CORELATION OF OUTCOMES FOLLOWING BILATERAL ENDOSCOPIC SINUS SURGERY USING SNOT-10 AND LUND- KENNEDY SCORE

Abstract

Objectives: To compare pre-operative and post-operative Sinonasal outcome test-10 (SNOT-10) score and to evaluate the co-relation between post-operative Lund-Kennedy and SNOT-10 score following bilateral endoscopic sinus surgery.

Materials and Methods: This was a prospective, observational study conducted in Ganeshman Singh Memorial Academy of ENT-Head & Neck Studies, Tribhuvan University Teaching Hospital, Kathmandu, Nepal from August 2016 to August 2017. Thirty one cases of chronic rhinosinusitis with or without nasal polyposis were included in the study. SNOT-10 was used to record the pre and postoperative scores and compared using paired t-test. Lund Kennedy score was used postoperatively. Both score system were correlated using Karl Pearson correlation coefficient.

Results: Our study could not yield statistically significant corelation between post- operative Lund-Kennedy and SNOT-10 score. However, there was a significant improvement in post-operative SNOT-10 score compared to pre- operative score.

Conclusion: Various emotional and psychological factors may affect the patient reported symptom score which might be the reason for this failure of co-relation. Thus, a combined symptomatic and endoscopic scoring system should be developed to assess the outcomes following endoscopic sinus surgery.
