During nasal intubation, the inferior turbinate is at greater risk of trauma than is the middle turbinate because it is closer to the nasotracheal tube. (6) Preexisting intranasal abnormalities, such as an enlarged inferior turbinate or a septal spur, increase the risk of middle turbinate trauma when they cause the nasotracheal tube to be redirected higher into the nasal cavity.
