Airway management during the laryngoscopic surgery for the benign laryngeal obstructive disease.

The airway management and anesthesia maintenance during the laryngoscopic surgery is essential for a safe operation. For the benign laryngeal obstructive disease such as a large mass or a foreign body of the upper airway, it is difficult to secure the airway. Sometimes they might be hazardous and potentially lethal. We present two cases of a large laryngeal polyp and a laryngeal foreign body of pressthrough-package (PTP). They were successfully operated on with laryngomicrosurgery under neuroleptanalgesia (NLA) without intubation. The choice of the operation and airway management were discussed.
