Abstract
- PURPOSE
The purpose of this study was to evaluate the effects of revision endoscopic endonasal dacryocystorhinostomy (EDCR) and the causes of postoperative failure after primary endoscopic DCR in patients with nasolacrimal duct obstruction. METHODS: This prospective study enrolled 32 patients (32 eyes) who had undergone revision of endoscopic DCR with the diagnosis of obstruction of nasolacrimal system after primary EDCR between October 1997 and February 2003. RESULTS: The most common cause of revision operation after primary EDCR was granuloma, followed by membranous obstruction and common canalicular obstruction. The success rate of the cases with granuloma was 69.2%, and that with membranous obstruction was 100%. CONCLUSIONS: Revision EDCR success rate can be improved by reducing the frequency of granuloma as this was the most common factor for revision EDCR. The effect of antimetabolites in revision EDCR success rate is to be further evaluated.
