However, physicians may encounter patients with a history of CL surgery who develop considerable postoperative changes that may lead to diagnostic confusion in imaging evaluation; increase the difficulty of future surgery, such as sinonasal surgery; and increase the incidence of future intraoperative complications. Case summary: A 67-year-old man with a surgical history of chronic sinusitis reported epiphora of the left eye for five years. Balloon dacryocystoplasty was attempted but failed. Endo-DCR (Endoscopic dacryocystorhinostomy) was indicated; however, preoperative CT (computed tomography) imaging and nasal endoscopic examination showed sinonasal anomalies and the loss of internal landmarks for localizing the lacrimal sac. Preoperative CT results indicated previous CL surgery. Endo-DCR was performed with the aid of nasal forceps and a 20-gauge vitreoretinal fiberoptic endoilluminator. A six-month follow-up revealed the complete resolution of symptoms and no signs of recurrence. Conclusions: Epiphora might be a delayed complication of the CL procedure. Before performing endo-DCR, ophthalmologists should be familiar with the sinonasal anatomy and carefully assess preoperative imaging to identify anatomical variations. Nasal forceps and transcanalicular illumination can assist in determining the precise location of the lacrimal sac during endo-DCR.<\/jats:p>","DOI":"10.3390\/medicina58010078","type":"journal-article","created":{"date-parts":[[2022,1,7]],"date-time":"2022-01-07T01:14:02Z","timestamp":1641518042000},"page":"78","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Surgical and Anatomic Consideration in Endoscopic Dacryocystorhinostomy of a Patient with Damaged Sinonasal Anatomy Post\u2013Caldwell-Luc Surgery: A Case Report"],"prefix":"10.3390","volume":"58","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7171-193X","authenticated-orcid":false,"given":"Chia-Chen","family":"Hsu","sequence":"first","affiliation":[{"name":"Department of Ophthalmology, Tri-Service General Hospital, National Defense Medical Center, Taipei 114, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4745-4088","authenticated-orcid":false,"given":"Lung-Chi","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Tri-Service General Hospital, National Defense Medical Center, Taipei 114, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bo-I","family":"Kuo","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, National Taiwan University Hospital, Taipei 100, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Che-Jui","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology-Head and Neck Surgery, Tri-Service General Hospital, National Defense Medical Center, Taipei 114, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8403-208X","authenticated-orcid":false,"given":"Fang-Yu","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Tri-Service General Hospital, National Defense Medical Center, Taipei 114, Taiwan"},{"name":"Department of Ophthalmology, National Taiwan University Hospital, Taipei 100, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,1,5]]},"reference":[{"key":"ref_1","first-page":"Cd007097","article-title":"Endonasal versus external dacryocystorhinostomy for nasolacrimal duct obstruction","volume":"2","author":"Jawaheer","year":"2017","journal-title":"Cochrane Database Syst.
