AIMS: To examine the surgical outcome of external dacryocystorhinostomy (DCR) with eight-flap @entity254 (8-flap ex-DCR). METHODS: A retrospective chart review was performed for 55 sides of 51 @entity1 with nasolacrimal duct obstruction who underwent 8-flap ex-DCR. The @entity1 were followed up postoperatively at 1, 2, 4, 8 and 12 weeks, and evaluations were continued with 12-week follow-ups until postoperative 12 months. Anatomical success was defined as no reflux on lacrimal irrigation at 12 months. Functional success was defined as no @entity9467 at postoperative 12 months. The presence of @entity1415 and postoperative surgical site infections were checked in all @entity1 . The presence of granulation tissue around the ostium, under nasal endoscopy, was also examined on 14 sides of 14 @entity1 , at each visit. RESULTS: Anatomical success was demonstrated on all sides, and functional success was obtained from 54 sides (98.2%) of 50 @entity1 . One @entity1 experienced postoperative intermittent @entity9467 on one side. The @entity1 did not show granulation tissue, @entity1415 or @entity281 throughout the observation period. CONCLUSIONS: The 8-flap ex-DCR showed complete anatomical success and favourable functional success with no @entity260 .
