“…The idea of using laryngoscopy to facilitate other airway management tools (e.g., to achieve a better glottis visualization) is not new. In numerous reports, either DL or VL has been used to assist fiberoptic bronchoscopy (FOB) in various clinical scenarios [ 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 ]. DL was also reported in combination with the fiberoptic stylet to assist in clinical and simulated difficult airway cases [ 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 ].…”
