SILICON STENT AS A FAILURE IN ENDONASAL ENDOSCOPIC DCR

Objective:1. To evaluate the effectiveness of using the silicon stent in endonasalendoscopic DCR 2.To compare the results of endonasal endoscopic DCR using silicon stent with endonasal endoscopic DCR without silicon stent.Material and methods: our study included 36 patients were divided into two groups. First group underwent endonasal endoscopic DCR using silicon stent and in the second group endonasal endoscopic DCR was done without using silicon stent.Postoperative follow up was carried out at the end of first,third,six,and 1oth week and the role of silicon stent was compared Results: we found that with the use of silicon stent results were not improving despite the risk of failure of the surgery was increased with stent due to the formation of granulation tissue in the lacrimal sac region.
