Laryngeal cyst

Laryngeal cysts are cysts involving the larynx or more frequently supraglottic locations, such as epiglottis and vallecula.[1] Usually they do not extend to the thyroid cartilage.[2] They may be present congenitally[3] or may develop eventually due to degenerative cause.[4] They often interfere with phonation.

Presentation

Hoarseness is the most common presenting symptom, while pain, stridor or laryngeal obstruction are unusual complaints.[5] They may cause significant respiratory obstruction leading to dyspnoea or respiratory distress[3] and even cyanosis, and jugular and epigastric retractions.[1] Congenital lesions may present with severe airway obstruction at birth calling for emergency intervention and intubation.[1]

Diagnosis

Types

There are three types of laryngeal cysts, namely, mucous, hemorrhagic and congenital.[6] However, a new classification system for congenital laryngeal cysts on the basis of the extent of the cyst and the embryologic tissue of origin, is proposed for the ease of initial surgical management.[7]

Treatment

Treatment can be medical or surgical.[8] Laser endoscopic treatment is often preferred.[9] Voice therapy is sometimes necessary.

Epidemiology

Congenital cysts of the larynx with incidence of about 1.8 in 100,000 newborns.[1]

Laryngeal cysts form 4% of all laryngeal tumors[6] or about 5% of benign laryngeal lesions.[10] Prevalence is about equal between the sexes.[11]

gollark: Sometimes I accidentally appear slightly prescient by splitting statements across multiple lines such that I end up preempting an obvious follow-up question.
gollark: Yes, that sounds quite bad.
gollark: Oh.
gollark: Unethical why?
