Abstract
A 77-year-old man was scheduled to undergo a cervical lymph node biopsy under general anesthesia. Although awake, nasotracheal fiberoptic intubation was initially planned because of an anticipated difficult airway, the attempt was unsuccessful. Orotracheal intubation was subsequently performed under direct laryngoscopy without difficulty. After initiating positive pressure mechanical ventilation, subcutaneous and mediastinal emphysema developed. The cause of this emphysema was considered to be tracheal perforation after an unsuccessful attempt at fiberoptic tracheal intubation.
