[Application of the Ritleng intubation lacrimal system for the surgical treatment of combined lesions of lacrimal passages].

A total of 46 patients suffering persistent lacrimation were available for examination. Chronic catarrhal dacryocystitis was diagnosed in 19 (41.3%) of them and chronic purulent dacryocystitis in the remaining 27 (58.7%). All the patients presented with lacrimal duct obstruction. Surgical treatment included mucroscopic endonasal canaliculocystorhinostomy with intubation of lacrimal passages using the Ritleng system. After the completion of the one-year dynamic follow-up period and removal of the stent from the lacrimal passages, results of the treatment were described as positive in 42 (91.3%) patients and as negative in 4 (8.7%) cases.
