Mean Intra-patient Change in SNOT-20 Score at 24 Weeks Post-procedure Compared to Baseline 24 weeks [clinicaltrials_resource:1ae34b4e92d6e2deef7ae00bdfe4f7e1]

The 20 question Sino-Nasal Outcome Test (SNOT-20) will be used to evaluate sinus symptoms and sinus-symptom related quality of life (QOL) at baseline, 1 week, 4 weeks, 24 weeks and 52 weeks post-procedure. The change in SNOT-20 score at each post-procedure time point will be evaluated compared to baseline SNOT-20 score. Each of the 20 questions in the SNOT-20 survey is scored on a scale of 0 to 5, where '0' represents 'no problem' and '5' represents 'problem as bad as it can be'. The 20 questions are expressed as a mean of the scores. Therefore, the minimum mean score is zero and the maximum mean score is 5.
