Extension of Indications for Transcanal Endoscopic Ear Surgery Using an Ultrasonic Bone Curette for Cholesteatomas

Abstract

The transcanal endoscopic approach to the antrum using the UBC proved to be less invasive and more functional. The UBC contains both a suction and irrigation system in a single handpiece, and this UBC is an appropriate cutting tool that extends the indications for TEES.
