This study presents a modified frameless stereotactic neurosurgery technique using infrared neuronavigation and the Fisher stereotactic biopsy instrument. The method proved accurate and successful for various procedures, including brain biopsies and aspirations.

Area of Science:

  • Neurosurgery
  • Medical Technology
  • Image-guided Therapy

Background:

  • Neuronavigation is crucial in stereotactic neurosurgery, offering frameless precision.
  • Traditional methods can be invasive; advancements aim for improved accuracy and reduced invasiveness.

Purpose of the Study:

  • To develop and evaluate a modified frameless stereotactic neurosurgery technique.
  • To assess the efficacy of combining the Fisher stereotactic biopsy instrument with infrared neuronavigation.

Main Methods:

  • A modified technique using the Fisher stereotactic biopsy instrument with a quick-lock holder.
  • Infrared guidance provided by the BrainLab VectorVision Neuronavigation system.
  • Application in 18 patients for biopsies, aspirations, and reservoir implantation.

Main Results:

  • All 18 procedures were successfully completed with accurate targeting.
  • The technique was applied to brain biopsies, abscess aspirations, hematoma aspirations, and Ommaya reservoir implantation.
  • The method demonstrated high precision and effectiveness in diverse neurosurgical applications.

Conclusions:

  • The modified frameless stereotactic technique integrating infrared neuronavigation is effective and accurate.
  • This approach offers a viable alternative for various stereotactic neurosurgical interventions.
  • Further discussion on the advantages and disadvantages of this method is warranted.
