Follow-up period ranged from 13 to 30 months (average, 17.5 months; SD, 6.8 months). \u201cSurgical success\u201d was defined as complete relief of epiphora and patent surgical ostium on endoscopic assessment.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Surgical success was achieved in 30\/35 (85.7%) patients after the primary surgery. Of 5 unsuccessful patients who complained of occasional epiphora, 4 patients had formed stenosis and 1 patient had granulation around the surgical opening, and all had revision surgery. Four of 5 (80.0%) patients achieved surgical success. Thus, including the result of revision surgery, 34\/35 (97.1%) patients were successful.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Posterior lacrimal sac approach in endoscopic DCR has several advantages: good sac accessibility, a low complication rate, and a relatively high success rate.
