Chronic sinusitis refers to ongoing long term sinus infection-inflammation that often develops secondary to a prolonged ~~to refractory~~ /refractory acute sinus infection.

Epidemiology

It most commonly affects young to middle ~~aged~~-aged adults but can uncommonly affect children.

Pathology

Aetiology

deviated nasal septum
sinonasal polyposis
sinus anatomy distortion that may be congenital or from prior trauma
allergic reactions
- fungal sinusitis

Radiographic features

CT

A characteristic feature on CT sinuses is sclerotic thickened bone involving the sinus wall from a prolonged ~~muco-periosteal~~mucoperiosteal reaction. Intrasinus calcification may be present. The presence of opacification is not a good distinguisher from an acute sinus infection.
