Videolaryngoscope provide better view of the larynx. This better view could improve the navigation of endotracheal tube in nasotracheal intubation. Contrast to the improved result in adult, one previous report using Glidescope in children did not show better performance than direct laryngoscope. The aim of this study is to compare the performance of McGrath, Pentax and Macintosh laryngoscope for nasotracheal intubation in children.
