AIM:To apply a new type canaliculus breakage finding apparatus in treating the complicated lacrimal canaliculi laceration. METHODS:Fifty-five cases with complicated traumatic lacrimal canaliculi laceration were treated by new type canaliculus breakage finding apparatus. RESULTS:After the follow-up of 6-12 months,49 cases (89%) obtained the anatomic reposition with unobstructed irrigation, without self-lacrimatoin. 3 cases (7%) got light self-lacrimation and little obstructed irrigation, and 2 cases (4%) got obstructed irrigation. CONCLUSION:The therapeutic method with a new type canaliculus breakage finding apparatus is an effective treatment for complicated lacrimal canaliculi laceration.
