Endoscopic view on an idiopathic subglottic stenosis (Cotton-Myer grade III). The small bore tube (star) allowed for intubation of this severe stenosis. In these severe cases, HFJV could be problematic due to obstruction of the passive air backflow. This problem is tackled in FCV, allowing for good and stable ventilation.
