Endoscope-assisted microsurgery enhances keyhole approaches by improving visualization and safety. This technique minimizes invasiveness, offering better patient outcomes in neurosurgery.

Area of Science:

  • Neurosurgery
  • Minimally Invasive Surgery
  • Medical Imaging

Background:

  • Neurosurgical techniques evolve to reduce patient trauma and improve outcomes.
  • Advanced imaging aids precise lesion localization and anatomical relation assessment.
  • Keyhole approaches offer precision but face challenges with light and viewing angles.

Purpose of the Study:

  • To evaluate the utility of rigid rod lens endoscopes in compensating for keyhole craniotomy limitations.
  • To enhance visualization and maneuverability during minimally invasive neurosurgical procedures.

Main Methods:

  • Endoscope-assisted microsurgery utilizes rigid lens scopes fixed by a mechanical arm.
  • Surgeons can simultaneously view microscopic and endoscopic images through various display methods.

Related Experiment Videos

  • Five distinct methods for simultaneous image observation are detailed.

    • Main Results:

    • Rigid rod lens endoscopes effectively compensate for reduced light intensity and narrow viewing angles in keyhole approaches.
    • Improved visualization of surgical field details enhances precision.
    • The technique allows for targeted lesion removal through individualized anatomical windows.

    Conclusions:

    • Endoscope-assisted keyhole surgery leverages patient-specific anatomy for precise lesion targeting.
    • Intraoperative use of endoscopes significantly improves light intensity and visualization of critical details.
    • This approach maximizes surgical efficiency and patient safety while minimizing invasiveness.
