Lateral view xray of paranasal sinuses is not done regularly though all sinuses are visible

lateral view xray of paranasal sinuses is not done regularly though all sinuses are visible

Waters view xray is most commonly done … (though posterior ethmoid is not visible)

Why?

Most of the times, anterior group of sinuses are involved in causing chronic rhinosinusitis., and maxillary is the one involved mostly…
Waters view shows these sinuses clearly…
U can also see both sides in a single x-ray…
