​Twenty-Six Radiographic Areas To Give Particular Attention
For Evaluating The Paranasal Sinuses

Bony Abnormalities

1. Agger nasi cells presence AND obstructive potential
2. Concha bullae ofthe middle turbinates
3. Paradoxical curve of the middle turbinates
4. Deviated nasal septum
5. Retracted uncinate process/small infundibulum
6. Pneumatized uncinate process
7. Infraorbital ethmoid cells (Haller cellsO
8. Hypoplasia ofthe maxillary sinus
9. Supraorbital ethmoid cells
10. Abnormal frontal sinuses
11. Abnormal bullae ethmoidalis
12. Depth oflaterallamellae ofthe cribriform
13. Concha bullae ofthe superior turbinates
14. Contact points
15. Bony abnormalities within the sphenoid sinus (carotid artery, optic nerve, pneumatized pterygoid & clinoid)
16. Craniofacial anomalies or asymmetry

Mucosal abnormalities:

1. Osteomeatal complex
2. Maxillary sinus
3. Accessory ostia to the maxillary sinus ( fontanelle)
4. Anterior ethmoids
5. Posterior ethmoids
6. Frontal recess
7. Frontal sinus
8. Sphenoid sinus
9. Nasal passages
10. Adenoids
