目的探讨显微镜下泪小管断裂吻合术的疗效。方法 46例行泪小管吻合术患者于从上泪小管注入玻璃酸钠,寻找下泪小管鼻侧断端,以细硅胶管为支撑物在显微镜下吻合泪小管。结果 46例患者中术后45例泪道冲洗通畅,1例轻度溢泪,无一例吻合失败。结论自上泪小管注入玻璃酸钠寻找断裂下泪小管鼻侧断端,于显微镜下行泪小管断端吻合术是一种有效的治疗方法,术后并发症少,值得基层医院推广应用。
Objective To investigate the efficacy of microsurgical anastomosis of the canalicular laceration. Methods 46 cases of tracheal anastomosis were injected with sodium hyaluronate from the upper lacrimal duct, looking for the nasal end of the lacrimal canaliculus, and using the fine silicone tube as the support, the lacrimal duct was anastomosed under the microscope. Results Among the 46 patients, 45 cases had lacrimal duct patency and 1 case had mild spilled tears. None of the cases had anastomotic failure. Conclusion The injection of sodium hyaluronate from the canaliculus into the nasal septum to look for the rupture of the canaliculus is an effective method to treat lacrimal duct anastomosis under the microscope. There are few postoperative complications and it is worth popularizing and applying.
