下泪小管断裂吻合术55例临床观察

目的：探讨下泪小管断裂伤术中泪小管鼻侧断端的简单有效的寻找方法及下泪小管断裂吻合术后的疗效评价。

方法：下泪小管断裂伤患者55例55眼采用在手术显微镜直视下或自上泪小点注入生理盐水必要时注射玻璃酸钠的方法寻找断裂的下泪小管的鼻侧断端。以0.8mm外径空心硅胶软管作为支撑物吻合泪小管周围组织2～3针，硅胶软管留置2～3mo。术后随访6～24mo。

结果：下泪小管断裂患者55例55眼均吻合成功。其中治愈49例(89.1%)，好转5例(9.1%)，无效1例(1.8%)。

结论：该方法是一种行之有效操作简单疗效确切的泪小管断裂吻合方法，适合在有显微手术条件的医院采用。

Clinical observation of 55 cases of lower lacrimal canaliculi laceration anastomosis

AIM: To investigate a simple and effective method of lacrimal canalicular laceration of lacrimal canalicular nasal side in the broken end of the lower lacrimal canaliculus and to evaluate the curative effect after lower lacrimal canaliculi laceration anastomosis.

METHODS: In 55 cases(55 eyes)of lower lacrimal canalicular laceration patients, in order to look for nasal fracture of lower lacrimal canaliculus broken end. Most of them were under direct vision using surgical microscope, only a few patients injecting physiological saline(or sodium hyaluronate when necessary)from the upper lacrimal puncta. With 0.8mm outer diameter hollow silicone tube as the support material to anastomose surrounding tissue of the lacrimal canaliculus 2-3 needles. Silicone tube was indwelled for 2-3mo. All patients were followed up 6-24mo.

RESULTS: In 55 cases(55 eyes)of lower lacrimal canalicular laceration patients were all successful anastomosed. The cure rate and the effective rate were 89.1%(49/55), 9.1% cases improved(5/55), only 1 case was invalid(1.8%).

CONCLUSION: This method is an effective method of lacrimal canaliculus anastomosis operation and it is simple and effective, suitable for application in a hospital with micro operation conditions.
