Diagrammatic coronal section through the mid-nose showing the two main pathways for nasal intubation. The lower pathway lies along the floor of the nose, underneath the inferior turbinate. The upper pathway lies above the inferior turbinate, below the middle turbinate. Migration of tubes between pathways is usually prevented by the medial border of the inferior turbinate, which approximates to the nasal septum.

3. Fig 2
Endoscopic images of right nostrils. The endoscopist is standing behind the head of the supine patient, so that the floor of the nose is at the top of the visual field. (a) The endoscope is inserted above the tube and advanced into the nostril. The tube lies in the lower pathway underneath the inferior turbinate, against the base of the septum. (b) The endoscope is inserted below the tube. The tube lies in the upper pathway superomedial to the inferior turbinate. (c) The endoscope is inserted above the tube. The tube is in the upper pathway, compressing the middle turbinate.
