目的:观察新型泪道引流装置治疗泪道阻塞及泪小管断裂的临床疗效。方法:选择慢性泪囊炎、鼻泪管阻塞者106例行鼻泪道逆植球头硅胶管术,术后定期冲洗泪道并点抗生素眼液,3～6mo拔管;泪小管阻塞及外伤性泪小管断裂者88例行鼻泪道环形硅胶管植入术,术后滴抗生素眼液,6～12mo拔管。结果:拔管后5例鼻泪管阻塞,4例慢性泪囊炎,3例泪小管阻塞者复发溢泪,其他患者均无复发,泪道冲洗通畅。结论:新型泪道引流装置治疗泪道阻塞及泪小管断裂效果好、方法简单、组织创伤小、无局部及全身副作用,具有临床推广应用价值。

AIM:To observe the results of neotype tractus lacrimalis drainage system for the treatment of lacrimal duct obstruction and canaliculus breakage.METHODS:One hundred and six cases with chronic dacryocystitis or nasolacrimal duct obstruction were performed the inverse ball silicone tube implantation in nasolacrimal canal.Lacrimal passages were douched regularly after operation and 3-6 months tube was extubated;88 cases with lacrimal duct obstruction and traumatic canaliculus breakage were implanted ring silicone tube in nasolacrimal duct,and 6-12 months tube was extubated.RESULTS:Five cases with nasolacrimal duct obstruction,4 cases with chronic dacryocystitis,3 cases with lacrimal duct obstruction recurred epiphora,the other cases have no recurrent.Lacrimal passages flush was unobstructed after surgery.CONCLUSION:Neotype tractus lacrimalis drainage system for the treatment of lacrimal duct obstruction and canaliculus breakage is an effective,simple process,and have the advantages including mini-traumato-architecture,no part or system adverse reaction,worthy clinical genera-lization and application.
