Surgical Candidacy for Management of Laryngomalacia: A Proposed Scoring System

Identifying surgical candidacy for the management of laryngomalacia is a challenge.

To develop a simple scoring system for surgical candidacy in laryngomalacia.

Eighteen years retrospective observational study of children with laryngomalacia (LM) clinically categorized into mild, moderate and severe LM and were analyzed for surgical candidacy.

There were 113 children (age ranging from 5 days to 14 months), 44% being mild, 30% moderate and 26% severe LM. None in mild, 32% in moderate, and all in severe LM had surgical intervention. Presence of stridor on feeding or crying and isolated type 1 or type 2 LM on laryngoscopy were significant indicators for conservative treatment (p-< 0.0001). Moderate failure to thrive, retraction at rest/sleep, with low oxygen saturation while feeding/at rest were significantly higher in both moderate and severe groups with laryngoscopic evidence of combined type 1 and 2 in moderate LM (p < 00,001). Aspiration pneumonia, hospitalization, pectus and mean pulmonary arterial pressure of more than 25 mmHg with laryngoscopic findings of all three combined types were significantly higher in severe LM (p < 0.0001).A simple scoring system was then developed and it revealed that a score of 10 or more required surgical intervention.

A clinical scoring system is being reported for the first time in medical literature to identify 'the difficult to treat' subset within moderate laryngomalacia category simplifying decision making in its management for otolaryngologists and pediatricians as well as a referral criterion for pediatric otolaryngologists' services.
