Sinus Scoring Systems

Lund-MacKay scoring system

Left and right sides scored independently.

Maxillary (0, 1, 2)

Anterior ethmoidal (0, 1, 2)

Posterior ethmoidal (0, 1, 2)

Sphenoidal (0, 1, 2)

Frontal (0, 1, 2)

Ostiomeatal complex (0 or 2 only)*

 

*Key: For all sinus systems, except the ostiomeatal complex:

0 = no abnormalities; 1 = partial opacification; 2 = total opacification

For the ostiomeatal complex: 0 = not occluded; 2 = occluded

Harvard System Staging

Stage 0: Normal (< 2 mm mucosal thickening on any sinus wall)

Stage 1: All unilateral disease or anatomic abnormality

Stage II: Bilateral disease limited to ethmoidal or maxillary sinuses

Stage III: Bilateral disease with involvement of at least one sphenoidal or frontal sinus

Stage IV: Pansinusitis
