Stereotactic surgery, initially for brain diseases, now uses advanced imaging like CT and MRI for precise targeting. Technological advancements enable frameless systems and improved navigation for neurosurgery and bone surgery.

Area of Science:

  • Neurosurgery
  • Medical Imaging
  • Surgical Navigation

Context:

  • Stereotactic surgery evolved from using atlases and radiographs to incorporating advanced imaging techniques like CT and MRI.
  • Modern stereotactic procedures involve image acquisition, registration, surgical planning, and intra-operative guidance.
  • Technological updates include multi-modal image fusion, 3D visualization, and frameless stereotaxy systems.

Purpose:

  • To detail the evolution and working principles of stereotactic surgery.
  • To highlight advancements in imaging and guidance systems for neurosurgery.
  • To explore the applicability of stereotactic principles in bone surgery and future directions in interventional imaging.

Summary:

  • The core principle of stereotactic surgery relies on the assumption of brain tissue immobility relative to the skull.

  • Key steps include image acquisition and registration, surgical planning using 2D or 3D data, and instrument guidance.
  • Innovations such as CT, MRI, PET, angiography, 3D visualization, frameless systems, and robotic arms have significantly enhanced precision and applicability.

    • Impact:

    • Advanced imaging and navigation have expanded the scope of stereotactic surgery beyond functional brain diseases to include neurosurgery and bone-related procedures.
    • The development of frameless stereotaxy and image fusion techniques reduces reliance on stereotactic frames and artificial fiducials.
    • Real-time imaging and interventional diagnostic imaging are poised to play an increasingly crucial role in future surgical interventions, including neurosurgery.
