Laryngeal cyst

Dr Dan J Bell and Dr Bruno Di Muzio et al.

Laryngeal cysts can occur in any part of the larynx, but are more frequent in supraglottic locations, such as the epiglottis and vallecula. The prevalence of each location varies on different studies. 

The laryngeal cysts represent a rare group, about 5%, of benign laryngeal lesions 1. There is no gender predilection 3.

Normally they are examination findings in patients with non-specific symptoms or who are asymptomatic. Patients can have laryngeal stridor or dyspnoea 2.

The lesions can cause significant respiratory obstruction, and even death, if not properly treated.

Different forms of treatment have been described for laryngeal cysts, such as aspiration, marsupialisation with laser ablation and complete excision. Recurrence is directly related to the maintenance of remnants of the cyst wall 2.
