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 specic, 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
