title: [Quality securing procedures in neurosurgical operations. Experiences with intraoperative computed tomography and neuronavigation].
abstract: In the department of Neurosurgery of the Unfallkrankenhaus Berlin, experiences with neuronavigation and intraoperative computed tomography were acquired and reviewed on a descriptive basis. The main parameter for the evaluation was target point accuracy for the neuronavigation and image quality for the intraoperative ct. Additionally, both systems were evaluated about the requirement of time, staff and technical equipment. The analysis shows that both techniques are apted for quality control with the operation of intracranial lesions. Most problems with the handling of the new methods decreased with growing experience. On the technical aspect there are still problems with target accuracy for the neuronavigation and image quality for the ct-scans. However, solutions due to future technical improvement are perceived. The increase of time requirement is compensated with the rise of operation security. An even higher quality control is achieved with combination of both systems.
