A, Waters view of the paranasal sinuses with a depressed right orbital floor fracture (white arrow) and an opacified right maxillary sinus (black arrow). B, Coronal tomogram in a different patient shows a left orbital floor fracture (white arrows) with partial left maxillary sinus opacification (black arrows).

Schüller view of the temporal bone showing a fracture (short white arrows) extending through the squamosal temporal bone, anterior to the mastoid process (long white arrow) and into the external auditory canal (double white arrows). A second fracture (short black arrows) extends through the parietal bone, into the squamosal temporal bone, and then into the skull base just anterior to the articular eminence (large black arrow) of the temporal bone.

A 20-year-old man with a lump near the angle of the mandible. Oblique view from a parotid sialogram shows distortion of secondary ducts and a “ductless” appearance (arrows) near the angle of the mandible, related to a pleomorphic adenoma of the parotid gland.

A 59-year-old man with left proptosis and negative findings on orbital x-rays and tomograms. Orbital venography was performed following percutaneous puncture of a lateral frontal vein. Frontal view from an orbital venogram (A) shows medial displacement of the anterior and midportions of the left superior ophthalmic vein (SOV) (white arrows) compared with the right (black arrows). Lateral view from an orbital venogram (B) demonstrates inferior displacement of the left SOV (open arrows) compared with the right (solid arrows). Imaging findings are suggestive of a tumor in the anterior and midportion of the orbit laterally. Biopsy of mass revealed lacrimal gland carcinoma.

Adolescent boy with epistaxis. Lateral tomogram through the right side of the nasopharynx (A) shows a nasopharyngeal mass extending into and enlarging the pterygopalatine fossa with forward bowing of the posterior wall of the maxillary antrum (short black arrow) and posterior displacement of the pterygoid process (short white arrow). The mass also extends into the anterior half of the sphenoid sinus (long white arrow) and right maxillary antrum (long black arrow). B, Lateral tomogram through the left side of the nasopharynx shows a normal pterygopalatine fossa (arrows). C, Lateral view from the right external carotid artery angiogram shows a very vascular mass (black arrows) in the nasopharynx, right pterygopalatine fossa, anterior sphenoid sinus, posterior right maxillary sinus, and posterior inferior right orbit. Supply is from the internal maxillary artery (white arrow).
