Abstract. We reviewed 12 cases who needed another surgery after failed external dacryocystorhinostomy. Obstruction recurred within 3 months after surgery. By dacryocystography using computerized tomography(CT),the ethmoidal sinus was located between the lacrimal fossa and the nasal cavity in 73% of cases. This feature appeared to be the major cause of granular proliferation obstructing the bony ostium. Too inferiorly placed ostium seemed to have induced recurrence due to involvement of the ethmoidal sinus. Atresia of lacimal canaliculus was present in one case and abnormal nasal cavity in another. Due attention to the above possibilities is advocated to achieve success in external dacryocystorhinostomy.
