Definition / general
- Ductal (75%) or saccular (24%); lined by squamous or respiratory mucosa or both
- Ductal cyst: due to dilation of mucous glands; small, superficial, usually in true vocal cord or epiglottis
- Laryngocele: air containing dilation of tip of ventricle that communicates with ventricle via a narrow stalk; either internal or external or both; may become infected and accumulate pus (laryngopyocele)
- Oncocytic cyst: type of ductal cyst lined partially or completely by oncocytes; often has papillary infoldings; may recur; rarely is diffuse within the larynx
- Saccular cyst: due to distention of laryngeal saccule; large, deep, often within ventricle; may cause neonatal airway obstruction; contains mucus
- Tonsillar cyst: squamous lined crypt-like structure with abundant lymphoid follicles in cyst wall
