[A model for training in laryngeal exposure].

Laryngeal exposure, applying forward and upward force by laryngoscope after placement of the blade head at the vallecula, is most difficult for begginers to learn in tracheal intubation. It is not so easy to practice at home as the laryngoscope is shaped to lift the tongue upward only. Beginners must establish a proper image of moving the left hand for laryngeal exposure and must be trained in this technique prior to tracheal intubation of patients. Not only begginers but also veterans may struggle with intubating mannequins. The author made a simple model for training laryngeal exposure by Macintosh blade. It has two resembling parts of epiglottis with hyoepiglottic ligament and jaw. It is constructed so that the epiglottis-like part can be elevated only when force through the blade is applied in an correct direction upon it. In this model, beginner can move laryngoscope easily in many ways by his hand before achieving good laryngeal exposure.
