A Randomized Multi-Center Single Blind Active-Controlled Matched Pairs Clinical Study to Evaluate Prevention of Adhesion Formation and Safety of HyFence in Patients After Endoscopic Sinus Surgery

摘要

ObjectivesRecurrent mucosal disease and anatomic obstruction are commonly cited causes of failed endoscopic sinus surgery (ESS). Hyaluronic acid (HA) has been reported to reduce scarring and to promote wound healing in sinonasal surgery. HyFence is HA stabilized by 1, 4-butandiol diglycidyl ether, which makes it less-water-soluble and highly viscoelastic. The purpose of this study is to examine the anti-adhesion effect of HyFence after ESS compared to that of HA-CMC (Guardix-Sol).
