The hollow Ritleng probe was inserted via the canaliculus into the inferior meatus. The Sutupak thread-guide, attached to the silicone tube, was advanced through the probe lumen and retrieved using a hook under endoscopic visualization. The tube ends were tied to each other and tube removal was planned after 3 months. Absence of watering, discharge, and matted lashes after removal of silicone tube was defined as success.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      One hundred and fifty-two eyes of 152 children with a mean age of 3.26 \u00b1 2.3 years were included in the study.
