Preoperative bronchoscopic findings of thyroid carcinoma with tracheal invasion wereexamined and compared with the histopathological findings. Tracheal sleeve resectionwas performed in 20 cases. The bronchoscopic findings were classified into 5 types:confirmed tumor in the tracheal lumen (5 cases), extramural compression of the tracheaplus mucosal change (9 cases), extramural compression of the trachea (2 cases), mucosalchanges only (3 cases), normal findings (1 case). Pathological findings revealed that theextent of invasion in the tracheal wall varied according to each of the above bronchoscopictypes. The number of tracheal rings with adventitial invasion averaged 0.8 (maximum2) more than preoperative bronchoscopic findings of the number of tracheal ringswith mucosal invasion. This study demonstrated the necessity of resective 2 more trachealrings than is indicated by the bronchoscopic findings.
