Objectives: To validate each of the sino-nasal outcome test (SNOT-22) and the sinus and nasal quality of life (SN5) surveys for the adolescent population defined as 12 to 18 years old, and to determine if they correlate in regard to reports of sinonasal symptoms and quality of life.
Study design: Cross-sectional study.
Methods: Adolescent patients, age 12 to 18 years old, presenting to our otolaryngology clinic between August 2020 and June 2021 were asked to fill both the SNOT-22 and the SN5 forms. Demographics and comorbidities were reviewed. Patients recruited were then divided into a sinonasal cohort (those with chronic sinonasal symptoms) and a control cohort (those who did not have any sinonasal disorders at time of visit).
Results: One hundred fifteen patients completed both surveys, 80 patients in the sinonasal cohort and 35 patients in the control cohort. Average age was 14.9 years, and 49.6% were female. Mean SNOT-22 and SN5 scores were significantly higher in the sinonasal cohort as compared with the control cohort which confirmed validity of both surveys for the adolescents. Good test-retest reliability for both surveys was obtained (r = 0.76 for SNOT-22, and r = 0.64 for SN5). SNOT-22 and SN5 scores correlated well in both the sinonasal cohort (r = 0.63, p < 0.0001) and the control cohort (r = 0.61, p = 0.0003). Both surveys strongly predicted chronic sinonasal disorders with an odds ratio of 2.5 for SNOT-22 and 2.2 for SN5.
Conclusion: Both instruments can be used to study the outcome of treatment for sinonasal disorders in adolescent patients.
