To discuss the removal time of a nasolacrimal silicone tube stent by reporting three cases with canalicular laceration due to prolonged indwelling of the stent. This study involved three cases of nasolacrimal duct obstruction treated by endoscopic dacryocystorhinostomy with silicone tube insertion. The mean indwelling time of the silicone tube was 9.3 months and all of the patients had lower canalicular laceration near the common canaliculus. One patient presented with a complaint of canthal pain, blurred vision, and epiphora while the other two patients reported no complaint. The nasal endoscopic examination revealed a narrow fibrotic ostium below the medial concha. The silicone tubes were removed. To increase the success rate of the operation, the removal time for nasolacrimal silicone tubes after dacryocystorhinostomy is also important. Our findings indicate that physicians should be aware of the potential problems related to prolonged intubation.
通过报告3例因鼻泪管硅胶管留置时间过长导致泪小管撕裂的病例，探讨鼻泪管硅胶管支架的取出时间。本研究纳入3例经鼻内镜下泪囊鼻腔吻合术联合硅胶管植入治疗的鼻泪管阻塞患者。硅胶管的平均留置时间为9.3个月，所有患者在泪总管附近均有下泪小管撕裂。1例患者出现内眦部疼痛、视力模糊和溢泪症状，另外2例患者无不适主诉。鼻内镜检查发现中鼻甲下方有狭窄的纤维化开口。取出硅胶管。为提高手术成功率，泪囊鼻腔吻合术后鼻泪管硅胶管的取出时间也很重要。我们的研究结果表明，医生应意识到与长期插管相关的潜在问题。
