[Value of spiral CT in the diagnosis of nasolacrimal duct stenosis].

PURPOSE: This study was to evaluate postdacryocystographic spiral CT in the diagnosis of stenoses of the nasolacrimal duct system.

PATIENTS AND

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.

CONCLUSION

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