This research study will be completed by enrolling a prospective, observational cohort study to evaluate medical versus surgical treatment outcomes for chronic sinus disease. This investigation will compare quality of life outcomes between each treatment type, as well as measure cellular and molecular markers of inflammation in the sinus mucosa, to create models that predict improvement in quality of life following treatment.
