title: Endoscopic evaluation and management of the lacrimal sump syndrome.
abstract: Failed dacryocystorhinostomy caused by the presence of residual lacrimal sac has been termed the "lacrimal sump syndrome." Epiphora occurs when tears collect in this residual pouch and lacrimal drainage is delayed. Irrigation into the nose may seem normal. This condition can be easily diagnosed with nasal endoscopy and has a characteristic radiologic appearance. Six patients with failed dacryocystorhinostomy caused by lacrimal sump syndrome were successfully treated with an endoscopic contact Nd:YAG laser technique. Endoscopic dacryocystorhinostomy using the contact Nd:YAG laser is an effective method for treating patients who have persistent epiphora or dacryocystitis after failed dacryocystorhinostomy.
