The study subjects were randomly divided into two groups. Group 1 included 30 patients who underwent EX-DCR, and group 2 included 30 patients who underwent TDL-DCR. Surgery success rates were determined by patency of the neo-ostium, with free saline flow on irrigation and the absence of epiphora.<\/jats:p><jats:p>Results There were 23 women (76.7%) and 7 men (23.3%) with a mean age of 47.33\u2009\u00b1\u200912.44 years in group 1, and 18\u00a0women (60%) and 12 men (40%) with a mean age of 46.2\u2009\u00b1\u200919.4 years in group 2. There was no significant difference between groups 1 and 2 with respect to age or gender (p\u2009=\u20090.801, p\u2009=\u20090.267, respectively). The mean duration of symptoms was 3.2 years, ranging from 1.5 to 5 years. The mean postoperative follow-up was 12.3\u2009\u00b1\u20092.44 months. At the end of the follow-up period, the surgery success rates were 96.7% (29\/30 eyes) in group 1, and 90% (27\/30 eyes) in group 2. There was no statistical difference in the surgery success rates between groups (p\u2009=\u20090.612).<\/jats:p><jats:p>Conclusion TDL-DCR is a minimally invasive and safe procedure. The lack of bleeding and incision scar and shorter operation time suggest that TDL-DCR can be a good alternative in PANDO patients.<\/jats:p>","DOI":"10.1055\/a-1720-1752","type":"journal-article","created":{"date-parts":[[2022,2,19]],"date-time":"2022-02-19T00:19:22Z","timestamp":1645229962000},"page":"799-803","source":"Crossref","is-referenced-by-count":4,"title":["Comparison of Outcomes of External Dacryocystorhinostomy and Transcanalicular Laser-Assisted Dacryocystorhinostomy in Patients with Primary Acquired Nasolacrimal Duct Obstruction"],"prefix":"10.1055","volume":"239","author":[{"given":"Demet","family":"Mutlu","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Kayseri City Education and Research Hospital, Kayseri, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nurettin","family":"Bayram","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Kayseri City Education and Research Hospital, Kayseri, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mustafa Kemal","family":"Arici","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Faculty of Medicine, Cumhuriyet University, Sivas, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ayse Vural","family":"Ozec","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Faculty of Medicine, Cumhuriyet University, Sivas, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Haydar","family":"Erdogan","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Faculty of Medicine, Cumhuriyet University, Sivas, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mustafa Ilker","family":"Toker","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Faculty of Medicine, Cumhuriyet University, Sivas, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2022,2,18]]},"reference":[{"key":"ref1","doi-asserted-by":"crossref","first-page":"1170","DOI":"10.1017\/S0022215107009024","article-title":"Endoscopic endonasal laser versus endonasal surgical dacryocystorhinostomy for epiphora due to nasolacrimal duct obstruction: prospective, randomised, controlled trial","volume":"121","author":"S Maini","year":"2007","journal-title":"J Laryngol Otol"},{"key":"ref2","doi-asserted-by":"crossref","first-page":"191","DOI":"10.3129\/i10-096","article-title":"Comparison of nonlaser nonendoscopic endonasal dacryocystorhinostomy with external dacryocystorhinostomy","volume":"46","author":"R A Walker","year":"2011","journal-title":"Can J Ophthalmol"},{"key":"ref3","doi-asserted-by":"crossref","first-page":"211","DOI":"10.1055\/a-1283-9271","article-title":"Tr\u00e4nenwegsstenosen im Erwachsenenalter","volume":"238","author":"J Heichel","year":"2021","journal-title":"Klin Monbl Augenheilkd"},{"key":"ref4","doi-asserted-by":"crossref","first-page":"179","DOI":"10.1097\/IOP.0b013e31804bdef9","article-title":"Transcanalicular dacryocystorhinostomy with diode laser: long-term results","volume":"23","author":"G Plaza","year":"2007","journal-title":"Ophthalmic Plast Reconstr Surg"},{"key":"ref5","doi-asserted-by":"crossref","first-page":"29","DOI":"10.1055\/s-0041-110133","article-title":"Die externe Dakryozystorhinostomie \u2013 eine Analyse des Krankenguts der Universit\u00e4ts-Augenklinik Halle der Jahre 2000\u20132011","volume":"233","author":"J Heichel","year":"2016","journal-title":"Klin Monbl Augenheilkd"},{"key":"ref6","doi-asserted-by":"crossref","first-page":"979","DOI":"10.2147\/OPTH.S19455","article-title":"A comparison of external and endoscopic endonasal dacryocystorhinostomy for acquired nasolacrimal duct obstruction","volume":"5","author":"R Karim","year":"2011","journal-title":"Clin Ophthalmol"},{"key":"ref7","doi-asserted-by":"crossref","first-page":"1488","DOI":"10.1001\/archopht.1992.01080220150037","article-title":"Endocanalicular laser-assisted dacryocystorhinostomy.
