Antiadhesive effect of the mixed solution of sodium hyaluronate and sodium carboxymethylcellulose after endoscopic sinus surgery

Abstract

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.
