Ultrasonic Endoscopic Dacryocystorhinostomy

Abstract

Endoscopic endonasal dacryocystorhinostomy has gained a considerable popularity in the recent two decades with the advent of the rigid fiber-optic endoscope [1, 2]. There are numerous advantages of endoscopic dacryocystorhinostomy (DCR) which include no facial incision, no disruption of the medial canthal tendon, no disruption of the lacrimal pump, less trauma, and feasibility in acute dacryocystitis [1, 2]. Recent published meta-analysis have revealed comparable results with external DCR with lesser risks of infection and bleeding [3]. With increasing understanding, it is clear that among others two major goals for a successful endoscopic DCR are creating large osteotomy and as minimally traumatic as possible. Both of these can be easily achieved with an ultrasonic osteotomy.
