Fiberoptic bronchoscopy in thyroid carcinoma with tracheal invasion.

Preoperative bronchoscopic findings of thyroid carcinoma with tracheal invasion were examined and compared with the histopathological findings. Tracheal sleeve resection was performed in 20 cases. The bronchoscopic findings were classified into 5 types: confirmed tumor in the tracheal lumen (5 cases), extramural compression of the trachea plus mucosal change (9 cases), extramural compression of the trachea (2 cases), mucosal changes only (3 cases), normal findings (1 case).
