Abstract:Objective To investigate the nasal stump search method and surgical anastomotic technique for ruptured inferior canaliculus,and to select a suitable lacrimal duct support tube to improve the success rate of anastomosis for ruptured inferior canaliculus. Methods A retrospective case analysis method was used to select 70 patients (70 eyes) of the lower lacrimal canalicular ruptures from June 2014 to 2018 in Wuxi People′s Hospital.The nasal end of the lower canaliculus was microscopically looked for during the operation,and the lower canaliculus was anastomosed by silicone ring-shaped tube placement in the lacrimal duct in stage I,which was performed to observe the clinical treatment effect and complication rate. Results All intraoperative anastomoses were successful in 70 cases (70 eyes) of ruptured lower lacrimal canaliculi.After the operation,there were 58 eyes (82.9%) healed,11 eyes (15.7%) improved and 1 eye (1.4%) did not heal,for an overall response rate of 98.6%. Conclusion Surgical treatment of lower canalicular tear with silicone ring canalicular anastomosis is a simple and easy anastomosis for lower canalicular rupture.
