A case report on the success of endoscopic dacryocystorhinostomy following unsuccessful external dacryocystorhinostomy in a patient with nasolacrimal duct obstruction

Endoscopic dacryocystorhinostomy (DCR) is a surgical remedy for nasolacrimal duct obstructions (NLDO), addressing symptoms like excessive tear secretion and swelling. This article presents an observational case report of a 60-year-old female with persistent tear secretion and a non-healing ulcer below the left medial canthus at the previously operated external DCR site, managed initially with antibiotics and secondarily with closure of the external wound. Endoscopic DCR was subsequently performed under local anesthesia, effectively resolving symptoms and facilitating recovery. Advantages of endoscopic over external DCR include no external scar, lower infection rates, and faster recovery. Imaging aids in precise anatomical assessment. The case underscores meticulous preoperative evaluation, surgical precision, and comprehensive postoperative care for optimal outcomes. In conclusion, endoscopic DCR proves pivotal in revising failed procedures, ensuring functional and aesthetic success in managing NLDO.
