Abstract
Recanalization of the lacrimal ducts (LD) is a low-trauma surgical intervention aimed at restoring their patency. However, the need to use a lacrimal stents (LS) during the intervention is associated with a number of possible intra- and postoperative complications.

Purpose: the aim of the study is to develop a modification of the recanalization of the nasolacrimal duct in patients with complete acquired obstruction of the nasolacrimal duct, during which subsequent installation of a silicone LS is not required to maintain patency of the nasolacrimal duct in the postoperative period.

Material and methods: the study included 5 patients (5 cases) with primary postsaccal obliteration of the nasolacrimal duct, who underwent complex treatment according to our proposed method, aimed at restoring the patency of the nasolacrimal duct. The postoperative observation period was 6 months. The anatomical and functional results were assessed using both subjective (determination of the severity of lacrimation according to the Munk scale) and objective criteria (tests with fluorescein, rinsing the nasolacrimal duct, performing rhinoendoscopy).

Results: in all cases, anatomical and functional patency of the LD was achieved. No intra- or postoperative complications were noted during the study.

Conclusion: in order to reduce the likelihood of complications associated with the insertion and placement of the LS in the lumen of the LD, during recanalization, subsequent introduction of viscoelastic is possible as an alternative to the silicone LS.

Keywords: lacrimal drainage system, recanalization, viscoelastic
