Abstract
Purpose: To evaluate the efficacy of a sleeve technique during endoscopic dacryocystorhinostomy (DCR)

sac. 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.
