Insights
Propranolol effectively treats infantile subglottic hemangiomas (SGH), resolving airway obstruction without surgery in all cases. While most infants showed stable regression, two experienced regrowth, necessitating further long-term study.
Area of Science:
- Pediatric Otolaryngology
- Neonatal Care
- Pharmacology
Background:
- Subglottic hemangiomas (SGH) are rare infant tumors causing significant airway obstruction.
- Existing treatments carry potential complications.
- Propranolol shows emerging promise for SGH management.
Purpose of the Study:
- To evaluate the efficacy and safety of propranolol in infants with subglottic hemangiomas.
- To assess the need for tracheostomy or surgical intervention during propranolol treatment.
Main Methods:
- A consecutive case series of 10 infants with SGH and airway obstruction.
- Treatment with propranolol at a dosage of 2 mg/kg/day.
- Mean treatment duration of 7.7 months.
Main Results:
- Complete symptom resolution in all 10 infants.
- Eight infants achieved stable regression.
- Two infants experienced lesion regrowth after 9 months.
- No infant required tracheostomy or surgical removal.
Conclusions:
- Propranolol is a promising and effective treatment for SGH with rapid onset.
- It may reduce or eliminate the need for tracheostomy and allow corticosteroid dose tapering.
- Long-term outcomes require further investigation with repeat laryngoscopy.
Background:
Subglottic hemangiomas (SGH) are a rare tumour, often associated with significant airway obstruction in infants. Current treatment options, while effective, often expose the infant to potential complications. Emerging evidence suggests a role for the beta blocker propranolol in the initial management of SGH.
Methods:
We report our experience with propranolol 2 mg/kg/day in 10 consecutive cases of SGH with significant airway obstruction (age range 2–4 months).
Results:
After a mean of 7.7 months of treatment, symptom resolution was observed in all cases and eight infants had regression and were stable. Two patients experienced regrowth after 9 months of therapy. To date, no infant has had a tracheostomy or surgical removal of the lesion.
Conclusions:
Early results with propranolol are promising; it is effective in controlling SGH, has a rapid onset of action, appears to obviate the need for tracheostomy and can allow tapering of the corticosteroid dose. Repeat laryngoscopy will be required to map the clinical course of these children and elucidate the long-term benefits of propranolol.
