BACKGROUND: The treatment strategy for canalicular obstruction in adults begins with probing and irrigation of the system. If stenosis persists, redilation and irrigation may work, but dacryocystorhinostomy (DCR) is often necessary. However, DCR is an invasive surgical procedure. The placement of monocanalicular stents have shown to be an alternative in the treatment of canalicular obstruction.
CASE REPORT(S). Three cases of monocanalicular intubation with stents for the treatment of canalicular obstruction will be described. Results and complications of monocanalicular stent placement will be reviewed. In addition, the advantages of stent placement over invasive surgical procedures will be discussed.
CONCLUSIONS. The placement of monocanalicular stents in treating patients with canalicular stenosis is a viable alternative to more invasive procedures such as DCR. This method was successful in treating passive obstruction of the inferior canaliculus in our three patients.
