Endoscopic Dacryocystorhinostomy Using Ultrasonic Bone Aspirator

PURPOSE: To report the results of 15 endoscopic dacryocystorhinostomy (eDCR) cases using ultrasonic bone aspirator (UBA) and evaluate the UBA efficiency in these surgeries. METHODS: 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. RESULTS: All the patients showed complete resolution of the epiphora. There were no complications or recurrences for a minimum of 10 months postoperatively. CONCLUSIONS: 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.

Application of Ultrasonic Bone Aspirator in Transnasal Endoscopic Dacryocystorhinostomy : A Case Report

Transnasal endoscopic dacryocystorhinostomy (eDCR) has been performed with relative ubiquity since the introduction of the rigid nasal endoscope, with multiple reports found in the literature. Multiple techniques have been used for lacrimal osteotomy, including standard rongeurs, laser, radiofrequency and microdrill. The ultrasonic bone aspirator (UBA) has been described for a variety of neurosurgical procedures and was initially studied in orbital and lacrimal surgery by Sivak-Callcott et al. We report a 74-year-old female patient who suffered from epiphora and pus-like discharge of the right eye. The bone of the lacrimal sac fossa was thinned and removed using an ultrasonic bone aspirator. The patient had a significant symptom improvement without any complications related to UBA use. We applied an ultrasonic bone aspirator for a patient with lacrimal duct stenosis and report a successful result.
