泪小管断裂吻合的手术技巧及临床观察

Operative technique and clinical observation of anastomosis for disrupted canaliculus

目的 探讨断裂泪小管的找寻方法及手术吻合技巧,选择合适的泪管支撑管提高急诊泪小管断裂吻合术的成功率.方法 对2005年1月至2016年3月在安康市中医医院行显微镜下直接寻找断裂的泪小管鼻侧断端,以硬膜外导管或新型RS泪道管作为支撑吻合泪小管断端.结果 128例128只眼泪小管断裂（下泪小管断裂112例,上泪小管断裂16）中125例均成功吻合,未找到3眼行泪囊切开逆行插管法成功.结论 该方法是一种简便、易行、可靠、值得推广的泪小管断裂吻合方法.

Objective TTo study the fracture finding methods and inferior lacrimal canaliculns anastomosis techniques,choosing the right duct support tubes to improve success rate of anastomosis of the disrupted canaliculus in emergency.Methods Directly under the microscope,looking for broken ends of the lateral inferior lacrimal canaliculus fracture,using extradural catheter new RS for support broken lacrimal duct ends by anastomosis of lacrimal canal.Results Of 128 tears tubular break （112 cases of the lower disrupted canaliculus,16 upper disrupted canaliculus）,125 cases were anastomosis successfully,3 cases could not find lacrimal sac while using open retrograde intubation with success.Conclusions It is a simple,easy,reliable and worth promoting method for anastomosis of broken lachrymal canaliculus.
