The Miller Laryngoscope Blade . . . The most popular of the straight types. The side of
the flange is reduced to minimize trauma and the curve at the beak or tip is extended to
improve lifting of the epiglottis. These improvements facilitate greater exposure of the
larynx in difficult-to-intubate patients.
The Macintosh Laryngoscope Blade . . . The Macintosh is the predominate model of
the curved blade types. During laryngoscopy, the tip or beak of the blade is compressed
into the angle formed by the base of the tongue and the epiglottis, indirectly raising the
epiglottis. Some sizes are available flangeless. Also available is a die-stamped or
one-piece construction blade with a slightly expanded flange
