目的探讨外伤性泪小管断裂吻合的手术技巧。方法在手术显微镜下应用直视法、逆行法寻找泪小管鼻侧断端,行插管吻合修复泪小管断裂,留置硬膜外腰麻管于泪道3个月,拔管后应用庆大霉素、地塞米松混合液冲洗泪道,局部滴妥布霉素地塞米松滴眼液。结果本组手术治愈率94.12%。结论泪小管断裂I期吻合成功率高,术中尽可能直视下寻找鼻侧泪小管断端。
Objective To investigate the surgical technique of traumatic lacrimal canaliculi anastomosis. Methods under the operating microscope under direct vision method, retrograde method to find the nasal end of the canaliculus punctatus, line intubation anastomosis lacrimal duct rupture, indwelling lumbar epidural anesthesia in the lacrimal duct for 3 months after extubation Gentamicin Su, dexamethasone mixture wash lacrimal duct, local drops of tobramycin dexamethasone eye drops. Results The cure rate of this group was 94.12%. Conclusions The successful rate of I-phase anastomosis of canalicular canal rupture is high, and it is necessary to look for the end of nasolacrimal canaliculus under direct vision as much as possible.
