Vocal fold cysts are diagnosed based on gathering a case history, perceptual examination, and laryngeal imaging.
[4] Initial treatment of the cysts involves voice therapy to reduce harmful vocal behaviours.
[2] They are typically found in the middle portion of the upper lamina propria of the vocal folds.
[11] A medical and voice history can help distinguish patterns of misuse and phonotrauma to assist in diagnosis.
[11] Further, videostroboscopy tends to show increased submucosal swelling in the affected areas of the vocal fold(s)[9] More recently, other technologies have been introduced to assist with obtaining imaging of the vocal folds, including the use of Narrow-band imaging (NBI.
[12] NBI has been found to help improve visual identification of vocal fold cysts in some cases.
If the vocal fold cyst(s) are presumed to be congenital, the patient should have a history of presenting with a hoarse voice.
[4] It is important to keep the vocal fold tissue healthy and hydrated, and when possible to limit the quantity of speaking in order to avoid damage.
[15][16] Vocal fold cysts are most responsive when surgical intervention is supplemented with voice therapy.
[15] Vocal fold tissue can be preserved during surgery by raising a micro-flap, removing the cyst, then laying the flap back down.
[19] Congenital ductal cysts (those caused by blockage of a glandular duct) may be treated by marsupialization.
[2] In absolute vocal rest, activities such as talking, whispering, whistling, straining, coughing, and sneezing are restricted.
[21] Once adequate healing has occurred, the patient may be transitioned to relative vocal rest, which typically involves 5 to 10 minutes of breathy voicing per hour.
Professional voice users who do not experience substantial limitations due to their cysts may choose to forego surgery.
[8] Considering that some cysts remain stable over long periods of time, voice therapy alone may be an option for those who are resistant to surgery.
[15] Another option for those who are unwilling to undergo surgery is vocal fold steroid injection (VFSI).
[2] Up to 20% of patients show scarring, polyps or vascular changes of the vocal folds following surgery.
