Final answer:
On a lateral view of the skull, the frontal and maxillary sinuses can typically be visualized, and possibly the sphenoid sinus and ethmoid air cells depending on the imaging technique and individual anatomy.
Step-by-step explanation:
The sinuses visualized on a lateral view of the skull include several of the paranasal sinuses. Specifically, the frontal sinus located in the frontal bone above the eyebrows, and the maxillary sinuses located in the right and left maxillary bones below the orbits, can be seen. It is also possible to visualize the sphenoid sinus located in the body of the sphenoid bone, which lies under the sella turcica. Although not always clearly distinguishable in a standard lateral view, the ethmoid air cells, which are multiple small spaces in the right and left sides of the ethmoid bone, might also be visible depending on the imaging technique and the individual's anatomy.
