ABSTRACT
Tracheobronchopathia osteochondroplastica (TO) is a rare dysplastic disease of the trachea characterized by cartilaginous or bony nodules in the tracheobronchial lumen. Rigid video-stylet is an intubating device that provides favorable conditions even in the difficult cases. In this report, we describe a successful airway management using the rigid video-stylet in a 62-year-old man with unanticipated difficult intubation later diagnosed for TO. He was planned for elective percutaneous nephrolithotomy under general anesthesia. He was healthy without any airway symptoms. With the rigid video-stylet, we not only performed successful tracheal intubation but also examined endotracheal lumen simultaneously. Using the rigid video-stylet, we noticed multiple whitish projecting nodules in the trachea, which were the typical findings for TO.
