Abstract

The protection of soft tissue structures behind the ablated bone in skull base surgery is mandatory. As the destruction of the membrane lining the inner ear can lead to a damage of organ functions (e.g. deafness or vertigo) a precise bone tissue removal by a laser ablation setup is investigated. For the detection of the boundary between soft tissue and bone the ablation area and rate are monitored by a video camera. Through this the laser is guided across the ablation area by image processing technologies. An aim of this project is a defined, navigated-controlled and laser based bone removal for the future buildup of a robot based surgical laser instrument. This publication describes the setup of our video controlled laser ablation system, initial experiments and results.
