TBFVL curve; D-Pattern 4, Inspiratory limb FLUTTERED and expiratory limb
FLATTENED; E-Pattern 5, Early expiratory peak with the concave
expiratory limb; F. Representative TBFVL image of subglottic stenosis
TBFVL parameters in different bronchoscopy diagnoses-The TBFVL parameters in children with laryngomalacia compared to
controls are shown in Supplementary Table S1. There was a significantly
high ratio of inspiration to expiration time in children with isolated
laryngomalacia. The remaining TBFVL parameters were similar in children
with isolated laryngomalacia and controls. The TBFVL parameters in
various types of airway anomaly (other than laryngomalacia) and controls
are shown in Supplementary Table S2.
