Should granulomas be excised in children with long-term tracheotomy?

Area of Science:

• Pediatric Otolaryngology
• Respiratory Medicine
• Surgical Pathology

Background:

• Subglottic stenosis in children often necessitates tracheotomy.
• Granuloma formation is a frequent complication in these patients.
• The management of post-intubation or post-surgical airway granulomas remains a clinical challenge.

Purpose of the Study:

• To investigate the incidence and recurrence patterns of granulomas in children with tracheotomy-dependent subglottic stenosis.
• To evaluate the impact of granuloma management strategies (observation, excision, expansion surgery) on recurrence rates.
• To provide evidence-based recommendations for the clinical management of airway granulomas in this pediatric population.

Main Methods:

• Retrospective review of 265 rigid bronchoscopies in 50 children with subglottic stenosis.
• Data collected included patient demographics, stenosis type (congenital vs. acquired), tracheotomy details, and granuloma characteristics.
• Statistical analysis focused on granuloma development, recurrence rates, and association with different management interventions.

Main Results:

• Granulomas developed in 80% of children, irrespective of age, sex, race, reflux, tracheotomy duration, or stenosis type.
• Small to medium granulomas occurred in 28%, large in 6%, and none were obstructing.
• Recurrence odds were significantly higher after unexcised granulomas (3.0), excision (4.1), and expansion surgery (7.3) compared to no prior granuloma.

Conclusions:

• Non-obstructing granulomas are common in children with tracheotomy-dependent subglottic stenosis.
• Excision of non-obstructing granulomas does not reduce recurrence and may increase it.
• Conservative management of non-obstructing granulomas in stable tracheotomized children is recommended.
