The objective is to compare the success rates of revision endonasal dacryocystorhinostomy (END-DCR) with revision external dacryocystorhinostomy (EXT-DCR). The present retrospective study was conducted between January 2002 and July 2009. Seventy-four consecutive patients (17 males, 57 females) who had epiphora or recurrent dacryocystitis after a previous failed EXT-DCR procedure were enrolled in the study. The END-DCR group consisted of 43 patients (10 males, 33 females) who underwent 44 END-DCRs, whereas the EXT-DCR group included 31 patients (7 males, 24 females) who underwent 31 dacryocystorhinostomies (DCRs). Successful DCR was defined as relief of symptoms as demonstrated by saline irrigation at the last post-operative visit. Further nasal surgery was performed in 18 (40.9%) eyes in the END-DCR group. The average follow-up time for the END-DCR and EXT-DCR groups was 11 and 9 months, respectively. The success rate was 77.4% (24/31 DCRs) in the END-DCR group, and 84.1% (37/44 DCRs) in the EXT-DCR group. There was no significant difference between the groups regarding overall success (p = 0.465). END-DCR is as safe and efficient technique as external approach with low complication rates in revision cases. END-DCR yields good esthetic and functional results and has a success rate similar to that of the external approach.
目的是比较经鼻内镜下鼻腔泪囊吻合术（END-DCR）与经外路鼻腔泪囊吻合术（EXT-DCR）的成功率。本回顾性研究于 2002 年 1 月至 2009 年 7 月进行。74 例连续患者（男性 17 例，女性 57 例）在先前失败的 EXT-DCR 手术后出现溢泪或复发性泪囊炎。END-DCR 组 43 例（男性 10 例，女性 33 例）行 44 例 END-DCR，EXT-DCR 组 31 例（男性 7 例，女性 24 例）行 31 例 DCR。成功的 DCR 定义为末次术后冲洗时症状缓解。在 END-DCR 组中，有 18 只眼（40.9%）需要进一步行鼻内手术。END-DCR 和 EXT-DCR 组的平均随访时间分别为 11 个月和 9 个月。END-DCR 组的成功率为 77.4%（24/31 DCR），EXT-DCR 组为 84.1%（37/44 DCR）。两组在总体成功率方面无显著差异（p=0.465）。在复发性病例中，与外路方法相比，END-DCR 是一种安全有效的技术，并发症发生率低。END-DCR 可获得良好的美学和功能效果，成功率与外路方法相似。
