Figures
- Figure 1
Chest radiography, posteroanterior and lateral views, showed normal findings.
- Figure 2
Flow-volume loop showed a decrease in inspiratory and expiratory flow suggestive of fixed extrathoracic airway obstruction.
- Figure 3
Tracheal web was seen below the vocal cords on flexible bronchoscopy.
- Figure 4
Resection of tracheal web performed with successful endobronchial argon plasma coagulation dilation.
