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.

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

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.
