For nearly a century the gold standard treatment for epiphora and nasolacrimal duct obstruction has been dacryocystorhinostomy (DCR). The definitive treatment of severe canalicular stricture remains conjunctivodacryocystorhinostomy. Although the high success rate of open external approaches continues to be confirmed in the literature, there have been promising advances for endocanalicular surgery and endonasal DCR. Despite a significant narrowing of the gap in outcomes, external DCR may hold the advantage in its ease of performance and lower economic impact. A minor controversy exists over the role of routine postoperative antibiotics. Intraoperative intravenous antibiotic dosing may be as effective as postoperative systemic antibiotics for patients at high risk of infection.
近一个世纪以来，泪囊鼻腔吻合术（DCR）一直是治疗泪溢和鼻泪管阻塞的金标准治疗方法。严重泪小管狭窄的最终治疗方法仍然是结膜泪囊鼻腔吻合术。尽管开放式外部手术的高成功率在文献中不断得到证实，但泪小管内手术和鼻内镜下泪囊鼻腔吻合术也取得了令人鼓舞的进展。尽管手术效果的差距显著缩小，但外部泪囊鼻腔吻合术在操作简便性和较低的经济影响方面可能具有优势。对于常规术后使用抗生素的作用存在轻微争议。对于感染风险高的患者，术中静脉注射抗生素可能与术后全身使用抗生素一样有效。
