Abstract

Background: This study was designed to prospectively evaluate the role of nebulized hyaluronic acid (HA) given for 10 days/mo over 3 months as adjunct treatment to minimize symptoms and preventing exacerbation of chronic rhinosinusitis (CRS). Methods: Thirty-nine eligible patients were randomized to receive nebulized 9-mg sodium hyaluronate nasal washes plus saline solution (21 patients) or 5 mL of saline alone (18 patients), according to an open-label, parallel-group design, with blind observer assessment. A questionnaire about main CRS discomfort and nasal endoscopy for mucous discharge and/or mucosal edema of nasal cavities was used to assess primary outcomes of treatments. Secondary outcome measures included side effects and satisfaction. Results: HA significantly improved quality of life in CRS patients according to the CRS questionnaire (16± 3.72 versus 11.52 ± 4.28; p < 0.001), contrary to saline group scores (18.92 ± 3.09 versus 18.21 ± 3.21; p = 0.55). The HA group showed significantly reduced osteomeatal edema (2.42 versus 1.52; p < 0.001) and secretions (0.95 versus 0.42; p < 0.001), whereas there was no statistically significant difference in the saline group he compliance to the treatment was similar in both groups and no side effects were recorded. Conclusion: The results of this study suggested that intermittent treatment with topical 9-mg sodium hyaluronate plays a role in minimizing symptoms and could prevent exacerbations of CRS.
