Coronal imaging through the paranasal sinuses is typically performed with the imaging plane:

Coronal imaging through the paranasal sinuses is performed with the imaging plane perpendicular to the hard palate to ensure optimal visualization of the sinus cavities and associated structures. This orientation allows for a comprehensive view of the frontal, maxillary, ethmoid, and sphenoid sinuses, which is critical for diagnosing conditions such as sinusitis, tumor presence, and anatomical variations.

When the imaging plane is perpendicular to the hard palate, it aligns well with the natural anatomy of the sinus regions. This perspective provides a clear delineation of the sinuses relative to other craniofacial structures, enhancing diagnostic accuracy.

In contrast, imaging that is parallel to the hard palate or aligned with the mid-sagittal plane would not capture the full extent of the sinuses effectively. The angle alignment would also introduce distortion in visualizing the complex sinus anatomy, which is crucial for both diagnosis and treatment planning. Therefore, the perpendicular orientation is essential for clear, accurate imaging of the paranasal sinuses.
