Microscope-Assisted Reconstruction of Canalicular Laceration Using Mini-Monoka

초록

A canalicular laceration is the most common injury of the lacrimal drainage system and can result from direct or indirect injury to the canalicular system. If the wounds are not managed properly, they can lead to scarring, stenosis, and inflammation, which may lead to symptomatic epiphora. We successfully reconstructed canalicular lacerations using Mini-Monoka tubes (FCI Ophthalmics, Marshfield Hills, MA) under microscopic magnification. We treated 14 patients for canalicular lacerations at the Soonchunhyang University Bucheon Hospital between August 2009 and October 2012. All patients underwent placement of a Mini-Monoka tube and a mucosal canalicular anastomosis microscopically to reconstruct monocanalicular lacerations. The tubes were removed at 6 to 8 months postoperatively, and follow-up was 8 to 12 months. No complications related to the Mini-Monoka tube, such as punctual plug migration, eye irritation, inflammation, granuloma formation, or erosion, occurred during the follow-up period. The goal of reconstructing a lacerated canaliculus is accurate approximation of the injured end of the canaliculus to facilitate mucosal healing and to prevent a canalicular obstruction. We believe that microscopic canalicular reconstruction with a Mini-Monoka tube is a safe, reliable, and straightforward method with fewer complications and is more effective for preventing iatrogenic injury in the unaffected canaliculus and minimizing patient discomfort.
