Due to the close proximity of many vital structures in the small operating field, surgery in the middle ear and petrous bone is challenging. Among other things, the facial nerve is exposed to a high risk of injury. In this thesis the novel approach to localize the facial nerve and to control the power of a surgical drill using EMG data from the nerve monitor for ENT surgery was further developed and a surgical assistance system was designed based on it. The intraoperative nerve localization is implemented through a data fusion of evoked EMG data with electrical stimulation and position information of a tracked nerve stimulator. The power control of the tracked stimulating surgical drill takes into account different data, especially the determined position data of the facial nerve and the drill, the EMG data and the intensity of the stimulation current.
