Which imaging view is best for demonstrating maxillary sinusitis?

The Waters view is considered the best imaging technique for demonstrating maxillary sinusitis due to its specific orientation that allows for optimal visualization of the maxillary sinuses. In this view, the patient's orbitomeatal line (OML) is perpendicular to the film or detector, which positions the maxillary sinuses in a way that they can be seen clearly.

By utilizing the Waters view, the anatomical structures of the maxillary sinuses are projected in their largest dimension, minimizing overlying structures, and enhancing the ability to identify fluid levels, mucosal thickening, or other signs of sinusitis. This makes it easier to assess for the presence of conditions such as sinus infections, blockages, or neoplastic processes possibly affecting the maxillary sinuses.

Other views may capture sinus anatomy, but they do not provide the same clarity and detail for the maxillary sinuses specifically. For example, the frontal view focuses more on the frontal sinuses, while the lateral view offers a side perspective that can be less effective for directly visualizing the maxillary sinuses. The submentovertex view is primarily used for visualizing the sphenoid sinus and the base of the skull rather than the maxillary sinuses. Thus, the Waters view is the best
