Description

<p>Dacryocystorhinostomy (DCR) is a surgical approach for the treatment of nasolacrimal duct obstruction, and endoscopic DCR (E-DCR) has become more and more popular in recent years. Since postoperative anastomosis stenosis or blockade is one of the major complications of this surgery, prevention is critical. Herein, we introduce our modification of E-DCR to reduce this complication and report the outcomes.A total of 73 sides in 65 patients underwent E-DCR between July 2010 and April 2016 and were followed up for 12 months. The initial goal of this surgery was to complete 0- or 70-degree endoscopic view of the common internal punctum in an opened lacrimal sac prior to November 2013 (the conventional method), which was revised to obtain a field of view including both the fornix of the lacrimal sac and common internal punctum under 0-degree endoscopy after November 2013, after drilling and unifying the agger nasi cell and lacrimal sac (the modified method). Anatomical success was defined as the condition in which drainage of the opened lacrimal sac was achieved and functional success was defined as no recurrence of clinical symptoms, i.e., dacryorrhea.Anatomical success was achieved in 40 (87%) of 46 sides and functional success was observed in 38 (84%) using the conventional method. Meanwhile, Anatomical success was achieved in all (100%) of 31 cases and functional success was observed in 30 (97%) using the modified method. For anatomical success, there was a significant difference between the two groups.We conclude that wide opening of an anastomosis site, to the extent that the agger nasi cell is opened and unified with the lacrimal sac, is critical for better outcomes of E-DCR.</p>
