Diagnosing tracheostomy allergy: Improving airway outcomes in pediatric patients with an active larynx

Area of Science:

• Pediatric Otolaryngology
• Allergy and Immunology
• Pediatric Airway Management

Background:

• Children undergoing airway reconstruction with active larynx have reduced success rates.
• Laryngeal inflammation and associated factors require management before surgery and decannulation.
• Tracheostomy tube allergy is a potential cause of active larynx in pediatric patients.

Purpose of the Study:

• To investigate the role of tracheostomy component allergy in pediatric patients with active larynx.
• To evaluate the effectiveness of patch testing for identifying tracheostomy allergies.
• To determine if addressing identified allergies improves outcomes for airway reconstruction and decannulation.

Main Methods:

• Retrospective case series of pediatric patients (ages 0-18) with tracheostomies and active larynx or peristomal inflammation.
• Patients underwent patch testing for tracheostomy components.
• Clinical data including pre-testing, testing, and post-testing results were documented.

Main Results:

• Eight patients met the inclusion criteria for the study.
• 50% (4 out of 8) of patients had positive allergy tests to tracheostomy components (metal or silicone).
• All four patients with positive allergy tests experienced improvement in active larynx after tracheostomy changes, leading to successful airway reconstruction and/or decannulation.

Conclusions:

• Tracheostomy allergy should be considered in pediatric cases of idiopathic active larynx or peristomal inflammation unresponsive to standard treatments.
• Allergy testing for tracheostomy components is a low-risk, simple intervention that can reveal an identifiable cause of inflammation.
• Airway inflammation is often multifactorial, necessitating further research into pathophysiology and improved management strategies for active larynx.
