Brief summary

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.

Interventions

DRUGIsotonic saline

Nasal isotonic saline irrigation (240 mL, 0.9% NaCl) administered through nasal rinse bottle.

DRUGHypertonic Nasal Wash

Nasal hypertonic saline irrigation (240 mL, 1.8% NaCl) administered through nasal rinse bottle.

DRUGFluticasone Propionate

Fluticasone nasal spray administered two sprays to each nare twice a day

Design outcomes

Primary

MeasureTime frameDescription
Mean change in SNOT-22 scoreBeginning of week 2 and end of week 3 of the respective treatment periodParticipants will complete the Sinonasal Outcome Test (SNOT)-22, a validated questionnaire for assessing symptoms of chronic rhinosinusitis, before and after completing each intervention. SNOT-22 is a validated scale which measures sinonasal symptoms for sinusitis patients. The 22 questions are rated on a scale of 0-5 for a maximum total score of 110. Higher scores represent more symptomatic patients.
Mean change in NOSE scoreBeginning of week 2 and end of week 3 of the respective treatment periodParticipants will complete the Nasal Obstruction Symptom Evaluation (NOSE), a validated questionnaire for assessing symptoms of nasal obstruction, before and after completing each intervention. NOSE scores can range from 5 to 100, with higher scores indicating worse symptoms. Classes are mild (5-25), moderate (30-50), severe (55-75), and severe (80-100).

Secondary

MeasureTime frameDescription
Participant-reported compliance with sinus rinsesFrom the beginning of week 2 to the end of week 3 of the respective treatment periodParticipants will self-report the number of days in the two week rinsing period in which they used rinses.

Other

MeasureTime frameDescription
Frequency (by severity) of adverse effects after sinus rinsesFrom the beginning of week 2 to the end of week 3 of the respective treatment periodThe frequency (by severity) of the following patient-reported adverse effects: * Nasal burning/pain * Headaches * Ear pain * Sneezing * Nose bleeds
