Abstract

BACKGROUND AND OBJECTIVES
The most frequent complication of FESS (functional endoscopic sinus surgery) is stenosis of the operation site. The complication may influence the postoperative wound healing and the outcome of surgery. There are several measures proposed to prevent the complication. We sought to determine the efficacy of GUARDIX-SL which is made from sodium hyaluronate and sodium carboxymethylcellulose in soluble form. MATERIALS AND METHOD: For 7 rabbits, we made a surgical opening anterior to sinus ostium of the maxillary sinuses on both sides. We put the gelfoams soaked with GUARDIX-SL into the left openings and those soaked with normal saline into the right openings as a control group. We measured the size of the openings after two weeks. RESULTS: There was no synechiae in GUARDIX-SL group whereas we found synechiae developed in two openings in the control group. The mean area of the opening was 9.29 mm2 and 1.61 mm2 in GUARDIX-SL group and the control group (p=0.027), respectively. CONCLUSION: GUARDIX-SL was effective in reducing postoperative stenosis in the animal model.
