Laryngomalacia: a proposed classification form

Area of Science:

• Pediatric Otolaryngology
• Pediatric Pulmonology
• Medical Informatics

Background:

• Laryngomalacia is a frequent cause of stridor in children, presenting with varied severity.
• Current literature lacks standardized methods to correlate clinical presentation, endoscopic findings, treatment, and outcomes.
• Effective treatment selection requires patient stratification based on disease severity predictors.

Purpose of the Study:

• To develop and pilot a classification form for laryngomalacia.
• To stratify patients based on historical (SWAN mnemonic) and anatomical factors.
• To enable statistical analysis of treatment efficacy and outcomes based on initial presentation.

Main Methods:

• A novel classification form was designed incorporating historical factors (stridor severity, weight gain, age, neurologic status - SWAN) and anatomical site of collapse.
• Endoscopic findings, including signs of gastroesophageal reflux disease (GERD) or aspiration, were documented.
• A pilot study classified ten pediatric patients (age range: 1 day to 19 months) using the form.

Main Results:

• The classification form was found to be easy to use and effective in organizing the heterogeneous presentations of laryngomalacia.
• The pilot study demonstrated the practical application of the form in both clinic and operating room settings.
• The tool facilitated the organization of patient data, highlighting the disorder's variability.

Conclusions:

• The proposed classification form provides a structured approach to assessing laryngomalacia.
• Wider institutional adoption can facilitate the accumulation of data for robust statistical analysis.
• This stratification is crucial for optimizing treatment strategies and improving patient outcomes in laryngomalacia.
