An improved canalicular laceration anastomosis surgery

Objective To investigate an improved anastomosis surgery for canalicular laceration.Methods In this study,double probe silicon stent with the knot was performed as an inproved method for canalicular laceration anastomosis surgery.The medical records of 45 cases with canalicular laceration were retrospectively analyzed.These patients were divided into three groups based on different surgical methods.The patients in group A underwent anastomosis combined with lumbar anesthesia catheter fixed on the eyelid.The patients in group B accepted double probe silicon stent.The surgery method for group C was similar with that for group B except the tube with the knot close to the punctum(the improved method by the author).The operative time and success rate of surgery were compared among three groups and the follow up time was 3 months.Results The method improved by author (silicon tube with knot) was safe with short operative time.The success rates of indwelling tube and surgery in improved group were higher than lumbar anesthesia catheter group,but similar with that in double probe silicon tube group.Conclusion For canalicular laceration without severe nasolacrimal duct injury,anastomosis can be performed with silicon tube as the stent combined with a knot close to the punctum.This improved anastomosis method is very suitable for emergent surgery.
