Abstract

Subglottic cysts are rare but can cause significant airway obstruction that potentially threatens infants’ lives. It is critically important to suspect subglottic cysts in infants with upper-airway obstructive symptoms because it can be treated effectively with only marsupialization without tracheostomy or complicated surgery. Here, we report an infant case of subglottic cyst, who showed prominent stridor and respiratory distress that abruptly progressed 2 months after extubation. The patient was born prematurely and had a history of endotracheal intubation in for a total of 16 days. He was stable with minimal stridor without respiratory distress until he was successfully discharged from the neonatal intensive care unit. However, he showed abrupt progress in stridor and respiratory difficulty about 2 weeks after discharge. Laryngoscopic exam revealed multiple subglottic cysts obstructing the trachea, and all of them were successfully removed by marsupialization. No recurrence of subglottic cysts was observed for 12 months thereafter. Subglottic cysts should be primarily suspected in infants with stridor, especially with a history of prematurity and intubation. Increased awareness of this fatal but curable condition is needed for timely and proper management.
