FLANGE-LESS MAC (BIZZARRI-GIUFFRIDA) A modification of the MacIntosh blade with the upper flange removed. This blade is especially well suited for use in patients with a limited mouth opening, prominent incisors, receding mandible, short thick neck, or having the larynx in an extreme anterior anatomical position. The absence of the flange greatly reduces the chance of trauma during laryngoscopy. Blade is made of surgical stainless steel.
