title: [Neuronavigator-guided microsurgery for resection of brain tumors].
abstract: OBJECTIVE
  To study locating accuracy for the brain tumors and their peri-structures by the neuronavigator and elucidate the microsurgical effects.
  
  
  METHODS
  65 patients with intracranial tumors were microsurgically treated by the application of Stealth Station and Vector Vision system. The treatment effects were summarized and the neuronavigational accuracy was discussed.
  
  
  RESULTS
  After mean fiducial error (MFE) and sustained accuracy (SA) were satisfied. Total tumor removal was achieved in 63 cases (97.0%), subtotal removal in 2 cases (3.0%). The neurological functions were improved in 56 cases (86.2%), unchanged obviously in 9 cases (13.8%). No case deteriorated and died in the group.
  
  
  CONCLUSIONS
  Navigation systems are reliable and accurate in making microneurosurgical plans for brain tumors. And they can provide tracing of the tumor in the operation and guide the operator's manipulation. The techniques, which help total removal of the tumors and reduce the postoperative complications, are very useful in guarantee operation effects.
