title: Stereotactic and computer-assisted neurosurgery at the Cleveland Clinic: review of 501 consecutive cases.
abstract: BACKGROUND
  Stereotactic and computer-assisted techniques have revolutionized the diagnosis and treatment of many disorders of the brain by directing surgical instruments, the surgeon's hands, or focused radiation to an imaged target along predefined routes.
  
  
  METHODS
  This report reviews the basic principles and techniques of stereotactic and computer-assisted procedures in 501 consecutive procedures.
  
  
  RESULTS
  Procedures performed include biopsy; decompression of cysts, hematomas, ventricles, and abscesses; "point," computer-assisted volumetric, and frameless stereotactic resection of brain lesions; placement of depth electrodes; treatment of movement or pain disorders; implantation of radioactive seeds in malignant tumors; and radiosurgery.
  
  
  CONCLUSIONS
  Overall, image-directed stereotactic neurosurgery proved safe, accurate, and versatile.
