Results of endoscopic dacryocystorhinostomy

Abstract

Objectives:Dacryocystorhinostomy (DCR) is a surgical procedure where an alternative pathway is created to drain an obstructed lacrimal system into the nasal cavity. This can be accomplished externally or via endonasal approach in which the lacrimal sac is connected directly to the nose by removing the layers of bone and mucosa to separate these two structures.Methods:The surgical outcome of endoscopic endonasal DCR was reviewed minimum 5 maximum 23 months in 22 cases with nasolacrimal duct stenosis. Pope-Merocel® and primer silicon tube was applied for preventing restenosis.Results:Stenosis occurred at 5 (%31.2) cases with Pope-Merocel® and silicon tube was inserted at a second stage. There is not any stenosis at the primer or secondary silicon tube inserted cases.Conclusion:The success rate of endoscopic DCR has become comparable with that of traditional external DCR. Advantages of the endonasal approach are excellent visualization, lack of incisional scar, less time consuming, saving the medial palpebral ligament and the lacrimal pomp mechanism. If necessary additional management of intranasal pathology can be performed simultaneously.
