Brief summary

to compare either using conventional jaw thrust technique or with a novel fingers-hook technique to facilitate video-stylet assisted nasotracheal intubation

Detailed description

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.
