A Case of Tracheopathia Osteoplastica Managed with Electrical Drill / 대한이비인후과학회지

Tracheopathia osteoplastica (TO) is a rare clinical and pathologic benign condition that causes irregularity, narrowing and rigidity of the trachea and the main bronchi, characterized by multiple submucosal cartilaginous and osseous nodules of various sizes lining the upper respiratory tract. The treatment of TO diagnosed with CT and bronchoscopic biopsy is mostly supportive, and sometimes laser vaporization is used. We experienced a case of TO with severe obstructed airway that was treated by drilling.
