A circumferential narrowing of the trachea was observed 3 cm below the vocal cords (Figure 1A) and it was not possible to advance the bronchoscope beyond the lesion. Surveillance endoscopic examination at 3 months after the procedure revealed a patent airway (Figure 1B), and the flow-volume loop was now within normal limits.
