Abstract

BACKGROUND AND OBJECTIVES: Endoscopic intranasal dacryocystorhinostomy (DCR) has been used as a primary treatment of lacrimal obstruction and for revision of conventional dacryocystorhinostomy. The objective of this research is to look for the cause of DCR failure.
MATERIALS AND METHOD: The endoscopic revision procedures were performed on 20 patients with recurrent epiphora after endoscopic DCR with anterior and posterior sac approach from 1995 to 2001. A retrospective review of 20 endoscopic revision
procedures was done.
RESULTS: Sixteen patients (80%) with recurrent epiphora showed granulation on intranasal opening. Most (14 of 16) began to show granulation at 6 postoperative weeks. The most common site of granulation formation was superior to intranasal opening. CONCLUSION: Because granulation formation was the most common cause of failure, it is important to extubate a silicone tube at 6 postoperative weeks.
