title: Nasolacrimal injuries. Evaluation and management.
abstract: The tear drainage system is disrupted in 17% to 21% of nasoethmoidal fractures and, to a lesser degree, other midfacial fractures. When epiphora or dacryocystitis occurs, evaluation should include the Jones dye tests, probing of the ductal system, or dacryography. Dacryocystorhinostomy is the treatment of obstruction distal to the common canaliculus.
