The paper analyzes the authors' initial experience with the Stealth Station navigation system (Medtronic-Sofamor Danek, USA) during neurosurgery for @entity5 and outlines its techniques. Twenty eight @entity1 with various @entity1313 were operated on. Thirteen @entity1 had @entity5 of the skull base ( @entity1653 , @entity3580 , @entity1823 , @entity82 ). Twelve @entity1 showed various @entity5 -forming processes ( @entity11 , @entity2477 , and metastizing @entity189 ). The navigation system ensured resection of these @entity5 . It was used in 2 other @entity1 with @entity11 and in 1 @entity1 with @entity976 for their stereotactic puncture, biopsy, and drainage. The Stealth Station proved to be an effective tool for preoperative @entity129 and their intraoperative guidance. Strict observance of the protocols of preoperative preparation ensures a high accuracy and facilitates search for and identification of anatomic guides. Only in 1 @entity1 with surface @entity11 involving the central gyri, its resection was followed by @entity1269 that subsequently progressed. In the remaining 27 cases, the operation ran smoothly and caused no new @entity16 . The brain-shift phenomenon is the principal limitation of accuracy of the intraoperative system. This problem is less evident in skull-base surgery where the system was effectively used for critical structural location. Also, it can be safely employed for elimination of slight deep lesions to protect the brain and to minimize its injury via approach to a @entity5 through the brain parenchyma.
