Efficacy of hyaluronic acid in the treatment of nasal inflammatory diseases: a systematic review and meta-analysis
Abstract
Background: Hyaluronic acid (HA), the main component of the extracellular matrix, has the ability to promote tissue repair and regulate inflammation. It is used in otolaryngology as an adjuvant treatment to alleviate postoperative nasal symptoms. However, there is currently insufficient evidence demonstrating the therapeutic efficacy of HA for patients with nasal inflammatory diseases (NIDs). Therefore, this study aimed to evaluate the efficacy and safety of topical HA in the treatment of NID patients without receiving surgery. Methods: In this meta-analysis, comprehensive searches were conducted in PubMed, Embase, the Cochrane Central Register of Controlled Trials, and Web of Science. Keywords searched included "hyaluronic acid," "sinusitis," "allergic rhinitis," "rhinitis," and "randomized controlled trials (RCTs)." The Cochrane Collaboration's "Risk of Bias Assessment" tool was used to assess the quality of the included trials, and the meta-analysis was performed using the RevMan 5.3 and STATA 15 statistical software. Results: A total of 11 articles and 825 participants were enrolled. For the primary outcomes, the pooled results revealed that HA significantly improves nasal obstruction (SMD, -0.53; 95% CI, -0.92 to -0.14; p = 0.008; and I2 = 79%) and rhinorrhea (SMD, -0.71; 95% CI, -1.27 to -0.15; p = 0.01; and I2 = 90%) in patients with NIDs. As for the secondary outcomes, the pooled results demonstrated that when compared with the control group, HA could significantly…
