We included all 34 children under 2 years old with endoscpically confirmed laryngomalacia without prior documentation of the diagnosis. Results: 34 children had a confirmed diagnosis of laryngomalacia and were thus included (1.8:1 male to female sex ratio; mean age, 3 months, age range, 0-6 months). Twenty- three children (67,6%) presented with stridor, 34 (100%) with pulmonary rales, 33 (97,1%) with using accessory respiratory muscles. Type 1 laryngomalacia was the most commoly encountered (29,4%). Most with severe laryngomalacia (52,9%) needed medical treatments in our study. GERD and pneumonia are theo two common comorbidities in our study. Medical comorbidites were associated with severe laryngomalacia.
