Main findings on your CT PNS report

1. Sinusitis, mainly on the right
   • Extensive mucosal thickening in the right maxillary sinus.
   • Mild thickening in the left maxillary sinus, both ethmoid air cells, and sphenoid sinuses.
   • This indicates inflammation/swelling of the sinus lining, consistent with multisinusitis.
2. Blocked sinus drainage pathways
   • The osteomeatal complexes (OMUs), including both maxillary sinus openings and fronto-ethmoid recesses, are blocked by mucosal swelling.
   • This can impair mucus drainage and contribute to facial pressure, nasal blockage, post-nasal drip, reduced smell, or recurrent sinus infections.
3. Deviated nasal septum with a bony spur
   • The nasal septum bends toward the right, with a bony spur.
   • This can contribute to one-sided nasal obstruction and may worsen sinus ventilation or symptoms in some people. A recent systematic review examines the association between septal deviation and rhinosinusitis, but a deviated septum alone does not automatically mean surgery is needed (systematic review, PMID 41276970).
4. Left inferior turbinate hypertrophy
   • The left lower nasal turbinate is enlarged. Turbinates normally warm and filter air, but enlargement can cause nasal blockage, often with allergy or chronic nasal inflammation.

Reassuring findings

• No destructive bone lesion: the sinus bony walls are intact.
• The spheno-ethmoid recesses appear normal.
• Optic nerve type II and Keros type II olfactory fossa are normal anatomical variants. They mainly matter as information for an ENT surgeon if endoscopic sinus surgery is ever considered. They do not themselves cause symptoms.
