显微镜下泪小管断裂吻合术的临床分析

Clinical analysis of canalicular anastomosis in traumatic lacrimal canaliculi fracture under suergical microscope

目的探讨创伤性泪小管断裂的手术治疗方法。方法在显微镜下寻找泪小管断端并置入硬膜外麻醉导管于泪小管及鼻泪管,吻合断裂泪小管。结果随访6个月-1年,84例患者一次治愈81例(96.4%),1例手术后第1天因麻醉导管置入位置异常,再次手术治愈,1例好转,1例未愈。80例置入麻醉导管到鼻泪管,4例置入于上下泪小管,其中2例用丝线作为支撑物。结论在手术显微镜下应用硬膜外麻醉导管治疗创伤性泪小管断裂方便、快捷,成功率高。

Objective To investigate the operative methods of using anesthetic duct as supporter for traumatic lacrimal canaliculi fracture. Methods 84 cases of fractured lacrimal canaliculi were jointed using the anesthetic duct as supporter under surgical microscope.Results All cases were follow-up for 6-12 months,the once success rate is 96.4% in 84 cases,anesthetic duct of one case was replanted after the first day of surgery because of the abnormal position. Later the patient recovered after operation. The upside lacrimal canaliculi and the downside lacrimal canaliculi of four case were jointed,Of the four cases,two patients use silk thread as surporter.One patient were unsucessful.Conclusion The canalicular anastomosis for traumatic lacrimal canaliculi fracture using anesthetic duct as supporter under suergical microscope is an easy、effective and successful method.
