Purpose: To evaluate the efficacy of endoscopic endonasal primary conjunctivodacryocystorhinostomy (CDCR) and revision CDCR after primary CDCR. Methods: Twenty-four patients who had undergone endoscopic endonasal CDCR with a Jones tube and who were followed up for over 6 months at our hospital were reviewed retrospectively. Our analysis included success rate, operation times, and causes of failure. Results: The indications for revision CDCR were Jones tube prolapse and inadequate tube length. The initial success rate in the primary and revision groups were 78.6% (11/14) and 100% (10/10), respectively, and their mean operation times were 24 min (± 6.3) and 21 min (± 6.1), respectively. Main causes of failure included inaccurate tube length and abnormal tube position. Conclusions: Endoscopic endonasal CDCR appears to be a reasonable revision and primary approach, because it allows Jones tube length to be measured accurately during surgery, and an 18- to 20-mm Jones tube length was used in most cases.
