4 15 Endoscopic Dacryocystorhinostomy Dcr Surgical Techniqueо Endoscopic dacryocystorhinostomy (dcr) is a surgical intervention for epiphora caused by obstruction of the nasolacrimal duct. understanding endonasal anatomy, wide endoscopic marsupialization of the lacrimal sac, and meticulous care of the nasal mucosa are important to achieve good results. patients develop symptoms of tearing when there is an. Dacryocystorhinostomy (dcr) is done to bypass obstruction of the nasolacrimal duct i.e. distal to the lacrimal sac, to re establish drainage of tears into the nasal cavity. it involves removing the bone between the lacrimal sac and the nasal cavity and anastomosing the mucosa of the lacrimal sac to the nasal mucosa (figure 1).

Considerations for an endoscopic dcr. endoscopic dcr is favored for most clinical situations, as the rate of success is as high as external dcr. external dcr can cause orbicularis and, therefore, lacrimal pump dysfunction, which may further worsen epiphora. biopsies of the sac mucosa can be performed via both techniques if adequate equipment is. 410 955 5000 maryland. 855 695 4872 outside of maryland. 1 410 502 7683 international. a dacryocystorhinostomy (dcr) is a type of surgery done to create a new tear drain between your eyes and nose. you may need this surgery if your own tear duct has become blocked. Dcr can be achieved through an external or internal endoscopic endonasal approach. although within the early literature, the reported success rate of external dcr was slightly higher than internal endoscopic, later studies have shown comparable rates of success. 1 3 this discrepancy is thought to be representative of individual surgeon experience and technique.
