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.
