[Value of spiral CT in the diagnosis of nasolacrimal duct stenosis].
OBJECTIVE
This study was to evaluate postdacryocystographic spiral CT in the diagnosis of stenoses of the nasolacrimal duct system.


METHODS
Dacryocystography and postdacryocystographic spiral CT were performed in 11 patients with epiphora.


RESULTS
Postdacryocystographic spiral CT results in detailed information about the nasolacrimal duct system. Localization, degree, and aetiology of stenoses can be determined more reliably than with dacryocystography alone.


CONCLUSIONS
Postdacryocystographic spiral CT improves planning surgical or radiological interventions such as balloon dacryocystoplasty of the nasolacrimal duct.
