Efficacy of Piezo-Electric Surgery for Optic Canal Unroofing: Our Experi- ence with Two Cases

Ultrasonic vibrations have been used to cut tissues for two decades. However, it is only in the last five years that experimental applications have been used routinely for standard clinical applications in many different fields of surgery. Surgically decompressing optic nerve, with the use of conventional drills is associated with greater risk of damage to the optic nerve itself. Developing new & precession bound safer techniques would certainly be beneficial to accomplish this task. Ultrasonic piezo bone surgery is a highly sophisticated device designed specifically for high end precession osseous surgery. In this article we describe our experience in using this device for extradural unroofing of the optic canal.
