A COMPARATIVE STUDY OF LUND-MACKAY SCORING AND POSE SCORING IN CHRONIC RHINO-SINUSITIS PATIENTS.

INTRODUCTION: To compare preoperative Computed Tomography scan ndings of Para nasal sinuses using Lund-Mackay scoring and intra operative Functional endoscopic sinus surgery ndings in patients with Chronic Rhino-sinusitis using the POSE scoring and to correlate maximum scores obtained in Perioperative sinus endoscopy (POSE) scoring system and Lund-Mackay scoring system. MATERIALS AND METHODS:AProspective study was done for 1 year on 48 patients attending outpatient department of ENT, Sri Siddhartha Medical College aged between 18-60 years, who were clinically diagnosed to have Chronic Rhino-sinusitis, underwent pre-operative CT scan of nose and paranasal sinuses and thereafter FESS were enrolled for the study after obtaining the due consent. RESULTS: From our study group of 48 patients who underwent endoscopic sinus surgery for CRS, the minimum value of Lund-MacKay Scoring was 3 whereas the maximum was 18 (maximum obtainable is 24) with a mean value of 12.02 and standard deviation of 3.987. The minimum POSE Score obtained was 7 and the maximum POSE Score obtained was 37 (maximum obtainable being 40), with a mean value of 16.31 and standard deviation of 5.095. CONCLUSION: Pre operative CT scan combined with per operative endoscopy ndings has made the approach to Chronic rhinosinusitis more specic, rational and accurate. The results of our study highlights that CT scan is an important investigation tool to detect Chronic rhinosinusitis . CT scan has very much emerged as the gold standard in preoperative diagnosis and allows for accurate patient selection for FESS. In our study, POSE Scoring has shown a good correlation with Lund MacKay scoring system
