Materials and Methods: The medical records of 45 patients (49 cases) undergoing endoscopic DCR for primary NLDO with a high lacrimal sac were retrospectively reviewed. In 19 patients (21 cases), the thick maxilla covering the common canalicular opening was removed using a drill and a bicanalicular silicone tube was inserted (group 1). In 26 patients (28 cases), instead of removal of the thick maxilla, a sleeve was inserted into the bicanalicular silicone tube (group 2). At 6 months postoperatively, the success rate was evaluated and the size of the intranasal mucosal ostium was measured. Results: The success rates in group 1 and 2 was 90.5% and 96.4%, respectively (P = 0.400). The intranasal mucosal ostium in group 1 and 2 measured 1.7 ± 0.7 mm and 3.1 ± 1.0 mm, respectively, and the difference was significant (P = 0.042). Conclusions: In primary NLDO patients with a high lacrimal sac, DCR inserting a silicone tube and a sleeve together had a satisfactory success rate without using a drill. In comparison with traditional surgical methods, it helped enlarge the size of the intranasal mucosal ostium.}, URL ={https://journals.lww.com/ijo/pages/default.aspx/article.asp?issn=0301-4738;year=2014;volume=62;issue=4;spage=442;epage=445;aulast=Kim;t=6}, eprint ={https://journals.lww.com/ijo/pages/default.aspx/article.asp?issn=0301-4738;year=2014;volume=62;issue=4;spage=442;epage=445;aulast=Kim;t=6} }
