Nasal solutions are part of the recommended therapy of chronic rhinosinusitis (CRS). Formulations containing hyaluronic acid (HA) may represent a promising topical treatment in CRS patients in light of the anti-inflammatory and protective effect of HA on the sinonasal mucosa.

Abstract
BackgroundNasal solutions are part of the recommended therapy of chronic rhinosinusitis (CRS). Formulations containing hyaluronic acid (HA) may represent a promising topical treatment in CRS patients in light of the anti-inflammatory and protective effect of HA on the sinonasal mucosa.ObjectivePrimary aim was to evaluate the performance of a new nebulized HA nasal hypertonic solution in the relief of symptoms of CRS. Secondarily, evaluation of symptoms improvement, endoscopic nasal findings, and safety profile were assessed.MethodsA monocenter, single arm, not controlled, premarket clinical trial on a new nasal solution containing HA was performed. All the included patients had a history of previously diagnosed or recurrent CRS or they had received a clinical diagnosis of CRS defined, according to the European Position Paper on Rhinosinusitis and Nasal Polyps 2012. Each patient was evaluated on 3 visits. Endoscopic nasal examination and Nasal Obstruction Symptom Evaluation Instrument questionnaire filling were performed during each visit. Patients' adherence to treatment and overall satisfaction, patients' and investigator's global evaluation of performance, and safety parameters were also assessed.ResultsEighty patients were enrolled. The use of the investigated HA nasal solution revealed to be significantly effective in the relief of symptoms of CRS.
