Antiadhesive Effect of the Mixed Solution of Sodium Hyaluronate and Sodium Carboxymethylcellulose after Endoscopic Sinus Surgery

Background We evaluated the clinical efficacy and safety of the mixed solution of sodium hyaluronate and sodium carboxymethylcellulose (HA-CMC) for prevention of adhesion after endoscopic sinus surgery. Methods Preoperative computed tomography (CT) scans were graded. At the completion of surgery, HA-CMC was applied to Merocel and repeatedly applied after the removal of Merocel. As a control, normal saline was applied. Endoscopic examination was performed postoperatively and grading was done. Results The rate of adhesion was the highest at 2 weeks postoperatively and was significantly lower in the HA-CMC–treated group than the control on all postoperative days. The grouping of cases by CT scores at 2 weeks postoperatively showed lower adhesion formation with the HA-CMC treatment than the control. The safety profile of the patients was normal at 4 weeks postoperatively. Conclusion HA-CMC is an efficacious and safe material in decreasing the incidence of adhesion after endoscopic sinus surgery.
