    Purpose. To evaluate the results of cone–beam computed tomography of the paranasal sinuses with simultaneous contrast with a solution of tear ducts, using the proposed method, in patients with chronic dacryocystitis.

    Material and methods. In 23 patients (23 eyes) with chronic purulent dacryocystitis, CBCT of ONP with simultaneous contrast of tear ducts with a colored solution was performed for diagnostic purposes. Then, all patients underwent transcanalicular laser endoscopic dacryocystorinostomy (TLED).

    Results. CT scans obtained using a colored contrast solution showed an informative picture due to the maximum filling of the tear ducts, which was also visually confirmed by the appearance of a blue solution from the lacrimal point.

    Conclusion. The effectiveness of the proposed tear ducts contrast method was confirmed by the analysis of tomographic images taking into account the individual characteristics of each patient and subsequent successful (in 100% of cases) TLED using various stenting options.
