The most common anatomical causes of a dacryocystorhinostomy failure are inadequate osteotomy, ostium malpositions, inadequate lacrimal sac marsupialization, and cicatrical closure of the created ostium. They are the same in the external dacryocystorhinostomy and endoscopic dacryocystorhinostomy groups. Meticulous endoscopic evaluation to identify causative factors for failure and addressing them is crucial for subsequent successful outcomes. For the last 2 decades endoscopic dacryocystorhinostomy procedure evolved to reach the success percentage as high as the external dacryocystorhinostomy and to become the preferred technique for the revision surgery for the many lacrimal surgeons.
