少年儿童泪小管断裂的手术

目的分析少年儿童泪小管断裂吻合术的特点,探讨采用缝合固定于鼻前庭的人工泪管植入的效果。方法全麻或局部麻醉联合基础麻醉支持下,对16例（16眼）少年儿童（3～15岁）泪小管断裂者行泪小管吻合,术中采用硬膜外麻醉导管将带线硅胶人工泪管引导入泪道作为泪道支撑物,人工泪管两端分别通过上、下泪点植人鼻泪道并固定于鼻前庭。结果术后随诊观察3个月～3年。15例术后泪道冲洗通畅,1例出现轻度溢泪,泪道冲洗不通,成功率93—7％。16例人工泪管均在位,均在预期时间拔管。结论少年儿童泪小管断裂吻合术,采用带线硅胶制人工泪管作为泪道支撑物,固定于鼻前庭,能较好保持少年儿童人工泪管位置,手术成功率高。

Surgical repair of the laceration of the lacrimal canalicalus in teenager and children

Objective To study the effect and characteristics of lacrimal canaliculus anastomosis with artificial lacrimal canalieulus under general anesthesia to teenager and children. Methods 16 teenager and children (aged from3 ～ 15 years old) who consecutively underwen tlacrimal canaliculus anastomosis in general anesthesia. During the surgeriy, artificial tears tube was used in lacrimal canalieulus. The artificial tears tube was sutured in nasal vestibule during the operation. Results After 3 months to 3 years follow-up period, 15 cases were unobstructed, without epiphora,while 1 case was obstructed of lacrimal passagers with some epiphora. The final cured rate was 93.7％ (15/16) The artificial tears tube of most cases kept stable within 2 months post-operatively. Conclusion The effect of lacrimal canaliculus anastomosis with artificial tears tube under general anesthesia to children and adolescents is well. The silicone tube can be stable within 2 months post-operatively.
