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

ABSTRACT

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.
