This technique has been used for the treatment of recurrent lacrimal obstruction after failed external dacryocystorhinostomy (DCR) in 12 patients. Improved intranasal visualization with the endoscope allowed easy identification and opening of the lacrimal sac, with no need for a skin incision. Obstructing intranasal pathology, including adhesions from previous DCR, an enlarged middle turbinate, and ethmoid sinus disease, was readily identified and corrected. There were no intraoperative complications. Lacrimal obstruction was completely relieved in nine of 12 patients (75%), with a followup of 7 to 25\u00a0months. Endoscopic revision DCR should be considered in patients with recurrent epiphora after external DCR.<\/jats:p>","DOI":"10.1177\/019459989110400408","type":"journal-article","created":{"date-parts":[[2015,11,25]],"date-time":"2015-11-25T06:43:45Z","timestamp":1448433825000},"page":"473-479","source":"Crossref","is-referenced-by-count":115,"title":["Endoscopic surgery for lacrimal obstruction"],"prefix":"10.1002","volume":"104","author":[{"given":"Ralph","family":"Metson","sequence":"first","affiliation":[{"name":"Department of Otology and Laryngology Harvard Medical School Massachusetts Eye and Ear Infirmary Boston Massachusetts"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[1991,4]]},"reference":[{"key":"e_1_2_1_2_1","first-page":"385","article-title":"Nuovo metodo conservatore di cura radicale delle supporazioni chroniche del sacco lacrimale","volume":"10","author":"Toti A","year":"1904","journal-title":"Clin Med"},{"key":"e_1_2_1_3_1","doi-asserted-by":"publisher","DOI":"10.1288\/00005537-192105000-00002"},{"key":"e_1_2_1_4_1","doi-asserted-by":"publisher","DOI":"10.1288\/00005537-199012000-00020"},{"key":"e_1_2_1_5_1","first-page":"601","article-title":"Results of dacryocystorhinostomy: Analysis of causes for failure","volume":"93","author":"Welham RAN","year":"1973","journal-title":"Trans Ophthalmol Soc U K"},{"key":"e_1_2_1_6_1","doi-asserted-by":"publisher","DOI":"10.1097\/00002341-198804030-00004"},{"key":"e_1_2_1_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9394(71)90001-8"},{"key":"e_1_2_1_8_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF00153489"},{"key":"e_1_2_1_9_1","first-page":"486","article-title":"Dacryocystorhinostomy failure: Association with nasolacrimal silastic intubation","volume":"20","author":"Allen K","year":"1989","journal-title":"Ophthalmic Surg"},{"key":"e_1_2_1_10_1","doi-asserted-by":"publisher","DOI":"10.1001\/archotol.1982.00790550011003"},{"key":"e_1_2_1_11_1","first-page":"419","article-title":"Dacryocystorhinostomy without flaps","volume":"19","author":"Becker BB","year":"1988","journal-title":"Ophthalmic Surg"},{"key":"e_1_2_1_12_1","first-page":"427","article-title":"Results of dacryocystorhinostomy: Analysis of reoperations","volume":"11","author":"McLachlan DL","year":"1980","journal-title":"Ophthalmic Surg"},{"key":"e_1_2_1_13_1","doi-asserted-by":"publisher","DOI":"10.1136\/bjo.71.2.152"},{"key":"e_1_2_1_14_1","doi-asserted-by":"publisher","DOI":"10.1017\/S0022215100109405"},{"key":"e_1_2_1_15_1","doi-asserted-by":"publisher","DOI":"10.1177\/000348948609500618"},{"key":"e_1_2_1_16_1","doi-asserted-by":"publisher","DOI":"10.1001\/archopht.1990.01070050089038"}],"container-title":["Otolaryngology\u2013Head and Neck Surgery"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1177\/019459989110400408","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/aao-hnsfjournals.onlinelibrary.wiley.com\/doi\/pdf\/10.1177\/019459989110400408","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,10,20]],"date-time":"2025-10-20T14:04:12Z","timestamp":1760969052000},"score":1,"resource":{"primary":{"URL":"https:\/\/aao-hnsfjournals.onlinelibrary.wiley.com\/doi\/10.1177\/019459989110400408"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1991,4]]},"references-count":15,"journal-issue":{"issue":"4","published-print":{"date-parts":[[1991,4]]}},"alternative-id":["10.1177\/019459989110400408"],"URL":"https:\/\/doi.org\/10.1177\/019459989110400408","archive":["Portico"],"relation":{},"ISSN":["0194-5998","1097-6817"],"issn-type":[{"value":"0194-5998","type":"print"},{"value":"1097-6817","type":"electronic"}],"subject":[],"published":{"date-parts":[[1991,4]]}}}
