The miller laryngoscope blade is a straight blade that is used to view the vocal cords by directly lifting the epiglottis. It has a useful application in 'floppy' airways, making it popular in pediatric anesthesia. Miller blades have curved  tip. While Macintosh laryngoscope blade are curved blades that is used in adult anesthesia. The miller laryngoscope blades are inserted into the vallecula, just anterior to the epiglottis, which is literally turned out of the visual axis to reveal the airway opening.
