下泪小管断裂直接插管一期显微吻合术

目的: 观察显微镜下进行泪小管断端直接插管显微吻合的疗效。方法: 23例下泪小管断裂患者,在显微镜下寻找泪小管鼻侧断端后,直接插入硅胶管或带线塑料管,10-0尼龙线端端吻合,3个月拔管。结果: 23例均1次寻找断端成功,其中2例因断端靠近泪囊,在上泪小管圆针引导下找到断端。拔管后随访3~6个月,治愈21例,好转1例,无效1例。结论: 在显微镜下寻找泪小管比较容易,直接插管简单,一期显微吻合成功率高。

Direct intubation and primary canaliculusostomy by microscopy for laceration of lower lacrimal canaliculus

Objective:To evaluate the clinical effect of direct lacrimal canaliculus intabation and primary canaliculusostomy under microscope for laceration of lower lacrimal canaliculus.Methods:The lacerated paranasal points of 23 patients were found under the microscope and intabated with a silica gel or plastic duct with a piece of silk through it.The two sides were sutured with nylon suture.Three months later,the tube was pulled out.Results:The lacerated points of lacrimal canaliculus in the 23 cases were found successfully at one time and two of them were with the help of a round needle from upper lacrimal canaliculus.During the follow up of 3 to 6 months,the lacrimal passages were unobstructed in 21 cases;stenosis occurred in one case and obstruction of lacrimal ducts in one case.Conclusions:Direct lacrumal canaliculus intabation and primary canaliculusostomy have the advantages of higher success rate and fewer complications.
