[Development of cholesteatoma in the middle ear ab statu nascendi].

abstract：PROBLEM:Although robust algorithms for registration and segmentation are available, the majority of surgical approaches to the temporal bone are nowadays made without navigation assistance. Beside instrument navigation (IN), functions such as distance control (DC) and navigated control (NC) can be used. This study anal...
