Insights

Acquired subglottic cysts in infants, often linked to neonatal intubation, present with stridor. Endoscopic marsupialization is the recommended treatment, showing no recurrences in this study.

Area of Science:

  • Pediatric Otolaryngology
  • Neonatal Care

Background:

  • Acquired subglottic cysts are rare but serious airway obstructions in infants.
  • Neonatal intubation is a known risk factor for developing these cysts.

Purpose of the Study:

  • To evaluate the clinical presentation and treatment outcomes of infants diagnosed with acquired subglottic cysts.
  • To compare the efficacy of different endoscopic treatment modalities.

Main Methods:

  • A 12-year retrospective case series at an academic tertiary referral pediatric medical center.
  • Eleven infants diagnosed with subglottic cysts were analyzed.
  • Treatments included endoscopic cyst rupture or marsupialization using CO2 laser or cup forceps.

Main Results:

  • All initial cyst management procedures were successful.
  • One symptomatic recurrence occurred after cyst rupture.
  • No symptomatic recurrences were observed in patients treated with endoscopic marsupialization (mean follow-up: 6 years).

Conclusions:

  • Subglottic cysts should be considered in ex-premature infants with stridor or respiratory difficulty, especially those with a history of neonatal intubation.
  • These cysts can develop even after short intubation periods (<24 hours).
  • Endoscopic marsupialization is the preferred treatment for acquired subglottic cysts.
