Insights
Infantile subglottic hemangiomas, rare congenital larynx lesions, require tailored management. This study recommends expectant care for small lesions, steroids or laser for moderate ones, and tracheostomy for large hemangiomas.
Area of Science:
- Pediatric Otolaryngology
- Congenital Airway Anomalies
Background:
- Infantile subglottic hemangiomas are rare congenital larynx lesions.
- Management of these lesions presents significant challenges.
- Stridor at birth is a common presenting symptom.
Purpose of the Study:
- To review experience with infantile subglottic hemangiomas.
- To classify and propose a treatment strategy based on lesion size.
- To evaluate treatment outcomes.
Main Methods:
- Retrospective review of 10 infantile subglottic hemangioma cases.
- Classification based on percentage of laryngeal lumen involvement.
- Treatment modalities included expectant management, systemic steroids, CO2 laser excision, and tracheostomy.
Main Results:
- Eight out of ten patients achieved cure.
- One patient developed subglottic stenosis.
- One patient died due to unrelated causes.
- Treatment success correlated with lesion size and chosen modality.
Conclusions:
- A size-dependent management approach is recommended.
- Small lesions (<25% lumen) may be managed expectantly.
- Moderate (25-60% lumen) and large (>60% lumen) lesions require intervention with steroids, laser, or tracheostomy.
Abstract:
Infantile subglottic hemangiomas are rare congenital lesions of the larynx that are difficult to manage. Our experience with 10 cases was reviewed. All patients presented with stridor at birth, or shortly after. The minimum follow-up was 6 months, with an average of 44 months. The patients were classified and treated according to the size of the hemangioma. The treatment included expectant management, systemic steroids, CO2 laser excision, and tracheostomies. Overall, eight patients were cured, one developed subglottic stenosis, and one died due to unrelated causes. We recommend that (1) patients with small lesions (< 25% of lumen) be treated expectantly, (2) patients with moderate lesions (25-60% of lumen) be treated with systemic steroids initially, and CO2 laser excision if steroids fail, and (3) patients with large lesions (> 60% of lumen) be treated with tracheostomies initially, and staged CO2 laser excision.
