Which structure can be observed during a nasal examination?

The inferior turbinate is a key structure that can be directly observed during a nasal examination. During this examination, a healthcare provider typically uses a speculum or a nasal endoscope to visualize the nasal cavity. The inferior turbinate, which is situated along the lateral wall of the nasal cavity, can be easily seen and assessed for any abnormalities such as swelling, color changes, or the presence of lesions.

In contrast, while the superior turbinate is also part of the nasal anatomy, it is less accessible for direct visualization. The maxillary and frontal sinuses are located deeper within the facial structure and are typically evaluated through imaging studies rather than direct observation during a standard nasal exam. This makes the inferior turbinate the most relevant and observable structure in this context.
