  • Title: [Value of spiral CT in the diagnosis of nasolacrimal duct stenosis].
    Author: Hähnel S, Jansen O, Zake S, Sartor K.
    Journal: Rofo; 1995 Sep; 163(3):210-4. PubMed ID: 7548866.
    Abstract:
    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.
