Abstract
Objective To sum up the experience of transcanalicular 980nm laser-assisted dacryocystorhinostomy.Methods Retrospective reviewed 11 cases whom underwent transcanalicular laser-assisted dacryocystorhinostomy combined silicone intubation stenting,including 8 primary nasolacrimal duct obstruction and 3 failed external dacryocystorhinostomy.Follow-up time was 5-17 months.Surgery operation and complication were recorded.Results The size of osteotomys were about 3mm and 4 osteotomys were out of good place.Complications included 8 dacryocystitis,and 6 stenosis or obstruction of lacrimal ductule or common canalicular.Significant improvement of epiphora was achieved in 3 cases at last follow-up.Conclusions The transcanalicular 980nm laser-assisted dacryocystorhinostomy have been reported achieve satisfied success rate.However,experiences are needed for adequate osteotomy size,good location of ostrotomy,avoiding common canalicular thermal injury.
