Summary

Participants are randomly assigned to two groups: one group undergoes nasotracheal intubation using a videolaryngoscope, while the other group undergoes nasotracheal intubation using a flexible bronchoscope. The primary outcome is the first-attempt success rate, assessed at the time of tracheal tube placement. Additional outcomes include the degree of subglottic injury upon extubation, and the incidence and severity of sore throat and hoarseness at 1 hour and 24 hours postoperatively, as well as overall intubation success rates.

Conditions

• Intubation Complication

Interventions

Type	Name	Description
DEVICE	Macintosh videolaryngoscope	Used to perform nasotracheal intubation under general anesthesia. The Macintosh videolaryngoscope is introduced orally to visualize the glottis, and a preformed nasotracheal tube is inserted through the nostril.
DEVICE	Flexible bronchoscope	Used to perform nasotracheal intubation under general anesthesia. The bronchoscope is inserted through a lubricated nasotracheal tube and advanced into the trachea.
