We perform the lacrimal drainage system surgery at the Department of Otorhinolaryngology and Head and Neck Surgery of University Hospital Ostrava. All the procedures are performed in general anaesthesia in cooperation of the ophthalmologist Stanislav Červenka, M.D., Ph.D. and the otorhinolaryngologists Prof. Pavel Komínek, M.D., Ph.D., MBA and Petr Matoušek, M.D., Ph.D. with standard use of endoscopes (Fig. 1, 2). Up to 2016 we have performed over 3.200 silicone intubations in patients with congenital nasolacrimal duct obstruction and over 1.500 dacryocystorhinostomies (DCR) mostly from the endonasal approach (EDCR). We have also performed more than 250 conjunctivodacryocystorhinostomies (CDCR). The number of surgeries is unique in the Czech Republic and one of the highest also in international context. The results of the treatment are continuously evaluated and presented as articles in scientific journals and presentations at both national and international congresses (See S. Červenka, M.D., Ph.D. – Publications).
