Lee, Kim, and Kwon: Endoscopic Dacryocystorhinostomy Using Ultrasonic Bone Aspirator



To report the results of 15 endoscopic dacryocystorhinostomy (eDCR) cases using ultrasonic bone aspirator (UBA) and evaluate the UBA efficiency in these surgeries.


Fifteen eyes of 12 patients presenting with nasolacrimal duct obstruction were evaluated in the present study. eDCR and osteotomy were performed using UBA (Cusa excel, Integra, New Jersey, NJ, USA) from January 2014 to June 2014.


All the patients showed complete resolution of the epiphora. There were no complications or recurrences for a minimum of 10 months postoperatively.


This is the first report on eDCR using UBA. The surgeries were successful and no complications were observed. eDCR using UBA is an easy, safe and effective technique with minimal heat production, minimal damage to the surrounding soft tissue and quick and precise bone removal.
