A retrospective review of 242 consecutive dacryocystorhinostomies (DCRs) revealed no association between failure and either age, gender, or etiology of the nasolacrimal obstruction. However, silicone intubation of the nasolacrimal system was associated with a statistically significant increase in the failure rate of primary DCR. We postulate that silicone tubing by inciting granuloma formation in the nose and lacrimal fossa, predisposes to DCR failure. Routine use of silicone tubing in DCR should be avoided unless there is canalicular scarring, a large valve of Rosenmueller occluding the common canaliculus, or a small contracted or scarred lacrimal sac.
对242例连续性泪囊鼻腔吻合术（DCR）进行回顾性研究发现，手术失败与年龄、性别或鼻泪管阻塞的病因均无关联。然而，鼻泪管系统硅胶插管与原发性DCR失败率的统计学显著增加相关。我们推测，硅胶管通过在鼻腔和泪囊窝引发肉芽肿形成，易导致DCR失败。除非存在泪小管瘢痕、阻塞共同泪小管的大 Rosenmueller 瓣，或小的收缩或瘢痕化泪囊，否则应避免在DCR中常规使用硅胶管。
