Microsurgery of the middle ear requires high dexterity due to the finesse and the extreme sensitivity of the structures involved. Learning this surgery is delicate and is performed at the end of the residency. This work focuses on the development of a mechanical finite element model of the anatomical structures that compose the middle ear in order to design a surgical simulator. The objectives are to provide a versatile tool for learning and training of the surgery by surgical practice, as well as the opportunity to explore and evaluate new surgical procedures related to new technologies such as robotics. The mechanical behavior of the developed model was successfully confronted with observations on human specimens. In order to obtain a simulation tool that takes into account the anatomical differences of each patient, a deformation approach of our mechanical atlas, based on clinical imaging, was implemented. Simulations of the stapes footplate drilling and the placement of an ossicular prosthesis were performed using a haptic interface and a novel rendering approach. This work is thus the first virtual simulator of the middle ear surgery. Finally the tele-operated robot, called RobOtol was incorporate in the simulator to explore new robot-based surgical procedures. In addition, the simulation allows to train the otologists to the use of the robot. This work concerns mainly on the interactive simulation of complex surgical procedures, as well as on the learning and the robotization of the otologic microsurgery.
