Figure 3: Representative images of each type of IPFT pattern and subglottic stenosis; A-Pattern1, Normal TBFVL graphic curve; B-Pattern 2, Normal inspiratory limb and FLATTENED expiratory limb of TBFVL curve; C-Pattern 3, Normal expiratory limb and FLUTTERED inspiratory limb of 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.
