Objective/Hypothesis
The Nasal Obstruction Symptom Evaluation (NOSE) is a disease specific quality of life instrument developed and validated in adults. The objective of this study is to evaluate the validity of the NOSE scale for pediatric nasal obstruction. We also examined the effect of septoplasty with bilateral inferior turbinate reduction in this population.
Study Design
A validation study at a tertiary care children's hospital.
Methods
Thirty‐eight pediatric patients who underwent septoplasty and bilateral inferior turbinate reduction between 2014 and 2018 were included. Patients were administered the NOSE instrument on the day of their clinic evaluation, the day of surgery, and at their 6 to 8‐week post‐operative appointment. A sample of 40 pediatric patients with non‐rhinologic complaints was also included. Confirmatory factor analysis was performed to evaluate the factorial validity of the NOSE instrument.
Results
Of the 78 patients included, the mean age was 15.4 years (SD 3.4). In the confirmatory factor analysis, factor loadings were all significant and ranged from 0.95 to 0.99. Internal consistency reliability using Omega and maximal reliability H indices were well above recommended standards (Omega = 0.983 and maximal H = 0.988). Test–retest reliability was also adequate. Mean NOSE scores significantly improved following surgery (from 96.7 [SD 6.2] to 8.8 [SD 7.8]; mean difference = −87.9; 95% CI: −84.5, −91.3; P < .001). Similar improvements were observed across age groups.
Conclusions
The NOSE scale is a valid and reliable quality of life instrument for pediatric patients with nasal obstruction. Nasal septoplasty with bilateral turbinate reduction substantially improved symptoms of nasal obstruction.
