When tested on a manikin, lifting the epiglottis with stylets as an adjunctive technique can facilitate and improve the success rate of intubation in difficult airway, such as C-L III, under direct laryngoscopy without increasing the difficulty of the intubation. Our study suggests that based on proper laryngoscope management, using the tip of the stylet-equipped ET to lift the epiglottis and following the anterior part of larynx can significantly facilitate tracheal intubation where only the epiglottis is seen.
