This patient had an initially successful endoscopic DCR, but developed recurrent symptoms. The video demonstrates large and well-formed external ostium, but an internal ostium that has become occluded by a fibrotic membrane. The occlusion is carefully overcome and O’Donoghue tubes place to try to maintain patency.
