CT-scan: axial cut (Normal)
Bilateral air-fluid with meniscus levels in a patient with acute maxillary sinusitis. Note severely deviated nasal septum towards left side with pronounced narrowing of nasal patency anteriorly.
Generalized maxillary sinus mucosal thickening
in a patient with subacute sinusitis.
Another example of severe mucosal thickening in a patient with acute pansinusitis.
Left-sided sinusitis with blocked osteomeatal complex, deviated nasal septum, and right inferior turbinate hypertrophy. Odontogenic cause has been ruled out.
Left antral polyp (X) with early extrusion into middle meatus causing obstruction of osteomeatal complex (+).
Right maxillary sinus sinus fractures (arrow) complicating trauma and antral fluid with meniscus level (+) representing haemosinus.
Complete opacity of right frontal sinus in chronic sinusitis with nasal polyposis. Left frontal sinus mucosal thickening is shown separated by inter-frontal septum.
Left-sided frontal sinus opacity with meniscus level due to trapped infected fluid in a patient with subacute sinusitis.
Chronic sinusitis with grossly thickened frontal sinus mucosa and polyps formation.
Anterior view 3D-reconstructed CT scan of facial bones showing depressed fracture involving central forehead/glabella area secondary to blunt injury.
Lateral view 3D-reconstructed CT scan of facial bones showing similar defect more clearly.
Nasal endoscopy revealed fresh blood from right frontal recess area.
Internal carotid arteries anatomic relation in sphenoid sinus (arrows) which is of prime importance in endoscopic sphenoid sinus and transphenoidal hyphysectomy surgery.
i. Bilateral concha bullosa of middle turbinate.
ii. Low-lying anterior cranial fossa floor (Keros Type III).
iii. Deviated nasal septum to the left with compensatory inferior turbinate hypertrophy.
iv. Minimal mucosal thickening of right maxillary sinus.
Lateral opening of left concha bullosa (arrow).
Figure shows pneumatized left superior turbinate (arrow). Pansinusitis is evident bilaterally and the nasal septum is deviated to right.
Left concha bullosa with acute sinusitis.
