case_images: Chest computed tomography 1.5 months previously. (a) The anteroposterior diameter of the trachea at 3 cm away from the glottis was 10.3 mm. (b) The anteroposterior diameter of the trachea at 6 cm away from the glottis was 9.8 mm. (c) The anteroposterior diameter of the tracheal bifurcation at 9 cm away from the glottis was 5.8 mm.

case_images: However, chest computed tomography (CT) 1.5 months previously showed tracheal stenosis that had flattened the lumen (Figure 1).
case_images: Bronchoscopy after induction of anesthesia revealed tracheal stenosis that gradually became more severe from under the glottis.

case_images: Tokyo, Japan), and bronchoscopic examination was performed through the breathing channel of the i-gel. Tracheal stenosis that gradually became more severe from under the glottis was revealed (Figure 2). Therefore, a tracheal tube of 6-mm ID was inserted using the Airway Scope.
