In total, 137 patients were screened between October 2020 and June 2021. Of these, 18 patients did not meet the inclusion criteria and 5 patients declined to participate. The remaining 114 patients were randomly allocated to the NG group (57 patients) or the SC group (57 patients) for statistical analysis (There was no difference between the two groups in terms of patient demographics, pre-operative airway evaluations, and intubation variables (The total intubation time was significantly shorter in the SC group than in the NG group (45.3 ± 10.0 s vs. 52.4 ± 9.7 s, When the nasotracheal tube was passing through the nose, the number of preformed nasotracheal tube manipulations, navigability, and tube rotation did not differ significantly between the two groups. Regarding the passage of the nasotracheal tube through the nasal cavity into the pharynx, there were no differences between the two groups in the degree of nasal bleeding through direct laryngoscopy, the use of Magill forceps, or the total number of intubation attempts. Endotracheal intubation was successful in all patients, and there was no difference between the two groups in the direction of the tube in the nasal cavity (upper pathway or lower pathway) or the total duration of anesthesia. In the PACU, the nasal pain score and persistent epistaxis were similar between the two groups. A comparison of the outcomes between the two groups is shown in For the stress relaxation test, the force required to return the guiding devices to the original state was greater for the suction catheter (9.01592 MPa) than that for the nasogastric tube (4.07734 MPa) (Comparing the force required to remove the aids, the removal of the NG tube required more force than the removal of the suction catheter (
