Laryngopexy and lacrimal duct intubation are two common procedures used to treat lacrimal duct obstruction in infants and children, and parents often hesitate to choose between the two procedures and are unsure of how to choose. In simple terms, lacrimal duct exploration is to use a probe to enter the lacrimal duct from the upper opening of the lacrimal duct – the tear duct – and follow the natural course of the lacrimal duct to the lower opening of the lacrimal duct – the lower end of the nasolacrimal duct – to open up the obstruction point throughout the lacrimal duct. The probe does not remain in the tear duct for long, and is removed once it is passed. A lacrimal intubation is a silicone tube placed in the lacrimal duct immediately after the lacrimal duct exploration. The silicone tube can be left in the tear duct for a longer period of time and then removed when the tear duct is open. As you can see, lacrimal intubation is slightly more complicated than lacrimal ductal exploration, and there is the problem of removing the tube after the procedure. So why do we choose a complex procedure instead of a simple solution? Some parents of children who want to have a lacrimal duct exploration are also advised to choose a lacrimal intubation. What is the reason for this? Because the results of the procedure are different. If the child is young and has never been treated surgically, lacrimal drainage can be an option for the first surgery. However, if the child has undergone more than one lacrimal drainage procedure and the tear duct is still not open, or if the child is older, lacrimal intubation is recommended. Tear duct intubation is to implant a medical silicone tube with a diameter of only 0.6mm in the child’s tear duct, this silicone tube does not damage the eye, and is left in the tear duct to play a role in shaping and dilating support, after a period of time, the child’s tear duct is open, the damage caused by inflammation is repaired, and the symptoms improve and disappear, then the silicone tube can be removed. Removal of the silicone tube is simple and can be done under local anesthesia.
