Abstract: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.
