The MKM system offers frameless stereotaxy using optical technology, overcoming limitations of traditional navigation aids. This advanced system enables precise neurosurgery, enhancing lesion removal while preserving healthy tissue.

Area of Science:

  • Neurosurgery
  • Medical Imaging
  • Surgical Navigation

Background:

  • Frameless stereotactic navigation systems are evolving for clinical use.
  • Current systems often rely on mechanical arms, ultrasound, or electromagnetic fields, each with limitations like bulkiness, interference, or environmental sensitivity.
  • Existing frameless stereotaxy methods present challenges in accuracy and surgical field obstruction.

Purpose of the Study:

  • To introduce the MKM system, an optically-based frameless stereotactic device.
  • To evaluate the efficacy and advantages of the MKM system in neurosurgical procedures.
  • To demonstrate the combination of the MKM system with keyhole surgery for improved outcomes.

Main Methods:

  • Development of the MKM system, an optically-based navigation tool.

    • Main Results:

    • The MKM system provides accurate image guidance without mechanical arms, ultrasound, or electromagnetic fields.
    • Successful application in 18 neurosurgical cases, demonstrating feasibility.
    • The system effectively guided accurate excision of brain lesions.

    Conclusions:

    • The MKM system represents an advancement in frameless stereotaxy, offering a non-obstructive and accurate navigation solution.
    • Combining the MKM system with keyhole surgery enhances precision in lesion removal and normal tissue preservation.
    • Optical navigation technology shows significant promise for improving neurosurgical procedures.
