MAXILLOFACIAL CT
History: Postnasal drip, recurrent sinusitis.
Technique: Multislice volume acquisition axial sections of the maxillofacial
region including the paranasal sinuses and orbits were obtained. Multiplanar
sagittal and coronal images also obtained.
Findings: There is complete opacification of the left maxillary sinus with focal
defect in its medial wall and obliterated left ostiomeatal unit. There is also
partial opacification and mucosal thickening of the left ethmoid and adjacent
frontal sinuses. Associated left maxillary/ethmoid sinus retention cyst/polyp
suspected. The sphenoid, right maxillary and right ethmoid sinuses are clear and
the right ostiomeatal unit is patent. There is leftward nasal septum deviation.
The bilateral zygomatic arches, pterygoid plates, nasal bones, walls of the
remaining paranasal sinuses and both orbits are otherwise intact. The bilateral
optic globes are unremarkable and there is no intraorbital fluid collection.
IMPRESSION: Paranasal sinus disease involving the left maxillary, left ethmoid
and adjacent frontal sinuses as described.
Leftward nasal septum deviation.
