NPS (Endoscopic Nasal Polyp Score)1,3
Right Nostril | 0 | 1 | 2 | 3 | 4 |
Left Nostril | 0 | 1 | 2 | 3 | 4 |
Total score
*The maximum score is 8 (4 points per nasal cavity).
Polyp size / location | ![]() | ![]() | ![]() | ![]() | ![]() |
Anatomical description | No polyp. | Presence of small polyps in the middle meatus not reaching below the inferior border of the middle turbinate. | Polyps reaching below the inferior border of the middle turbinate | Large polyps reaching the lower border of the inferior turbinate or polyps medial to the middle turbinate. | Large polyps causing complete obstruction of the inferior nasal cavity. |
Lund-Mackay CT Scoring System1,4,5

Sinus system | Left | Right | Total score |
Maxillary | |||
Anterior ethmoidal | |||
Posterior ethmoidal | |||
Sphenoidal | |||
Frontal | |||
Osteomeatal complex | |||
Total score |
GRADING
0 | = | Absence (No mucosal thickening) |
1 | = | Partial opacification |
2 | = | Complete opacification |
The Osteomeatal Complex (OC) is graded separately as 0 = not occluded or 2 = occluded, deriving a maximum score of 12 per side.

8-20 inclusive (Mild)
>20-50 (Moderate)
>50 (Severe)
*The range of the SNOT-22 score is 0 to 110, where lower scores indicate less impact.
