    Objective: The Lund Mackay Postoperative Endoscopy Score (LMES) for chronic rhinosinusitis (CRS) is a poor measure of the patient experience. A proposed Modi!ed Lund Mackay Postoperative Endoscopy Score (MLMES) aims to better describe the inflammatory burden in CRS. Methods: A prospective study on CRS patients having endoscopic sinus surgery (ESS) was conducted. Endoscopy was recorded at the 6th and the 12th week post-op. The MLMES recorded changes in mucosa, mucus and purulence for each of the maxillary, ethmoid, sphenoid, frontal sinuses and olfactory fossa in post-ESS cavities. The correlation between MLMES and visual analogue scale of total rhinosinusitis symptoms, global anchor score of nasal function, Sino-Nasal Outcome Test 22 (SNOT-22) and nasal symptom score was analyzed. The inter-observer reliability, intra-observer reliability and correlation between the change in MLMES and in subjective measures were also investigated. Results: Thirty patients were assessed. The MLMES signi!cantly correlated with visual analogue scale, SNOT-22, global anchor and nasal symptom score. The change in MLMES correlated with the change in SNOT-22 and nasal symptom score. The inter-observer and intra-observer reliability were excellent. Conclusion: Objectives measurements for post-ESS patients can be reconsidered to represent the cumulative inflammatory burden of all sinuses. The proposed MLMES represents total sinus inflammatory burden and correlates well with patient reported outcome measures.
