目的评价显微镜直视下下泪小管断裂吻合手术的效果。方法在显微镜直视下,采用筛前神经及滑车神经阻滞麻醉,以硬膜外麻醉导管为支撑的吻合方法治疗新鲜泪小管断裂54例,保留插管2～3个月,拔管后随访6个月。结果 52例排泪正常,无溢泪,冲洗泪道通畅,泪点无外翻,睑缘无畸形。结论在显微镜直视下下泪小管断裂吻合术以断端解剖位置为依据,目的明确,减少对局部组织的损伤,以硬膜外麻醉导管支撑,采用神经阻滞麻醉,减少局部浸润麻醉所造成的组织水肿,有助于寻找泪小管断端。
Objective To evaluate the effect of lacrimal canaliculi anastomosis under microscope. Methods Under the microscope, the anastomosis of anterior ethmoidal nerve and trochlear nerve block was used to treat 54 cases of fresh lacrimal canaliculus rupture with epidural anesthesia catheter. The catheter was retained for 2 to 3 months and followed up after extubation 6 months. Results 52 cases of normal lacrimal tears, no tears, irrigation lacrimal patency, no eversion of punctate, eyelid deformity. Conclusions Under the microscope, the anastomosis of lacrimal canaliculus rupture is based on the anatomical position of the broken end, and the purpose is clear, reducing the damage to the local tissue, using epidural anesthesia for catheter support, using nerve block anesthesia and reducing local infiltration anesthesia The tissue edema, helps to find the canaliculus.
