Abstract

Canalicular lacerations can be the result of sharp or blunt trauma as well as burns of the facial region. The nasolacrimal duct may become obstructed as an after-effect of naso-orbital trauma. Main principles of surgical repair of the lacrimal system are reviewed with regard to the outcome of our own patients compared with the literature. Success rates in the primary repair of traumatic injuries of canalicular system are about 70 to 82 %. 14 of 20 patients who were managed between 1976 and 1980 in our department were cured permanently. 55 of 272 secondary reconstructions of canalicular obstructions (1976 - 1997) were caused by trauma. Conjunctivodacryocystorhinostomy with polyethylene or silicone tubes (1978 - 1999, n = 37, 21 traumatic) had success rates of 61 % and 72 %, respectively. 11 (4.8 %) of 228 dacryocystorhinostomies (1991 - 2000) were necessary as a result of traumatic injuries and achieved a success rate of 87.5 %. Canalicular lacerations need urgent primary repair with silicone intubation and special heed to the medial canthal tendon. The success rate of secondary reconstructions of traumatically caused tear-duct system obstructions depends on the microsurgical techniques that were used.
