Insights
Surgical excision of congenital subglottic hemangioma is effective. Subglottic stenosis risk is low, particularly when avoiding circumferential dissection and prior laser damage.
Area of Science:
- Pediatric Surgery
- Otolaryngology
- Laser Surgery
Background:
- Congenital subglottic hemangioma can cause significant airway obstruction in pediatric patients.
- Surgical intervention is often necessary to manage these lesions and ensure adequate airflow.
Purpose of the Study:
- To assess the risk of developing subglottic stenosis following surgical excision of congenital subglottic hemangioma.
- To identify factors contributing to subglottic stenosis in this patient population.
Main Methods:
- Retrospective analysis of 13 pediatric patients who underwent surgical excision for subglottic hemangioma.
- Procedures involved open surgical excision with the cricoid cartilage left open.
- Patients were monitored postoperatively in a pediatric intensive care unit.
Main Results:
- All 13 patients were successfully extubated post-surgery with no recurrence of hemangioma.
- Three patients (23%) developed subglottic stenosis (2 grade 1, 1 grade 2), all with favorable outcomes.
- Stenosis occurred in 2 cases following CO2 laser treatment and 1 after circumferential dissection.
Conclusions:
- Surgical excision of congenital subglottic hemangioma allows for successful extubation in all pediatric cases.
- The risk of subglottic stenosis is limited and appears associated with circumferential dissection, especially if preceded by laser treatment.
Objective:
To evaluate the risk of subglottic stenosis after surgical excision of congenital subglottic hemangioma.
Design:
Retrospective analysis and case series.
Setting:
Tertiary care teaching hospital.
Patients:
A total of 13 pediatric patients diagnosed with subglottic hemangioma with unilateral, bilateral, or circular lesions and more than 50% airway obstruction between 1992 and 2001.
Intervention:
Open surgical excision was performed as a single-stage procedure either as primary or secondary intention. The cricoid cartilage was left open at the end of the procedure. Postoperative intubation was carried out in a pediatric intensive care unit.
Main Outcome Measure:
An adequate airway after surgical excision.
Results:
All patients were successfully extubated. No recurrence was noted. Three patients developed subglottic stenosis, two grade 1 and one grade 2. All 3 showed a favorable outcome and did not require reintubation. One needed endoscopic management of the stenosis. Of these 3 cases, 2 occurred after carbon dioxide laser treatment (out of 3) and 1 after circumferential dissection (out of 3).
Conclusions:
Extubation after surgery was successful in all cases of subglottic hemangioma. Risk of subglottic stenosis was limited and occurred only after circumferential dissection, especially if associated with prior traumatic laser damage of the hemangioma.
