AbstractTo estimate the safety and effectiveness of endoscopic nasal dacryocystorhinostomy in the remedy of chronic dacryocystitis. The clinical data of 105 subjects with chronic dacryocystitis enrolled into our hospital were analyzed retrospectively. The subjects were distinguished into nasal endoscopic group (endoscopic dacryocystorhinostomy; i.e., 51 cases) according to their surgical methods and external-route group (external-route dacryocystorhinostomy; i.e., 54 cases). The therapeutic effect, lacrimal gland secretion function, tear film stability, degree of epiphora, lacrimal passage patency, complications, and recurrence rate were contrasted between the 2 groups. The nasal endoscopic group exhibited a higher effective remedy rate (98.04%) compared with the external-route group (83.33%). Three months postoperation, both groups showed improvements in lacrimal gland secretion function and tear film stability, with the nasal endoscopic group demonstrating more significant enhancement in lacrimal gland secretion function than the external-route group. Six months postoperation, a reduction in the degree of epiphora was observed in both groups, with the nasal endoscopic group displaying a more pronounced decrease in epiphora severity and a higher lacrimal passage patency rate than the external-route group. Furthermore, the nasal endoscopic group experienced lower incidences of postoperative complications and recurrence rates. Endoscopic dacryocystorhinostomy is safe and effective in the remedy of chronic dacryocystitis.Copyright © 2024 the Author(s). Published by Wolters Kluwer Health, Inc.
