AIM: To discuss the clinical applications of methods to localize nasal cut ends and the effects of Z-plasty in the surgeries for lower eyelid longitudinal laceration combined with lower lacrimal canaliculi disruption.

METHODS: From September, 2010 to October, 2013, a total of 37 patients(37 eyes)with lower eyelid longitudinal laceration combined with lower lacrimal canaliculi disruption were operated for anastomosis of lacrimal canaliculi disruption and suture of lower eyelid longitudinal. Different methods to search for the nasal cut ends of lacerated lacrimal canaliculi, such as “under a microscope directly”, “guided by probing needle” and “pigtail curved probe”. Then, to repair lower eyelid longitudinal laceration with Z-plasty transposition flaps. Follow up was 3mo～2a after operation.

RESULTS: All nasal cut ends could be found successfully on 37 patients; Lacrimal duct unobstructed in 31 patients(83.8%), improved in 5 patients(13.5%), invalid in 1 patient(2.7%),the overall successful rate was 97.3%; the eyelids repair was satisfactory, small scars, the appearance and function was normal.

CONCLUSION: The nasal cut ends can be found successfully by “directly under a microscope”, “guided by probing needle” and “pigtail curved probe”; the effect of silicone drainage tube used as lacrimal canaliculi bracket is satisfactory; most patients gained excellent recovery for both appearance and function after Z-plasty.
