[Value of dacryocystography in localization diagnosis of lacrimal duct stenosis].
OBJECTIVE
Evaluation of dacryocystography in the preoperative localisation of stenosis of the lacrimal passage.


METHODS
The lacrimal system of 20 patients (25 eyes) suffering from lacrimal passage obstruction was examined either by conventional (n = 20) or by digital (n = 5) technique. Diagnostic imaging was evaluated concerning topographic Information of the pathologic lacrimal system, localisation of the level and differential diagnosis of the cause of the obstruction.


RESULTS
Cause of the obstruction was chronic dacryocystitis (n = 16), dacryolithiasis (n = 1), atresia of the lacrimal duct (n = 2), posttraumatic lesions (n = 3), rhinosinusitis (n = 1) and carcinoma of the maxillary sinus (n = 1). In 23 of 25 cases (92%) we found an exact correlation between dacryocystography and the intraoperative findings. The variation of stenosis types as well as different examination techniques are presented and compared with literature findings.


CONCLUSIONS
Dacryocystography is a valuable method in the diagnosis and preoperative planing in lacrimal system obstruction.
