AIM:To observe the results of neotype tractus lacrimalis drainage system for the treatment of lacrimal duct obstruction and canaliculus breakage.METHODS:One hundred and six cases with chronic dacryocystitis or nasolacrimal duct obstruction were performed the inverse ball silicone tube implantation in nasolacrimal canal.Lacrimal passages were douched regularly after operation and 3-6 months tube was extubated;88 cases with lacrimal duct obstruction and traumatic canaliculus breakage were implanted ring silicone tube in nasolacrimal duct,and 6-12 months tube was extubated.RESULTS:Five cases with nasolacrimal duct obstruction,4 cases with chronic dacryocystitis,3 cases with lacrimal duct obstruction recurred epiphora,the other cases have no recurrent.Lacrimal passages flush was unobstructed after surgery.CONCLUSION:Neotype tractus lacrimalis drainage system for the treatment of lacrimal duct obstruction and canaliculus breakage is an effective,simple process,and have the advantages including mini-traumato-architecture,no part or system adverse reaction,worthy clinical genera-lization and application.
