The facility we use for surgery of the lacrimal drainage system is the Department of Otorhinolaryngology and Head and Neck Surgery at University Hospital Ostrava. All procedures carried out there involve the use of endoscopes (Figs. 2.) and are conducted under general anesthesia. The attending personnel comprise ophthalmologist Stanislav Červenka, M.D., Ph.D. and two otorhinolaryngologists – Prof. Pavel Komínek, M.D., Ph.D., MBA and Petr Matoušek, M.D., Ph.D., MBA. Our data shows that, prior to 2020, over 4,000 instances of silicone intubation were performed (Figs. 1) in patients with congenital nasolacrimal duct obstruction, along with 2,000 dacryocystorhinostomy (DCR) procedures, mostly utilising an endonasal approach (EDCR). We have also performed more than 300 instances of conjunctivodacryocystorhinostomy (CDCR). Such a high number of operations is unique in the Czech Republic and even from an international perspective. The results of treatment are continuously evaluated, in addition to being published in articles in scientific journals and detailed in presentations at medical conferences across the world (see S. Červenka, M.D., Ph.D. – Publications).
