Insights
Acquired subglottic cysts in infants, often linked to intubation, can present acutely after extubation. Early diagnosis and intervention are crucial for high-risk infants to manage rapidly enlarging cysts.
Area of Science:
- Pediatric Otolaryngology
- Neonatal Critical Care
Background:
- Acquired subglottic cysts in infants are typically linked to early life intubation.
- Most cases present with delayed symptoms, days to months post-extubation.
Purpose of the Study:
- To report a case of subglottic cyst with an atypical, acute presentation.
- To emphasize the possibility of rapid enlargement shortly after airway extubation.
Main Methods:
- Case report detailing a unique presentation of subglottic cyst.
- Review of clinical course and management considerations.
Main Results:
- The reported subglottic cyst presented acutely and enlarged rapidly after extubation.
- This contrasts with the typical delayed presentation of such cysts.
Conclusions:
- Subglottic cysts can manifest acutely post-extubation, not just delayed.
- Close post-extubation monitoring for early diagnosis and intervention is vital in high-risk infants.
Abstract:
Acquired subglottic cyst in infancy is almost always associated with episodes of early life intubation. Most cases typically presented late, usually days to months after extubation. We report a case of a subglottic cyst with different presentation than the norm. This case highlights that subglottic cyst can present acutely, and rapidly enlarging soon after the airway extubation. As the management of a large subglottic cyst can be challenging, a close observation for early diagnosis and intervention are recommended post extubation in the high-risk cases, such as in the premature infant.

Endotracheal Tube Extubation
Procedure
Extubation removes the endotracheal tube (ETT) from the patient on mechanical ventilation. It requires a well-coordinated, multidisciplinary approach involving physicians, nurses, respiratory therapists, and other healthcare professionals.
