方法：回顾性临床研究。选取2017-09/2020-06在我院就诊的泪道疾病患者28例28眼作为研究对象，均行结膜囊泪囊鼻腔吻合术。术后随访6～12mo，观察患者手术效果、满意度及术后并发症情况。

结果：本组患者术后荧光素钠染料排泄试验阳性率为96%(27/28)，手术成功率为96%(27/28)，其中治愈率为68%(19/28)，好转率为28%(8/28)，无效率为4%(1/28)，患者总体满意度为93%(26/28)。术后并发症包括眼部异物感(28眼)、球结膜充血(11眼)、鼻腔结膜囊渗血(8眼)及泪道引流管脱出(1眼)。

结论：四瓣技术用于改良结膜囊泪囊鼻腔吻合术手术成功率高，并发症少，安全有效。

METHODS: Retrospective clinical study. A total of 28 patients(28 eyes)who were treated in our hospital from September 2017 to June 2020 with lacrimal disease were selected as the research subjects. These patients were treated with conjunctivo-dacryocystorhinostomy. Postoperative follow-up was performed for 6-12mo to observe the surgical effect, satisfaction and postoperative complications.

RESULTS: The positive rate of fluorescein sodium dye excretion test after surgery in this group of patients was 96%(27/28), the success rate of surgery was 96%(27/28), the cure rate was 68%(19/28), the improvement rate was 28%(8/28), the ineffective rate was 4%(1/28)and the overall satisfaction of patients was 93%(26/28). The postoperative complications included ocular foreign body sensation(28 eyes), conjunctival hyperemia(11 eyes), nasal cavity and conjunctival sac bleeding(8 eyes)and lacrimal passage tube out(1 eye).

CONCLUSION: The four-valve technique is used to improve the conjunctivo-dacryocystorhinostomy with high success rate, less complications, safety and effectiveness.
