硅胶管环形植入治疗泪小管断裂的临床应用

The Clinical Application of Annular Silicone Tube Insertion in the Treatment of Canaliculi Laceration

目的：探讨硅胶管环形植入在泪小管断裂吻合术中的应用,并评价其临床价值。方法：对33例（33眼）外伤性泪小管断裂患者,在手术显微镜下寻找鼻侧断端,利用自制探针引导硅胶管呈环形骑跨于上下泪小管,吻合泪小管周围组织2~3针,使泪道恢复正常解剖结构。硅胶管留置3~6个月。结果：拔管后随访6~12个月。33例患者全部成功置管吻合,其中治愈32例（96.97%）,好转1例（3.03%）。结论：硅胶管环形植入治疗泪小管断裂,安全有效,成本低,成功率高,可为其他泪道置管术提供有益的借鉴与参考。

Objective： To investigate the application of annular silicone tube insertion on the repair of canaliculi laceration, and estimate its clinical effect.Method： 33 patients（33 eyes） of traumatic canaliculus laceration were selected, the nasal side of disrupted canalieuli lacrimalis under surgery microscope was located and the silicone tube annular overriding on the canaliculi lacrimalis by self-made probe was used, and surrounding tissues of the lacrimal canaliculus for 2-3 needles was anastomosed, the lacrimal passage was reformed its normal anatomic structure.All the silicone tubes were indwelled for 3-6 months,Result： All the patients were followed up 6-12 months after the tubes were pulled out.The 33 cases（33 eyes） of canalictdar laceration patients were all successfully anastomosed by silicone tube insertion.Of which, 32 cases were cured（96.97%）, and 1 case was improved（3.03%）. Conclusion： It is an safe and effective method of lacrimal canaliculus anastomosis operation, with low cost and high rate of success, and will provide helpful reference to other lacrimal passage intubation.
