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
