[Endonasal microsurgical treatment of lacrimal duct stenoses. Indications, technique and results]

In a retrospective study we examined the indications, results and complications of endonasal microscopic dacryocystorhinostomy. Eighty-five operations were evaluated. Surgical success was proven in 83% for all indications using a combination of subjective judgement and objective findings. For the so-called classic indications--postsaccal stenosis, functional stenosis dacryolith and acute empyema--the operation was successful in 91% of cases. There were no permanent side effects.
