Computer-navigated microscopy enhances brain tumor surgery by integrating radiological data for precise planning and resection. This improves accuracy and minimizes risks, especially for deep or eloquent lesions.

Area of Science:

  • Neurosurgery
  • Medical Imaging
  • Surgical Technology

Background:

  • Brain tumor resection requires precise surgical planning and execution.
  • Intraoperative guidance systems aim to improve accuracy and safety during neurosurgery.
  • Computer-navigated microscopes offer potential for integrating imaging data directly into the surgical field.

Purpose of the Study:

  • To investigate the benefits of integrating intraoperative radiological data for brain tumor surgery using a computer-navigated microscope.
  • To evaluate the system's effectiveness in approach planning and tumor resection.

Main Methods:

  • Utilized a computer-navigated microscope (MKM Zeiss) for 53 contour-guided tumor resections.
  • Employed CT and Magnetic Resonance Tomography (MRT) for preoperative planning.

  • Transferred neuroradiologically defined tumor contours into the microscope for intraoperative projection.

    • Main Results:

    • The system facilitated preoperative planning, accurate incisions, and intraoperative detection of lesions.
    • Improved mean registration accuracy from 5.3 mm to 2 mm over time.
    • Enabled precise resection of gliomas, tailored craniotomies for meningiomas, and safe approaches for metastases.

    Conclusions:

    • Contour-guided navigation using the microscope enhances surgical security in brain tumor operations.
    • The system aids in avoiding potential surgical risks by providing precise guidance.
    • Offers improved outcomes for various brain tumor types, including gliomas, meningiomas, and metastases.
