The graphic patterns of TBFVL in cases of laryngomalacia are shown in Table 3. Pattern 3 (normal expiratory limb and fluttered inspiratory limb) was the most common (present in 46.4%) pattern in children with isolated laryngomalacia. In 21 (pattern three plus pattern 4) out of 28 isolated laryngomalacia cases, the graphic pattern was consistent with a fluttered inspiratory limb.
