An 89-year-old woman presented with a canalicular-involving laceration/avulsion of the right lower eyelid after a fall. The inferior canaliculus was severed deep within the wound, and the ends were difficult to identify. Novel pigtail cannulas, designed by the authors, were used for lacrimal system intubation and suture passage. Satisfactory cosmetic and functional results were achieved. These cannulas facilitate repair by integrating multiple functionalities in a single instrument. Once a cannula has been inserted and rotated, the location of fluid egress provides important clues. If injected saline appears in the nasopharynx but not in the wound, absence of a common canaliculus can be suspected. Injection of viscoelastic, air or fluorescein-impregnated saline also permits easier identification of the cut end of the canaliculus within the wound and facilitates appropriate rotation of the pigtail.
