Fingers Hook Technique to Facilitate Nasotracheal Intubation

It is necessary to adequately exposure of glottis during naso-tracheal intubation using video-stylet. However, inadequate upward epiglottis or over-elevation of arytenoids all inhibit the tube tip smoothly into trachea. Therefore, the study is to investigate either jaw thrust or fingers-hook technique is advantages of nasotracheal intubation.
