title: Failed dacryocystorhinostomy: the sump syndrome.
abstract: A dacryocystorhinostomy may fail due to a problem along the canaliculus, at the ostomy site of nasolacrimal sac to nose, due to an intranasal problem or related to the stent. The "sump syndrome" occurs when a residual nasolacrimal sac forms, collects fluids, and leads to tearing. This entity, although uncommon, has a characteristic clinical history and radiologic appearance.
