The pigtail probe, revisited.

Choosing a method for repair of a canalicular laceration can be a challenge for the ophthalmic surgeon. Important principles to consider include direct anastomosis of the severed canalicular ends, endocanalicular support, and avoiding trauma to the uninvolved portions of the nasolacrimal system. The round-tipped, eyed pigtail probe has been found to be a safe, effective instrument in identifying and repairing a canalicular laceration. The authors also found it helpful in reconstructing partially excised canaliculi after tumor removal with Mohs' surgery. A high degree of anatomic and functional success was achieved using this instrument in a careful and meticulous technique.
