Quiste laríngeo congénito: Una rara causa de estridor en niños

Congenital Saccular Cyst of the Larynx: A Rare Cause of Stridor in Neonates And Infants

“…As the size of the cyst increases, stridor may also increase and be associated with voice changes (perceived as hoarse or low crying), episodes of cyanosis, retraction, and difficulty for feeding, even reaching a complete obstruction of the airway. 2 The differential diagnosis of SC should include ductal cysts, laryngocele, haemangioma, hamartoma and teratoma, among others. 8 Another difference is that, in laryngomalacia, stridor decreases in the prone position, whereas in lateral SC, symptoms decrease when the patient is lying on the affected side and increase in the contralateral position.…”

“…3,11---13 On the other hand, laryngomalacia never causes changes in the quality of voice. 2 Due to their rarity, it is difficult to determine the optimal surgical strategy. 1 The diagnosis is suspected through the symptoms and clinical course.…”

“…2 Moreover, being a rare entity, it is not generally considered during the evaluation of children with congenital stridor.…”

“…1,2 Saccular cysts (SC) are unusual congenital lesions which clinically appear in the neonatal period or early infancy. The main cause in newborns and infants is laryngomalacia.…”

“…The main cause in newborns and infants is laryngomalacia. 2 The most common symptom is inspiratory stridor and the initial presentation may mimic laryngomalacia. 3 They develop at the supraglottic level by a blockage of the opening of the saccule of the laryngeal ventricle.…”
