Abstract | OBJECTIVES: STUDY DESIGN AND SETTING: RESULTS: The rate of success after revisional surgery was 90.9%. The major causes of failure of the external approach were the presence of granulation tissue, septal deviations and synechiae near the opening of the fistula, inadequate removal of the bony wall adjuvant the lacrimal sac, technical error in the localization of the lacrimal sac, and excessive perioperative bleeding that impaired the surgical field. CONCLUSION: Endoscopic dacryocystorhinostomy in revisional cases proved to be a safe technique of low morbidity, permitting effective resolution of the lacrimal obstructions. SIGNIFICANCE: Endoscopic surgery allows greater visibility of the lacrimal sac and its neighbor anatomic alterations and leads to better results.
