Figure 2 Cases 3 to 6. A: Preoperative fiberoptic bronchoscopy (FB) showed that the left lower lobe bronchus (above) was blocked by granulation 10 d after injury in case 3; B: Preoperative FB showed deformed right lower bronchus and collapsed cartilage ring in case 4; C: Preoperative computed tomography (CT) image showing pneumomediastinum and right pneumothorax in case 5; D: FB showed deformed and closed right main bronchus in case 5; E and F: Preoperative CT images showing an interrupted right main bronchus in case 6.

Figure 4 Case 8. A: Computed tomography (CT) image showing a deformed left main bronchus, discontinuous with air around bronchi, besides the right pneumothorax and subcutaneous emphysema at admission; B and C: After 50 d, CT showed left atelectasis and the interrupted left main bronchus; D and E: Intraoperative images showing transected bronchus and scar excision followed by end-to-end anastomosis; F: Postoperative CT image showing distended left lung, and unblocked main bronchus and lobar bronchi.

Figure 5 Case 9. A: Fiberoptic bronchoscopy (FB) showed deformed and collapsed left main bronchus the day after injury; B: Intraoperative image showing transected bronchus, debridement, and end-to-end anastomosis; C: FB showed lumen stenosis with sutures across 3 wk after surgery; D: FB failed to relieve the stenosis and repeated atelectasis; E: Reoperation was performed for resection of stenosis and anastomosis 3 years later, and postoperative computed tomography shows distended left lung.
