Answer

In 1993, Lund and Mackay proposed the following three-point system for staging nasal polyps according to endoscopic appearance [12, 13] :

  • 0 - No polyposis
  • 1 - Polyps confined to the middle meatus
  • 2 - Polyps beyond the middle meatus

Subsequently, this system was modified as follows [14, 15] :

  • 0 - No polyps
  • 1 - Polyps restricted to the middle meatus
  • 2 - Polyps extending below the middle turbinate
  • 3 - Massive polyposis, occluding the entire nasal cavity
