When examining the nasal cavity, what structure is typically not visible?

When examining the nasal cavity, the superior turbinate is typically not visible to the clinician during a standard examination. The superior turbinate is positioned high in the nasal cavity, often obscured by the middle turbinate and the overall anatomy of the nasal passages.

In contrast, structures such as the inferior turbinate and middle turbinate are located lower in the nasal cavity and are easier to visualize during examination. The vestibule, which is the front part of the nasal cavity just inside the nostrils, is also visible upon inspection.

The superior turbinate's location and its smaller size compared to the middle and inferior turbinates make it less accessible during routine examination, necessitating more advanced imaging techniques or procedures to properly assess it when needed.
