Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Background: Nasotracheal intubation can lead to severe complications like epistaxis with excessive bleeding. The advancement difficulty of the tube faced during nasal intubation is one of the fundamental causes of this condition. The present study aimed to evaluate the effectiveness of Computed tomography-guided nasotracheal intubation in predicting tube advancement difficulty and preventing epistaxis.

Material and Methods: 60 maxillofacial surgery patients were included in the study. The space where the tube will be passed in the internal nasal valve region was measured horizontally (distance between inferior concha and septum) and vertically (distance between inferior concha and hard palate) by Computed Tomography. The patients were divided into two groups, 'easy' (n=28) or 'difficult' (n=32), according to the effort required to advance the tube through the nasal passage.

ROC analysis was performed, and cut-off values were determined to reveal the distance values at which difficulty may be experienced while advancing the tube. The cut-off values were 1.09 cm and 0.39 cm for the vertically and horizontally distances, respectively.

computed tomography-guided nasotracheal intubation

Before intubation, the lower part of the nasal valve region, aka the narrowest area of the nasal passage, was measured by calculating the distance between the anterior border of the inferior concha and the septal cartilage
