Evaluation of the anatomical accuracy of the neuronavigation system “StealthStation” in neurosurgical operations

description: Stereotaxy was the first well-established and traditionally the gold standard method of targeting intracranial structures. The extensive refinement of the stereotactic devices along with the development of MRI in the 1990s and a large number of relevant publications with consistent results rendered the frame-based stereotactic brain biopsy the gold standard technique for brain biopsies, too. (Hall 1998, Yu, Liu et al. 2000, Heper, Erden et al. 2005) However, the stereotactic method is characterized by various important disadvantages: 1) the patient’s discomfort, 2) the necessity of a new CT/MRI scan immediately preoperatively, 3) the requirement of calculating and verifying the coordinates, 4) the head frames themselves, which may restrict both the anesthesiologist and the surgeon, and 5) the fact that biopsy specimens can be acquired intraoperatively only from the targets defined preoperatively. (Goldstein, Gumerlock et al. 1987, Matsumoto, Tomita et al. 1995, Lozano, Gildenberg et al. 2009, Shooman, Belli et al. 2010) Modern intraoperative navigation systems provide several significant advantages, e.g. multiplanar image reconstruction (axial, coronal, sagittal, probe’s eye view) and 3D pre- and intra-operative planning, real-time intraoperative surgical instrument guidance, and precise localization of intracranial targets. (Bale, Laimer et al. 2006, Georgiopoulos, Ellul et al. 2014) Moreover, in the case of brain biopsies they are combined with miniframe stereotactic devices. As a result, the various disadvantages of the stereotactic methods and apparatuses (e.g. Cosman-Roberts-Wells (CRW) or Leksell systems) can be avoided. In order to perform a brain biopsy, a biopsy needle must be inserted accurately and safely into the selected target. Therefore, a reliable targeting device (stereotactic apparatus or navigation system) is necessary, as well as a device that holds steadily the needle in the pre-specified trajectory as it is inserted, i.e. a needle guide attache…
