Patients who underwent revision DCR were excluded. The absence or improvement of symptoms as reported by the patients was defined as successful outcome. Conversely, recurrence of epiphora was considered as failure. The results were reviewed at 1 year in the clinic and at further 3 years and 5 years by telephone consultation.<\/jats:p><\/jats:sec><jats:sec><jats:title>RESULTS<\/jats:title><jats:p>There were 65 patients (73 procedures) in the study cohort, with a mean follow\u2010up period of 74\u00a0months (range, 60\u201397). Early failure was noted in 13 patients at 1 year. Only 28 patients (of the possible 50) were free from epiphora after 5 years postsurgery.<\/jats:p><\/jats:sec><jats:sec><jats:title>CONCLUSION<\/jats:title><jats:p>We found that the success rate of ELDCR has gradually declined over the years to 56% (confidence interval, 38\u201369) in patients who had at least 5 years of postoperative data. We do not advocate the use of laser in endonasal DCR for patients with epiphora.<\/jats:p><jats:p>EBM rating: C\u20104<\/jats:p><\/jats:sec>","DOI":"10.1016\/j.otohns.2006.02.006","type":"journal-article","created":{"date-parts":[[2006,7,1]],"date-time":"2006-07-01T09:40:19Z","timestamp":1151746819000},"page":"81-84","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Long\u2010Term Results of Endonasal Laser Dacryocystorhinostomy"],"prefix":"10.1002","volume":"135","author":[{"given":"Umapathy","family":"Neel","sequence":"first","affiliation":[{"name":"Departments of Otolaryngology Royal Shrewsbury Hospital Shrewsbury United Kingdom"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kalra","family":"Sukman","sequence":"additional","affiliation":[{"name":"Departments of Otolaryngology Royal Shrewsbury Hospital Shrewsbury United Kingdom"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"W.
