Abstract:
The occurrences of pneumothorax and pneumomediastinum are rare, but considered to be potentially life-threatening conditions in patients undergoing functional endoscopic sinus surgery under general anesthesia. Tracheobronchial rupture may results in serious complications, such as pneumothorax and pneumomediastinum. It may occur accidentally by endotracheal tube when the patient's neck is flexed or extended. We report the case of a 48-year-old female patient who developed massive subcutaneous emphysema, pneumothorax, pneumomediastinum and pneumoperitoneum seven hours after functional endoscopic sinus surgery under general anesthesia.
