Abstract
Endoscopic laser dacryocystorhinostomy (DCR) enables an obstructed lacrimal sac to be opened through an intranasal approach, avoiding the need for a skin incision. The holmiumtyttrium aluminum garnet (holmium:YAG) laser is well-suited for this procedure because of its properties of fiberoptic delivery, effective bone cutting, and precise soft-tissue coagulation. Efficient bone ablation is particularly important for primary DCR which requires removal of relatively thick bone along the lateral nasal wall to expose the lacrimal sac. Forty-six endoscopic laser DCRs were performed on 40 patients. There were no intraoperative or postoperative complications. The surgery successfully relieved lacrimal obstruction in 85% of patients. Endoscopic instrumentation allowed for the rapid identification and correction of intranasal causes of DCR failure, including ethmoid sinus disease and middle turbinate hypertrophy. Endoscopic laser DCR appears to be a safe and effective procedure which should be considered as an alternative to external DCR for the surgical treatment of nasolacrimal duct obstruction.Keywords
