The efficacy of double-passage lacrimal stent intubation for traumatic both upper and lower lacrimal canalicular laceration

Objective To evaluated the efficacy of the double-passage lacrimal stent intubation for traumatic both upper and lower lacrimal canalicular laceration under lacrimal endoscopy. Methods The clinical data of 21 eyes of 21 cases with lacrimal canalicular laceration form Jan. 2010 to Jun. 2015 were collected and analyzed retrospectively. All cases were performed with double-passage lacrimal stent intubation. The nasal end of lacrimal canaliculus was found under microscope. Lacrimal duct was probed in lacrimal passage to the nasal cavity guided by memory wire, intubating double-passage lacrimal stent as a support and end-to-end anastomosis. It tied a knot in the lower nasal passages. The lacrimal stent was removed 3-6 months after surgery. The efficacy of lacrimal canalicular was observed under lacrimal endoscopy and the follow-up time was 6 months-1 year. Results Seventeen cases (80.95%) were cured, the mucosa condition remained regular and lacring passage irrigation smooth. The stimulation of tears and mucosa condition remained narrow with a fiber wall attachment at lacrimal passage in 2 cases (9.52%). The lacrimal duct obstruction occurred in 2 cases. The obstruction of lacrimal duct was treated by laser surgery, they were cured after reimplantation of double passage lacrimal stent. Conclusion The double-passage stent intubation for the traumatic both upper and lower lacrimal canalicular laceration, obtains few complications, good efficacy and normal appearance. Under lacrimal endoscope, lacrimal small lesions, perform laser tratment in a targeted manner and prevent further obstruction can be observed directly.
