Area of Science:

  • Neurosurgery
  • Surgical Techniques
  • Neuro-oncology

Background:

  • Anterior clinoid meningiomas pose surgical challenges due to their location.
  • Extradural anterior clinoidectomy offers a method for optic nerve decompression and enhanced surgical exposure.
  • Safe optic nerve mobilization and early tumor devascularization are critical for successful resection.

Purpose of the Study:

  • To demonstrate the technique of extradural anterior clinoidectomy for optic nerve decompression.
  • To illustrate the resection of an Al-Mefty type III clinoid meningioma using this approach.
  • To highlight the utility of exoscope magnification in complex parasellar surgeries.

Main Methods:

  • A 2D operative video showcasing right optic nerve decompression via extradural anterior clinoidectomy.
  • Subsequent resection of a right Al-Mefty type III clinoid meningioma.
  • Utilized exoscope magnification for improved visualization and maneuverability.

Main Results:

  • Successful decompression of the right optic nerve.
  • Complete resection of the right Al-Mefty type III clinoid meningioma.
  • Demonstrated enhanced surgical field exposure and maneuverability with the exoscope.

Conclusions:

  • Extradural anterior clinoidectomy is a valuable technique for optic nerve decompression and improving surgical access in the parasellar region.
  • The use of an exoscope enhances visualization and maneuverability during these complex procedures.
  • This approach facilitates safe optic nerve handling and effective meningioma resection.
