of the cyst. In some cases, the voice change may be accompanied by a sensation of a foreign body at the level of the vocal folds, or a feeling of wanting to clear the throat or cough.
Most commonly, a cyst can be removed by Microlaryngeal surgery and Pulsed Dye Laser surgery as well at the same time. It is important to remove the root completely to prevent the recurrence.
