The anesthesia and surgical procedures from the time the patient enters the operating room to discharge from the recovery room are identical to those used in conventional airway surgeries performed under general anesthesia with Transnasal Humidified Rapid-Insufflation Ventilatory Exchange (THRIVE). The time point at which rescue ventilation is required due to a drop in oxygen saturation below 92% during anesthesia will be recorded, and the predictive factors for this event will be investigated.
