ObjectiveTo observe the clinical effects of self-made epidural anesthetic catheter in the treatment of canalicular laceration. MethodsA total of 40 patients with canalicular laceration were selected, searching the broken end of the lacrimal ductule at the nasal side through a microscope, and quickly and successfully inserting epidural anesthetic catheter as the holder guided by the self-made epidural anesthetic catheter. After operation, the patients were treated with anti-inflammation, anti-swelling and prevention of infection. The patients were observed for the presence of ectropion, crack or ectropion of lacrimal punctum, and epiphora, etc., and the operative results were evaluated. ResultsA total of 36 patients had no epiphora after the holder remove. The total cure rate was 90% (36/40). Two patients with lower canalicular laceration complicated with a severe laceration of lower eyelid had ectropion of lower eyelid and lacrimal punctum after operation; 1 patient had the crack of lacrimal punctum 3 days after operation, and 1 patient with canalicular laceration and severe fracture of the nasal bone, because the holder was not completely implanted into the canalis nasolacrimal, the holder prolapse occurred after 2 weeks. The 4 patients mentioned above all had epiphora in the latter stage. ConclusionGuided by the self-made epidural anesthetic catheter, the holder can be inserted to the canalis nasolacrimal quickly and successfully. The epidural anesthetic catheter is convenient and cheap. As the holder of lacrimal passage, it not only improves the efficiency of operation, but also reduces the financial burden of patients. It is a feasible method in poor areas and basic hospitals.
