目前治疗泪道上部断裂除手术修复外尚无理想的方法。因此如何提高新鲜伤口泪小管吻合的成功率以及伤后较长时间修复接通,确实是比较困难的问题。现就我院近二年收治的5例分析报告如下: 例1:汪某,男,23岁。右下睑被铁钉崩伤伴下泪小管断裂,伤后2天住院,入院当天下午在局麻下行伤口探查术,术中发现伤口组织破碎、水肿、出血,泪小管断端标志不清,先用圆锥形扩张针,扩张泪点和远端泪小管,鼻侧泪小管难以确定。将伤口从深部向泪囊部分离,暴露内眦韧带并予切断,显示泪囊,从前壁切开泪囊,找到泪囊处泪总管的开口,用60mm1/2圆针穿上3个“O”羊肠线,将针孔一侧从泪总管开口处穿出至鼻侧断端泪小管,拉出羊肠线的一端,再用硬膜外麻醉穿刺针从泪小点插入,然后将3个“O”羊肠线引出泪小点外(如图Ⅱ图Ⅲ),再将羊肠线两 The current treatment of upper lacrimal duct tears in addition to surgical repair there is no ideal way. Therefore, how to improve the success rate of fresh wound tracheal anastomosis, as well as a long time after injury repair connected, is indeed a more difficult issue. Now my hospital admitted in the past two years, five cases analyzed as follows: Example 1: Wang Mou, male, 23 years old. Right lower eyelid was nailed with nail injury and tear canal rupture, hospitalized 2 days after injury, on the afternoon of admission to local anesthesia wound exploration, surgery found wound tissue crushing, edema, bleeding, The first conical dilation needle, dilatation of the punctum and distal lacrimal duct, nasal lacrimal duct difficult to determine. The wound from the deep part of the lacrimal sac to expose the posterior cruciate ligament and to be cut off, showing lacrimal sac, lacrimal sac incision from the anterior wall to find the lacrimal sac at the opening of the tear tube, with 60mm1 / 2 round needle to wear 3 “O ”Catgut, the pinhole side of the tear from the opening to the nasal lacrimal duct piercing the end of the canaliculus, pull out the gut end, and then epidural anesthetic puncture needle inserted from the punctum, and then 3 A “O” catgut leads to tears outside the small point (Figure II Figure III), then the catgut two
