Area of Science:

  • Neurosurgery
  • Minimally Invasive Surgery
  • Surgical Technology

Background:

  • Advancements in diagnostic imaging and microsurgical techniques have propelled the evolution of transcranial neurosurgery.
  • Minimally invasive approaches enable the treatment of complex neurological conditions through smaller, more targeted surgical corridors.

Observation:

  • A 10-year experience with over 3000 patients treated using transcranial endoscope-assisted microsurgery with keyhole craniotomies is reviewed.
  • This technique, pioneered by Axel Perneczky, emphasizes limited-sized openings for surgical access.

Findings:

  • Meticulous preoperative planning, including craniotomy site, size, and trajectory, is essential for successful outcomes.
  • Key preconditions include careful case selection, precise planning, individualized craniotomy placement, and intraoperative endoscopic assistance.

  • Endoscopic visualization enhances surgical control with improved lighting, wider viewing angles, and clear depiction of critical anatomical details.

    • Implications:

    • Keyhole approaches facilitate safe intraoperative control and effective management of intracranial pathologies.
    • The integration of intraoperative endoscopy significantly improves visualization and precision in minimally invasive neurosurgery.
    • This approach represents a significant advancement in treating complex neurological diseases with reduced invasiveness.
