Prospective, randomised clinical trial on the necessity of using a silicone intubarium in the context of a dacryocystorhinostomy (DCR) in patients with postsaccal lacrimal duct stenosis

Background Endonasal endoscopic dacryocystorhinostomy (EN-DCR) is considered the gold standard for the treatment of (post-) saccal nasolacrimal duct (TNW) stenosis. This clinical prospective trial investigated the impact of silicone stents (SST) on EN-DCR success rates.
