Prospective study on the functional outcome of septoplasty

Background: A thorough assessment of nasal obstruction remains a matter of debate with no accepted subjective and objective measurement tools. The purpose of this study was to use a cost-effective tool for objective assessment of nasal obstruction and compare it with subjective scores.Methods: This was a longitudinal, prospective study conducted at a tertiary care center on patients undergoing septoplasty for deviated nasal septum (DNS) from March 2016 to August 2017. All patients were assessed pre- and post-operatively at 3 months with nasal peak inspiratory flow, sino-nasal outcome test (SNOT-22) and nasal obstruction symptom evaluation (NOSE) questionnaire to determine post-operative improvement and correlation between objective and subjective scores.  Results: 64 patients were included in the study with 16 females and 48 males. Male patients had higher peak nasal inspiratory flow (PNIF) score post-operatively. Younger patients (less than 25 years) showed significant subjective improvement compared to older patients post-operatively using NOSE questionnaire. Significant improvement in PNIF, SNOT-22 and NOSE scores post-operatively using paired student-t test. There was moderate correlation between PNIF values and subjective scores before surgery and excellent correlation between the subjective SNOT-22 and NOSE scores before and after surgery.Conclusions: PNIF is a cheap, portable, and convenient method for assessing nasal patency. Subjective and objective scores have good correlation, with improvement in all scores post-surgery. Men may show more objective improvement and early intervention at younger age may provide more subjective improvement.
