Computed tomography (CT) images of the neck showed narrowing of the subglottic portion of the trachea (Fig. 2).
Neck CT images taken at POD 7. Tracheal stenosis was improved but still existed at the subglottic level. The sagittal plane image demonstrates the process of the anterior wall of the trachea (arrow in the right panel). Left, transverse image of the neck. Right, sagittal image of the neck
