SNOW
A modification which includes the Miller spatula and the Wis-Foregger (Wisconsin modification) flange to reduce trauma during intubation, especially for use with the Sanders tube. Curving back from the distal end, it provides a convenient visual field.

SIKER MIRROR
For laryngoscopy of patients with anatomical variations which make intubation with conventional blades difficult or impossible. The basic portion of the blade makes an angle of 135° with a stainless steel mirror located at that angle on the flange facing the spatula. The distal portion of the blade is three inches long. Because the mirror inverts the reflected image, the operator should exercise caution until familiar with its use. A curved stylette is recommended for use with the Siker blade. Placing the blade in a warm water bath for ten minutes before use will avoid any mirror fogging problems.

WHITEHEAD MODIFICATION OF WISCONSIN
A modification of the Wisconsin blade with a reduced flange to increase visualization, facilitate intubation and reduce possibility of damage to the incisors.
