 An intubating stylet is a malleable metal wire designed to be inserted into the endotracheal tube to make the tube conform better to the upper airway anatomy of the specific individual . This aid is commonly used with a difficult laryngoscopy . Just as with laryngoscope blades , there are also several types of available stylets , such as the Verathon Stylet , which is specifically designed to follow the 60 ° blade angle of the GlideScope video laryngoscope .
