| Abstract: | Between April 1994 and October 1996 on account of complicated obstruction of the lacrimal pathways temporarily into the lacrimal efferent system 144 silicone cannulas were inserted in 127 children aged 4 months to 9 years. A standard procedure was used, with the children under general inhalation anaesthesia, in collaboration of an ophthalmologist and otorhinolaryngologist using endonasal optics. By October 1996 100 cannulas were extubated, on average after 4.1 months. The effectiveness of the procedure evaluated on the basis of clinical manifestations and the Dye Disappearance test is 81%. |
