The purpose of this study is to compare intranasal fluticasone spray with budesonide nasal
saline rinses in both the upright and head forward positions in patients who have had
functional endoscopic sinus surgery (FESS) for chronic rhinosinusitis with nasal polyposis
(CRSwNP) and measure differences in Sinonasal Outcome Test-22 (SNOT-22) scores and Lund-
Kennedy scores on rigid nasal endoscopy at time points 1 week, 3 weeks, 6 weeks, 2 months, 4
months, and 6 months post-op.
