Abstract

The study was carried out to correlate the inflammatory markers (NLR, ELR, PLR) before and after endoscopic sinus surgery and their role in the prediction of recurrent nasal polyps. This was a hospital-based observational study carried out the 43 patients, aged between 18-45 years, admitted to the department of ENT with CRSwNP and underwent endoscopic sinus surgery. NLR, ELR & PLR values were compared for each patient and calculated from complete blood counts taken before and after surgery follow-up period at post-op 1st week, 3rd week, 3rd month, and 6th month. In our study, 12 out of 43 patients who underwent ESS showed recurrence. The mean value of ELR was higher in the pre-operative and post-operative 1st week in recurrent nasal polyp patients than in non-recurrent nasal polyps. (p-value < 0.05) but there were no significant changes in ELR values in subsequent follow-ups. There were no significant changes in NLR & PLR in the pre-operative and post-operative periods. Although recurrence was common in CRSwNP after endoscopic sinus surgery. Inflammatory markers could be used to predict the chances of recurrence. In our study, ELR is a better parameter than NLR and PLR in the assessment of the chance of recurrence.
