Lund-Mackay score calculator for chronic rhinosinusitis

Notes

About the score

• The Lund-Mackay score first assigns each side of all sinuses a score of:
  • 0 – normal
  • 1 – partial opacification
  • 2 – complete opacification

• The ostiomeatal complex is graded differently:
  • 0 – not obstructed
  • 2 – obstructed

• The maximum of the score is 24

• Despite its intentional simplicity the Lund-Mackay score was found to correlate well with symptoms and other markers of disease severity

• It was also found that preoperative Lund-Mackay scores of patients prior to sinus surgery correlate with postoperative quality of life
