Simulator for Temporal Bone Surgery

The Visible Ear Simulator (VES) is a project initiated by Mads Sølvsten Sørensen, MD, aimed at creating a virtual tool for providing training in surgical procedures involving the temporal bone. The VES software is available as a free download.


When combined with a commercially available haptic device and a standard PC, the VES provides an experience of drilling a temporal bone that is realistic, sophisticated, and interactive. The user can also identify and interact with various structures, such as the mastoid bone, sigmoid sinus, dura, and facial nerve, thereby enhancing the simulation of real-life surgery. The VES project is a result of a collaboration between Alexandra Institute and Rigshospitalet, University of Copenhagen, Denmark.
