were kept in study group, and 45 patients without any intervention were the control. Sino-nasal outcome test (SNOT-10), was measured and graded from 0 to 3, depending upon the severity, Z test for mean was used as a statistical tool. R e s u l t s : Total 135 (90 cases and 45 control) patients with deviated nasal septum were included. The total mean SNOT score improvement was from 7.73 (S.D.-3.2) to 2.23 (S.D.-1.69) i.e. 71.13% one month after surgeries. The mean SNOT score improvement was from 6.57 (S.D.-2.36) to 5.88 (S.D.-2.6) i.e. 10.48% after one month in the control groups. There was a statistically significant improvement (p< 0.001) in post operative SNOT-10 score in patients who underwent septoplasty. However, improvement in control group was not found to be statistically significant (p> 0.05) using the same score. Comparison of post-operative SNOT scores between cases and controls was statistically significant. Comparison of difference of SNOT score pre and post operatively between cases and controls using Z test for mean (P<0.001) was also statistically significant.
