Original publication title: Canaliculorhinostomy as a treatment for nasolacrimal duct obstruction in dogs and cats.
Plain-English summary
A group of 11 dogs and 2 cats with tear drainage issues underwent a procedure to create a new tear duct system using silicone tubing. This method involved placing the tubing through the eye's drainage system into the nasal cavity, allowing tears to flow properly again. After the surgery, all pets had successful outcomes, with their tear drainage restored and only mild complications reported. The pets wore Elizabethan collars for a short time, just until their stitches were removed.

Abstract
OBJECTIVES: To create a replacement nasolacrimal system, using the puncta and canaliculi, with prolonged implant retention and minimal use of Elizabethan collars or other restraint devices. MATERIALS AND METHODS: The method was used in 11 dogs and two cats. Silicone tubing was placed through both canaliculi and, via a drill hole, into the nasal cavity. Distally, the tubing ends were tied in a subcutaneous pocket lateral to the premaxilla. Tubing retention time was 4 to 7 months. Elizabethan collars were used only until skin suture removal at 2 weeks. RESULTS: In all animals, a functional nasolacrimal system was re-created and remained patent over prolonged follow-up periods. Adverse effects and complications were mild. CLINICAL SIGNIFICANCE: The described method is relatively straightforward, thereby making relief of tear outflow problems widely accessible.
