PURPOSE
External dacryocystorhinostomy (DCR) surgeries are cost-effective with excellent success rates. The present study was designed to compare the safety and efficacy of conventional external DCR versus external DCR using Pawar silicone implant in chronic dacryocystitis.
METHODS
This is a prospective, comparative, interventional case series over a period of 18 months with patients managed by external DCR surgery with and without Pawar implant. Institutional review board approval was obtained before the study. The success of the surgery was objectively measured by sac patency on syringing at the last follow up.
RESULTS
A total of 65 patients with chronic dacryocystitis were included in the study. The mean age of patients in the series was 41.43 years (median, 41 years; range, 12 years-60 years). All patients presented with epiphora (100%) and underwent external DCR and were chosen for conventional surgery (n = 33, 51%, group 1) or Pawar silicone implant surgery (n = 32, 49%, group 2) on a random basis. The mean duration of the surgery from the time of skin incision to skin closure for group 1 was 27.7 minutes (median, 26 minutes; range, 21-30 minutes) while in group 2, it was 75.5 minutes (median, 75 minutes; range, 60-88 minutes), which was statistically significant (P < 0.01). The success rate of the procedure done in group 1 was 90% which increased to 97% after the management of failed cases as compared to the success rate in group 2 of 91% and 94%, before and after the management of failed cases, respectively.
CONCLUSION
External DCR using Pawar implant is a safe surgery which is faster than conventional external DCR with almost equal success rates between both the procedures.
目的
外路泪囊鼻腔吻合术（DCR）具有成本效益，成功率高。本研究旨在比较慢性泪囊炎患者行传统外路 DCR 与 Pawar 硅胶植入物外路 DCR 的安全性和有效性。
方法
这是一项前瞻性、对照、干预性病例系列研究，研究时间为 18 个月，对接受外路 DCR 手术且不使用 Pawar 植入物的患者和接受外路 DCR 手术联合 Pawar 植入物的患者进行比较。研究前获得机构审查委员会批准。通过最后一次随访时的冲洗确定手术的成功率。
结果
共有 65 例慢性泪囊炎患者纳入本研究。该系列患者的平均年龄为 41.43 岁（中位数为 41 岁；范围为 12 岁至 60 岁）。所有患者均有溢泪（100%），并接受外路 DCR 治疗，其中 33 例（51%，第 1 组）患者接受传统手术，32 例（49%，第 2 组）患者随机接受 Pawar 硅胶植入物手术。第 1 组从皮肤切口到皮肤缝合的手术平均持续时间为 27.7 分钟（中位数为 26 分钟；范围为 21-30 分钟），而第 2 组为 75.5 分钟（中位数为 75 分钟；范围为 60-88 分钟），差异有统计学意义（P<0.01）。第 1 组的手术成功率为 90%，在处理失败病例后增加到 97%，而第 2 组的成功率为 91%和 94%，在处理失败病例之前和之后。
结论
Pawar 硅胶植入物外路 DCR 是一种安全的手术，比传统外路 DCR 更快，两种手术的成功率几乎相同。
