To evaluate the efficacy of a sleeve technique during endoscopic dacryocystorhinostomy (DCR) in primary nasolacrimal duct obstruction (NLDO) patients with a high lacrimal sac.
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.
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).
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.
评估在原发性鼻泪管阻塞（NLDO）且泪囊高位患者的内镜下泪囊鼻腔造口术（DCR）中采用套管技术的疗效。
回顾性分析45例（49眼）因原发性NLDO且泪囊高位而行内镜下DCR患者的病历资料。19例（21眼）患者采用钻头去除覆盖泪小管共同开口的厚上颌骨，并插入双泪小管硅胶管（第1组）。26例（28眼）患者未去除厚上颌骨，而是在双泪小管硅胶管中插入套管（第2组）。术后6个月评估成功率，并测量鼻内黏膜造口大小。
第1组和第2组的成功率分别为90.5%和96.4%（P = 0.400）。第1组和第2组的鼻内黏膜造口大小分别为1.7±0.7mm和3.1±1.0mm，差异有统计学意义（P = 0.042）。
在原发性NLDO且泪囊高位患者中，DCR联合插入硅胶管和套管在不使用钻头的情况下成功率令人满意。与传统手术方法相比，有助于扩大鼻内黏膜造口的大小。
