Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The study aims to determine the safety and efficacy of buffered hypertonic (1.8%) saline nasal rinses as compared to isotonic saline nasal rinses in patients with chronic rhinosinusitis (CRS). Evidence from basic science research suggests that hypertonic solutions may have beneficial effects over isotonic saline rinses; however prior clinical studies on this topic have been inconclusive and limited due to highly variable inclusion criteria, large variability in the volume and concentration of irrigation solution, and inconsistent outcome measures. The goal of the study is to utilize a cross over study design to directly compare the impact of two different types of saline irrigation. Primary aim: Compare the efficacy of buffered hypertonic saline irrigations to buffered isotonic saline irrigations on patient reported outcome measures of chronic rhinosinusitis symptoms and nasal obstruction in patients with CRS. Based on in vivo data and prior clinical studies, the investigators expect participants will experience greater symptom improvement with hypertonic saline rinses as compared to isotonic saline irrigations. Hypothesis: Participants will have greater improvement in patient reported outcome measures (SNOT-22 and NOSE) when using buffered hypertonic sinus irrigations as compared to buffered isotonic saline irrigations.
