In this study, the subjects are divided into two groups (group I: intervention group = the nasotracheal tube inserted with the bevel of the nasal tube facing the direction of the patient's head, and Group II: conventional group = the bevel of the tube toward the left side of the subject). After the endotracheal tube is introduced, a flexible endoscope is used to evaluate whether the tube is located below the inferior turbinate, i.e. in the lower pathway.
Primary outcome * incidence of tracheal tube passing through the lower pathway (beneath the inferior turbinate and immediately above the nasal floor of the nostril) Secondary outcome * intubation time * incidence of epistaxis * severity of bleeding * Resistance during Insertion of the tracheal tube

Time frame: right after completion of the intubation
intubation time

Time frame: from the start of the intubation to the completion of the intubation, which is confirmed by the appearance of end-tidal CO2 curve, up to 60 seconds
incidence and severity of epistaxis
