Area of Science:

  • Neurosurgery
  • Medical Imaging
  • Computer-Assisted Surgery

Background:

  • Frame-based stereotactic systems are established in neurosurgery.
  • Stereotactic computers have expanded applications.
  • A novel frameless stereotactic system using computer navigation has been developed.

Purpose of the Study:

  • To evaluate the accuracy and safety of a new frameless stereotactic system.
  • To assess its application for puncturing cerebral tumors and abscesses.

Main Methods:

  • A frameless stereotactic setup was used in 36 patients (39 procedures).
  • Data collected included computer data, surgery time, anesthesia, complications, and diagnoses.
  • Procedures involved biopsies of intracranial processes.

Main Results:

  • Biopsies were successfully obtained from all cerebral lobes, with diagnoses established in all but two cases.
  • Median surgery time was approximately 60 minutes.
  • One postoperative abscess and one intraoperative epileptic seizure occurred.

Conclusions:

  • A new procedure for stereotactic biopsies of intracranial processes using a frameless system is introduced.
  • The system successfully reached all target tumors.
  • The procedure demonstrated a low complication rate.
