Using the sino-nasal outcome test (SNOT-22) to study outcome of treatment of nasal obstruction.

OBJECTIVE

To validate the sino-nasal outcome test (SNOT-22) as an outcome measure for nasal obstruction, and to determine if it correlates with the nasal obstruction and septoplasty effectiveness (NOSE) scale.

STUDY

DESIGN

Prospective cohort study.

METHODS

All patients presenting to our otolaryngology clinic for nasal obstruction secondary to nasal septal deviation and/or inferior turbinate hypertrophy between August 2020 and June 2022 were asked to fill both the SNOT-22 and the NOSE questionnaires. Demographics and comorbidities were reviewed. Patients with chronic rhinosinusitis (CRS) were excluded. SNOT-22 total and subdomain scores were then compared to NOSE scores.

RESULTS

126 patients completed both surveys. Average age was 42.6 years (range 13.8-78.3 years), and 40.5 % were female. 35 patients had septoplasty and inferior turbinoplasty (IT), 34 had functional septorhinoplasty and IT, 6 patients had IT, 7 had nasal septal perforation repair and 44 patients had medical treatment. Overall, SNOT-22 and NOSE scores correlated well preoperatively and postoperatively (r = 0.54, p < 0.0001; r = 0.68, p < 0.0001 respectively). The rhinologic and sleep SNOT-22 subdomains scores had the strongest correlation to NOSE score (r = 0.56, p < 0.0001; r = 0.64, p < 0.0001 respectively). Both NOSE and SNOT-22 scores showed improvement postoperatively [NOSE: 67.4 vs 25.1 (p < 0.0001) at 3 months, 69.5 vs 34 (p < 0.0001) at 6 months; SNOT-22: 37.1 vs 25.2 (p = 0.002) at 3 months, 38.1 vs 22.6 (p = 0.002) at 6 months]. No significant improvement in NOSE or SNOT scores was seen in the medical treatment group.

CONCLUSION

SNOT-22 instrument can be used to study the outcome of treatment for nasal obstruction secondary to nasal septal deviation and/or inferior turbinate hypertrophy.
