The visible ear surgery simulator.

@article{Trier2008, abstract = {This paper presents a real-time computer simulation of surgical procedures in the ear, in which a surgeon drills into the temporal bone to gain access to the middle or inner ear.

The key contributions in this application are the visualization and interaction models in the context of ear surgical simulation.
