Acquired paediatric subglottic cysts: A series from Manchester

Cisto subglótico: uma causa rara de estridor laríngeo

“…(1)(2)(3)(4) The first was published in 1968, when Wigger & Tang reported the case of an infant who died from airway obstruction caused by SGCs.…”

“…(3,5) Symptoms of laryngeal cysts depend on the size and the location of the cyst and include a change in the tone of voice, dysphonia, hoarseness, dysphagia, laryngeal stridor, and dyspnea. (6) This condition is often misdiagnosed as laryngomalacia, asthma, croup, or other diseases, due to the fact that it manifests as recurring respiratory infections, stridor, and wheezing.…”

“…The mild stridor persisted, occurring managing preterm infants discharged from ICUs who present with airway obstruction, physicians should consider SGCs. (3) In children with recurrent stridor, laryngoscopy is the gold standard for the diagnosis of SGCs, because it allows early recognition of laryngeal diseases, including rare cases of cysts. Intubation remains the main means of ventilatory support in extremely premature neonates, and it can induce local subglottic trauma, which is the logical explanation for the genesis of SGCs.…”

“…Even when treated appropriately (surgically of clinically), SGCs recur in 19-60% of cases, especially in the first 4 months after the initial procedure. (2,3,5) A history of intubation, prematurity, and stridor should raise the clinical suspicion of SGCs. (3) All patients with recurrent stridor should be submitted to laryngoscopy in order to hasten the diagnosis and treatment.…”

“…Among infants presenting with stridor and undergoing direct laryngoscopy or bronchoscopy, SGCs are diagnosed in 7%. (3,4) In addition, SGCs are an intubation-related process and represent an uncommon cause of stridor in infants. (7) When…”
