AbstractA 63-year-old woman developed laryngopharyngeal edema after a cervical spinal tumor resection in prone position. The tracheal tube was removed after 11 hours of general anesthesia and nasal airway was inserted because stridor was audible. Blisters were found on the skin of the anterior neck of the patient. Examinations at 3 h after the extubation suggested upper airway stenosis including stridor, increased work of breathing, oxygenation impairment, and hypercapnia. The trachea of the patient was intubated and the examination of the upper airway by inserting a fiberoptic bronchoscope through the patient's mouth revealed laryngopharyngeal edema. It was considered that the disturbance of venous and/or lymphatic flow of anterior neck due to extensive neck anteflexion during the surgery in prone position had induced the laryngopharyngeal edema; however, we could not verify the cause of the edema. The edema persisted for weeks. We conclude that we should avoid extensive neck anteflexion during surgery in prone position and it is recommended to observe the upper airway for a few hours after extubation because there could be airway obstruction due to delayed and/ or progressive laryngopharyngeal edema.
