Among them, dacryostenosis had been documented in 35 eyes by dacryocystography. The Tm:YAG procedure involved the administration of local anesthesia, after which a 600-\u03bcm laser fiber was inserted into the lacrimal canaliculi and then into the nasolacrimal duct. Under endoscopic visualization, the DCR was performed anterior and inferior to the middle turbinate, which created an opening. Silicone stents were then inserted and tied intranasally. In the immediate postoperative period, all 27 patients noted initial improvement. During a follow-up of 22 days to 25 months (mean: 11.3 mo), 24 of the 27 patients (89%) remained symptom-free, while the remaining 3 patients (11%) experienced a treatment failure and required revision surgery. To the best of our knowledge, only two articles on thulium laser therapy for DCR have been previously published, both approximately 25 years ago; both involved the use of a thulium along with holmium and chromium in cadavers. As far as we know, our case series is the largest in the English-language literature that has documented the use of the thulium in laser therapy for DCR, and it is the only in vivo study. We found that DCR with the Tm:YAG laser was an effective and affordable option for patients with symptomatic epiphora secondary to lacrimal obstruction.<\/jats:p>","DOI":"10.1177\/014556131809700808","type":"journal-article","created":{"date-parts":[[2018,12,4]],"date-time":"2018-12-04T23:50:02Z","timestamp":1543967402000},"page":"E39-E42","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Dacryocystorhinostomy with a Thulium:YAG Laser\u2014a Case Series"],"prefix":"10.1177","volume":"97","author":[{"given":"Christopher","family":"Tang","sequence":"first","affiliation":[{"name":"From the Department of Head and Neck Surgery, Kaiser Permanente Medical Center, San Francisco"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Scott","family":"Rickert","sequence":"additional","affiliation":[{"name":"Pediatric Voice Center, New York University Lagone Medical Center, New York City"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Niv","family":"Mor","sequence":"additional","affiliation":[{"name":"Division of Head and Neck Surgery, Maimonides Medical Center, Brooklyn, N.Y."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrew","family":"Blitzer","sequence":"additional","affiliation":[{"name":"New York Center for Voice and Swallowing Disorders, New York City"},{"name":"Department of Otolaryngology\u2013Head and Neck Surgery, Columbia University Medical Center, New York City."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Martin","family":"Leib","sequence":"additional","affiliation":[{"name":"Orbit and Ophthalmic Plastic Surgery Service, Edward S.
