Acquired subglottic cysts primarily affect preterm infants, often linked to respiratory issues and requiring intubation. Long-term follow-up is crucial due to recurrence and potential stenosis risks.
Area of Science:
- Pediatric Otolaryngology
- Neonatal Care
- Respiratory Medicine
Background:
- Acquired subglottic cysts are rare but significant airway lesions in neonates.
- Prematurity and conditions like bronchopulmonary dysplasia are associated risk factors.
- Endoscopic evaluation is key for diagnosis.
Purpose of the Study:
- To evaluate the diagnostic approach, treatment strategies, and outcomes for acquired subglottic cysts.
- To identify risk factors and long-term sequelae in affected neonates.
Main Methods:
- Retrospective analysis of 172 preterm neonates over 10 years at a tertiary center.
- Endoscopic examination for diagnosis and identification of subglottic cysts.
- Review of treatment procedures and follow-up data.
Main Results:
- 17 children diagnosed with subglottic cysts; 98% were premature (28±4 weeks gestation).
- 76% had a history of hyaline membrane disease or bronchopulmonary dysplasia; all required neonatal intubation.
- Mean age at diagnosis was 8 months; 30% had associated laryngotracheal anomalies. Six procedures achieved recovery.
Conclusions:
- Acquired subglottic cysts predominantly impact extremely preterm infants.
- Long-term follow-up is essential due to the risk of cyst recurrence and secondary subglottic stenosis.

Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants.
