The self-crosslinked hyaluronic acid (scHA) and steroids are considered as efficient factors for postoperative management after chronic rhinosinusitis (CRS) nasal surgery. This randomized clinical trial is designed to investigate the efficacy and potential of scHA gel as a topical drug sustained release carrier for steroid of budesonide. The study is performed with 30 patients of chronic rhinosinusitis with nasal polyps (CRSwNP) who underwent functional endoscopic sinus surgery (FESS). The single application of scHA was assessed in the control patient group for postoperative recovery. In the treatment patient group, the combination of scHA/budesonide was applied for postoperative management. The patients are followed up in 2 weeks, 4 weeks and 12 weeks after surgery. The combination of scHA/budesonide results in better endoscopic scoring and mucus evaluation than the single scHA application. The results indicate that the combination of scHA/budesonide is a valuable treatment for the FESS postoperative management and implies the potential of scHA gel as a topical drug sustained release scaffold.
