Which radiographic view is BEST for evaluating the maxillary sinuses?

The Waters view (occipitomental projection) is the standard radiographic projection for evaluating the maxillary sinuses. The patient tilts their chin upward 37° from the orbitomeatal line, which projects the petrous ridges below the floor of the maxillary sinuses, providing an unobstructed view. It is used to identify sinusitis, opacification, air-fluid levels, and fractures. The Caldwell view better shows frontal and ethmoid sinuses.
